Important Network Compatibility Note:

The TK905 is available in 2G and 4G versions. The 4G TK905 supports both 4G and 2G networks, while the 2G TK905 is compatible only with 2G networks. In countries where 2G networks have been phased out (e.g., USA, Australia, New Zealand, Korea, Japan, Canada, Singapore, China Taiwan), it is essential to use the 4G version or a 3G compatible version if available. For other countries, either version may be suitable depending on local network availability.

4.3. APN Configuration for Online Tracking

To enable online tracking via the web platform or mobile app, you need to configure the APN (Access Point Name) settings. The APN information is specific to your SIM card carrier. You can find this information by checking your SIM card carrier's website or by inserting the SIM card into a mobile phone to find its APN settings.

Follow these steps to set the APN:

1. Activate GPRS: Send the SMS command gprs123456 to the tracker's SIM card number.
2. Set APN: Send the following SMS commands, replacing 'content' with your carrier's APN details. Note that there should be a small blank space after '123456' in each command.
   • apn123456 content (e.g., apn123456 web.vodafone.de)
   • apnuser123456 content (if your APN requires a username, e.g., apnuser123456 vodafone. If not needed, you can omit this command or leave 'content' blank.)
   • apnpasswd123456 content (if your APN requires a password, e.g., apnpasswd123456 vodafone. If not needed, you can omit this command or leave 'content' blank.)
