Porting Numbers


eSIM.net fully support MNP (Mobile Number Portability) in the UK for all of our O2 and Vodafone products. It is possible to port from a physical SIM card to an eSIM or vice-versa.

Porting In your number to eSIM.net from another provider

To port your number in to one of our O2 or Vodafone eSIM plans you should firstly contact your current provider and request a PAC code which they are obliged to give you.

Please note that you can only port the number in when you order our O2 eSIM plan. If you want to port your number in after you have already bought the plan then don’t worry. Simply cancel your plan and buy another one ( this time entering your PAC code ). Contact us by emailing porting@esim.net and we will refund you for any outstanding credit on your first plan.

Porting Out your number from eSIM.net to another provider

We also support porting out your number if requested. Just ask us for a PAC code by emailing support@esim.net and then forward this to the operator to which you want to port 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.
How Long Does it Take to Port a Number to an eSIM?
Getting the PAC number shouldn’t take more than a few hours. Most providers should be able to give it to you immediately.

The transfer shouldn’t take more than 48 UK business hours after the PAC number has been sent to your eSIM carrier. Please note that the weekends are not considered business hours.
