How to keep your number when changing SIM to Talk Home Mobile

Changing your SIM should feel simple. 

But the second your phone number gets involved, it suddenly feels a lot more personal. 

That number is tied to your bank, your WhatsApp, your work contacts, your family group chats, and probably a few delivery drivers who can never find your house. So when people start looking up how to keep your number when changing SIM, what they usually mean is this: 

“Please let me switch networks without creating chaos.” 

The good news is that you can keep your number when moving to Talk Home Mobile, and the process is much easier than most people expect. 

You need a PAC code from your current provider, your new Talk Home SIM has to arrive and be activated first, and then you complete the port-in request. 

In many cases, if the transfer is requested before 5pm, the number moves over the next working day; after 5pm, it usually takes 2 working days.  

First, what is a PAC code? 

A PAC code is the code that lets you move your existing mobile number from one provider to another. 

In the UK, the quickest way to get one is usually to text PAC to 65075 from your old SIM. Your provider must send the code back, and it stays valid for 30 days.  

That means you do not need to ring around begging to keep your number. 

You just ask for the code, keep it safe, and use it when your new Talk Home SIM is ready.  

The order matters more than people think 

This is where a lot of people get confused. 

If you are moving to Talk Home Mobile, the process is not: 

get PAC, instantly transfer number, then wait for the new SIM. 

It is actually: 

• Order your free Talk Home SIM  
• Wait for it to arrive  
• Get your PAC from your current provider  
• Activate your Talk Home SIM  
• Submit the port-in request using the PAC code  

That order matters because Talk Home’s port-in process only works after you have received and activated the new SIM.  

A real-life scenario 

Let’s say you have had the same number for eight years. 

Your family knows it. 
Your boss knows it. 
Your doctor knows it. 
Your food delivery apps know it. 

You find a better deal on Talk Home Mobile and want to switch, but the thought of losing the number makes you delay the whole thing for another month. 

That is exactly the kind of situation this process is built for. 

You are not starting from scratch. You are just moving the same number onto a new network.  

How to Switch Your Number to New Talk Home Mobile SIM? 

Here is how you can easily switch your existing number to Talk Home Mobile: 

Order your Talk Home SIM first 

Before anything else, order a free SIM. 

The SIM usually takes around 1 to 3 working days to arrive, and you can only move forward with porting once the SIM is in your hands.  

So, if you are wondering how to keep your number when changing SIM, the first practical answer is: 

do not request the switch too early. 

Get the new SIM first. Then do the rest. 

Get your PAC from your old provider 

Once your new SIM is on the way, get your PAC code from the provider you are leaving. 

Again, the cleanest way is to text PAC to 65075 from your old SIM, not the new Talk Home SIM. 

This is one of those small details that saves hassle. Wrong SIM, wrong step, unnecessary confusion. 

So, keep it simple: old SIM for the PAC request, new SIM for the switch. 

Activate the Talk Home SIM 

When your Talk Home SIM arrives, put it in your phone and activate it. 

At first, it will usually come alive with a temporary number. That is normal. It does not mean the port has failed. It just means the SIM is active and waiting for your old number to be moved across. 

This is the point where some people panic for no reason. 

They see the temporary number and think, “That’s it, they’ve replaced my number.” 

They have not. 

It is just a holding number until the porting process finishes.  

Submit the port-in request 

Once the new SIM is active, log in to your Talk Home account or dashboard and go to the porting section. 

That is where you enter your PAC and complete the transfer request. The port-in is for UK numbers, and that standard mobile number transfers are different from landline transfers. 

If everything is submitted before 5pm, the number is often transferred on the next working day. If it goes in after 5pm, it usually takes 2 working days. 

A few things people forget 

There are a couple of small but important points worth remembering: 

• Your PAC is valid for 30 days 
• Port-in can only be done using UK numbers 
• You cannot port a number that has already been lost 

These are the kind of details people usually only discover after they get stuck. 

Much better to know them before. 

Final Thoughts 

If you have been putting this off because it sounds messy, it really is more manageable than it seems. 

The short version of how to keep your number when changing SIM to Talk Home Mobile is this: 

• Order the new SIM first  
• Text PAC to 65075 from your old SIM  
• Wait for the Talk Home SIM to arrive  
• Activate it  
• Submit your PAC through the port-in process  
• Wait for the number to move over  

That is it.
