Is it true that the mobile SMS says that the phone bill can be overdrawn by 600?

It may be true that mobile phone short messages suggest that the phone bill can be overdrawn in 600 yuan, but it should be based on the actual situation.

At present, the three major operators have launched overdraft services, and the maximum amount of overdraft consumption is generally 50 yuan, but the specific amount and charging standard need to be based on reality. If you need to handle this service, you can call the operator's customer service phone to consult related services.
