China Mobile called and said that in order to give back to its old customers, it would give away 10 G provincial traffic every month. Just keep the current consumption. How to do this?

I sent this directly to you, and it was returned to the customer in June-July. Use up your monthly traffic first, and then use the complimentary 10G provincial traffic. There are also 10G conditions, 5G leisure traffic and 5G video traffic. I didn't use it up in June, and there was a deduction in the province. There are also in July. I haven't given it away since July, so I may have to buy it myself. When you use up the flow of your own package, the mobile phone will see that you are not enough, and this gift will be automatically sent to your mobile phone. I mean, don't take it.
