AT&T
In 20 years, no AT&T investment to improve 3G, 4G, 5G signal strength. With nearest 5G tower over 1.5miles away, my 5G speed is barely 1mbps download and.24mbps upload. This is way worst than previous 4G bandwidth. With an unlimited plan, I get a lot of nothing and plenty of waiting around. Thank you again AT&T

Only one bar at home on both of our phones, but still good connection when driving are walking around. Have not had major connection issues unless hiking on trails in the hills to the West (many dead spots there). Sometimes lose signal from inside a 2016 Toyota RAV4, but on average adequate coverage in Silicon Valley. Note: Previously had Sprint but sometimes there was no reception at a home in Cupertino and spotty coverage elsewhere.

I would get 3 / 5 bars. So far so good. Sometimes would lose signal. Not sure what the cause is. However it is up most of the time.

Good near Ecr and San Thomas as there is a T-Mobile store there. But in my living room it often says no service. I have to go in the backyard and stand in a certain spot. Not fun when it's cold and raining.

Verizon in last two years has worst than metro PCS in this area. I really need to now move on.. I think I waited enough for them to fix it. Multiple Support tickets for this issue. Standard white wash answer from Verizon support folks. This area is subpar coverage area. Seriously..This is freaking hub of technical innovation, heart of silicon valley. not some out in bonny point in Midwest.

I rarely have any problem with AT&T's network (through PureTalkUSA). Both data and cellular works reasonably well at my home.

Been in the area for 4 years... had no issues with the service until a few months ago and it has been absolutely horrible. Calls drop all the time now.

I can't say how many times I have ZERO reception with TMobile. I have called over and over. They have switched out my sim card so many times and then blamed my Samsung 4G! I bought it from them and they would not switch it out. When you can't get reception at Fremont Park to call police when Pit Bulls and other aggressive dogs are chasing / biting kids then what the heck is the point of a cell phone? I took Samsung phone to a cellular / tech guy and he saw ZERO phone issues. PHONE has no issues when I unlocked it and went with AT&T based Cricket. T-Mobile is the WORST! Parents should stay away from this carrier because too many times we have been SOL when we needed a phone.
