I have a Swedish phone provider and use roaming when traveling in EU. I have noticed that it is slow to connect when turning off airplane mode, often without 4G as default.
As I have a budget/low cost operator in Sweden, is there any "priority systems" with the foreign phone providers that allows more "premium providers (in the home country)" better and mor reliable access?
For example I notice other EU nationals when the plane lands with immediate access to 4G etc., While I often have first "emergency calls only", then no 4G. This is only resolved after restarting the phone and toggling airplane mode on an off a few times.
