Coverage and network

Coverage from the parks to the Keys

United States mobile networks

Two things shape Florida coverage. The theme-park corridor around Orlando has infrastructure sized for tens of thousands of daily visitors, so it holds up on the busiest days. Then there is the Overseas Highway and the Everglades, where the geography does the deciding. (Speedtest by Ookla, June 2026)

Where it holds and where it drops

  • Orlando and the parks: Strong inside the resorts and across the park estates. Queue and ride-booking apps work on peak days, which is the real test.
  • Miami and Fort Lauderdale: Dense coverage across both, including South Beach and the Brickell towers.
  • The Overseas Highway to Key West: Coverage runs most of the 113 miles, with short drops on the longer bridges between islands. Nothing you would notice unless you were mid-call.
  • The Everglades: Limited to absent once you are off the Tamiami Trail. Airboat tours and the back country have nothing.

Panhandle to Key West

One nationwide plan, so a Florida trip that adds New York or a cruise departure elsewhere is already covered.

Frequently asked questions

Coverage

Where to buy a SIM card in Florida?

Miami and Orlando airports both have carrier kiosks, priced above retail. A Walmart or Target in town is cheaper. An eSIM avoids the errand.

Does a prepaid SIM need ID in Florida?

No - it is a federal matter and there is no requirement anywhere in the US. A card off a Publix or Walgreens shelf needs only payment, and an eSIM needs no check at all.

Will it work in the theme parks and down in the Keys?

The parks, yes - they are built for crowd-scale data and the ride-booking apps work even at capacity. The Keys are covered along most of the Overseas Highway, with brief drops on the long bridges. The Everglades are the genuine gap: little to nothing away from the main road.

Troubleshooting

eSIM not working in Florida?

Check the Ohayu eSIM is your selected data line and roaming is on for it, then toggle Airplane mode once. In the Everglades or mid-bridge in the Keys there may simply be no coverage. Chat and support@ohayu.com run 24/7.
