Transferring a Three number to a Lebara sim - is it possible?

I have a Lebara sim primarily to use when abroad, but would like this sim to become my permanent sim but transferring to my existing number, is this possible? Thanks in advance

To port your number to Lebara, the process is generally the same regardless of your current network. You will need a PAC (Porting Authorisation Code) from your old provider.
1. Get your PAC Code
The fastest way to get your code is via "Text to Switch":
Text 'PAC' to 65075 from your old SIM card.
You will receive a 9-digit code via text within a few minutes.
Note: PAC codes are valid for 30 days.
2. Activate your Lebara SIM
Before you can move your number, you must have a working Lebara SIM.
Insert your new Lebara SIM into your phone.
Follow the activation instructions (usually just making a call or sending a text).
Keep a note of your temporary Lebara number (found on your SIM packaging).
3. Submit the Port-In Request
Once your Lebara SIM is active, you need to give Lebara your PAC code:
