You’re on a call and move to a different spot in your home, but suddenly the call drops.

The buffering symbol on YouTube videos is a common sight.

You have a feeling that you’re overpaying for your mobile plan.

If you relate to any of this, then it’s time to switch your network.

But switching networks means getting a new number, and this complicates things.

Well, we’re here to tell you that you can switch networks in the UK without changing your number. Read on to find out how.

What Does Switching Networks Mean?

Switching networks simply means moving from network A to network B.

There are multiple ways to do this.

You could purchase a new plan + SIM bundle and get rid of your old number. This allows you to start things on a clean slate.

Another option is to get a new plan + SIM bundle and use it with your old number. You don’t have to deal with the tedious process of updating your new number everywhere.

The process is also pretty straightforward. The next two sections talk about the steps involved in switching networks in the UK without losing your number in detail.

What You’ll Need to Switch Your Number from One Network to Another?

You’ll need the following for the number transfer process in the UK.

01. An active number

Your current number must be active before you can initiate the number transfer process. Don’t forget to settle your dues before initiating the transfer process.

02. PAC

Short for Porting Authorisation Code, a PAC is a nine-character identifier that lets you retain your current number when switching operators. You can get your PAC by sending a text message “PAC” to 65075. The PAC is valid for 30 days from the day of issue.

03. Your new Lyca Mobile bundle

You’re going to need a new mobile plan from the operator you plan to move to. Here we have used a Lyca Mobile SIM-only deal.

04. A compatible smartphone

Your smartphone must be compatible with 4G LTE/5G technology. If you’re getting an eSIM, then make sure your smartphone supports an eSIM.
