Do Tesco and giffgaff SIMs show O2 as the network?

When using a Tesco or giffgaff SIM does it come up as O2 on the screen?

It depends which phone you use the giffgaff SIM in.

Apple devices show O2 UK, as do some Windows Mobile devices.
But most phones show giffgaff.

I know Tesco show up as Tesco not O2, I assume it's the same for GiffGaff but I've never seen it first hand, so I can't give you a definite answer.

Shows O2 UK on all my phones for GiffGaff. I think you need proper network ID configuration on your phone.

Tesco comes up as Tesco on iDevices (and other devices, as far as i'm aware.) Giffgaff has always come up as giffgaff on android devices for me.

Giffgaff shows up as Giffgaff on my rooted HTC Hero. However when doing things such as checking voicemail, it automotically tries to incorrectly use 901, which is the O2 default. But apart from that everything else shows up as giffgaff.
