how to set up international roaming on china mobile sim??
I live in shenzhen but my sim doesn't work when i go across the water to Hong Kong!!
I know u can dial 10086 and set up with the operator but they are ALWAYS busy and the staff in the local branch dont speak english.

Is there a code u can send using their 'text message service center'??

If you have a Shenzhen sim card you can activate Hong Kong roaming service by send text sms.

Apply: send sms BLHKRTC to 10086
Cancel: send QXHKRTC to 10086

You can apply before you left Shenzhen and cancel once you back from Hong Kong. When applied, 2.9 yuan / day will be charged for this service.

By the way in most cities, China Mobile has English hotline service. Maybe it's too busy when you call them.

Guys, does anubody know how to enable GPRS for Shenzhen CMCC while in HK roaming?

The only thing you can do is get near the border of Hong Kong with China and try to get the signal there, then send the above message.

Normally, to activate international roaming for a China mobile number, 1) real name register required, 2) a depost or a min limit of balance may be required.

Then international roaming can be applied mostly 1) at service hall of carrier, 2) by text sms, 3) by internet service, 4) by calling hotline.

The exact procedures are different for the different home location of mobile number and carrier.

I would like to activate my roaming, though i forgot to do it before leaving China. Is it possible to do it from my current location? Romania? What is the procedure? I also want to mention that i have enough balance on my phone. Thank you

You need to activate international roaming first. Contact your carrier.

Hi. I have bought a China Mobile SIM Card. As I visit 3/4 times to China each year, I wish to use the same number. I need to know; if someone can help me to activate or deactivate the SIM from a related website or portal? While buying the SIM Card; the staff told me; I can activate or deactivate any time. If I do not deactivate while leaving China, every month; they will charge a certain amount.

I tried to call at 10086 during my coming back but all are in Chinese? I do not understand Chinese. Can anyone help me to get the exact process?
