Why didn't you send a message when the mobile phone traffic (20 yuan 50M package) ran out?

Hint. If you haven't received the prompt, you can call Mobile next month and say that I wasted a lot of money online because of your mistake. .

That's my friend. . 5 yuan wrapped 30 samples, which was moved without prompting. . He has been surfing the internet. . Check the phone bill at the end of the month. . More than 300. . Call your cell phone. . I didn't send it when I checked. . Next month, I will refund all the phone bills of last month. . . Sweating,,,

Please call your mobile phone quickly ~ ~
