eSIM Travel Tips for UK
Install your eSIM before your India-UK flight
A direct flight from Mumbai or Delhi to London takes around 9 to 10 hours. Set up your HelloRoam eSIM at home before you leave. Enable data when you land at Heathrow Terminal 2, 3, 4, or 5 and you are instantly online for Uber, TfL, and Google Maps.
Use the Tube app without worrying about Wi-Fi gaps
Transport for London (TfL) apps and Citymapper work well with mobile data above ground. Some Underground stations now have 4G coverage on certain lines. Having your own data via a HelloRoam eSIM means you are not dependent on patchy Underground Wi-Fi.
Keep your Indian SIM for OTP and bank messages
Indian banks, UPI apps, and IRCTC send OTPs to your Indian number. Keep your Jio or Airtel SIM active in slot 2. Use your HelloRoam eSIM for data. Both can run simultaneously on a dual SIM phone.
Rural UK can have limited 5G
Scotland's Highlands, rural Wales, and parts of northern England have more limited mobile coverage. If you are visiting the Lake District or Scottish Highlands, download offline maps in advance. 4G is available in most towns but 5G is mainly urban.
Track data usage carefully
The UK is an expensive country and streaming or video calling back to India can consume data quickly. The HelloRoam app sends alerts at 80% and 95% so you can top up before running out.
