This is the single most common reason a travel eSIM appears "dead" on arrival. Turning on Data Roaming for the eSIM line is required and is completely safe with a prepaid plan.
On iPhone
- Settings → Cellular → select the Movia eSIM line.
- Turn on Data Roaming.
On Android
- Settings → Network & Internet → SIMs → select the Movia eSIM.
- Turn on Roaming.
Worried about charges? You can't be billed extra — a Movia plan is a fixed prepaid data bucket. Roaming just lets it attach to the local network.
