Which is the best 3G service, China Mobile, China Unicom or China Telecom?

Printer-friendly version

Hi, I am presently in Shenzhen. I intend to do some travelling around China. I'd like to know which of the Chinese mobile operators, China Mobile, China Telecom and China Unicom, has the best 3G coverage in China? I presently have China Unicom. It's okay for Shenzhen. But, earlier this year, I went to Wuhan and it didn't work at all. I use a Huawei MIFI device with my Apple ITouch.

Thanks in advance for any help offered.
