This guide explains how to switch from Mozillion to EcoTalk and keep your mobile number.
Most number transfers complete within 1 to 2 working days once EcoTalk has your PAC code.
If you want a new number instead, text STAC to 75075 and give the code to EcoTalk.
Mozillion and EcoTalk both run on EE's network, so your coverage will not change when you switch. You are changing provider, but your signal will still use the same network.

To keep your number, request a PAC code from Mozillion and give it to EcoTalk.
You can usually give EcoTalk your PAC code when you order, or after your new SIM card or eSIM has been activated.
1. Request a PAC code from Mozillion
Here is how to get your PAC (Porting Authorisation Code) from Mozillion:
- Text: Text "PAC" to 65075 from your Mozillion phone. You will get a text back with your code within a minute. This is a free service from Ofcom (the UK's communications regulator).
- Phone: Call Mozillion on 020 3893 8441.
- Email: Email help@mozillion.com and request your PAC code.
- Online: Use Mozillion's online contact form to request your PAC code.
2. Order a SIM only deal from EcoTalk
If you have not ordered yet, compare current EcoTalk SIM only deals below.
If you already have your new SIM, continue to Step 3.
If EcoTalk asks for your PAC code during checkout, enter it there. If not, wait for your new SIM or eSIM to activate, then give EcoTalk the PAC code using the method below.
EcoTalk plans are rolling monthly and the network puts profits into nature restoration projects.
EcoTalk does not run a credit check, so there is nothing to wait for during sign-up.
3. Give the PAC code to EcoTalk
Once you have your PAC code, here is how to give it to EcoTalk:
- At checkout: Enter your PAC code when you order your EcoTalk SIM.
- Phone: If you have already ordered, call EcoTalk on 033 3800 5500 and give them your PAC code.
4. Wait for your number transfer to EcoTalk to complete
EcoTalk will send the transfer request to Mozillion.
Your number should move to your new EcoTalk SIM within 1 to 2 working days.
