[Q] how do cell phone unlock services work? - Android Q&A, Help & Troubleshooting

I see so many unlocking services on eBay and can't help but wonder, how do these people even unlock the phones? Is there some sort of program that they have or something?

Depends on OS and whether GSM or CDMA

Are you sure? I heard it differently.
My family possibly be going to Verizon, and I look around. Most if not all the info I seen so far said no.
If there is a way, I want to know. Since I have the SGS2.
Any unlocked phone can be used on any network so yeah you can use it on Verizon

Yes and no, because Verizon uses cdma and not gsm and your phone is gsm based you will only be able to use voice and 2G Data, 3G will not work with your phone.

Guys seriously? Verizon doesn't use SIM cards in order to use a phone on their network you have to use a Verizon branded phone! Sorry no unlocked phones! Sheesh feeding him wrong information could waste him a lot of money!

Is unlocking the GSM radio for AT&T illegal?

I was talking with my friend the other day he is an AT&T regional manager and he said that unlocking my photons gem radio and buying service with AT&T was a federal crime. I do not believe it is but can someone give me some better info on if it is or is not?

Lots of people unlock their radio for AT&T, no one is in jail yet.
I think he just wants me to buy an ATT phone
Sent from my MB855 using xda premium
either he is woefully ignorant or he is lying to you. If he is lying to you, than he is not your friend.
Well he it was illegal because of ESN writing but unlocking the GSM radio does not write an ESN correct?
Sent from my MB855 using xda premium
1. unlocking GSM radio is not ESN writing
2. ESN cloning of another phone you own and have not activated is not illegal (i.e. you are not using 2 phones with the same ESN on a network)
3. ESN cloning of a phone you do not own for the intent of stealing signal is illegal.
Hmmm do GSM networks even use ESN's?

No unlock for other carriers I know its cdma but is it still possisble ?
Sent from my Galaxy Nexus using xda app-developers app
Edit: Doesn't make sense according to person below me but I did my research and that is what I found.
That doesn't even begin to make any sense.
It's carrier locked.
Here in the US you can flash a Razr or other CDMA phone to work with a different carrier.
The new carrier must have the information to update all the tower tables and such. They must also add the MEID/ESN to their database.
Here in the US you can take a Sprint or Verizon branded phone and use it on Metro PCS.

Carrier unlock for the tbolt?

I may go to mexico and I want to get rid of my tbolt, and in Mexico there's a cdma carrier called iusacell.. do I need to unlock the phone (as any gsm phone) so people can activate it in Mexico?
Will they need the sim card?

I have mine flashed to Cricket, but only because I have an older CDMA number that I have been sitting on for years. AT&T just bought Cricket in May, so they are in the process of converting from the CDMA network to the GSM network. So that means all new Cricket activations have to be new GSM numbers and they are no longer activating new MDN's on the old CDMA network. With that said, I believe there might be a way to unlock this device for GSM use. I've seen threads about it. I'd recon all you'd need is the new Cricket APN settings to manually program for data, and I'm sure you can get a hold of that easily. I will have to eventually convert over to their new GSM network too, so I have been thinking about unlocking it using the methods in another thread. If I decide to do so within the next week I'll let you know how it turned out.

Yes u can Unlock it for any GSM carrier and get HSP+ or you can flash(manually reprogram CDMA devices) to any CDMA carrier such as Pageplus Boost Mobile or even old MetroPCS CDMA network..the GSM unlock is the easiest if ur not a custom to flashing devices[emoji4]
