No 4G LTE service, only 3G service
I have a Galaxy S9 and since a software update three weeks ago, I have not been able to connect to 4G LTE. Every few minutes all day, my phone refreshes the data searching for LTE and then settles on 3G. I live in New York City and I have asked Boost agents multiple times about the problem. The cell towers are fine in my area, nothing is wrong with my account. I have tried just about everything possible. I have done the ##72786# method, updated PRL and Profile, reset my phone, turned on airplane mode, removed and reinserted my SIM card, checked the LTE towers near me, and finally factory reset my phone. Nothing has worked. I went to UBreakIFix and they suggested that maybe due to the Sprint & T-Mobile merge, my phone's antenna cannot pick up LTE service anymore. I honestly am out of options to try and restore my LTE service. Any suggestions would be really appreciated. If nothing else works, I really would like to be sent a new phone because this is ridiculous.
