Porting unlocked T-mobile Huwei Comet Phone to AT&T
After much talking with AT&T technical support I was going to give up and send back my new SIM card, but I got it working. Here is the story.
I have a T-mobile Huwei Comet pay as you go that I used to roam onto AT&T networks during frequent travel outside of T-mobile coverage. In December data roaming was cancelled without notice. After many hours with T-mobile support that was the outcome. So T-mobile gave me the unlock code and I bought an AT&T SIM on the web and unlocked and activated the phone. The phone worked fine but no data. After much time with technical support from AT&T and an attempt to give me an APN to type in it still didn't work. But I have found that minimal info is needed for the data to work. Just go into
Wireless & networks
Access Point Names
Then add a new APN with the following:
Name: ATT WAP
Everything else should be left blank or unchanged.
Go to menu and Save.
Then Back up to Network operators and pick AT&T. This step may not be necessary. Maybe you just need to turn the phone off and on again. Anyway, that is it, and it now works.
