Because of my work on GPS vehicle tracking I was involved in vendor selection for the cellular portion and learned a great deal. BUT this only means that with what I learned my answers are going to be specific to my limited knowledge.
Most of your questions are put to your carriers. It's not something that would be in our control unless we are a carrier.
We are a MVNO in Iran. We have also recently contracted a carrier for roaming. But this carrier, which our subscribers connect to their network and go inside roaming and roaming, keeps track of our subscribers. They call it retention.
Can I have my catalog about anti-retention devices in roaming?
I wanted to see what are your tools and ways to get out of this retention?
further i want to know that name of parameters of roaming in SIM card?
Thanks if you answer
I am waiting
