See below information on everything you need to know about SIMs.


I’ve got a new phone and need a different sized SIM


More info

Go to, log in to My 48 and select Change My SIM from the list on the left hand side:


Simply select Swap my "SIM - I need a new type of SIM" and proceed by clicking on "Order SIM".


There's only 1 type of SIM sold on 48, known as a Trio SIM. This is a normal sized SIM with perforations on it, so you can snap out a Micro or Nano SIM depending on the size you need.


If you're not sure which size you need for your phone, pop the question in our Phones section to ask your fellow 48 members to confirm the SIM type – chances are one of them has experience with that type of phone and can help you out with it.

When you get your new SIM –  log back in to Change My SIM and go to Step 2 where you can register your SIM. You will need to enter the six digit registration code on the SIM card.


Your new SIM should be up and running in 10 minutes. Your number and membership or credit will transfer to the new SIM.


You can only Swap to a SIM you have ordered through the Change my SIM section. If you use a SIM you have lying around your number and account won’t transfer.


I ordered a new SIM but my old one has stopped working

Not to worry though the care crew can work a bit of magic and get your service back.


Contact the care crew hereExplain what has happened and ask that they lift the suspension on your number.


Now this will mean when your new SIM does arrive you will need to contact the care crew to get it up and running again for you.
