1. "No Signal" does not show up in the indicator bar until WiFi is
switched on
2. When this started happening the maximum amount I've waited is around
10minutes, no signal
it seems like the modem is not there until WiFi is enabled. For example;
WiFi enabled:
root@ubuntu-phablet:/# /usr/share/ofono/scripts/scan-for-operators
Scanning operators on modem /ril_0...
[ /ril_0/operator/24412 ]
Status = available
Technologies = gsm
MobileNetworkCode = 12
Name = dna
MobileCountryCode = 244
[ /ril_0/operator/24405 ]
Status = forbidden
Technologies = gsm
MobileNetworkCode = 05
Name = FI elisa
MobileCountryCode = 244
[ /ril_0/operator/24491 ]
Status = forbidden
Technologies = gsm
MobileNetworkCode = 91
Name = FI SONERA
MobileCountryCode = 244
Wifi not enabled phone rebooted:
root@ubuntu-phablet:/# /usr/share/ofono/scripts/scan-for-operators
Scanning operators on modem /ril_0...

Another thing that resolves the issue is to run
/usr/share/ofono/scripts/online-modem, just found out and tried
