Buy and install your Wanderly eSIM before departure while you have dependable Wi-Fi. Installation downloads the profile; activation usually begins when that profile first connects to a supported network in the destination.
Those are separate events. Seeing the eSIM in your phone settings means it is installed, not necessarily that its plan validity has started.
A simple travel timeline
- Before purchase: confirm your exact phone model supports eSIM and is carrier-unlocked.
- One to several days before departure: buy the plan and install it over private Wi-Fi.
- After installation: label the line Wanderly or Travel, keep it turned off if you are still at home, and do not delete 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.
Why installing before departure is safer
- 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
Most Wanderly travel plans start when they first register on a supported network, but the order details are the authority for your plan. Do not assume every provider uses the same trigger. If an order says validity starts on installation, wait until closer to departure before installing it.
Frequently asked questions
Will installing the eSIM start my plan?
Usually no; most plans start on the first supported network connection. Check the activation rule shown with your specific order.
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?
Keep the home line available for calls or SMS if needed, but turn its data roaming off and set the Wanderly eSIM as the only mobile-data line.
