AT&T

5 Out of 5 (5 stars) | 1 Grand Ave. | Cal Ply, San Luis Obispo, CA 93410 |

LTE is available 95% of the time, and HSPA+ (4G) is there when it isn't. The only time I have lost reception is when I hiked VERY deep into Poly Canyon. Would highly recommend. I know not all LTE radios (and GSM radios) are created equal. To be fair, I do own an iPhone 6 which is the latest model at the time of this review, so others with older devices may not be experiencing the same results.

Compared Verizon (have now) and T-Mobile (have now, waiting for end of contract). T-Mobile, 4 bars, Verizon 2 bars. T mobile much, much better and much more reasonable (price AND no contract).

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..
