Questions before boarding

Will my phone work with an eSIM?
Most phones from 2019 onward support eSIM — iPhone XS and newer, Pixel 3+, Galaxy S20+. Dial *#06# and look for an EID to confirm.
How do I install my eSIM?
After you order you get a QR code. Scan it in your phone's settings to add the eSIM; you need an internet connection, such as Wi-Fi, for that. Each plan is valid for the number of days shown on it.
Can I keep WhatsApp and my number?
Yes. Your physical SIM stays in place for calls and texts; esimrails handles data, so WhatsApp and iMessage keep your number.
What if I run out of data?
Top up in one tap from your account — no new QR code, no reinstall.
United Kingdom: how much does an eSIM cost?
Plans start at $2.99 and go up to $120.99, depending on the data and the number of days. The lowest price per GB is $1.21.
United Kingdom: how much data and how many days can I get?
Data options: 1 GB, 2 GB, 3 GB, 5 GB, 10 GB, 20 GB, 50 GB, and 100 GB. Unlimited plans are also available. Plan lengths: 7 days, 10 days, 15 days, and 30 days. Unlimited plans are fair use: after a high-speed data allowance, which depends on the plan, your speed may be reduced.
United Kingdom: which networks do the eSIM plans use?
Networks listed on the plans: O2 UK, Three UK, and Vodafone UK. What you connect to depends on the network and on where you are.
United Kingdom: can I use 5G with an eSIM?
Every plan lists 5G. You need a 5G-capable phone and 5G coverage where you are; otherwise your phone uses a slower connection.
