The so-called validity period is until 2050, that is, as long as your mobile phone card is not in arrears and is used normally, you can always use it. The year 2050 is just a virtual number and has no practical significance. The key is that you can always use your mobile phone card normally. This is not the validity period of the phone bill.

Do you need to charge a monthly fee for the CRBT function of your mobile phone card? I suggest you contact your local customer service for consultation. After all, different mobile phone packages have different services, some of which are complimentary services. So I suggest you contact the local customer service to see if there is any charge and whether it can be cancelled.
