ATT with G1 with Tmobile SIM card?

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?

[Q] Unlocked ATT device no signal after switching SIM

Hello.
I have an Atrix HD from ATT, I bought it unlocked at Ebay. I used it with my ATT sim Card, then with Movistar in Colombia for vacations and everything was working great. Then I came back to the US, used a T-Mobile sim card and now I can not use any other sim card. The only one it accepts is the T-Mobile one and it works fine. If I pop any other sim card it gives me no signal (a white cross appears in a red circle where the circle bars should be).
My phone is rooted but I have not flashed any ROM or done anything else beyond installing Superuser and Titanium Backup. I already did an internal and an external reset and none works: The only sim card that gets signal is the T-Mobile one. Called T-Mobile and they said they cant help me since the phone is not supported.
My hint is that somehow the T-Mobile sim card switched my frequency bands. Whats funny though is that now I am in Colombia and when I insert the T-Mobile sim card and check which network is my phone connected to it shows Movistar and the signal bars are great. If I pop up my Movistar sim card it gets no signal at all.
Any help will be greatly appreaciated.
You must have setup the sim card lock disable that and then try putting in another sim

XT1060 stuck on 3G

I have a XT1060 with Bootloader unlocked via Sunshine. I have flashed all kinds of ROM on this thing in the past and finally it has the standard VZW 4.4.4 image on it with factory reset. A friend of mine lost his phone and I gave him this phone to use as a temp replacement and he reported it only shows 3G with a new Verizon sim.
I have a VZW Dev edition XT1060 also as a daily driver, so I took my sim card out of my phone and put that into the backup device and sure enough, it always shows 3G and Mobile Network Type as CDMA -eHRPD and my regular phone always shows LTE with the same sim card. I also checked that they both are showing System Build Number as KXA21.12-L1.26.1
Is there a way to fix the old phone, i.e., reset the internal radio or something so that it gets LTE?
TIA

Help with 4g possible sim card issue

So I have the droid turbo I recently started having issues with no 4g only 3g I can force 4g through the phone info screen *#*#4636#*#* and it will switch over but only for a minute then completely losses all signal and the signal I did get before would be full bars. I tryed flashing stock via fastboot that didn't change anything any ideas I'm thinking sim card and if so is there anything I can do short of ordering a new one.
You can try reseating the sim card in the phone. Otherwise go to VZW store or get online and request a new one.

any ideas no Mobile data?

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.
