Vivo v5 AT&T SIM was working fine in Newyork but stopped working in North Carolina. AT&T 4G(forbidden)
No service is showing up now even since I moved from New York to North Carolina.
AT&T customer support also couldn’t help. They even provided a new SIM in North Carolina but still same issue.
AT&T 4G is showing as forbidden in phone’s mobile network carrier list.
Is it location specific or any device compatibility issue? It shouldn’t be device compatibility because it wa swirling fine in New York.
