eSIM Travel Tips for UK
Activate before your overnight flight
Most Canadians fly to London on overnight transatlantic flights from Toronto, Vancouver, or Montreal. Set up your HelloRoam eSIM at home the evening before departure. You step off the plane at Heathrow or Gatwick already online for the Tube map and hotel directions.
Download the London Underground map offline
The Tube has Wi-Fi at many stations but not in tunnels. Download your TfL Oyster card app and offline tube maps before you arrive. Your HelloRoam eSIM gives you data above ground for Google Maps and above-ground bus routes across Greater London.
Coverage across Scotland and Wales is good in cities
Edinburgh, Glasgow, and Cardiff have strong 4G and 5G coverage. Rural areas of the Scottish Highlands and parts of Wales have limited signal from any carrier. Download offline maps before driving on single-track roads in the Highlands or coastal Wales.
Keep your Canadian SIM for family calls
On a dual SIM phone, keep your Canadian SIM active. Family can reach you on your regular number. Use your HelloRoam data connection for WhatsApp or FaceTime calls at no extra cost, which is usually clearer than calling internationally anyway.
The UK uses British spellings and some different apps
City Mapper and Google Maps both work well in UK cities with a good data connection. Uber operates in London and major cities. Download the free Citymapper app for the best transit directions in London, Manchester, and Edinburgh.
