United Kingdom eSIM FAQs
No, your plan only starts upon landing in United Kingdom. Installing beforehand ensures you’re ready to go as the activation will happen automatically.
You’ll need WiFi for installation, so do it before departure and this way you will be connected as soon as you arrive.
If you run into any issues, our eSIM Troubleshooting Guide can help, or contact us directly.
No, the United Kingdom eSIM is data - only and excludes voice/SMS numbers. You’ll have to rely on data - based messaging platforms like WhatsApp or Telegram for calling.
Network & Data Issues: If your eSIM is refusing to work, check out our eSIM troubleshooting guide. For personalized help, send us a message and we’ll jump on it.
Installation Queries: Need a walkthrough on how to install? View our eSIM install tutorial - or drop us a line via our contact form.
General Support: Have something else in mind? Reach out here and we’ll handle it swiftly.
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.
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.
Your United Kingdom eSIM will start working the moment you land in United Kingdom-it auto-activates if installed prior to departure.
If you install it after arrival, it will connect immediately.
Trouble connecting? Visit our eSIM Troubleshooting Guide or contact us for help.
Our United Kingdom travel eSIMs are purely data - no native voice or SMS services are included. If you need calling, use an internet - based app like WhatsApp or Skype over your data connection.
Yes, you can. Around 99 percent of our eSIMs allow quick and easy top ups through the ZenSim app. You can add more data, increase the days, or even include a different destination on the same eSIM right from the Zen Garden.
Open the app, go to the Zen Garden area, and you’ll see the top up button waiting for you.
Travelling for a while: If your trip lasts more than 30 days, you can queue multiple top ups. None of them will interrupt your current plan because each one only activates when the previous eSIM expires.
Travelling to more destinations: Most eSIMs let you attach extra countries via a top up. For example, if you're heading home from Europe and stopping in Singapore, you can add Singapore to your Europe eSIM and it will switch on once you arrive.
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.
