This guide explains how to switch from EE to Mozillion and keep your mobile number.

Most number transfers complete within 1 to 2 working days once Mozillion has your PAC code.

If you want a new number instead, text STAC to 75075 and give the code to Mozillion.

Mozillion runs 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 EE and give it to Mozillion.

You can usually give Mozillion your PAC code when you order, or after your new SIM card or eSIM has been activated.

1. Request a PAC code from EE

Switching from EE and keeping your current phone number is straightforward. There is no need to memorise a new number or update all your contacts!

Here is how to get your PAC (Porting Authorisation Code) from EE:

Text: Text "PAC" to 65075 from your EE 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).
Online: Login to your EE account and choose to Leave EE via your account settings.
Phone: Call EE on 150 from your EE phone or 07953 966250 from another phone.
- Open everyday from 8am - 6pm.
In-store: Pop in to your nearest EE store and request your PAC code.

Requesting a PAC does not cancel anything. Your EE plan carries on as normal until the code is used, and if you never use it, it simply expires after 30 days.

The text with your PAC will also show any early exit fees you would pay or credit you would lose by switching, so check it before you hand the code over.

2. Order a SIM only deal from Mozillion

If you already have your new SIM, continue to Step 3.

If Mozillion asks for your PAC code during checkout, enter it there. If not, wait for your new SIM or eSIM to activate, then give Mozillion the PAC code using the method below.

All Mozillion plans include roaming in 41 European countries and a promise of no mid-contract price rises.

Mozillion does not run a credit check, so there is nothing to wait for during sign-up.

Mozillion offers eSIMs, so you can switch without waiting for a physical SIM to arrive.

3. Give the PAC code to Mozillion

Once you have your PAC code, here is how to give it to Mozillion:

Online: Enter your PAC code at checkout when you order, or log in at mozillion.com/login, go to Edit My Plan in your Dashboard and request your number transfer there.
Phone: Call Mozillion on 020 3893 8441 and give them your PAC code.
Email: Email help@mozillion.com with your PAC code and the number you are transferring.
