What do you mean, "you have run out of self-written text messages this month"?

Credibility is the maximum amount that a mobile phone can owe.

In the past, when mobile management was not perfect, didn't many people buy cards and owe hundreds of dollars to throw them away?

Have you ever heard of anyone who owes hundreds of dollars and then throws cards? Because Mobile has updated the database and archived the records of users who owe money, it is not clear which year it started.

Credibility is related to two aspects: one is the service life and consumption amount of mobile phone cards.

Second, bad records.

For example, if you owe money to buy a mobile phone card now, throw it away three to four times in a row. As long as your card balance is zero, your card cannot be called or answered.

Bad records can't be removed, that is, a university professor who is often said by foreigners, was recorded twice a year for evading tickets by bus and then resigned from the university.

Now, when the phone bill with no bad record is zero, although you can't make a phone call, you can still answer it.

I thought I still used my card four times when I was in college, so now I can't make a phone call or answer my cell phone as long as I have no money.

My brother's card, which he used from college to graduate school now, can owe more than 300 yuan.

It is said that if there are too many bad records, you can't get a mobile phone card, just like using a credit card. If the overdraft is not repaid, you will not only bear legal responsibility, but also be unable to borrow money for life. When I was working in Nanjing, a colleague got a 20,000-yuan card. Later, I don't know why I overdrawn 20,000 yuan, which constituted fraud and was sentenced to three years.

I guess your mobile phone may have the function of checking credibility, just like some people's mobile phones have the function of refusing calls and text messages. After being set to refuse, you will fail to send a text message when you call him, but some mobile phones don't have this function, right?
