Global Trackers are dedicated to providing the best tracking package for the right price. There are three main elements to having a successful tracking operation, 1. The Tracker. We have used and tested many brands and their various models, our experience has found Teltonika to be the best tracker. Teltonika are said to be the leader in tracking and telematics in Europe, we can not argue with this. 2. The SIM card. There are many options for SIMs, the most common is to pick up a PAYG. The cost of a PAYG is about £5 a month, and you have to remember to top up. Most SIMs are household brand names such as Giff Gaff or Vodafone, these only work on their own networks. We use a commercial M2M SIM card. An M2M SIM card is primarily used for sending and receiving data. These SIMs are able to provide you with GPRS, 2G, 3G and also 4G connectivity. Our SIMs can deliver roaming services across 172 countries through 294 networks world wide. 3. The Software. We use GPS Platform, the worlds leader.
