There is a network access license behind the battery of a licensed mobile phone.

1. The back of regular mobile phones is affixed with the "Network Access Permit" logo of the Ministry of Information Industry, while parallel mobile phones are not.

Second, the configuration of regular mobile phones, including batteries and chargers, are affixed with the laser anti-counterfeiting mark of the original manufacturer, and parallel mobile phones generally do not have this logo.

3. Personally confirm whether the dealer's warranty is consistent with the manufacturer's warranty regulations, and parallel mobile phones cannot enjoy the warranty and maintenance services provided by the original manufacturer or in line with the original manufacturer's technical standards.

Fourth, in terms of appearance, regular mobile phones are more delicate and the keyboard is smooth; Most parallel mobile phones have a rough appearance, a muddy color, and a keyboard with signs of wear.

Judging from the SIM card slot and back label, the licensed logo is S308, and the parallel product revision machine is S300. The licensed goods on the origin are Tianjin Samsung Communications, and the revision machine is not marked or not.

Labels, battery labels, mobile phones, manual packaging, and warranty are all in Chinese Simplified, and the revised machine is in Chinese Traditional or none. The network access permit and the licensed fluorescent anti-counterfeiting mark can be seen under the purple light, and the revision machine is forged or not at all.

Use a small coin detector, after removing the battery, there is a blue label on the back of the fuselage with access to the network, and the label is illuminated with a self-examiner, and those with the word cinn or other words are licensed.
