Every answer before takeoff
Everything you need to choose, install and use your travel eSIM with confidence.
What is an eSIM?+
An eSIM is a digital SIM built into compatible devices. It lets you add a data plan without inserting a physical SIM card.
How can I check whether my phone is compatible?+
Use our Device compatibility page and make sure the phone is unlocked. You can also dial *#06#: an EID generally indicates eSIM support.
Can I keep my usual SIM and phone number?+
Yes. Most dual-SIM phones let you keep your main line for calls and messages while using the eSIM for travel data.
When should I install my eSIM?+
Install it before departure using a stable Wi-Fi connection. Enable its mobile data only after arriving in the covered area, unless the plan says otherwise.
How do I install the QR code?+
Open your mobile data settings, choose Add eSIM, scan the QR code displayed on another screen and follow the instructions.
Can I scan the QR code more than once?+
Usually not. Most eSIM QR codes are designed for one installation. Do not delete an installed eSIM without contacting support.
Why does my eSIM have no internet?+
Check that the eSIM line is enabled, selected for mobile data and that data roaming is enabled for this line. Restart the phone and check the APN provided by email.
Can I share data with a hotspot?+
Hotspot availability depends on the plan and local network. Check the product description before purchase.
How can I check my remaining data?+
Use the balance or usage link supplied with the order when available. Your phone’s data statistics also provide an estimate.
When will I receive my eSIM?+
The QR code and instructions are normally emailed shortly after payment confirmation. Check your spam folder and the email address used during payment.
Can I cancel or receive a refund?+
Eligibility depends on delivery, installation and use of the eSIM. Read the refund policy and contact us with your order number.
What information should I send to support?+
Send your order number, phone model, destination and screenshots of the eSIM settings. Never send a password or full bank card details.
