When I first decided to use my Indian number in china, my friend asked me to use his uniconnevt SIM card for china and because he recently used their services, I trusted the service. To sum up my experience with uniconnect- do not even use their services if offered free of cost for lifetime! The network was so bad there, I could barely make calls. And every call was so heavily charged and after 3 days I got a message saying that to save from the validity getting expired I should recharge the sim with an x amount for uninterrupted services! While as per my knowledge and confirmation from Rohit, they sim was still valid for 30 days. This is a really bad example of customer services. It would be been better to use my Indian number than use these poor  services..
