Check your selected plan’s activation rule before buying or installing. Installation downloads the eSIM profile; the validity clock may start when the eSIM is issued after purchase, when it is installed, or when it first connects to a supported network. Some plans must be installed at the destination.
For a plan that starts on its first supported network connection and allows installation before travel, prepare it over reliable Wi-Fi before departure. Seeing the profile in settings confirms installation; check your order details to find out whether validity has started.
A simple travel timeline
- Before purchase: confirm your exact phone model supports eSIM, is carrier-unlocked, and that the plan’s activation rule fits your travel dates.
- If your plan allows advance installation and starts on first connection: install over reliable Wi-Fi before departure. For other activation rules, follow the timing and location stated on the plan.
- After installation: label the line Wanderly or Travel. Turning it off does not pause validity that has already started; do not delete the profile to try to restart it.
- On arrival: turn the travel eSIM on, select it for mobile data, enable data roaming for that line, and keep data roaming off for your home SIM.
- After connection: test maps or a simple webpage before leaving airport Wi-Fi.
How long does eSIM activation take?
Downloading the profile and connecting to a network are separate steps, so there is no single activation time for every plan and phone. Use reliable Wi-Fi for installation, then allow time for network registration once you are in a supported country. A profile waiting for a destination network is not necessarily broken.
If you have arrived and still have no data, check the selected data line, roaming setting and the plan’s APN instructions. Keep the installed profile and contact support if those checks do not resolve it; deleting it can prevent another installation.
Why advance installation helps when your plan allows it
- You can use a second screen to scan the QR code.
- Home Wi-Fi is less likely to interrupt the profile download than airport Wi-Fi.
- You have time to confirm the eSIM appears in settings and contact support if it does not.
- Your primary SIM remains available while you prepare the travel line.
Check the plan-specific activation rule
The selected plan and order details are the authority. For a first-connection plan, check the covered countries: a regional or global plan could connect while you are still at home or during a stopover. If validity starts on installation, time installation for when you need the service. If it starts when the eSIM is issued after purchase, delaying installation will not preserve those days.
Frequently asked questions
Will installing the eSIM start my plan?
It can. Some plans start on installation; others start when the eSIM is issued after purchase or first connects to a supported network. Check the selected plan before buying and installing.
Can I install the eSIM at the airport?
You can, but private Wi-Fi at home is more reliable and gives you time to resolve an installation problem.
Should the eSIM be on before I land?
It can remain off until arrival. Then turn it on, select it for mobile data, and enable data roaming for that line.
How do I avoid roaming charges on my home SIM?
Turn off data roaming on the home line and select Wanderly for mobile data. Keeping the home line active for calls or SMS can still incur your carrier’s charges; check its roaming terms.
