The mobile phone card is in arrears, but it just keeps going. Every time there is 10 when you arrive, you will be notified by SMS once, and then you will leave it alone.

At present, if the balance of the mobile phone card is less than one yuan, it will stop, and if the balance is more than one yuan, you can make normal calls. This has caused a delay in the collection of mobile charges, because the charges generated by your phone call are not deducted immediately, but are deducted in different periods. In the last call, if the balance of the mobile phone is close to one yuan before the call and the mobile phone has not been disconnected during the call, the delay will increase and the arrears will be more. .

It's not safe. The phone will automatically hang up at any time during the overdue period. This is very bad for customers' business, so I suggest you don't let the balance of your mobile phone be too low to avoid inconvenience!
