Ne, samo u Americi nisu kompatibilini (zaključani), dok će u Europi i Verizon, i Sprint, i AT&T raditi sa svim SIM GSM karticama.
C/P sa store.apple.com:
Choose a network carrier.
Your iPad will work only with the carrier you choose.
iPad with Wi-Fi + Cellular can roam worldwide on GSM/UMTS networks. In countries without compatible LTE networks, iPad with Retina display will operate on GSM network technologies such as HSPA+ and DC-HSDPA. When you travel internationally, you can use a micro-SIM card from a local carrier.
P.S.
Ne pričam o iPhoneu, već o iPadu!!!
Sve navedeno je za iPad 4 (trebalo bi raditi i na iPad 3), dok na iPad 2 CDMA verzija NEMA SIM slot.
