Hi, all,
I have a quick question:
I was in Smith, Nevada recently, using a G1 with a Tmobile SIM card, and the phone did not get service. However, the phone did say that there was an ATT network present, and my friend's phone got reception just fine. However, when I tried to manually switch to the ATT network on my phone, I got a message saying that the sim card does not allow me to register on the network. How can I make the phone register on the ATT network when there is no Tmobile service?
Thanks,
Tekgek
Allow roaming? Best answer I got.
You could buy a cheap pay as you go att phone and swap the sim in yours.
Errrm, I think roaming is enabled. Is there a hack or something that can override the sim card's programming?

I have a xda11s i have used the sim unlock tool it works but its not leting me phone out or letin me get incoming calls i think it is that i am using a pay as u go sim on a post paid phone is their any way i can get it from postpaid 2 prepaid
thanks
I don't think that sim and/or phone can be prepaid/postpaid. This is GSM netowor invoicing system, and has nothing to do with phone nor SIM.
Insert your SIM into different phone and check, if you have same problems. If so, call your operator.
I use Cingular Go (Prepaid) with my SX66 ... no issues at all. You may have some issue specific to your sim (it may be corrupt or damaged). Just my thoughts on it.
it not depends on payment type...simlock means, that the phone is coded that it'll accept sim from the network provider who sold the phone...
Unlocked my Tilt from ATT to use with a T-Mo SIM card. Reboot after SIM install gave me an "E" and I could make and receive calls.
Now however, just minutes later, I am getting no service on the T-Mo network and wonder whether I am missing something.
Lil help?

Is the phone sim unlocked? I don't know how it works with Sprint but that would be the case with GSM providers
If it's Sprint, it's CDMA.AT&T and T-Mobile are the only GSM providers in the US. However, it should work there if you get the SIM unlocked. The SIM unlock code is formulated based on the IMEI, so there are three ways to get it:
From Sprint. Probably the simplest, but tricky if you're not the phone's original owner.
Pay a site or unlocking service with the algorithm that decodes it from the IMEI. Usually runs around $10-$20.

You can also try this app, but it only works on rooted phones running the original ROM:

Good luck.

Bro, A CDMA PHONE CANNOT BE UNLOCKED. IT WON'T EVEN WORK ON ANOTHER CDMA CARRIER LIKE VERIZON. ONLY SPRINT SIMs WILL WORK.
Make sure u buy a GSM phone if u plan 2 use it on another carrier.
But the phone uses GSM! It picks up the network here but I just cant get the unlock box

Then it simply isn't a Sprint handset. CDMA phones can only work on that particular network. The phone is custom-made just for that network
Any help is greatly appreciated.
I have the phone rooted with the SIM unlock. The phone will allow me to pop In a T-Mobile SIM card and search for network. But... When I pop in an at&t sim, the search for network function is greyed out and unable to be clicked to find the att network and connect. Any reason why a tmobile SIM works but a at&t SIM does not?
The AT&T sim card inserted can receive calls and texts, but it will not allow me to make a call or send a text back. It shows limited service and no signal.
Thanks in advance
happens to me too. what did you figure out?
Hey Everyone i just picked this prepaid phone up at target it was a virgin mobile prepaid, i got it to replace my broken Sprint phone and i noticed that the sim card that came with the Virgin mobile phone is also sprint. so i just put my Sprint Sim Card in and i cant seem to get mobile data to work at all. i noticed when i go to the mobile data settings and select 4G settings it says HTC and not Sprint any ideas and there isnt an option to add a APN. i thought that since it comes with sprint sim card that i would just be able to use my sprint sim card, you know just plug and play and no luck. also i never activited that sim card through virgin mobile cause i didnt need it cause i have my sim card.
