How to set up your first travel eSIM
Check your phone's compatibility, learn what starts your plan's validity, and set the right line for data before you land. A practical first-time setup guide.
you set off.Your eSIM, one step at a time.

Check your exact model before you buy
Begin with your specific model and regional variant, not just the brand name. The phone must support eSIM and be unlocked for use with another provider. Start with our before you pick a plan.
On iPhone, Apple's travel eSIM guidance lists which models work and how to confirm the phone is unlocked. On Android, menu names vary; on a Pixel the option sits under Settings > Network & internet > SIMs > Add SIM > Set up an eSIM. Check the manufacturer link in the compatibility checker for your model.
Save the setup instructions before you go
Allow a few minutes on a stable internet connection. Your plan's instructions explain how to install it, whether by QR code, provider app, or manual entry.
Keep a copy of the instructions where you can find them again. If setup uses a QR code, display it on a second screen, or use the provider's method for installing it from the same phone. Hold on to the original details until the plan is working.
Installing the plan and starting validity can be separate steps
Purchasing a plan, adding it to your phone, and starting its validity can be separate events. Read the plan's terms before you install or enable anything, so you know exactly what starts the clock.
Do not assume every travel eSIM starts counting only after you land. Check the supplied instructions so you know which event starts yours.
This matters most when you buy ahead of a trip. A plan's number of days only makes sense together with its start condition.
Select the travel line as your data line
Give the travel line a clear label. When you are ready to connect, choose it as the phone's mobile data line and follow the plan's instructions for data roaming.
Check your home line separately, including any automatic data switching. Keeping that line on can still bring charges from your home carrier. Apple's Dual SIM instructions walk through the separate choices for data, calls, and messages.
A data-only travel plan does not add a local phone number, ordinary calls, or SMS. Decide how you will reach your accommodation and receive carrier verification messages before you depend on either.
What to check if you have no connection
- Make sure you are in a country the plan covers.
- Confirm the travel line is switched on and set as your mobile data line.
- Match your data roaming and APN settings to the supplied instructions.
- Check how much data allowance and validity you have left.
- If you need help, reach the support contact in your purchase instructions over Wi-Fi.
Do not delete the eSIM profile as a first step. Reinstallation rules vary by provider, and removing it can make recovery more difficult. Keep the plan details handy in case you need support.
Frequently asked questions
Is it better to install the eSIM before the trip?
There is no single rule for every plan. A reliable connection makes setup easier, but check what starts the validity clock before installing, so the plan does not start its validity earlier than you intend.
What happens if I delete the eSIM and try to add it back?
Whether you can reinstall it depends on the provider and the plan, so do not assume the same profile can be added twice. Check the supplied instructions or ask the provider before you delete it.
Will the travel eSIM take over my normal phone number?
No. The travel products linked here are data-only, so they do not add a local number. On a compatible device, your regular SIM can stay installed and keeps its own carrier terms for calls, messages, and roaming.
