eSIM Support & FAQ

An eSIM (embedded SIM) is a digital SIM built into your phone. Instead of inserting a physical SIM card, you install an eSIM data plan by scanning a QR code. With an eSIM888 travel eSIM you get mobile data abroad without swapping SIM cards or paying expensive roaming fees.

Your phone must support eSIM and be carrier unlocked. On iPhone, go to Settings > General > About and look for a "Digital SIM" or "Available SIM" entry. On Android, go to Settings > Network & internet > SIMs and check for an option to add or download an eSIM. You can also dial *#06# — if an EID number is shown, your phone supports eSIM. See the "eSIM Supported Phones list" above for details.

The eSIM QR code is emailed to you immediately after you complete your order. If you are a member, you can also find your eSIM under "My eSIM" after logging in.

We recommend installing your eSIM as soon as you receive the QR code, or a few days before your trip. Installation requires an internet connection (Wi-Fi is fine). Installing early does not use up your plan — the validity period only starts when you arrive at your destination.

Your data usage period begins only when your eSIM is activated at your destination — that is, when it first connects to a supported network listed under "Internet service provider" on the product page. You have up to 180 days from the purchase date to activate your eSIM.

The APN (Access Point Name) for each country is shown at the top of its product page. Make sure the APN in your eSIM settings matches it — an incorrect APN is the most common reason for having signal but no internet.

First, make sure the eSIM line is turned on, selected for cellular/mobile data, and that data roaming is enabled for the eSIM. Check that the APN is set correctly. Then turn Airplane mode on, wait a few seconds, and turn it off again so your phone reconnects to the network. If it still does not work, contact our support team.

Daily Pass plans give you a fixed amount of high-speed data each day, where one day is counted as 24 hours. Once you reach the daily limit, your speed is reduced to 128 kbps. Your full speed and data allowance reset automatically at the start of the next day.

It depends on the plan. Each product page shows whether hotspot (tethering) is supported for that country.

If the plan supports top-up (shown as "Top-up option" on the product page), members can add more data to the same eSIM from "My eSIM" after logging in, without installing a new QR code. See "Member vs. Non-Member" and "eSIM add-on and reusing old services" above for details.

No. No matter what your phone shows, please do not delete your eSIM — once deleted it cannot be installed or used again. If you run into any problem during installation or use, contact our customer service first.

Most eSIM-compatible phones support dual SIM, so you can keep your home SIM installed for calls and SMS while using the eSIM for mobile data. To avoid unexpected roaming charges, turn off data roaming on your home SIM while traveling.
