Never had a problem until the last year or so... now, all calls have week signal (1-2 bars), dropped calls and "can you hear me now" all the time.

The reception seems to have deteriorated over the last year. I get poor reception in and around the neighborhood as well.

I generally cannot receive calls at all. Outgoing calls voice usually works but typically only 1 start. Best case two stars. LTE Never, EVER works. Data usually drops down to 3G, or worse. Siri on an iPhone does not function at all. Email and Text Message take extraordinarily long to deliver (10-30 minutes). Service in Cupertino in general is spotty, but this region Stevens Creek to Bollinger, DeAnza to Blaney seems to be the epicenter of bad.

Need a signal booster (t-mobile 4g lte) to make the phone usable. Generally reception in the bay area is terrible for T-Mobile. Slow data speeds and interrupted calls. Phones are unusable in about 40% of the areas I frequent.

We're a few block south of Steven Creek. Most of the time I only got 1-2 bars of the reception signal inside my house. People on the other end often asked me to repeat what I said. Walking outside of the house is also 2 bars, very rarely up to 3. A few years back, Verizon was better than AT&T; but now, not anymore.
