Hi!
I have a question,
I am a hamateur radio operator and
I already have a regular subscription with my provider. Let’s say i want to change to POC radio for my regular needs and keep my phone number, can I just swap my sim card into the POC radio and continue my subscription? or is it a new subscription with a new provider? If so, what are the monthly fees for a subscription.
