We recommend installing your eSIM before your trip while connected to stable Wi-Fi.
Make sure to install it within the Installation Window shown in your Package Details.
For some destinations, local restrictions may require you to install the eSIM before arrival. For example, eSIMs for Turkey must be installed before entering the country.
The Installation Window is the period after purchase during which you can install your eSIM.
Make sure to install your eSIM before the Installation Window ends.
You can check the remaining Installation Window in your Package Details.
The Activation Trigger tells you when your eSIM plan begins.
Depending on the plan, the plan may start when the eSIM is installed or when it first connects to a supported local network.
Check the Activation Trigger in your Package Details for the exact rule for your plan.
The Validity Period is how long your eSIM plan remains available after the Activation Trigger occurs.
For example, if your Package Details shows a Validity Period of 1 day, you will have 1 day of internet usage after the plan starts.
You can install your eSIM using either of these methods:

Your eSIM purchase email includes:
You can scan the QR Code or enter the activation details manually.
Each eSIM can only be installed once. Do not share your QR Code or activation details with anyone.
This eSIM provides mobile data only.
It does not support calls or text messages through your phone’s native Phone or Messages apps.
You can still make calls and send texts through MySecondLine using your data connection.
Data Allowance shows the amount of data included with your plan.
For Regular Data Packages, this is the amount of data available before the package is used up or the connection becomes limited according to the plan.
For Unlimited Packages, Package Details may show how much high-speed data is included before the speed is reduced.
Data usage shows how much data you have used from your current eSIM plan.
For plans with a high-speed allowance, you may also see how much high-speed data has been used.
Regular Data Packages
You receive a fixed amount of data.
Once your Data Allowance is used up, your connection may stop or become extremely slow, depending on the plan.
Unlimited Packages
There is no fixed total data limit, so you can continue using mobile data.
Some Unlimited plans include a high-speed allowance. After that allowance is used, your speed may be reduced.
Check the Data Allowance section in Package Details for the exact rule for your plan.
FUP Unlimited
You receive high-speed data up to a specified amount. After that, you can continue using unlimited data at a reduced speed.
Non-FUP Unlimited
You can continue using high-speed data without usage-based speed reduction.
It depends on your plan.
Regular Data Package
Your connection may stop or become extremely slow once your Data Allowance is used up.
FUP Unlimited
Your speed will be reduced after the high-speed allowance is used, but you can continue using data.
Non-FUP Unlimited
You can continue using data at high speed without usage-based throttling.
Check your Package Details for the exact Data Allowance and speed rule.

Your device must support eSIM to install the plan.
If you are not sure whether your device supports eSIM, check your device compatibility before completing the installation.
