Smartphone forwarding
Forward your mobile to Callina with star-codes (no app, no porting).
The fastest way to put Anna in front of your existing mobile number is GSM call-forwarding star-codes. They work on every mobile carrier in the EU and require no app installation, no porting, no technical setup.
Step 1 — Provision a Callina number
In Callina → Settings → Phone Numbers → Provision EU number, pick a country/area code matching your mobile carrier (avoids out-of-network charges).
Step 2 — Activate the forwarding code on your phone
Open the Phone app and dial one of:
| Code | Meaning |
|---|---|
**21*<callina-number># | Always forward — every call |
**67*<callina-number># | Forward when busy |
**61*<callina-number>**<seconds># | Forward after <seconds> of no answer |
**62*<callina-number># | Forward when unreachable (offline) |
Replace <callina-number> with the Callina-provisioned E.164 number from step 1 (no +, e.g. 4366027123456).
Press the green call button. The carrier confirms with a short tone or "Forwarding activated" message.
Step 3 — Verify
Have someone call your mobile. Anna picks up.
Disable / change

Notes
- Forwarded calls bill against your mobile plan's outgoing minutes (not Callina), so use a Callina number in the same country to keep costs down.
- iOS users can also configure forwarding under Settings → Phone → Call Forwarding — same effect.
- Some carriers require the forwarding-on-no-answer time to be a multiple of 5 seconds (5, 10, 15, …, 30).
