as hongkong people, we are always lucky, we have serval ways to transfer our HK telephone number to China mobile, most of the telephone companies can give us a special phone number, the number is for forwarding to any where of the world , so just before i m leaving the border, all i ve to do is to forward my HK mobile to that special number and then forward that number to my china mobile, the best thing is the ringtone remaining the same(Hk ringtone) so my clients dont know i m in China. !^1[ s@1
Now is more easy, cos the telephone company and the China Unicorn, they have a One Card two number, that means you only need on GSM chip but with both number, one HK & the other one for china.
