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 depends on inventory and delivery
A physical SIM can work with devices that use a removable card. Aelixar reserves eligible inventory to the order before payment and collects a separate delivery address.
The line is not active merely because payment has completed; delivery and fulfilment still need to progress.
- Live stock required
- Delivery address required
- Tracked assignment
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.
- Confirm model support
- Confirm unlocked status
- Consider device-change plans
