Good day
We use their product Teltonica Rout240 in various locations in Switzerland. We are basically satisfied, but in individual cases we have recently noticed that individual routers are charging the sim card with additional costs.
With one router, a premium SMS is sent every 5min, which costs $10. This will cost us a lot over the month. But we have no idea how something like this is even possible?
Do you know the problem or can you help us with the reason for this?
Many Thanks for your Support.
