My mobile plan is 1 yuan for 1,500 minutes of calls.

admin

It was a 1 yuan package that provided 1,500 minutes of talk time back in the days when there were no family short numbers (the ones starting with 551). At that time, I subscribed to this package and now realize how useless it is as I mainly use WeChat voice calls instead. Currently, I still have the family short number and I'd like to challenge mobile. How do you杠？ Do you杠的时候用什么手段，或者有什么术语？我希望杠掉这个1,500分钟，能否转换成流量，或者限制通话号码的数量呢？有没有可能呢？
