eSIM troubleshooting

Turn Data Roaming ON for the VamosData line and select it as your mobile-data line. iPhone: Settings → Mobile Data → VamosData line → Data Roaming. Android: Settings → SIM manager → VamosData eSIM → Data Roaming. Roaming causes no extra charges — the plan is prepaid. Then toggle Airplane mode off and on so the phone re-registers.

Some destinations need a specific APN (Access Point Name) before data flows. iPhone: Settings → Mobile Data → VamosData line → Mobile Data Network → enter the APN from your install guide or country page. Android: Mobile network → Access Point Names → add it, save and select it. Then toggle Airplane mode. If you don't know the value, ask support and we'll send it.

First make sure you're on Wi-Fi — installing downloads the profile. Remember a QR installs only once: if you already added it, look under your existing lines instead of rescanning. Otherwise use manual entry with the SM-DP+ address and activation code from your order, then restart the phone and try again.

Usually no: the QR is single-use, so a deleted profile generally can't be added again. Only remove an eSIM once your trip is over or the plan has expired. If you've already deleted it, contact support with your order number and we'll check whether anything can be done.

Toggle Airplane mode so the phone re-selects the best local network, and check in your account that you still have data and validity left. If it persists, pick another network manually (Network Selection → turn off Automatic) and make sure 4G/5G is enabled for the VamosData line. Still slow? Tell support your location, phone model and the network name shown.
