Unlocked my HTC One now doesn't work
Hi everyone, I just unlocked my T-Mo HTC One and not sure whats the problem but my At&t GoPhone sim is just not working (no network no signal) and when there is for a few seconds I see the 2G symbol or G symbol and goes back to X.
I can't say the unlock went wrong because I entered the unlock code and my phone picked up the Att GoPhone APN settings on its own.
My StraightTalk Tmo Sim works on HTC One but At&tGoPhone sim is not really retrieving signal but it detects the GoPhone APN automatically which are correct. ST Tmo sim card & GoPhone sim both work fine on my Unlocked Tmo iPhone5
