I wonder, what’s the purpose of this? GSM is going away and being replaced with IMS which is essentially SIP over a specific APN.
Does this problem also apply to data links (from my experience I’ve never had issues maintaining a data connection despite roaming between cells and even countries)? If not then I don’t see how this effort is worthwhile.
