There are two key communication modes used for cell phones. The CDMA system is a coded response system that binds a user and its phone together to a particular system and to a particular number. The CDMA system is used worldwide. The second mobile technology is known as GSM or Global System for Mobile Communication. The GSM system is gaining popularity on a large scale and is the common standard in over two hundred countries in the World.


The GSM phones utilize a SIM card to communicate with a particular network. There is possibility that the phone you use is locked to a specific network provider. In this case your phone will not respond to a SIM card from an alternate provider. When the phone is purchased by an individual, he should have the ability to change the SIM card and use the phone with multiple service providers of their choice. This allows the phone to be used when you go to foreign countries without paying excessive roaming charges.


How to unlock a cell phone?


The first important step is to know the type of phone. If it is a CDMA phone, it does have SIM ...
... cards and the service provider authenticates the number, that’s why it is impossible to Unlock Cell Phone based on CDMA system. Secondly, once you are sure it is a GSM phone, determine if it is locked. The simple way to do this is to insert a SIM card with a different service provider and see if this SIM card works in your phone. If you insert the new SIM card, and the phone thinks it is now the other phone, it is not locked. If it is locked, you will receive some kind of error message.


The final step is to surf the internet and find a reputable unlock cell phone service provider. The company will cost less to email you the code. The code just needs to be entered into the phone to unlock it. You will generally get a rather encouraging message from the phone itself, but in any case, you can test it by using another SIM card as you did in the prior determination process.


Unfortunately, some makes, carriers and models of cell phones cannot be unlocked with a simple code. The cell phone unlock service provides the codes that can see if your model can be unlocked by code or not. If not, send the phone away to fix this issue although this can usually be done rather fast in an emergency.


An unlocked cell phone is must for its owner. The locking of a GSM phone to make it impossible to choose your own provider is an unfair mean. Luckily, this is one injustice that can easily be corrected.
