5 minute read · Updated 2026-07-31eSIM keeps installation digital
An eSIM is a downloadable SIM profile supported by many newer phones. It avoids delivery time but depends on the exact device model and lock status.
Installation information should be treated as sensitive and used only on the intended device.
- No removable card
- Device support required
- Secure QR handling
Physical SIM needs delivery and later assignment
A physical SIM can work with devices that use a removable card. Checkout collects a separate delivery address without reserving an ICCID; operations staff assign eligible inventory after payment.
The line is not active merely because payment has completed; delivery and fulfilment still need to progress.
- Assignment after payment
- Delivery address required
- Tracked fulfilment
Base the choice on the actual phone
Check the phone model, whether it is carrier-unlocked, and whether another SIM profile is already in use. Choose physical SIM when eSIM support is uncertain.
If keeping a number, the number-transfer requirements are the same regardless of SIM format.
