The start of validity depends on the package. Installation, activation and first network connection can be different triggers. Read the selected plan and order instructions before installing or enabling your eSIM; contact support if the trigger is unclear.

You can install ahead of travel only when the package instructions allow it. Check whether installation starts validity and whether there is an activation deadline. Use a stable internet connection and follow the instructions for your order.

Check the exact model, country variant and carrier-unlock status. Support for eSIM on a device does not guarantee support for every travel plan. Use the compatibility checker and manufacturer specifications before buying.

On a compatible Dual SIM device, you can keep your home SIM and use the travel eSIM for data. Select the correct data line and check automatic switching. Calls, texts and roaming on your home SIM can still incur charges.

Top-up is available only for supported eSIMs and eligible offers. Check your order options or ask Corelinx support. A separate new plan may require a new eSIM installation; do not assume every purchase adds data to the existing profile.
