Worst customer service I've ever experienced in my entire life, which is especially wonderful when dropped calls, inexplicable data drainage, and texting delays are standard and to be expected. What am I paying for again???

Went there to buy phone,and these jerks added a home phone service on my plan,i tried to return phone and they charged me 35$ restocking fee plus 35$ fee on the hm phone service..well these jerks told me that the refund that was suppose to be returned to me on my card cannot be accepted for restock fee,so I had to pay out of pocket,and with all said and dont I could not even return the phone.anyone who goes with Sprint better rethink there network sucks,there are alot better ones out there.ALSO TO ADD<<<< THERE CUSTOMER SERVICE FROM A SCALE OF 0 TO 10 I WOULD RATE THEM A 0 BECAUSE CUSTOMERS ALWAYS COMES FIRST NOT THEM.

I have had Sprint for 14 years with no problems, but suddenly this summer cannot use the phone on the first floor of my house and almost never get 5 bar reception in San Francisco. What has happened? Did they lose a tower?

I've had Sprint for 16 years. Reception has been excellent until the last 6 months or so. Now, service is horrible. I keep getting dropped calls and call failures and calls that won't even connect. I've called Sprint on this 5 times in the last 3 months. It's like everyone has said, they're working on upgrading the towers. It's frustrating. The tower I use is only 2 blocks away at Fell and Laguna. They, why is service so bad?

I have lost job interviews due to not having any cell reception at all. Not even bad, because that would give the perception that you can send texts or a call. Once I leave my area I am bombarding with 10 new messages / missed calls. I went to the store, they knowingly tell me service is bad yet they charge me the same amount where others actually can use there services. I will be switching to Verizon due to their lack of coverage and the lack of ability to facilitate the issue - I.E. "you can buy a microcell for 200" ARE YOU KIDDING ME?! how about you give me the microcell as I have been a customer for 10 years and dishing out cash to you. But no, "we cant do that, even though you pay for a service we cant provide" Overall HORRIBLE experience

Poorest reception in this area results in continually dropped calls, inability to initiate a call. Constant roaming results in drained charge within three (3) hours; requires phone to be connected to charger while at work.

Cannot send or receive calls, cannot send or receive text messages. Phone will show one or two bars and "3G " or Edge (the little circle. This has already placed me in a difficult situation, cannot imagine if it was an emergency. FYI... AT&T cellular signal works perfectly... go figure.

1 Out of 5 (1 star) | Church St. | 24th St., San Francisco, CA 94114 |

3G data reception around Church and 30th as well as Church and 24th has been terrible for years. Underground in BART 3G reception is good between 16th and Mission and Glen Park. Along the Market St.corridor, however, 3G can be nonexistent if there are any crowds at all at the stations and in the trains; often I lose 3G entirely there. Call Sprint to talk about this and they say they're working on fixing it. They have been saying that for years. I'm done with them.

I have found Sprint to be the most reliable but not the fastest network. I have had both ATT and Verizon and have to be at the front of the building to make a call but Sprint works no problem throughout with 3 bars. Sprint Lacks good LTE coverage everywhere.

I dma Google maps e from SFO to Ukiah and had very little reception the whole time. My Google maps had a lot of trouble. I could not send texts or make calls at all for much of the way.

The coverage in San Francisco is great with a few exceptions. Inside buildings with thick or concrete walls, reception greatly diminishes. The city is mostly covered with LTE and you do fall back on 4G HSPA+ which is still speedy fast.

Sprint has the worst coverage, and the worst customer service to deal with the fact that their network is sub-par. Sold as a competitor to other networks, I was deceived and wound up in a two year contract of poor service. I would not recommend Sprint to anyone.

Walking around the Lower Haight the signal is mostly weak; unable to update weather; cannot use GPS, No Data; calls are constantly dropped. I also live in the Lower Haight and I used to receive a strong signal in my apartment, now I barely have a signal. Since my contract is over I'm switching carriers. Bye Bye sprint.

I was with Sprint since late 90s, and their voice and data service has dropped to terrible in last two years. Sprint no longer provides dependable mobile phone services for San Francisco Market! The only thing dependable about Sprint that you can count on is having continuous dropped calls and non working GPS if using your phone while driving in and out of City. What's worse is that Sprint customer service, field service and Executive Office escalations will tell you they apologize, they'll research and then do nothing. If they call or email back, they have no remedy to offer... they just recite the same empty script. Sprint makes Smartphones Dumb!

Voice reception and data are horrible. 4 bars on 3G Or 4G means nothing as voice calls are dropped constantly or very choppy. Apps such as Facebook and Instagram or visibly slower than both AT&T and Verizon when compared side by side. At least twice as slow. Unlimited data means nothing with horrible reception. I'd rather have limited data that is much more reliable. I can't wait to till my contract is over! DO NOT USE SPRINT FOR YOU MOBILE PHONE SERVICE.

I do have a pretty good reception throughout the city with the exception of the Laurel heights area as well as the Delores Park area. The data speeds however. Even with full bars is slow as hell. Unusable for streaming. 4G has been slower than 3G once was. 3G speeds, ridiculous. Mps =.0 something.
