The principle of the signal is to receive and send messages by extending the built-in antenna of the mobile phone.

6. Each booster is individually packaged, ready to give as a gift or for resale!

Installation and precautions:

1. Wipe the back of the mobile phone and find the location of the earphone hole (some mobile phones have the charging hole as the earphone hole), which is the location of the main antenna of most mobile phones; if the effect is not good, paste the location of the diversity antenna;
2. Peel off the white adhesive behind the signal sticker and stick it vertically on the back of the mobile phone, with the English letters and the arrow facing up (if there is a film on the back of the mobile phone, it must be torn off, otherwise there is no effect);
3. Restart the mobile phone after pasting, most mobile phones will have a direct effect, and a small number of mobile phones will have the situation of mobile phone signal weakening for a period of time, which is a normal phenomenon. This is the identification and matching phase of some mobile phone antennas for signal stickers. You need to wait 24 hours to see the effect. If the effect is not good, try restarting it several times or adjusting
4. Be careful in the process of installation and use. Do not rub or damage by external force. Keep the signal paster clean. Do not directly touch the front side of the chip with your hand. The surface should not be stained with fingerprint dirt and sweat.
5. The material and thickness of some mobile phone cases will have a slight impact on the chip. Please wear the case for comparison. If there is no difference, install the case. It is recommended not to use the case.
