When it’s allowed and what to do if it’s blocked.
Top-ups vs buying a new eSIM: what you need to know.
APN, roaming settings, 4G/5G mode, network reset.
5G depends on the countries covered and local carrier partners. If 5G isn’t available, the connection falls back to 4G/LTE.
Depending on the plan, validity starts either when you activate the eSIM or at the first network connection in the destination. We indicate this when it’s specified.
Settings ▸ Cellular/Mobile Data ▸ Add eSIM ▸ scan the QR code. Then enable data on the eSIM line.
Check mobile data/roaming/APN, restart your phone, then reset network settings if needed.
Often yes, but it’s not guaranteed unless the carrier explicitly allows it.
Most recent iPhones and many newer Android devices support eSIM. Check your phone settings to confirm.
Settings ▸ Mobile Network ▸ eSIM/SIM Manager ▸ add via QR code or activation code.
Some brands allow top-ups. If not, you’ll need to purchase a new eSIM for your destination.
