Troubleshooting and after your trip

The process is instant. From the moment you purchase and install the eSIM at home (which usually takes under 5 minutes) to the moment you connect upon arrival at your destination. Once you land, just turn on the eSIM in your settings and the connection is established immediately.

What if it doesn’t connect right away?

Although rare, the fix is usually very simple:

1. Check the key setting: Make sure Data Roaming is ENABLED for your eSIM line. This solves the issue 99% of the time.
2. Get help if needed: If the problem persists, visit our Troubleshooting page or message us on WhatsApp and we’ll guide you step by step.

Your eSIM is active and ready if you can browse the internet or use apps like WhatsApp. Follow these steps to confirm:

1. Check the signal: Look at the network indicator (the signal bars) at the top of your screen. If you see “4G”, “LTE”, or “5G” next to the bars, your eSIM is detecting data.
2. Test the connection: Open your browser or Google Maps. Send a message in WhatsApp or open any app that uses data. If it loads, your eSIM is working!
3. Troubleshooting checklist (if you have no connection)
   • Mobile Data: In Settings, make sure your Fulldatos eSIM is selected as the data line.
   • Data Roaming: Ensure Data Roaming is enabled for your eSIM (it won’t incur extra charges).
   • Date & Time: Incorrect settings can block the connection—set them to automatic.
4. Get support: If it still doesn’t work, visit our troubleshooting page or message us on WhatsApp at +52 81 1826 2025.

Deactivate the eSIM: Go to Settings and turn off the eSIM. It will stay saved on your phone so you can reactivate it on your next trip without reinstalling, just top-up data.

Delete the eSIM: Remove the eSIM only if you’re sure you won’t use it again. This action is permanent. In the future, if you need another eSIM, you’ll have to install a new one.

In summary: Deactivate it to keep it ready and enjoy maximum convenience, delete it only if you don’t plan to reuse it.
