What Exactly is Number Porting / Mobile Number Portability?
Mobile Number Portability is a service that allows mobile users to change their service provider or network and keep the same phone number.

By eliminating the need to get a new number when switching mobile plans or networks, customers have more freedom to choose eSIM plans that suit their needs and reap the benefits of new technologies like embedded SIM cards.

Rules for porting your mobile phone number to an eSIM differ from country to country, but the process is straightforward in the United Kingdom.
How Does Number Porting to an eSIM Work in the UK?

Porting an eSIM in the UK involves getting a PAC and sending an email.

A Porting Authorisation Code (PAC) is usually made up of nine digits and is valid for 30 days. You must request this code from your current provider. Your new provider will need the code to schedule the transfer of your number.

Can a Carrier Refuse to Port a Number?
The industry has been plagued by dodgy ISPs and mobile providers who are determined to block customers from switching to other providers and taking their number with them.

According to Ofcom, the regulator for the telecommunications industry, “Under the General Condition 18 (GC18) rule UK consumers are supposed to be able to keep their phone number when changing provider.”

This means mobile users in the UK can transfer their phone number and providers are not allowed to withhold the porting code.

Getting the PAC number shouldn’t take more than a few hours. Most providers should be able to give it to you immediately.
