I get lousy service. Phone won't send texts or make calls numerous times. I can here them, they can't hear me. I'll get a text 7 hours after the person sent it. Went to a park next to the YMCA. I tried to send a text and couldn't. I then tried WIFI and was able to use the YMCA WIFI. I get anywhere from 2-5 text messages of the same message just 1 minute apart.

Poor to no reception, it's worst than Sprint after the merger.

Verizon notorious for having no reception half the time in this zone of Alma in 94306. We struggle maintaining 1 bar of service in this area. Thankfully we have good wifi but for being the Bay Area, 94306 a very expensive place to live, cell coverage is surprisingly inadequate. So that's what you are Verizon to me; inadequate. Fix it please

Calls are constantly dropping since early November 2020. Have called AT&T several times, waited up to 53 minutes, and then being disconnected. Very Frustrating with dropped calls and poor customer service with AT&T!

During a 7 hour power outage on Monday, August 7, 2020 I had 1 bar or "No Service" for most of that period. This is very unsettling, particularly during an extended outage, to have insufficient coverage. Text messages kept bouncing back, and internet was unusable.
