Mississippi has a problem and a surprise. The problem: more households here go without any internet subscription than in almost any other state, and in Delta towns like Greenville it is close to one home in five. The surprise: the state now has more fiber passing homes than cable does, because C Spire, the Ridgeland company most people know as a cell carrier, and a crowd of electric cooperatives have been trenching fiber down county roads the cable companies never touched.
Our pick for most Mississippi homes is C Spire. It reaches more of the state than any other non-satellite provider, and where it serves, the product is fiber, the top of our ranking of fiber, then cable, then 5G, then satellite. Widest reach plus best technology is the only basis for the pick. AT&T is the runner-up, as AT&T Fiber in parts of the state and as Internet Air elsewhere.
Which internet providers cover most of Mississippi?
Fiber at broadband speed passes a bit under two-thirds of Mississippi locations, cable about six in ten, and licensed 5G home internet about three-quarters, which is unusually high.[1] Older copper is close to gone.
| Provider | Type | Where it's available | Contract |
|---|---|---|---|
| C Spire | Fiber | Across most of Mississippi | Not stated |
| AT&T | Fiber where built; Internet Air (5G) elsewhere | Across most of Mississippi | No annual contract[2] |
| T-Mobile 5G Home Internet | 5G fixed wireless | Across most of Mississippi | No annual contract[3] |
| Verizon 5G Home Internet | 5G fixed wireless | In many areas | No annual contract[4] |
| Xfinity | Cable | In many areas (Jackson, Hattiesburg, Tupelo, DeSoto County) | No annual contract[5] |
| Sparklight | Cable | In some areas (the Coast) | No contracts[6] |
Block Communications also serves some areas. Starlink, Hughesnet and Viasat reach almost everywhere, and in the Delta they are still the only option on some roads; Viasat's Essentials plan starts at $39.99 a month for a year, then $69.99.[7]
C Spire publishes its prices and terms on its own site and we have not verified them, so ask when you call. AT&T lists 300 Mbps fiber at $50 a month after an autopay discount with no annual contract and no data caps.[2] Xfinity lists 300 Mbps at $45 a month, held five years for new customers on bank autopay and paperless billing.[5] Sparklight is running a 1 Gig promotion at $40 a month for the first year with Auto Pay and paperless billing; its Lift Internet plan is $29.95 for qualifying households.[6]
What is the best internet in Jackson, Gulfport and Southaven?
Jackson is cable-first. Xfinity reaches nearly every address, C Spire almost as many, and AT&T most. But fiber passes fewer than four in ten Jackson homes, so much of what C Spire and AT&T offer in the capital is still wireless. 5G reaches nine in ten Jackson homes, making T-Mobile and AT&T Internet Air the usual rivals to Xfinity.
Gulfport is a fiber city on the edge. Fiber passes about six in ten homes, Sparklight cable reaches every address, and C Spire nearly all of them. Biloxi looks the same: Sparklight everywhere, C Spire nearly everywhere, fiber at a bit under six in ten homes.
Southaven and Olive Branch in DeSoto County are Memphis suburbs with Memphis-grade infrastructure. Fiber passes three-quarters of Southaven and nearly all of Olive Branch, where Brightspeed and Northcentral Electric Cooperative show up alongside Xfinity and C Spire. Hattiesburg is cable-first with Xfinity, C Spire and AT&T present. Tupelo and Madison are fiber towns with C Spire at nearly every home. Greenville is the hard case: almost no fiber, Optimum as the cable company, and 5G covering nearly everyone, which makes T-Mobile a practical first choice there.[8]
Is 5G home internet a good choice in Mississippi?
In Mississippi it is often the best thing you can actually get. 5G home internet at broadband speed reaches about three in four locations, more than fiber or cable.[1] T-Mobile Rely is $50 a month with AutoPay, or $35 with a T-Mobile voice line, unlimited data, no annual contract.[3] Verizon 5G Home is $35 a month with a Verizon mobile plan and has no annual contract or equipment charges.[4] AT&T Internet Air has unlimited data and no annual contract.[2] If C Spire or a co-op has fiber on your road, take the fiber.
What about Mississippi homes with no internet at all?
Roughly one household in eight statewide has no internet subscription, and many more rely on a phone plan alone. Often the line is there and the bill is the obstacle. Sparklight's Lift Internet at $29.95 is open to qualifying households on the Coast.[6] T-Mobile and Verizon drop their 5G prices sharply if someone in the house already has a phone line with them.[3][4] And the electric co-ops building fiber, Northcentral in DeSoto County and Tombigbee around Tupelo among them, sell service without the big-company promo games; check your power bill for the co-op name and ask whether it offers internet.
What should I ask before I sign up?
- Is it fiber or fixed wireless at my address? C Spire and AT&T both sell both.
- What does the plan cost after the promotion? Sparklight's $40 rate is for the first year only.[6]
- Is there a contract? AT&T, T-Mobile, Xfinity and Sparklight say no.[2][3][5][6]
- Is there a data cap? AT&T Fiber and Xfinity say no; Sparklight says unlimited on most plans.[2][5][6]
- Is equipment included, and what does a technician visit cost?
- How soon can they install?
