iPhone 13 (5G) Do I need to upgrade existing O2 SIM?

[RichardCheshire]

Whilst I don't live in a 5G zone, there are towns and cities near where I could use 5G. My current O2 4G SIM is in an iPhone XR.

If I upgrade, do I need a 5G sim or will my current SIM work?

Your current sim will work for 4g but not 5g.

Get a new 5g sim from O2 when you upgrade.

In addition to what @MI5 says above, @RichardCheshire: O2 also need to enable 5G on your account - it should come as part of the 5G upgrade from O2. Three things needed to avail of the areas with O2 5G signal: (1) a 5G-capable handset, (2) a 5G SIM in the handset, and (3) 5G services enabled on your O2 account. 

More on O2's 5G coverage and plans here: https://5g.co.uk/o2/ Good luck!

Thank you very much

I upgraded to i13 a couple of weeks ago and the sim was my old one and it still works in 5g zones and seems to register the  5g.

You must have had a 5g sim already then.
