I have been a long time AT&T subscriber. I recently switched to Verizon to get the new iPhone 7. Before switching, I checked the Verizon coverage map for my area and it appeared that it was comprehensive and strong coverage.
After receiving my new phone I have had numerous issues:
1. Frequently getting only "1 bar" for signal strength (In field test mode this equates to frequent -110 to -118dB signal strength)
2. Calls are difficult to hear (frequent sporadic reception that makes it hard for others to understand me)
3. Regular transitioning from LTE to 3G speed
I entered a chat with a Verizon rep and he told me that there were "cell towers all over my location" and that he could improve my problem through "syncing" my account with the local towers. I do not know what this means, but he told me he was going to make a change on the Verizon side and then to turn off my phone, reset network settings, and then reboot after 5 minutes. I did these steps and waited a few days but the problem has persisted.
Please help! I never experienced these signal strength issues with AT&T and this is making my experience unstable and unsustainable.
