i’m evaluating a nordic nrf9160 modem for a gps tracking application and have some problems with the right psm settings, when using roaming sim card.
My settings are working with 1nce sim cards. But with emnify sim cards my setting for the active timer is not accepted by the network.
I tried the same values for active time which are working with the 1nce sim card but also with other values. I need something in the range of 20-60 seconds.
Other networks like vodafone are working with the emnify sim cards.
Are there some restrictions for roaming sim cards?
My development is in Germany, but it should also work in Austria.
