O2 SIM in 2G phone

Do O2 SIMs work in a 2G phone?

Not if it's a 2g only phone.

You'll need a giffgaff sim for that.

O2 sim cards do work in 2G phones, i have one that gets used in a Nokia 8810 and a Nokia 6150 when I need to (and thats with my 5G sim card's both Consumer and Enterprise)

You may need a sim adaptor...

Thanks...I am now confused by the different answers. Will have to see if I can cobble together an old phone with my current O2 SIM and see what happens. I need a new SIM as I am trying to get a simple mobile for my elderly mother (so 2G) and just want a low cost unlimited call tariff (£8 on O2) although giff gaff do unlimited calls at £6 per month. I'd hoped not to go to giffgaff as I like to have the option of calling support...however, my experience of customers service at O2 today has been appalling so maybe it's not worth pursuing and I should just go with giffgaff which seems to be O2 anyway I believe. 

Thanks for the very prompt replies!

giffgaff is the same as O2 but cheaper and with better customer service (from the forum support). 

You can also control more settings in the giffgaff control panel rather than having to queue for hours waiting for someone to answer your call.

You will have issues with an older 2g phone, maybe not on a newer one, but I have to use a giffgaff sim in my old StarTac and Razr phones.

@Confused33 I'd go with the advice of @madasaf1sh 

Here's an article that might be of interest to you: 2G may not be switched off in the UK for another decade | TechRadar

Being able to call O2 support isn't all it's cracked up to be. These days it's practically non-existent. Go with GiffGaff and save a few bob. If you have any questions about anything you can always ask here. GiffGaff has a community too.
