Unlocked T-Mobile HTC One w/ AT&T GoPhone Sim

Hi everyone.

I just unlocked my T-Mobile HTC One and popped in my working LTE | At&t GoPhone sim. But unfortunately, the network signal has been very unstable. Going from full bars to 0, 2G, 3G, etc. Is this happening because when I flashed my custom rom on my HTC one I chose T-Mobile? Did anyone had to flash to AT&t HTC One or International HTc One?

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

Thanks

Update:
After my 3rd call to GoPhone(AT&T) sim was locked to the first device, now it is unlocked and working on any device.
