There was a news before that someone won an Apple tablet for free, but you have to use your money, such as how much phone bill you pay each month, how many times you pay it, etc. (Don't think that you can't use it if you don't pay it! Or there are other means) the money paid later or the phone bill charged is enough for you to buy several high-end notebooks. I can't remember the news from a long time ago. What I want to say is to keep an eye on everything. This is just one of the means. As far as I know, wasn't there news in the first half of the year? A mobile phone shop congratulated you. You got a mobile phone for free. You can take it, but the staff may ask for your phone number, ID card, etc., and take photos, and then you take it back. The customer service also said that the phone bill you charged every month will be returned to you after one year. In the end, you will know that it is actually a loan for you, and the mobile phone is not delivered at all. It's all your own
