eSIM Travel Tips for UK
London is a top destination for Singaporeans: sort your eSIM at home
Singapore to London Heathrow is about 13 hours on Singapore Airlines. Set up your HelloRoam eSIM the night before your Changi departure. Enable data when you land at Heathrow and the TfL (Transport for London) app, Citymapper, and Uber work immediately. No SIM hunting at Heathrow needed.
TfL, Elizabeth line, and the Tube need live data
London's public transport network is vast. The Citymapper and TfL Go apps are the best ways to navigate the Underground, the Elizabeth line, and London buses. Both need live data. Your HelloRoam eSIM keeps transit apps running from Heathrow Terminal 2 or 5 all the way into Central London.
Shopping in London: from Harrods to Oxford Street
London shopping is a major draw for Singapore visitors. Harrods, Selfridges, Oxford Street, and the King's Road are all well covered with 5G. Your HelloRoam eSIM keeps Google Maps, online banking, and price comparison apps running throughout your London shopping days.
Edinburgh and Scotland: good coverage in cities, limited in Highlands
Edinburgh's Old Town, the Royal Mile, and Arthur's Seat area have excellent 4G and 5G. The Scottish Highlands (Glencoe, Ben Nevis, Isle of Skye) have very limited signal. Download offline maps of the Highlands and your road trip itinerary before leaving Edinburgh.
Many Singaporeans have family in the UK: plan your data
The Singapore community in the UK is significant. Whether visiting family in London, Manchester, or Birmingham, or attending university open days, a HelloRoam eSIM keeps WhatsApp, video calls back to Singapore, and navigation all running throughout your UK stay.
Mobile networks in the UK: what Singapore visitors need to know
HelloRoam connects on EE and Three in the United Kingdom. Both are major national operators with 5G in London and major cities and 4G across England, Scotland, and Wales. Rural Scotland and remote areas of Wales and northern England can have limited signal.

| Typical cost | From SGD 3.65 total | SGD 12.85–SGD 32.12 total | — |
| Details | Plans from S$3.65. Buy before your SIA or BA flight from Changi, activate at home, and land at Heathrow already on local EE 5G or Three 4G. TfL journey planning ready from the terminal. | UK prepaid SIMs are available at airport shops. But after a 13-hour flight from Changi, a HelloRoam eSIM already activated at home is far more convenient. | Roaming packages from Singapore carriers can get expensive in the UK. Two weeks in London and Edinburgh on SG roaming adds up very significantly compared to a HelloRoam eSIM. |

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.
