eSIM for calls and a phone number: calling abroad with a travel eSIM
2026-11-03 · goAFK
Short answer
- Travel eSIMs, including goAFK, are data-only: no local number for regular calls or SMS.
- Call over Telegram, WhatsApp or FaceTime on the eSIM data; your usual number keeps receiving calls and SMS on your home SIM.
Calling with a data-only eSIM
- Use messaging apps for calls over the eSIM data.
- Keep your home SIM on for incoming calls and SMS codes; turn off its data roaming.
- Need a local number for landlords or work? Buy a local SIM from a local carrier, usually with a passport.
Does a travel eSIM have a number?
Most travel eSIMs work as data-only SIMs: the profile has a technical number, but you cannot call or text from it. goAFK plans are data-only. In return they are sold without ID and cost less than plans with a number.
When you need a local number
A local number helps if landlords, employers or couriers must call you on a local number. Local carriers sell those SIMs or eSIMs, usually with a passport. For a 1–3 week trip, data and messaging apps are usually enough.
