eSIM Travel Tips for London
London is the top destination for South Africans in Europe
London has the largest South African community in Europe. South African Airways, British Airways, and Virgin Atlantic fly direct from OR Tambo to Heathrow. Buy your HelloRoam UK eSIM before you leave Johannesburg. One plan covers London and the rest of the UK so you are sorted from the moment you land.
The Elizabeth line is the best-connected Tube route
The Elizabeth line runs from Heathrow Airport through central London to Shenfield and Abbey Wood with 4G throughout all tunnels. This makes it far better connected than older deep Tube lines. Take it directly from Heathrow into the city with data running the whole way.
Keep your South African number active for WhatsApp
On a dual-SIM phone, keep your Vodacom, MTN, or Cell C SIM active for WhatsApp messages from family back home. Set HelloRoam as your data line. You stay reachable on your South African number while your UK data costs stay under control.
Check the exchange rate before you budget
The rand weakens against the pound, so budget carefully. A HelloRoam UK eSIM plan in USD converts to a fraction of what Vodacom or MTN international roaming costs. Use the XE Currency app, which runs well on your HelloRoam data.
Download the TfL app and Citymapper before your flight
Transport for London's app and Citymapper both need a live data connection for real-time journey planning. Download and log in before you fly. Your HelloRoam eSIM gives you data from the Heathrow arrivals hall so both apps work immediately.
Mobile networks in London: EE and Vodafone UK
London is served primarily by EE and Vodafone UK on 5G networks. EE runs London's most extensive 5G network across all Inner London boroughs and most of Outer London. Vodafone UK provides strong parallel 5G in the West End, Mayfair, and Canary Wharf. Your HelloRoam eSIM connects to EE and Vodafone UK for the broadest London coverage.

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.
