New Sim 1 - No Incoming Calls

[kalliber1988]

Xiaomi Redmi 4
MIUI ver : 8.3 - 7.5.11

No incoming calls using sim 1 and "automatic LTE" . Subscriber out of network coverage. When I try to make a call I wait 20 seconds to hear the signal. If I switch to "automatic 3G" mode the calls will work normally , but internet not ...
