I have a Dodo SIM but I can't get it to work with my Vita, with the APN Dodo doesn't come up.
Oh wait I just thought of something - Could it be that you can only use phone type SIMs and not mobile broadband ones???? (mmd or something like that?)
Man this is all so confusing, anyways any help would be awesome.
The 3G Vitas only work with AT&T.
Even says so on the box and instruction manual.
3G Vita also uses WiFi
The WifFi-only Vita can use a WiFi plan from nearly anybody. If you can connect to it, so can the 3G Vita. 3G is only for 3G cell service. A lot of people with them don't even use it (like me.) I use wifi at home and connect to free wifi if I need it when out. I don't have a wifi plan, but I think about getting one sometimes.
