Forwarding to Tirza when you're with Three (UK or IE)
Lebara runs on the KPN network, so the codes are (almost) the same.
What you need
- Your phone with the Lebara SIM
- Your Tirza number (dashboard)
- Enough credit if you're prepaid — forwarding itself is free, but your number has to be active

Step 1 — Choose your flavour
Forward everything or only when you don't pick up / busy. See the KPN article for the difference.
Step 2 — Tap in the code
Forward everything:
**21*[tirza-number]#Only when you don't pick up or are busy:
**61*[tirza-number]*11*30#Screenshot: phone screen with the code entered
Step 3 — Test
Have someone ring you or use the test call button on your dashboard.

## Worth knowing for Lebara specifically
**Prepaid with low credit?** Make sure you have at least €2 credit. If you've run out, forwarding sometimes won't work.
**Swapped your SIM?** After every SIM swap you need to tap the forwarding code in again. It's not "set once and done".
**International bundle?** Lebara's international bundles sometimes only support forwarding to Dutch numbers. Your Tirza number is a Dutch number, so that's fine.
## Problems?
**"Code invalid"**
On Lebara: restart your phone once. Sometimes the code hangs on first use.
**"I'm getting an error in English/Hindi"**
Lebara's messages aren't always in Dutch. The meaning is the same: "Conditional forwarding activated" = you're set.
