FAQS:
What is GSM? Is it different than normal cell phone service? How do I know if I have GSM or not?
GSM is a type of digital mobile phone service. The more common type of digital mobile phone service in the US is CDMA, but just about every other country in the world uses primarily or only GSM. For you as the user of your phone, there is no difference at all between using a phone on a CDMA system or a phone on a GSM system. Unfortunately, the two different systems are not compatible with each other. If you have a T-Mobile, Cingular, or recent new M-mode type service with AT&T, then you have GSM service. How do I know if my phone is already unlocked or not Easy. Borrow a SIM from a friend who has an account with a different wireless service provider and see if it works in your phone or not. If it works, and your phone thinks it is his (or her) phone with that phone's number, then your phone is already unlocked. But if it creates some sort of error message and doesn't work, then your phone is locked. Is it legal to unlock my phone It is your phone, isn't it? Then surely it is as legal that you unlock your phone as it is that you give it away, lose it, break it, leave it turned off, or do just about anything else with it! Unless your phone service contract says 'this phone remains the property of us (the service provider) and you agree not to modify or alter it in any way' then there would seem to be no reason why you can't legally do anything you like with your phone, just so long as you're not attempting to defraud anyone. It is illegal, in some countries, to change the phone's IMEI (serial number) - this is a type of what is called 'cloning' and, particularly with non-GSM phones, could enable you to then pretend to be someone else and have your airtime charged to someone else's account.
How do I know that my phone has been successfully unlocked
Usually, after entering the unlock codes
, the phone will say something that sounds sort of encouraging. Do the test in the question two above. Borrow a SIM from a friend who has an account with a different wireless service provider and see if it works in your phone or not. If it works, then your phone is already unlocked, but if it creates some sort of error message and doesn't work, then your phone is still locked. I've unlocked my phone, but when I turn it on, it still shows the name of the previous wireless service This logo (called a 'splash screen') has been programmed into your phone by the company that sold it to you. It doesn't mean anything about which company now provides you phone service. Unlocking your phone removes the electronic restriction that prevents your phone from working with other SIMs from other wireless services. It doesn't change your splash screen. The good news is you can get rid of the splash screen without needing to unlock your phone. See if you can find in your phone's manual how to change the splash screen, or consider calling the phone manufacturer and have them walk you through it.
How do I know if my phone will work internationally
US GSM cell phones work on 1900 MHz (and sometimes also 850 MHz). Most other countries have GSM networks on 900 or 1800 MHz.
Will I have to unlock my phone every time I change SIMs
No. Once your phone is unlocked, it remains permanently unlocked, no matter what you do to it, unless you specially program back the lock code into it. Will my existing service still work with my unlocked phone Yes, your existing service will work perfectly with no change, as long as you leave your present SIM in your phone. |
