How to activate the mobile phone card in M-Zone?

Hello, if you are a new Beijing Mobile M-Zone calling card, you need to dial 10086 locally in Beijing when you use it for the first time, and press the voice prompt to activate it. After successful activation, the system will automatically deduct the preset phone bill from your account. If roaming in China (excluding Hong Kong, Macao and Taiwan), you still need to dial 13800 138000 to activate. After successful activation, the prepaid amount and telephone charges contained in the card will be automatically credited to the account. Please refer to.
