GF 07 GPS tracker is not working – 100 % Problem solving trick

Last Updated on August 23, 2022 by technoreview85

Gf 07 is a portable GPS tracking device. It works with the GSM network by sending & receiving SMS.

This device works only with a 2G network.

Before applying this small trick you have to check some necessary things.

  • You have a 2G network-supported sim card
  • Your country has 2G network services
  • Your sim card service provider has a 2G network coverage for your area
  • You have some mobile balance to make calls & sending SMS
  • Your sim card has not any PUK locked

If above all those things are available & your gf07 GPS tracker not working then you can try this small trick.

Now almost all sim cards are mini or micro sim but unfortunately, this gps gf07 supports only standard-sized sim cards so we are using a sim card adapter like in the picture below.

When we are using a sim card adapter sometimes sim connector points do not touch the sim card you can watch this video for details.

To solve this problem you have to use a thin tape (Sellotape) on your sim card it will hold the pressure from the sim connector & help to touch connection points to the sim connectors.

Now you can use a small folded paper chip on the sim card before closing the cover lid

It will solve your problem if your gf07 gps tracker is not working due to a connection problem or not connecting to the network.

I’m sharing this trick because so many users cannot connect their trackers to the network & this trick is completely based on my practical experience with this gf 07 gps tracker.
