Why would you think that? There&#x27;s no special ROM that prevents Android from loading if the carrier&#x27;s sim card isn&#x27;t loaded. It should still work regardless of sim. Edit: It&#x27;s CDMA, and it would have to identify a network before booting, which isn&#x27;t going to happen; this phone should work fine on wifi without a carrier plan. Question is, did they disable the wifi or GPS the way some similar AT&amp;T phones did?
