There are 2 cellular phone technologies that are currently being used by most of the world’s mobile phone service providers. They are the Code Division Multiple Access (CDMA) and the Global System for Mobile communication (GSM). If you have the former your phone is not un lockable, period. But, if your phone operates on the latter, it may be un lockable.

Usually, when you buy a cellular phone, the company that sold it to you locked the phone prior to you buying it, so you are forced to use it only on their network. The result is that you can’t use your cellular phone on another network, even after you have changed the SIM card.

The SIM card identifies your phone to the cellular network. It is especially useful to change your SIM card if you desire to travel to another country so you can have cellular phone access without roaming charges. Although there are services that will unlock your cellular phone for a fee, there is no need for you to pay them. You can do it yourself for free. Then you can use your cellular phone with any service provider anywhere in the world.

It is also good for those who buy a used cellular phone and discover that the phone doesn’t work with their service provider. The US cellular phone users have no choice but to use one phone service provider. The result is that their cellular phone will only work with that service provider.

If you purchase an iPhone 3G at the Apple Online Store you can activate it with any wireless carrier. All you have to do is insert the SIM from the service provider of your choice into the iPhone 3G and activate it by connecting to iTunes 8. That statement makes most people who hate cellular phone contracts especially those that are locked to a particularly service provider very happy. Most people would much rather pay the full retail price for a cellular phone then get locked into a contract. If an iPhone 3Gs that were unlocked had been available when they purchased theirs they would have never committed to a long term contract in the first place just to get a better price.

However, there is some bad news to go along with the good news. One of the few places you can buy an unlocked iPhone is in Hong Kong. The first sentence in the first paragraph is a paraphrased version from the Hong Kong version of Apple’s online store, where the local people can now purchase the contract free unlocked version of the iPhone.

A 16GB one goes for about $798 which is only $100 or so shy of triple the $299 you’ll have to pay for the iPhone if you sign up for two years worth of AT&T service. However, people so hate locked cellular phones and contracts that it may still be tempting to them. Particularly if they may have plans to visit Hong Kong sometime in the near future anyhow.

However, many people already own an iPhone, and don’t need another one. In addition may people are already signed up with AT&T until sometime in the future. Therefore, the only advantage of an unlocked iPhone that is purchased in Hong Kong would be the possibility of using a prepaid SIM card when they’re in another country to avoid AT&T roaming fees. This may seem like an advantage at first but it may not be worth the $800 on top of the $299 they’ve already invested in the iPhone they already own.

Most people will still be pleased when AT&T begins to sell its contract free, retail priced iPhones and would be even more pleased if Apple were to sell an unlocked iPhone for use with any service provider. Most people don’t understand why they don’t already. Maybe they simply don’t see enough of a market, or the service providers that they are in cahoots with demand that only locked phones be available.

The first generation iPhone sold 6,000,000 units worldwide. There has to be a reason. These are some of them.

Price

The original price of the iPhone was groundbreaking and innovative. It was also a very expensive toy. About 50% of the people who were surveyed that didn’t buy an iPhone said that the price was the reason they didn’t. However, at the time of purchase, you now pay a considerably less amount of money up front. The iPhone that has 8GB of memory sells for just $199 which is 1/3 the price of what the iPhone that only had 4GB of memory sold for a year ago. The 16GB model sells for $299.

Browsing Speed

Website pages load up to 2.8 times faster with the 3G capable iPhone. That’s quick. Most people would much prefer to obtain the information that they are looking for sooner as opposed to later. Unfortunately, the 3G wireless service provider plans for the iPhone 3G follows their rather expensive pricing structure, meaning that you’ll have to pay for whatever pricing plan you choose plus their unlimited 3G data services.

The software developer’s kit for the iPhone is now available which makes the potential for future applications along with the iPhone’s existing programs make the iPhone 3G unique in the offering of cellular phones. The iPhone is Still at the Head of the Class

For all the assertions that the advent of the iPhone changed everything in the world of cellular phones, not much has changed in the world of the cellular phones. It’s almost as if Apple is so far ahead in its thinking and innovation that it has an insurmountable lead over its competitors.

However, not everyone needs or wants an iPhone 3G. However, the iPhone 2.0 software upgrade that enables the Application Store to download applications is free to all iPhone owners who are first generation users. In addition, some people may want to hold out for a better upgrade to the hardware, such as a better camera or additional storage. Many people will buy an iPhone 3G. Many others may simply wait for something like 32GB of memory.

In today’ world, life without a cellular phone is almost unimaginable. It is very important to stay connected regardless of where you are in the world.

There are so many service providers that there are numerous choices to choose from. It is important to remember, however, that some service providers lock your cellular phone so that it only works with their service. This makes it impossible for a cellular phone user to change service providers. However, if you own the cellular phone you have a right to get it unlocked in order to use the service provider of your choice. By definition an unlocked cellular phone is one that can be used with any service provider.

There are two types of cellular phones. The first is Code Division Multiple Access (CDMA) and the second is the Global System for Mobiles (GSM). These are two different cellular phone technologies. CDMA based cellular phones are provided by service providers are locked for life. This means that you can’t use them with any other service provider. Therefore CDMA phones cannot be unlocked.

GSM based phones offer you the ability to change service providers through the use of Subscriber Identity Module (SIM) card. There are some service providers who lock GSM cellular phones through use of a software that links the phone’s identity number with the SIM card, so that, it can’t be used with any other GSM service provider SIM. The reason they do this is because they want you to use their service exclusively since they earn money through roaming charges when you travel into regions that are out of their service range. However, these cellular phones may also be unlocked. In fact, most GSM service providers will unlock your cellular phone upon request.

If you own a GSM cellular phone, there are ways to get it unlocked. The process of unlocking a cellular phone is dependent on the service provider and the cellular phone hand set model. The cellular phone can be unlocked by entering a specific code that can be supplied by the service provider, by the service provider, or on the air. There are some cellular phone companies that will only unlock your cellular phone after the initial contract that you signed with them has expired. Usually, after your cellular phone is unlocked it will stay unlocked. The first thing you need to do is determine if your GSM cellular phone is locked. To do this, insert the SIM card from another service provider. If the cellular phone doesn’t work, then you need to contact your service provider and ask them to have it unlocked.

Many cellular phones have a microchip or SIM card which stores subscriber data. This SIM card is issued by the service provider and provides cellular service by activating any phone that it is inserted into. However, a cellular phone that is locked will only recognize a SIM card that is from a particular service provider. An unlocked cellular phone recognizes a SIM card from any other service provider. The software that keeps a cellular phone locked keeps the cellular phone tied to one service provider.

In locations such as the US where the service providers offer discounted or even free cellular phones with their cellular service plans, the cellular phones are usually locked so that they will not work with other service providers. The service providers claim that this is needed in order to subsidize the cost of their cellular phones.

Following some period of time, a service provider may agree to unlock the cellular phone if requested to do so but may charge a fee. As a result of proprietary settings that are may be installed on a locked handset, the cellular phone won’t always function properly with other service providers, even once they are unlocked. Cellular phones should be unlocked following the expiration of the first contract with the user or ideally left unlocked.

One way to have your cellular phone unlocked is to buy it new from a third party vendor in its unlocked, original condition. However, you can expect to pay full retail for the cellular phone. It can be difficult for some consumers to pay expensive prices for a cellular phone if comes free with a service plan. A cellular phone that has been unlocked by a third party should work equally well with any service provider that uses a SIM card.

Cellular phones that are unlocked are in such demand that third party services will unlock your cellular phone for a fee. However, there is no guarantee that the cellular phone will always work properly because they may still have proprietary settings. In addition there are many instructions available online to unlock many models of cellular phones, however, a cellular phone that is improperly unlocked may become inoperable.

SIM cards are used by service providers that operate on the GSM network. Service providers that use the competing CDMA network are not yet using cellular phones that are enabled by a card. The CDMA uses the R-UIM card which is the equivalent of the SIM card.

Although the law requires that many countries sell unlocked iPhones, many people in the US almost never have the opportunity to purchase an unlocked cellular phone from a service provider, which is exactly how the service providers want it.

Cellular phones that are locked are tied to the annual contracts that work in favor of the service providers for numerous reasons. One of these reasons is that the real cost of a cellular phone is lost in the service provider’s two year contracts. For instance, a service provider sells a customer a cellular phone for $99 when its true cost is $599. The cost of the monthly contracts which if added up over the course of 24 months means they will recoup the actual retail price of the cellular phone and more.

In addition, the service providers are exclusively tied to the cellular phone and they make large profits in the numbers of users if they just happen to use one of the cellular phones that they provide the service for. There is nothing that proves this more than AT&T’s deal exclusively with Apple to provide the iPhone to US customers. This one deal alone has gained them millions of customers.

This is precisely the reason why AT&T doesn’t want unlocked cellular phones showing up in the US. Which makes some of the websites on the Internet that are selling brand new iPhone 3Gs that are unlocked complete with the full Apple warranty even more astonishing. While all of the iPhones have sold out, they were going for $799 each and it is still the first time that US customers have had the opportunity to easily purchase an Apple iPhone that is unlocked. There’s nothing illegal about any of this. These Internet retailer’s deals are obtained by importing iPhones from other countries, and these phones were probably purchased in from Taiwan or Belgium, where it is a matter of routine business to sell an unlocked iPhone.

This is still a great deal for consumers who want to be able to carry their cellular phones to the service provider that provides them with the best service. If you want to purchase an unlocked iPhone, keep watching the online retailers because they will undoubtedly get more iPhones in. If only Apple would sell their iPhones unlocked as a routine matter of business it could really make for a better US cellular phone industry. However, with the profits of the service providers being what they are don’t expect this to happen any time soon.
