Note* We no longer manufacture and sell these versions of our device, both 2G and 3G networks are being shutdown around the world eventually so all these versions of our devices will stop working depending on the shutdown speed in a specific area.
MM6/MM2 differences when compared to MM5/MM1:
- works in countries where 2G is switched off since it uses 2G + 3G signals, where as MM5/MM1 only uses 2G
- consumes 30% more energy, so battery lifetime is 3-4 months shorter - so MM5/MM1 has longer battery life.
The reason for that are the below improvements:
1. MM2/MM6 provides more accurate GSM approximate location, which helps a lot when GPS signal is not available (underground garages, GPS signal is jammed and so on);
2. Better chances to get a GSM connection. MM6 covers both, 2G and 3G networks - if the 3G signal is low, it will search for 2G service provider and connect to it (and vice versa).
