I bought a China Mobile SIM card of Beijing, how can I check my balance? Is there any way to get my calling records? Thanks.

For a China Mobile number, you can directly call China Mobile hotline 10086. If you are roaming, you need to call China Mobile service of your phone number location, such as you have a Shanghai China Mobile Card, and you are in Beijing now, you need to call 021-10086. However If you have an Easyown card, you could call 13800138000.
