1 Out of 5 (1 star) | Foothill Blvd. | Chorro St., San Luis Obispo, CA 93405 |

I recently switched to Sprint from AT&T, and so far I have been very dissapoined. Sprints coverage in San luis obispo is terrible. The LTE is spotty, they have no 4G, 3G is slow, and quite often I get 1x around town (1x is the slowest data connection being used today, it's basically 2G) the 1x is too slow to even pull up a YouTube video, or a Wikipedia page. DO NOT SWITCH TO SPRINT. AT&T is much better(I'm sure Verizon is too, I just haven't had it since I've been in SLO.)

Sprint 4G LTE was just finally turned on yesterday. It's just as fast as my home wi-fi. Sprint now has a reliable network.

2 Out of 5 (2 stars) | Santa Rosa St. | Oak St., San Luis Obispo, CA 93405 |

Freshman year (3 years ago) I had T-Mobile and the coverage was perfect. Never dropped calls and the 3 / 4G was blazing fast, especially on / around campus. 2 years ago my family switched to ATT and while the coverage is OK, the speeds are horrible. I have no idea what the other reviews here are talking about. I've done speed tests on smartphones with both carriers and T-Mobile is much, much faster here. I was getting 3-4 Mb / s down on T-Mobile. With ATT I'm lucky to get.7-1Mb / s. Always full bars with T-Mobile around campus. With ATT I've gotten dropped calls, especially in the library. I was especially surprised by this because everyone always gave me crap for having T-Mobile and would ask how bad it was. My 2-year contract is almost up and I'm dying to go back to T-mobile.

I switched to AT&T last year from Verizon and I have had no problems getting reception. I think AT&T has great coverage in this area!

1 Out of 5 (1 star) | Johnson | Tanglewood, San Luis Obispo, CA 93401 |

I made the mistake of switching from T-Mobile to Sprint a little over 2 years ago because they were supposed to have better coverage in SLO and were going to have 4G coverage before any other carrier. As I've come to find out, the coverage is awful, customer service is awful, and Sprint's corporate store here will tell any lie necessary to get a sale. All in all, T-Mobile is a much better choice in this area than Sprint if you want to be able to actually use your phone more than 40% of the time.

Neither I nor any of my friends with Verizon can get reception at my apartment. I either have no G's and no bars or sometimes see 1Y and no bars. Complained about this at the Verizon store in SLO and have also e-mailed. There has been no resolution to my problem

We have been with Boost Mobile (Sprint) since 2004 with Motorola / Nextel (iDEN) phones. We always had poor reception in Los Osos 'cause the towers are in Morro Bay, but signal was great in SLO. Now Sprint is eliminating iDEN service and we just switched to two new LG Reflex (CDMA) phones. NO bars anywhere in Los Osos and one lousy bar around Cal Poly. Boost customer service has hard reset the phones with no joy. I am done with Sprint / Boost.

Have had Verizon since I moved here and have rarely had any problems. Used to have AT&T and it was terrible! Was also able to test out the 4G in New York while I was there on vacation. There is simply no better service here in the San Luis Obispo Area. Everyone I spoke to who has different carriers have had many issues..

Verizon is the Rolls Royce of service providers. I get great signal everywhere. I used to live in Los Osos, and it was perfect there too. Driving to Santa Barbara it is fine the whole way. I had a call drop today though, on 101 by Pismo. My contract us up and I'm changing providers because of the MONEY, so I think that very rare dropped call was a tender mercy.

I just bought a new phone in September. Reception was fine and I never had any problems. Then I went home for winter break and when I came back my phone says "No network" even though it has 5 bars. I know my phone antenna isn't damaged because I can still call the police if I need to. I don't understand what is going on but I really don't like T-Mobile.

I had AT&T when I moved here a year ago. They suck at the central coast. I switched to Verizon. They work great around here but they were expensive. A few months ago I switched to Straighttalk from Walmart. They are 45 bucks unlimited calls.texts and use Verizon towers. It rocks too.

In and around SLO coverage is usually ok, but terrible in the one place I need it most. I'm a Cal Poly student and coverage on-campus is spotty at best. There are very few places on campus that I can send or recieve calls. Coverage gets better when I go into town but it's still not great. Wouldnt recomend T-Mobile if you're going to be spending a lot of time in San Luis.

On all my phones for the last 10 years I've had very good reception from AT&T / Cingluar. I take my phones to all the places people complain about, and I almost always get fine reception.

5 Out of 5 (5 stars) | LOVR | Madonna, San Luis Obispo, CA 93405 |

I haven't been dropped in SLO. (Oddly, my bedroom is the one place I have fewer reception bars.) Traveling north and south is fine too, except one spot between SLO and King City called San Ardo. It only drops for a second if you're on the 101. There's one spot by hills too that sometimes drops. I do that route a lot. Otherwise good. The best place to go if you have problems is the main office on Mill. They're still fake and sneaky and make you wait, but can do more for you there if they mess up. Keep all receipts of any changes you make to your plan.

T-Mobile has worked well for me. They have provided good support for my Sim card based phones from europe. Overall I am very satisfied... .

Got phones in November, still having billing issues with Cingular, they have been overbilling me by hundreds of dollars each month and keep giving me the same old line: "the problem will be fixed by next month". I often do not get phone calls in Santa Maria, and if I am at home I have to go outside to make phone calls.

Absolutely no signal on Tonini but if you cross Los Osos Valley road the signal picks up again. I was told by the CSR to move if I wanted to get a signal at the apartments :-(

The reception here in San Luis Obispo, is good. However, if you head north or south on the 101 the reception starts to drop in and out.

AT&T Wireless (TDMA)

1 Out of 5 (1 star) | SLO, San Luis Obispo, CA 93405 |

As others have said, ATT TDMA does not provides a reliable signal in this region. I left their service Nov. 2003. Signal strength typically read 1 bar except for every now and then when I would notice full strength for half an hour or so. I will never go back to ATT as their CSR's advice was to try to use my phone when it did read full strength rather than some promise to fix the problem or being told the problem was not repairable. I am confident their support knows nothing of what is going on and after complaining mutliple times along with the other ATT users in SLO I was told that no one else was reporting the problem.
