EM060K-GL and problem with Kyivstar card in roaming

IoT Modules LTE-A Module
1

I have: EM060K-GL modem in GL-Inet device: GL-E750V2.

I have two Ukrainian Kyivstar SIM cards - one native, and second eSIM i esim.me adapter. Both cards works well without issues when are in home network, but when im in Poland and trying to use it in roaming first card logs very long into roaming network and works but after some time (time randoms from 1h to 3h) i see that “sim card is not registered” and lost connectivity. After restart is the same - works for some time then stops. Tried both cards - the behavior is the same. Looks like using other card’s in Poland in roaming (ex vodafone spain) works without issues.

Can i somehow check modem logs? Why card was logged out from the network?..

OK

Maybe there is newer firmware for my module?

Hi Arybak,

May I know if the Network registration always failed every time or only one time during roaming?
During roaming, the first network injection time in the roaming scenario usually will be very long.

The problem is not with first logging because i know that can take a time. Problem is card is logging off from network after some time, after modem reboot card works…

Hi Arybak,

If my understanding is correct, after the module reboot, the network registration working fine?
