It seems like my AT&T cell coverage has become extremely erratic in the past few weeks. When I am inside my home it keeps switching to no service. Cannot receive calls, texts except over wifi. This has happened over last 2 weeks. The phone works fine elsewhere outside the cupertino / house area.

Inside or outside my house coverage is spotty. I'll see 4 bars on my phone, but by the time I'm done dialing it's down to 2 bars, so who are they kidding. It's marginally better than AT&T, my previous carrier. But Sprint still gives me dropped calls, very poor voice quality, and times when it takes 4-8 hours before I receive a text or voice message. Bottom line, I'm looking for a new carrier. Right now T-Mobile is in the running.

Just moved from the mid west where we never had cell problems. Amazes that here by Apple the internet is super slow and cell reception is very poor

I agree with the October 19 2014 review of poor AT&T coverage outside Cupertino Library. Calls drop very easily here, despite a visible cell tower on City Hall!

We changed to Verizon from AT&T to get better reception. However, Verizon is equally poor. Many dropped calls and poor connections. It seems ironic that we live in the heart of technology and can't get decent cell coverage. My contract is about up and I don't know where to go next!

I actually use Virgin Mobile over the Sprint Network. Connections are ok. Texting and data are much more reliable. I'm thinking of switching over to Sprint since it worked pretty well when we went to Hawaii (Oahu and Kauai). I've had AT&T previously. They were famous for dropped calls and barely 2 bars even outside. They put up an additional tower nearby so service is improved now. Too expensive for what you get.

Near Cupertino library, 90% percent of international call var Skype or Google hangout dropped. Very poor wireless coverage, ironically it's the Hq of Apple, an area with highest expensive power.

Reception is horrendous. A lot of new construction going on around Valley Mall, residential AND commercial. AT&T is going to have a lot of unhappy customers new to the area if they don't improve it soon. It boggles the mind that construction for the new Apple Headquarters is going on just across Hwy. 280 and AT&T hasn't done a thing.

Service was good for a long time. Things have changed since beginning of 2014. All our phones inside the home get a DOT / bar - outside may be 2. But the audio is scratchy and had to repeat several times. Checked with VZ support and did what they recommend me to do. Nothing has improved. Have been using Field Test (*3001#12345#*) and see that is at -111 or -114. Should normally observe -75 to -85 in this neighborhood. If I go couple blocks towards Kennedy school it improves and near De Anza College it is the best at -68. There is a VZ Cell tower and hence better signal and better data download speeds as well. Very disappointed with VZ, as their support informs that nothing has changed. Hard to believe. Both iPhone 5 and 5s show same symptoms. 4S is slightly better but still horrible data downloads. Verizon needs to seriously look in placing a Tower in the Apple's HQ City and its laughable they make phones but not promise the delivery of service. Huh... .

From 4-7pm calls do not go through. When they do, they are immediately dropped. Extremely poor reception when available. Even the ATT Micro Cell in the house is bad.
