Hello. We are using a lot of Teltonika devices. Basically it is a FMB125 model. Some of those devices we are using in roaming with TravelSIM. And sometimes we have the problem when devices move abroad.
They stop send data to server, but they gather data and save to memory. After few time devices start to work and unload saved data.
This model of tracker has a lot of settings. Which settings do we need to check at first? Do you have some standard recommendation for settings of this model when it works with TravelSIM? Thank you.
