it is when you have to press 2 buttons on your phone (depending on what type of phone you have) and nothing happens when you press any of the buttons until you press the 2 numbers again.
Depends on if the phone is locked to a certain provider or not.
Only if the T-Mobile phone is unlocked. If the T-Mobile phone is still locked, only T-Mobile SIMs will work.
An AT&T sim card will not work in an T-Mobile phone as it is locked to particular carrier itself... If you want to put your AT&T sim in your T-Mobile phone you can try unlocking your phone
you have to go to a mobile phone shop eg. vodafone, o2 etc. and they will unlock it for you.hope this helpsxx
If the T-moblie Phone is locked no if unlocked yes. try it.
I want to unlock lg p500 phone which is locked to virgin. need unlock code.
Unlocked mobile phones enable you to choose which service provider you use. This Enables you to find the best deal available for phone charges, rather than being stuck with the network that has locked the phone.
I have that one scenario when I had locked my phone. What I did was, I removed my battery and wait for an hour and I got my phone back in but if this doesn't work it's better if you bring your phone to the nearest mobile station or technician to check your phone.
No - the phone is the item unlocked - not the SIM card. If you were to replace the Optus SIM card with (for example) a T-mobile SIM - it would register to T-mobile. You could swap the SIM card back with the Optus card, and still use it.
just go to your local phone shop, if its a cell/mobile, they can unlock it with their computer, for i a fee usually, but its not that much.
I have the same problem....
What definition of unlock? • Unlock a locked sim? • Unlock the phone for use with T-Mobile
