Mobile switching guidance

As a responsible provider, we take our regulatory obligations extremely seriously and in accordance with Ofcom’s General Condition C7.40 to C7.42 we have updated our Mobile Switching Process.  

As of 1st July 2019, customers can now request a PAC (Porting Authorisation Code), STAC (Service Termination Authorisation Code) and/or Switching Information free of charge for up to 25 mobile numbers by text message, phone or online.

What do these terms mean?

A PAC is used to transfer an existing mobile number from one provider to another, stopping the service with the current provider. 

A STAC is used to stop the service with the current provider, the existing mobile number is not transferred to the new provider. A new mobile number will be provided by the new provider. 

Switching Information consists of any early termination charges, any credit balance for prepaid services and a web-link to the existing provider’s Customer Zone login. 

How to switch to Unicom?

The good news is, it’s now even easier and quicker to switch to Unicom Mobile. Our team will give you the opportunity to give us your PAC or STAC when agreeing the contract.  

If you give us your PAC or STAC at the point of sale we will switch your service to Unicom within 1 working day of the SIM card being activated. 

If you do not have your PAC or STAC at the point of sale you can give it to us during your SIM activation or by calling 0161 946 4756. After the SIM card is activated we will switch your service within 1 working day of the PAC or STAC being given to us.  

If the process to switch your service to Unicom is delayed by us beyond 1 working day you will be entitled to compensation as set out in our Number Portability Compensation Scheme, which is available on our website.
