Swap your sim

You may want to swap your sim card if you’re changing phones and need a different sized sim – or if you need a sim with a 4G tariff. 

Once you’ve got a new sim from us, you can swap the number of your original sim to the new one by signing in to My O2 Business and going to My Account.

How do I swap my sim?

The easiest way to request a sim swap is by going to My O2 Business - it’s a lot quicker than calling or emailing. Before you start, make sure you back up all your important bits – contacts, calendar, photos, music or anything else you might need.

You'll need your original sim and number, as well as your new sim. You'll also need the serial number on the back of your sim - it's the long number beginning with ‘894411’.

To request a sim swap:

  • Sign in to My O2 Business and go to My Account
  • Go to ‘Manage devices and select 'Sim swap'
  • Choose the mobile number for which you need a sim swap
  • Type the new sim card number into the box – and be sure to leave the prefix ‘894411’ in place, even if this number doesn’t appear on your sim card
  • Review and submit your request
  • Watch this helpful video on our O2 Business YouTube channel

Sim swaps can take up to 24 hours. Once you lose signal on your original sim, turn your device off, put your new sim in and turn it back on. If you need to, just keep turning your device off and on until you get signal. Then you're all done.

If you don’t have access to My Account when logged in to My O2 Business, speak to your usual O2 Business contact, who can arrange access for you.
