What phone do you have that could possibly require 5 mins and an arm out the sunroof just for a GPS fix?

Time to fix can be worse if you've moved since your last fix, or if you're moving quickly. If you don't have a network connection to download the almanac info, it takes 12.5 minutes to receive in its entirety.
Many phones with data service switched off, which might be the case when driving abroad.
Data service has nothing to do with a GPS fix. Nothing at all. No data is used. GPS does not require any internet connection at all.
You are technically true but if you don't have internet connection to get the almanac (future position of satellites) you have to wait 12.5 minutes to download it very slowly from the GPS itself. That's what parent was saying. It works but the time-to-fix is very high.
AGPS uses data service to get the almanac.
Thank you. I learned something from this. How often does that almanac need to be updated, however?
