Yes, EE works in Japan. EE’s Roam Abroad add-on charges £5 per day for talk, text, and your home plan’s data on SoftBank’s network. A typical 10-day Japan trip — Tokyo, Kyoto, Osaka — costs £50 with Roam Abroad. The same trip with an eSIM costs around £6.60. Honest math + when EE roaming is the right call below.
Travelren is an independent eSIM brand. We sell Japan plans, so this comparison has stakes. Here’s the honest comparison for UK travellers.
The quick answer
- EE Roam Abroad in Japan: £5/day, unlimited calls + texts + your home plan data, only on usage days. Routes on SoftBank.
- Travelren eSIM, 3GB / 30 days for Japan: approximately £6.60
- Crossover: the eSIM is cheaper for any trip 2+ days.
How EE actually works when you land in Japan
Japan has three main carriers: NTT Docomo, SoftBank, and KDDI au. EE’s roaming partners route to SoftBank. Coverage is excellent across Tokyo, Osaka, Kyoto, Hiroshima, Fukuoka. 5G in city centres typically pulls 100+ Mbps; 4G LTE everywhere else, including the shinkansen between cities.
Roam Abroad activates automatically on first use. EE sends an SMS confirming. Days you don’t use the network aren’t billed — but background syncs count as usage. Disable cellular data on landing if you want some quiet days.

Common questions
Can I buy a SIM at Narita / Haneda?
You can — but Japanese tourist SIMs are notoriously expensive (JPY 4,000-8,000 / £20-45 for 7-15 days) and the kiosks queue badly. The eSIM at £6.60 is much cheaper.
What about pocket WiFi?
Pocket WiFi rental at the airport is £30-60 for a week and gets you the same SoftBank coverage as your phone would have on an eSIM. The eSIM is the same product without the extra device.
Will iMessage and WhatsApp keep working?
Yes. Both tied to your Apple ID / phone number registration. Work on any data connection.
How do I top up Suica without a Japanese phone number?
Apple Wallet’s Suica works on any iPhone with eSIM data — doesn’t require a Japanese phone number. Top up via Apple Pay using your UK card.
The bottom line
For any Japan trip 2+ days, an eSIM beats EE Roam Abroad on price. A 10-day Japan trip: £6.60 with Travelren versus £50 with Roam Abroad — £43.40 saved.
