Have you just received a new SIM from us? Then this is the place to find out what to do next. It all depends on whether your SIM is for 1) a new connection, 2) an upgrade, or 3) a replacement. Here's what to do in each of these situations:

 

 1. New connection.

If you've purchased a new connection, the SIM card you receive should already be activated. Simply pop it into your handset, and you're good to go.

SIM not working? This article might help: 

 2. Upgrade

 If you've recently upgraded with us, your new plan allowances should now be available to use on your current SIM.

You might receive a new SIM card in the post. This is just in case you've upgraded to a new phone, and your current SIM doesn't fit. So, if your existing SIM is fine, just store the new one in a safe place in case you need it in the future.

 

If you ever need to use the new SIM, you can activate it, in the iD Mobile App or My Account online by:

  • Logging in to the app or online account. 
  •  Going to the 'My Services' page 
  • Clicking 'Activate my SIM'
  • Scanning your SIM card barcode or entering the 19-digit number printed on the SIM cardholder*

Once you click 'Activate your SIM', the new SIM will be activated within a few hours. 

*If you don't have the cardholder any more, don't worry - the number's also printed on the back of the SIM card itself. It's an 11-digit number, and you just need to add '89442001' to the start of it if you need to input it somewhere.

If you're not registered for iD Mobile App or My Account online, you can activate your SIM here. 

 

 3. Replacement

 If you've received a replacement SIM because your old one was lost, stolen, damaged, or the wrong size, you will need to activate your new SIM. You can activate it in the iD Mobile App or My Account online by:

  • Logging in to the app or online account. 
  •  Going to the 'My Services' page 
  • Clicking 'Activate my SIM'
  • Scanning your SIM card barcode or entering the 19-digit number printed on the SIM cardholder * 

Once you click 'Activate your SIM', the new SIM will be activated within a few hours. 

*If you don't have the cardholder any more, don't worry - the number's also printed on the back of the SIM card itself. It's an 11-digit number, and you need to add '89442001' to the start of it if you need to input it somewhere.

If you're not registered for the iD Mobile app or My Account online, you can activate your SIM here.

Hi @Lyraxylia,

You will be fine to continue using the old SIM card. The plan will still update. 🙂

@Jack Ryan,

Is it a new iD Mobile SIM or a replacement SIM card?

If you have upgraded or received a replacement SIM please click HERE to activate it.

If it’s a new SIM card it should already be activated.

Thanks,

Kash

I have changed contracts with yourselves and received a new sim card. I have had it in over 48 hours and still no service, I have tried flight mode and turning it on and off a number of times.

Hi @alfaz.di.pi 

As you are an O2 customer, I think it would be best to speak to O2 directly regarding this.

Hi iD, 

I received a replacement sim but cannot activate it because I can’t get My Account to work (on both my phone and laptop). If I press ‘log in’ etc. it freezes up or doesn’t do anything. Can an iD operative activate my sim on their end? 

All the best, 

Joe

Hello Will thanks for the reply. To clarify, my present SIM with O2 is not lost, it is also working ok , and I have not or will not upgrade my phone. So why do I have  to swap a new o2 SIM into my phone.

Hi @alfaz.di.pi 

Not sure what your sim issue with O2 is. Do you have an ID sim?

I do not have an issue with my present SIM which I pay monthly, I am just asking why I have been sent a new SIM. Is O2 changing something?.

Hi @Ilovemycat 

 

After trying the recommended steps, please turn your phone off and back on again, this normally helps with the SIM registration.

Please come back to us if you are still having issues after trying the reboot.

I just updated the app and signed in and it has automatically activated a replacement SIM i was sent a couple of months ago - I threw this SIM away as I didn’t need it.

 

How can I get my original SIM reactivated? I need phone access urgently for work purposes!
