SM-G950U AT&t network problem (not by gcpro)


I bought this phone for my wife 2 mounths ago, phone was locked.
I tried to unlock with GCPro but no luck. Then I used this service "INSTANT REMOTE UNLOCK CODE AT&T" on Ebay It worked, but after a couple of days I noticed a problem:
when the phone is in one place - the connection to the network is stable, but if you go to another place (as I understand it when one cell tower is switched to another) - the network antenna disappears, the signal level is -101db, outgoing\incoming calls are not possible, no data. Helps only airplane mod on\off or reboot. I tried different firmware, set different network modes, etc - nothing helps.
Maybe someone knows how to solve this problem,
I need help because I'm already tired of this phone.

Hello
GCPro already support this model via code read qcom via credits only. its 100% safe.

If someone else unlocked it with something did he read code for you or erased and write cert ?
if cert is erased and rewrite you will face network issue always. no permanent fix for it. temporary fix is write working phone qcn. until it's formated or reflashed it will work.

I was not given an unlock code, so most likely he erased and write cert in my phone. I just saw the phone reboot 3 times and then a message appeared on the screen "Network Unlock Successful". All took about 10 minutes.

There is a new tool called *******s. They charge very low credit. But the method is look like rewriting cert to the phone. And please don’t use this tool. It going to screwed your phone and there is no support.

GCpro is always the best

I’m really appreciate GCpro support that trying to help other people even they use different tool

This is the perfect example how those "cheap remote unlocks" are just that, crap.
You may have saved a few bucks, but now you're wasting hours of time searching and researching for your signal issue.
I would never entrust my phone for someone messing with it remotely, both for reliability and security reasons.
I guess to each their own.
