The newly opened mobile phone has a short message record.

Generally speaking, the real new machine should be that all records are "0"! As far as your current mobile phone is concerned, there are still five short messages and thousands of bytes of online traffic records left in it. This mobile phone must have been used, no doubt! Common sense tells us that when buying a new mobile phone, we usually only focus on testing the call quality of the mobile phone, and will not try whether the mobile phone can send text messages! There are only the following explanations for mobile phones with residual short messages: 1, which is used by mobile phone sellers to send short messages, but this possibility is relatively low. Generally, the boss who sells mobile phones will give a mobile phone to use! 2, that is, after buying it back, people don't want it, or if there is a problem, take it back for a refund. We know it's ok to get it back within a year or two after buying a mobile phone. As long as the people in the store take it back for a long time and shout it once or twice, they will get a refund. It depends on one's lip service! This second point is the most likely! ! 3, the prototype, take it out as a new machine to sell, do not completely delete the traces of mobile phone use! As for the problem of mobile phone internet residue you asked, if there is a traffic recorder in the mobile phone, there will be residue as soon as you get online! ..... I think it is necessary to give you a lesson on buying a mobile phone here: as far as my own experience of buying a mobile phone is concerned, I only test the sample of the machine, and then ask the salesperson to bring an unopened mobile phone that has never been used, and pay for it as soon as it is mentioned! Why did you try this and buy the one you didn't try? Because the current mobile phone, as long as it is not a cottage or a domestic mobile phone, I personally think it is not necessary to try it before buying it. As long as the mobile phone is new now, there are few problems unless you really buy a bad one.
