Dear everybody, I am from India. I am coming to Shenzhen for the Medical trade fair called as CMEF from April 18 to 21. I want to buy a China mobile SIM there. What is the procedure for getting SIM there. Last time I went to Suzhou. But the staff at the China mobile office does not know English and she did not understand what I need. How to solve it now ? But I keep my old China mobile SIM which I bought at Suzhou on October 28. Can I use it by recharging it again ?
