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.
Mobile networks in the UK: what Indian travellers need to know
The UK's main carriers are EE, O2, Vodafone, and Three (3). HelloRoam connects on O2, 3, and Vodafone. O2 has strong urban coverage and wide 5G deployment. Vodafone covers major cities and business districts. Three has competitive 5G in metropolitan areas. Your eSIM automatically selects the best signal available.

HelloRoam eSIM vs Airtel UK roaming vs UK local SIM
A practical cost comparison for Indian travellers visiting the United Kingdom.
| Category | HelloRoam eSIM Recommended | UK local SIM (O2, Vodafone, or Three) | Airtel/Jio UK international roaming |
|---|---|---|---|
| Typical cost | From ₹475.87 total | ₹951.75–₹2,379.37 total | ₹761.40–₹1,142.10/day |
| Details | Plans start at ₹270.30. Buy before you fly from India, scan the QR code at home, and arrive at Heathrow or Gatwick already connected. No airport SIM queues, no setup hassle. | Tourist SIMs from O2, Vodafone, or Three are available at UK airports and supermarkets. They require physical purchase after you land and often come with unused credit that expires. A HelloRoam eSIM is set up before you board in India. | Airtel and Jio UK international roaming packs can cost much more than a HelloRoam eSIM for the same trip length. A 7 to 10 day roaming pack from Indian carriers often runs to several times the cost of a HelloRoam plan. HelloRoam plans are far better value for money. |

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
