M-Zone and1Why can't 0 yuan call and send text messages? Is it illegal?

It won't be useless. Maybe your 10 yuan is a complimentary phone bill instead of a basic phone bill. There are many discounts on recharging now. For example, now we charge 100 to send it to 40 yuan, and then 100 is the basic phone bill, which can be used to handle all business, while 40 yuan gives away the phone bill, which can only be used to deduct the package fee and voice communication fee, and cannot be used to send messages.

If your basic phone bill is insufficient 10 yuan, when you make a phone call, you will be prompted by voice that there is not much balance in your card, asking you to recharge it, but the phone can still be connected and the message can be sent out, so I think your basic phone bill is insufficient. Now 10086 yuan is a complimentary phone bill. Please call the customer service hotline 1086.

By the way, the enquiry hotline of Guangdong's dynamic balance and remaining information is 10086 1 1, which is very convenient!
