What about sleep downstairs??

There is no wifi for licensed goods, there is a warranty, and there is no risk of refurbishment.

Parallel goods have wifi, no warranty, and there is a risk of renovation.

Licensed goods can't buy bare metal. Buy**.

If you want to make a 3G data tariff that suits your needs. Wifi doesn't make much sense anymore.

The function is basically the same, parallel goods are not products that enter the market through formal channels, and there is no after-sales service.

Nowadays, the counterfeiting technology is quite high, and many machines can only be identified by professional disassembly.

Okay, no wifi Look carefully at the shell should be able to see if it is refurbished, the key depends on whether you like it carefully.

Parallel Apple mobile phones have wifi licensed Apple mobile phones have no wifi

Good luck

Enter * to see that the number on the screen and the number behind the phone cannot be matched.

The above answers can be faked.!

I'm just making 2 phones!

The serial code of the fuselage can be faked,

First of all, when you go to the store to buy a mobile phone, you must check it in detail:

1) Appearance: whether the shell is scratched, whether it is broken, whether there are scratches on the charging copper sheet, which indicates that the mobile phone has been used and charged, open the mobile phone shell, see if there are too many scratches on the copper plate on the electric board, and see if the copper sheet of the mobile phone touching the battery has scratches.

2) Turn on the phone, check the call log, camera record, ** record, information number record, data traffic record, you can see whether the phone is returned by someone or used by the clerk, the general clerk will take the phone for a few days and then sell it, 3) * Enter to view the mobile phone version, see the mobile phone chip time production time.

4) Look at the mobile phone network sticker, be clear, see if the mobile phone screen is dusty, etc.

2. The power consumption of mobile phones is greater than that of new mobile phones Obviously.

Look at the data socket of the mobile phone imitation to see if there is a phenomenon of rubbing flowers, the feel of the buttons, you can find a new machine to compare, the appearance will be very different, the second-hand refurbished is generally a high imitation of the chassis, and the original case of the hand answer sense is obviously different, the second-hand refurbishment of the Qing Dynasty is trapped in the information has been written, the bad date is useless,

If it is a Nokia mobile phone, you can enter * in the cross-section of the dial to see the production date
