When should you install your travel eSIM?

Check what starts your plan's validity

Buying a plan, installing an eSIM and connecting to a mobile network can happen at different times. Installation adds the eSIM to your phone. Your plan's activation rule determines when its days begin.

Read the plan details and setup instructions before scanning the QR code. Look for the event that starts validity, plus any deadline for installing or activating the plan.

A regional or global plan may cover your home country or a stopover. If connection starts validity, turning the line on there could start the plan before you reach your final destination. Check every country on your route.

Turning a line off is a phone setting. Don't assume it pauses a validity period that has already begun.

Get ready while you still have reliable Wi-Fi

Once you've confirmed that early installation suits your plan, choose a quiet moment before departure. You can read the instructions properly and deal with a setup question before you're looking for your airport transfer.

Check your exact phone model and whether it's unlocked before buying. On an iPhone, open Settings, General, then About. The Carrier Lock field should show "No SIM Restrictions" if the phone is unlocked. Apple explains the requirements in its guide to using an eSIM abroad.

For a quick starting point, check your phone's compatibility. Regional versions of a phone can differ, so use the model you own.

Open your private trip page and follow the instructions for that eSIM. If you need to scan a QR code, have it available on another screen. Keep the setup details private. Save your accommodation address and transfer information offline too.

Set the travel eSIM as your data line after arrival

When you're ready to connect in a covered destination, turn off airplane mode and enable the travel line. Select that eSIM for mobile data, then apply the roaming and network settings in your plan's instructions.

On iPhone, the data-line choice is under Settings, Cellular, then Cellular Data. On Google Pixel, start under Settings, Network & internet, then SIMs. Menu names can vary with the software version. Google's dual-SIM instructions explain the separate choices for data, calls and texts.

If the plan requires data roaming, enable it on the travel eSIM. Keep data roaming off on your home line if you don't intend to use your home carrier's roaming data. Review automatic data switching as well, so your phone doesn't use the other line unexpectedly.

Keeping your home line active can still involve carrier charges, including for calls. Check your carrier's terms if you need that number while abroad; choosing a travel eSIM for data doesn't settle those charges.

Briefly turn off Wi-Fi and load a webpage to check that mobile data works. If it doesn't, return to the plan's setup instructions and confirm which line is selected.

If you've already installed it early

Check the plan's status and validity information in your trip page. Installation alone doesn't tell you whether the clock has started; the activation rule still decides that.

Avoid deleting the eSIM while trying to fix a problem. Apple specifically advises against erasing an eSIM as a troubleshooting step unless your carrier directs you to do so.

If you're unsure whether the plan has started, contact support with your departure date and the message shown on your phone. Keep the eSIM installed while you get help.

Choose a plan for the whole trip

Count your arrival and departure days, and include any stopover where you'll need mobile data. Compare that itinerary with the plan's coverage and validity before you buy.

Browse plans for your destination to compare the current options.
