Charleston, SC

U-wifi Home Unlimited is $55 a month anywhere we're live in Charleston, whether you're in Daniel Island, West Ashley or out by French Quarter. The next-gen gateway, two-day shipping and your first 30 days are free, and there's no contract. Or pay nothing at all with FreeU: watch ads you choose in the U-wifi app and earn credit toward your bill.

Every U-wifi customer in Charleston can switch on FreeU inside the U-wifi app. Our Choice Advertising model lets you pick the ads you see, and watching them earns credit against your monthly service. Watch enough and the $55 is covered. Keep watching past that and you earn U-Bonus points toward merchandise in the U-store. Same gateway, same unlimited data, same speeds.

Wired speeds in Charleston vary widely by street and neighborhood, with some blocks getting gigabit fiber and others stuck on old cable. Tower signal strength changes based on where you are relative to the water and how dense the buildings are around you. U-wifi doesn't tie you to one network. Our gateway picks the strongest 5G signal at your address across the major national carriers and switches if a better one appears, so you get the best speed available in your part of Charleston at any given hour. For the best signal, put the gateway near a window on the highest floor, facing the nearest tower.

Charleston sits on the Atlantic coast and faces hurricane season and coastal flooding every year. Because U-wifi runs on multiple carrier networks instead of a single cable line, if one tower goes down your gateway shifts to the next available one. During a major storm, service depends on carrier tower power and whether the networks stay up, but you're not waiting on a single provider to send a truck after the water recedes.

Yes. Apartments are common around Daniel Island and West Ashley, where a plug-in gateway means no landlord approval and no holes in the walls. The gateway plugs into any outlet and works best near a window. No drilling, no antennas on the roof and nothing to remove when you move out. The gateway's wifi covers a typical 2,500 square foot home and supports up to 256 devices, so a one-bedroom or a shared house is fine.

Enter your Charleston address to confirm coverage, order, and the gateway arrives within two days. Plug it in, find the U-wifi network on your phone or laptop, and enter the password printed on the bottom of the gateway. That's the whole install. No technician, no appointment window, and your first 30 days are a free trial.

Pack the gateway, plug it in at the new address and connect as usual. Then sign in to your U-wifi account and update your address. Nothing to return, nothing to reschedule, and the price stays the same.

U-wifi is live across Charleston and in Mount Pleasant, North Charleston and Goose Creek. Enter your address to confirm availability at your home. If you're on the edge of coverage, the gateway also supports an external antenna for weaker 5G areas.
