Whether you're with Proximus, Telenet or Orange BE: the approach is broadly the same. Below, the steps per network.
First: what you need

### Step 2 โ Via My Telenet (alternative)

## Good to know for Belgium
**Is the Tirza number a Dutch one?** That's fine. Belgian networks can forward to foreign numbers, within the EU too. Your bundle has to support it (most bundles do by default).
**Costs?** On most contracts, forwarding within the EU is free. On prepaid there can be a small charge (โฌ0.05-0.15 per minute of forwarded call) โ check your bundle if you're unsure.
**Clients who speak Dutch and French?** Tirza speaks Dutch for now. French-speaking callers get a callback request; you ring them back yourself. A French version is on the way.
## Problems?
**"Code not accepted"**
Check the Tirza number is complete: `+31` followed by the number, no spaces. On Belgian networks the country code is sometimes required.
Example: instead of `020-1234567` try `+31201234567`.
**"Doesn't work while roaming"**
Outside Belgium forwarding usually works, but not always when roaming outside the EU. Stay within NL/BE/EU to be safe.
