Avail SIM Free Mobile Phones and Get Connected With Your Near-Dear Ones

Communication has matured with the invention of advanced technology. The most remarkable addition in the communication technology is mobile phone. As communication becomes the most important element in this modern age, mobile phones have become a necessary tool in people’s life. Now, even life seems aimless without mobile phone, feeling of detachment from friends and relatives comes to the mind. But, nowadays, availing a mobile phone is not at all a subject to worry about. Because, there are numerous mobile phone manufacturers out there in the International marketplace which are offering mobile phones at a very reasonable price.

For surviving in the cut-throat competition in the marketplace, mobile phone manufacturers are offering customers multiple schemes for selling mobile phones. Some of the most popular and best selling schemes are Pay as you go phones, Contract phones and SIM Free phones. Here, in this articles, we will discuss about the SIM free mobile phones and will be exploring the reason behind their huge popularity.

Now in the large marketplace of mobile phones, choosing the right mobile network plan is really difficult. All the mobile network-providing companies are coming with a perfect combination of elegant phones, reasonable price and quality service. But in case of Sim free mobile phones, you will just have to purchase your desirable phone and you will have the full independence to change the network without informing the network provider company. With the technological innovation, there have been the introduction of several communication technologies including the Global system for mobile communications (GSM), Code division multiple access (CDMA), Time division multiple access (TDMA) and Integrated digital enhanced network (iDEN). Among them the most popular technology all over the world is the GSM technology. As all the SIM free mobile phones work on GSM technology, its popularity is also on the top position.

The people of United Kingdom do prefer pay-as-you-go mobile service and contract mobile phones for availing a compactness of mobile phone with the network connection. But, SIM free phones are a bit different from all these kind of phones. By going for SIM Free Mobile Phones, the user is not bound to avail a mobile connection from any particular network. He will have the full rights to choose a network provider according to his own preference. Here it should be mentioned that SIM stands for Subscriber Identity Module which is basically a chip that connects mobile handset with the mobile network. With the pay-as-you-go and contract phones, one has to take a fixed network service which is being offered by a particular schemes. After availing phone under contract schemes, users if not get satisfaction after few moths then he will not be able to switch over to other network provider. But on the other hand, by going for SIM free mobile phones, users need not face this kind of discrepancy. They will have the full independence to switch on to any other network provider without informing the previous service provider or the mobile company. These kind of phones are also different from the Pay-as-you-go phones. Under the scheme of pay-as-you-go phone, with the handset users will get a particular network connection. Though the users are not bound to continue that service for a time period, he will be free to discontinue the network service and switch over to other network.

Now almost all the giant mobile manufacturers are offering SIM free mobile phones. These include Motorola, Nokia, Samsung, LG, Sony Ericsson name of a few. In this current era of advanced technology, all the SIM free mobile phones are equipped with innovative design, attractive looks, world-class user-friendly features and high-quality technology. To survive in current cut-throat competition of the modern marketplace, manufacturers are now offering the elegant mobile handsets at a very reasonable price. That’s why customers do not need to bother about the quality and price while choosing their favourite mobile phone.

Online mobile phone shops are now the perfect place for availing a best offer of SIM free mobile phones. There are various online shops which give mobile phone offers with variety of attractive gifts with purchase of these kind of phones, which include discounts, free gifts, free SMSs and so on.

Mobile Application Development – Current Technologies

Smartphones are a huge success story of the past two decades – and the devices get more powerful each year. Many businesses achieve significant benefits by using mobile technology – including those in both industrial and commercial markets. Deploying applications to mobile users involves a unique set of challenges and choices.

This article provides a background on the current mobile technologies available.

Types of Application for Mobile

The fundamental consideration with delivering business applications over mobile phones is the huge number of devices, and the wide variety of features on these.

Successful mobile application development often involves a combination of technologies and techniques. This is where a diverse skill set, together with an understanding of the mobile landscape, is essential to provide businesses not only with development services but also effective guidance in this time of accelerating change. The challenges at this stage in mobile technology are mirrored by an ever-increasing range of opportunities for businesses to implement new and improved processes.

In general, there are two main approaches to delivering business solutions over mobiles:

(1) Web

The mobile Web has undergone enormous advances over the past few years. According to recent research, around a third of adults in the UK are now using a smartphone – it seems fairly safe to assume that this will only continue to increase. Many more mobile users have some kind of internet access. Although the functionality of mobile Web browsers is now at a good level, there are still considerable restrictions in terms of network connectivity and speed – this is expected to improve over the next couple of years as 4G kicks in, but for the moment remains a serious constraint.

Many organisations create mobile versions of their sites and Web services, with minimised content designed to cope with mobile hardware and data connectivity limitations. One potentially valuable prospect in the mobile Web will be the advance of HTML5. This technology is still very much under development, but with major sites such as the Financial Times opting to use it rather than targeting specific mobile platforms it does look very promising. HTML5 offers a range of benefits including facilities for offline support, multi-media, interactivity and location awareness.

(2) Mobile Apps

Native mobile applications are software solutions deployed directly onto devices such as phones. Many mobile applications link to internet services, with the application, or “app”, handling user interaction natively. Mobile apps have the advantage that they provide a deep level of interactivity that is suited to device hardware – for example, using gestures or sensors like GPS. The difficulty with using mobile applications to deliver business services is the range of platforms in operation. As of early 2011, Google, Apple and RIM together occupy around 90% of the smartphone market. However, the mobile landscape is still in a state of change and there are other players including Windows and Palm – it would be unwise to make any predictions about how market share will look even in a matter of months as things stand.

Microsoft have replaced the Windows Mobile system with Windows Phone 7, with an increased focus on consumer use. Although Microsoft currently has a reduced position in terms of smartphone market share, the upcoming Mango release is looking very promising, and is being received quite well in early testing.

In terms of technologies for mobile apps, the list is long, and depends on which platform (or platforms) you choose to target. Among the most commonly used programming languages for mobile applications are Java, Objective C and C++. Each of the major platforms has a specific Software Development kit, with its own tools to help with the design, testing, debugging and deployment.

The complexity of mobile application development is such that targeting even a single platform involves extensive testing. Some businesses maximise on development resources by balancing native user interaction with cross-platform resources at the back-end, in which case a mobile app can effectively function as an interface for a Web application.

SMS

Aside from targeting specific mobile platforms through software and Web development, there are additional ways to exploit mobile contexts for some business processes – SMS is one such case. In this model, services are delivered as SMS text messages. This has the benefit of generally working across all phones, and payment can be handled via users bills – but it’s a very limited form of interaction. SMS also has a problem that message delivery is not guaranteed. Integrating SMS message handling into Web applications is quite simple – and support for processing SMS messages from users is widely available.

About Android

Google’s Android operating system is going from strength to strength at the moment. Having initially been seen as a platform of interest mainly to geeks, Android now occupies around a third of smartphone market share. Android’s growth is partly down to the openness of the platform, which is available on phones across the market range and from various hardware manufacturers, making it accessible to a more diverse range of users than iPhone.

Apps available through the Android Market are also subject to very little control, which produces a great deal of variety and flexibility but naturally results in a higher proportion of poor quality applications in circulation.

Google’s approach is the opposite of Apple – which retains significant control over its mobile phone operating system. Google’s initial idea was to make a new phone operating system which would be open and free. Their hope was that this would encourage innovative development of both phones and applications. Google has invested in Android because it expected that Web searches would increasingly happen on mobiles, and it wanted to be able to advertise to mobile users.

Although Google’s position within the mobile world seems very strong right now, it is still difficult to say how things are going to progress. In terms of users and applications, Android has, in the past, been seen by many as more focused on consumer services than enterprise use when compared with Apple and RIM, but there is some evidence that this is changing. The Android system is offering a good level of integration with business services such as Microsoft Exchange, and the open nature of the platform makes integrating with existing enterprise applications potentially less troublesome than for certain competitors.

About iPhone

The iPhone was of course in a dominant position as the advance of the smartphone took shape, and the platform is still in a very powerful place. Although business users naturally tended toward Blackberry in the past, both iPhone and Android have continued to make considerable headway for enterprise as well as consumer use, while Blackberry has started catering more to the consumer user as well. The result is that all three of the major smartphone platforms are now occupying some of the same space.

The iPhone offers support for external business utilities such as Microsoft Exchange and, unlike Android, iPhone apps are subject to serious vetting before users can deploy them. The natural downside to this increased level of control over the platform as a whole is a lack of flexibility, but for business applications the plus side is a very high guarantee of quality and reliability for the end user – and ultimately for any business processes being implemented through the technology.

With the hugely popular visual designs and interaction models the brand is famous for, the iPhone is certainly an attractive platform for commercial applications. Apple have been responsible for developing innovative features whose success has prompted other platforms to emulate them, such as multi-touch interaction.

There are some serious considerations with iPhone development:

Apple does not permit users to directly install applications onto the iPhone – all applications must be bought from the Apple Store, and Apple takes a 30% cut. There may be some way around this in the future, but at present we are not aware of it.

For certain applications the fragility, financial value and battery life of the iPhone may pose problems.

Of course, these obstacles apply mostly to commercial / industrial applications. They are not particularly a problem in terms of creating end-user applications. Blueberry has the Objective C skills necessary to develop iPhone programs, and we would be very interested in discussing this with customers.

Although iPhone has lost considerable smartphone ground to both Blackberry and Android, it is generally still seen as the platform to beat, and continues to be a market leader in many ways.

About RIM Blackberry

RIM’s Blackberry platform was long regarded as the mobile system of choice for business and professional users, a perception that still persists to a certain degree. Over the past few years Blackberry has also made significant advances in the consumer market, introducing handsets that have proven especially popular among young smartphone users.

Like Android, Blackberry hardware is very varied, so users can access mobile sites and applications via differing screen sizes and controls – increasing the complexity in any development project. The Blackberry platform delivers a wealth of enterprise services as standard, with Blackberry Enterprise Server seen as a major asset for corporate users. Email on Blackberry is particularly strong, so users who are dependent on a high level of security and reliability in messaging (and communications in general) naturally tend towards this platform.

While iPhones are focused on touchscreen interaction, as are Android devices to a slightly lesser degree, Blackberry handsets are most likely to provide hardware keyboards for text input. This can be a key aspect in the potential of the platform for certain application categories.

A possible issue for mobile Web applications targeted at Blackberry is that the Web browsers on the system have, in the past, been significantly less advanced than those on both iPhone and Android. However, more recent models have addressed this issue by including the latest WebKit browser

Native apps can be deployed through the Blackberry App World marketplace, which has, to date, not occupied as central a role for users as the app stores on iPhone and Android, although the brand is clearly focusing extensive efforts on developing this aspect of usage.

About Windows Mobile

Windows Mobile and Windows Phone 7 represent Microsoft’s foray into the mobile world, which has enjoyed varying degrees of success in the consumer and industrial markets.

From the consumer point of view, at the moment some of the high end smartphone brands such as HTC and LG are producing handsets with the Windows Phone operating system deployed on them, with networks including O2 and Orange providing mobile services. Nokia and Windows have reached a major deal in which the manufacturer is dropping its Symbian platform entirely to focus on Windows as its operating system of choice.

In 2011, Microsoft is due to release a major new version of the mobile Windows platform named Mango. This much anticipated release could alter the position of Microsoft drastically within the mobile world, partly on account of the Nokia partnership and partly since the system is set to include a number of new features such as increased support for HTML5.

At the same time, Windows Mobile has also been adopted strongly by manufacturers of industrial PDAs and mobiles – portable computing device products designed for commercial rather than consumer use. This has seen Microsoft exploring various industrial contexts for mobile processing, with Windows Mobile 6.5 particularly successful in such environments, and hardware produced by various manufacturers including Motorola. Windows Mobile is therefore a natural choice for many mobile workplace needs, including warehouse and delivery services.

From a development perspective, Windows Mobile has very strong advantages. Microsoft has provided a rich platform of development tools – including the C# language, which is much easier to use than C used on other mobiles. Microsoft also includes tools for communication between software on the phone and central servers, and they even include a small database engine.

The strong development tools and wide availability of different devices make Windows Mobile a particularly valuable platform for delivering business applications. At Blueberry we have a uniquely high level of expertise on Windows Mobile systems, so are well positioned to deliver solutions on this platform.

How Charities Can Embrace Technology – Working With Tech

In the first part of this article we looked at the ways in which technology such as mobile communications, computing and the internet can help charities spread their messages and reach their potential sources of funding and aid. However, all of these technologies can also have more direct applications for some charities by actually assisting the work that they carry out.

The speed with which data can be shared between, not only fixed locations over extensive wide area networks and virtual private networks, but also over wireless technology, smartphones and 3G connections from remote locations and on the move, has unleashed numerous possibilities for charities to become more effective and efficient in the work that they carry out. Charities that reach out to the vulnerable can be more responsive and can more easily take their work to these individuals rather than waiting for them to come to the charity. Furthermore technological advances can be employed and promoted by charities as solutions to help the vulnerable become self sufficient, empowered and integrated into society.

Efficiencies in Health Care

One particular field in which many charities operate is healthcare and, although technology in this area is often at the forefront of technological advances in general, such high technology as scanners and robotic surgical devices, which are revolutionising the effectiveness of both diagnosis and treatment, can be very costly.

However there is massive potential for technology, particularly mobile technology, to overcome many of the obstacles faced by carers and healthcare workers, especially where there are issues relating to location. A great idea of how creative combinations of existing technologies can be used to increase efficiencies in this area can be taken from the recent adoption in some hospitals of robots on which tablet computers are attached providing video conferencing facilities. These mobile face to face communication tools, which can be used at the patients bedside, allow consultations to occur between patient and doctor even when the two parties are in different hospitals. This not only makes the hospital efficient (the cost is not small but is less than employing extra staff), to the benefit of all its patients, but also ensures that the patient receives the best possible care, and in good time too, even when the most appropriate doctor for their ailment is located in a different hospital.

Mobile Devices in the Field

As mentioned in the previous instalment of this article, mobile devices can be vital tools for in the field to provide a commentary on the work being done and the conditions being faced by charity workers, but these channels of communication can also be invaluable in allowing charity workers to share information between themselves instantaneously and on the go so that the demands of the vulnerable and in-need can be responded to most effectively and speedily. For example, international charity workers who are treating patients in the field can communicate symptoms to colleagues based in a central location, using mobile phones, text messaging, instant messaging email and even video, so that the diagnoses and treatments can be determined remotely but then implemented on location, straight away. Alternatively workers can use these mobile technologies to arrange and change logistical planning whilst in the field, to respond dynamically where the need is greatest by communicating and researching the information they need as they go.

HP Portable Printers – Technology and Mobility in One

3G Technology on Mobile Phones

Third generation technology, better known as 3G technology has hit the United States and is here to stay. What 3G doesn’t do is have an obvious impact on the look, fell or design of a cellular phone. However, what 3G does dose is promise faster communication services which include fax, voice, and even internet services. This can be offered 3G uses seamless global roaming. New multimedia entertainment and applications are able to be used to their maximum capability because of the 3G network. The first 3G network was actually released in Japan, and is now offered in the United States by companies like Cingular.

Along the same lines of 3G technology, Verizon has decided along with Sprint/Nextel to offer their own version of 3G services but is called Ed-Vo. Other companies such as T-Mobile don’t plan to roll out this technology with their services until 2007. So what is 3G technology exactly? This technology will bring wireless data services to your phone like you’ve never seen them before. This technology boasts speeds about three times faster than a 56 Kbps connection to 2.4Mbps connection speed, equivalent to using a cable modem. 3G networks allow users to easily and quickly read through web pages, watch streaming music videos, and use video conferencing to its fullest.

The experience you will have while using 3G technology with a cellular phone will be one close to using your home computer with a broadband connection. It seems that hand held computers are definitely the way of the future. With each company committing to spending billions of dollars to upgrade to a 3G network, this technology is surely worth the price we will all undoubtedly pay. But with a loss each company will take to upgrade, comes a need to gain customers, so look for new and improved handsets to launch when your favorite company upgrades to using this system.
