3g Sim?

[Jimbo-ish]

I've just got a Sanyo S750i phone from Orange's outlet shop on eBay, which came with a SIM card.

I'm currently using my PAYG SIM in the phone with no issues, but reading here has made me wonder what kind of SIM I have. Is there a way to visually tell whether a SIM is 2.5 or 3G? I can stick a photo up if anybody thinks it would be useful.

I have two Orange 3g sims, they are both greenish in colour

Interesting. Mine is a greenish colour, what shape is the contacts bit? On my 2.5G SIMS it's square with slightly rounded edges, the new SIM's is almost circular. I'll stick up a photo tomorrow.

Guess I could just stick it in and see...

Just registered it and it is indeed 3G. This has got be one of the cheapest ways of moving to 3G.
