Yes, we have raised this issue many times, all our customers are facing this problem that GPRS is being disabled.

The problem is that some sim suppliers "steer the data traffic" aiming to move their sim usage from non-preferred expensive networks to their preferred network partners. The teltonika device remain stuck in the voice network of the non-preferred networks and don't scan for another network operator for ages.

Thats why we started  moving away from teltonika as they are good only for local sims in domestic use but not for cross-border with international roaming sims.
