Wonder if I buy any of these model direct from China and bring backhere, it can justplugand play usingour SIM,right?

If can use then great cause wife will have a trip to China soon, if able to find any of the mentioned top 10 model, will ask her to buy one to test here

Well, seems like the listed model and the pricing is un-realistic. My friend in China now can't get any of the mentioned model available except for the Xiaochai G6, but only through only purchase and the pricing also RMB999 (as per the earlier forumer claim), not RM350 as claimed earlier.

Just did some google on the Jiayu G4 :

How come the camera spec different than the earlier posted by cranky guy?

Actually I've sent this top 10 list to my friend in China now, but he checked with some of the local store there and can't find any model offer. Think most of it not really launch yet, but some brand name like Xiaochai also not yet heard by local
Well, maybe he's staying in quite a rural place (Chengdu) and product launching not up to date?
