Data
A UK phone roaming in the USA gets expensive fast, and the "£X a day" roaming bundles add up over two weeks. The cheap fix is an eSIM, installed before you leave home.
- Airalo or Saily — US data eSIMs from around £15 for 10–20GB. Buy it, install it while you're still on wi-fi at home, and simply enable it when you land.
- Install it before you fly. Installing an eSIM requires a data connection, which is the thing you don't have at an American airport. People get caught by this constantly.
- Keep your UK SIM active for calls and texts — your bank will send 2FA codes to it — but turn data roaming off on that line specifically. Both can coexist; your phone will use the eSIM for data and the UK line for texts.
- Check your handset is eSIM capable and not network-locked before you buy. Most phones from the last five years are fine.
Budget roughly 1GB per person per day if you're navigating, photographing and mobile-ordering. 20GB comfortably covers a family for two weeks.
In the parks
- Disney has free guest wi-fi park-wide. It's solid near the entrances and main streets, patchy deep in queues and in the middle of Animal Kingdom.
- Universal also has free wi-fi, with weaker coverage.
- Expect to fall back to mobile data exactly when it matters most — mobile ordering lunch from a queue, or checking a wait time before walking fifteen minutes across a park.
This planner's live screens poll every 30–60 seconds, which is nothing on wi-fi and still modest on mobile data.
Battery
The most-ignored tip in Orlando: your phone will die.
GPS running all day, the camera, ten apps polling, and 35°C heat — which itself throttles charging and drains cells faster. A phone that lasts all day at home lasts until about 2pm in a theme park.
- A 20,000mAh power bank covers two phones for a full day. Charge it every night.
- Bring the cables, not just the bank.
- Lower your screen brightness — you'll fight it in direct sun, but auto-brightness at full whack is the biggest single drain.
- Turn off background app refresh for anything you don't need.
- Disney sells FuelRod swap batteries in-park: about $30 for the first one, then free swaps at kiosks forever. Reasonable if you're coming back to Florida; poor value for one trip.
Calling home
- WhatsApp, FaceTime and Messenger over wi-fi — free, and what everyone actually uses.
- Orlando is 5 hours behind the UK. 9am in Florida is 2pm at home; a call after your park day is the middle of the night for them.
- Save the US emergency number: 911.
