Other Support Requests: For anything else, head to our contact page.
Of course. You can install your United Kingdom eSIM up to 30 days before departure. Once you arrive, it will activate automatically.
Installing early won’t use any data or start your plan until you arrive in United Kingdom.
If your iPhone shows an activation error during pre-install, you can ignore often it — refer to our eSIM Troubleshooting Guide for help.
Your United Kingdom travel eSIM kicks in as soon as you arrive in United Kingdom — provided it was installed beforehand.
If you install it after you land, it should start working right away.
If you run into trouble, see our eSIM Troubleshooting Guide or get in touch with us.
If you want to avoid roaming headaches in United Kingdom, a travel eSIM is the smarter pick:
Big Savings: Our local United Kingdom eSIM data plans are priced for residents, not tourists who pay premium roaming costs.
Easy Plan Changes: Upgrade or downgrade your data allowance on the fly - no need for a new SIM.
Full Transparency: See your data usage in - app so you won’t run out unexpectedly or incur extra charges.
No — the plan’s data and days only start when you arrive in United Kingdom. Installation beforehand simply sets it up for activation on landing.
We recommend installing before departure since you will need WiFi to complete the installation process and this way you will be connected as soon as you land.
If you need help connecting, check our eSIM Troubleshooting Guide or reach out to us.
No - our United Kingdom travel eSIMs are data - only, so they don’t come with a voice line or phone number. Any calls or texts must go through internet apps like WhatsApp, Telegram, or Viber.
These eSIMs don’t include voice minutes - data only. For any calling or texting, you’ll need to rely on VoIP or messaging apps such as WhatsApp, Viber, or Messenger.
Absolutely! ZenSim’s eSIMs work in over 200 countries, and United Kingdom is one of them. We also have regional eSIMs that cover several nations on a single plan - check out our Travel eSIMs page for details.
Your United Kingdom eSIM is designed for use within United Kingdom, so once it's been activated there, it won’t work in other countries.
If you're visiting multiple destinations, a better option might be one of our regional Travel eSIMs that cover entire regions like Europe or Asia.
Your eSIM will activate automatically when you arrive in United Kingdom. We recommend installing your United Kingdom Travel eSIM in advance (installation is different from activation).
Just scan the QR code you receive or install via the ZenSim app using WiFi. Once you touch down in United Kingdom, your eSIM will go live automatically.
