Travel eSIM FAQ
- Is a travel eSIM the same as roaming?
- A travel eSIM still needs a local carrier profile, but prepaid travel plans use transparent allowances instead of unpredictable roaming rates.
- Do I keep my primary number?
- Many travellers use eSIM for data while keeping their home number on the primary SIM for SMS and calls—device settings vary by model.
- How fast is activation?
- After purchase you typically scan a QR code or install a profile in minutes—allow a Wi‑Fi moment at the airport if you install on arrival.
