1. Card Picking pin is a card picking tool equipped in some high-end mobile phones. Using the card pick-up pin to pick up the card is a card pick-up method designed for some mobile phones whose batteries can not be disassembled and save internal space.
Usually, this kind of mobile phone is smaller than ordinary SIM cards (such as micro sim card and nano sim card). The card slot is usually located on the side of the fuselage, and there is a hole switch (unlocking hole) designed for card access, which is similar to the emergency disk access hole of computer CD-ROM.
2. How to use it
The function of the card pin is to install the phone card. If you don't have a card needle, you can use needle-like objects such as paper clips and toothpicks to take and put the mobile phone card.
Hold the card fetching needle, aim at a small hole on the left or right side of the mobile phone, and press down hard until the card carrier comes out.
After the card holder is taken out, put the phone card prepared in advance on it. Common mobile phone cards are mobile or Unicom phone cards. Put it away and push it in directly. The card has been installed.
After the installation, turn on the phone and see if the phone receives the signal. If so, it means that the installation is complete.
