Today, I just went to Mobile and got a new card ... with 250 free text messages! Sent 100 text messages, just checked the phone bill, and deducted 14 yuan text message fee. ..

Generally, the package changes of the three major domestic operators will take effect next month, and the package charges will remain unchanged this month.

Your new card has no problem with the old one. However, I estimate that the new package will start next month. The default message these days will be 0. 1 yuan.

Why do you say that? Because your monthly package is 28 yuan, but today is April 28th, and this month will end in two days. If when you apply for a new card, he will charge you for April directly according to 28 yuan, you will definitely not do it. But you haven't paid the 28 yuan, and you still want to enjoy all the contents of the 28 yuan. He will definitely lose money.

One possibility is that he doesn't charge money in the last few days of this month, and you call and send text messages according to the default tariff. However, this is unlikely.

Another possibility is that there are three days left in this month, and he will charge you 3/30*28=2.8 yuan monthly rent, which is also 3/30 of the service in the package, that is, one tenth. The excess will be charged according to other agreed rules!
