How to inquire about mobile promotions? Mainly telephone recharge discount!

You can check 10086, and I'll let you know when there are general preferential activities. Then you can also log in to the mobile online business hall, where you can also see that there are also general bus stops that advertise, but it depends on your luck. Hehe, there seems to be a recharge activity in M-Zone years ago, so just pay attention to it.
