I wanted to use the 3G connection of my iPad in China. After “visiting” the 3 big companies in Shanghai, I can say they don’t sell data subscription for less than one year and unlimited does not exist.
I also have bought (180 yuan) a SIM card from China Mobile. I noticed that I can go on the internet. I noticed the APN was “cmnet”.
Then I tried successfully to use the China Mobile SIM card you can buy everywhere for less then 10€.
I will have to refund it once empty, but I’ll comment that post then. I think I will have to plug the SIM card back in a real mobile phone.
Of course I had to cut the SIM card to the micro SIM size.
I was connected to China Mobile and just added APN Settings :
APN name : cmnet
Login : (empty)
Password : (empty)
