I have a question regarding roaming. What happens if a device having a SIM card with roaming not enabled, leaves the country? I will no longer be registered in the network and creg will return 0,2 or 0,3? Is there a possibility to subscribe to this? What would be the difference between the fact that the SIM tries to enter roaming but is not enabled for it and the fact that there is no signal in its area and that is what causes the registration to fail?
Basically i want to be able to know when i am in roaming and when not.
