eSIM Travel Tips for London
OE in London: A HelloRoam eSIM Bridges the Gap
Most Kiwis on OE buy a local UK SIM within a few days of arriving. A HelloRoam eSIM keeps you connected from the moment you clear Heathrow arrivals. Use it while sorting out your UK bank account, National Insurance number, and local phone contract. It's a practical bridge for the first week or two.
Set Up a Contactless Payment Method Before the Tube
The London Underground and all buses accept contactless card payment. No Oyster card needed if you have a Visa or Mastercard. Google Pay and Apple Pay both work. With your HelloRoam eSIM active, you can top up a digital wallet or manage your bank apps from the arrivals hall at Heathrow.
Tube Signal Has Gaps on Older Lines
4G is available at all underground stations in central London. However, between stations in the tunnels of older lines (Bakerloo, Central, District), signal drops. Download your route and offline maps before entering any tunnel section. The Elizabeth line has the most consistent in-tunnel coverage.
Download the Citymapper App Before You Arrive
Citymapper is the best navigation app for London public transport. It works with your HelloRoam eSIM and shows Tube, bus, Overground, and Elizabeth line options in real time. Download the app and the offline London map before landing at Heathrow or Gatwick.
Know the Emergency Number
The UK emergency number is 999 for police, ambulance, and fire. The non-emergency police line is 101. Save these before attending large events, walking late at night, or taking night buses. Emergency calls work on any active eSIM in the UK.
Best Time to Visit London
New Zealand travellers planning a trip to London should consider May–September as the most rewarding time to visit. Temperatures around 2°C to 24°C make exploring comfortable. July is the busiest month with highest fares from New Zealand. November–March is quieter. Wimbledon (June–July) is a local highlight. Avoid January–February if possible. Your HelloRoam eSIM keeps you online all year.

What Kiwi Travellers Say

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.
