Our verdict: an easy way to avoid roaming charges, with cheap data eSIMs for 200+ countries that you set up before you fly.
What we like
- Travel eSIMs for 200+ countries
- Cheap data: 10GB from about £5 in Turkey and Singapore
- One-off payment, typically valid 30 days
- Data-only, so you keep your UK number on your main SIM
- Unlimited day passes in many countries
Things to know
- Data-only eSIMs don't give you a local phone number
- Prices vary a lot by country (the Maldives is expensive)
- Needs an unlocked, eSIM-compatible phone
Prices
WorldSIM's data eSIMs start from a few pounds. Examples from our checks: Turkey 10GB £5.04, Singapore 10GB £5.04, Thailand 10GB £7.06, Japan 10GB £7.78 and USA 10GB £10.08, each valid for 30 days. Unlimited plans for 7 days are also available in many countries.
Versus roaming
Our UK Roaming Cost Report found a week of roaming costs £30–£56 on Vodafone, EE and O2 in most long-haul destinations. A WorldSIM eSIM covering the whole trip usually costs a fraction of that.
How it works
Buy the eSIM, scan the QR code at home on Wi-Fi, then switch it on when you land. Keep your UK SIM active for calls and texts.
