The only time a mobile/data connection is helpful but not necessary is for Assisted GPS (A-GPS) where the phone can download the latest GPS almanac (and/or utilise multilateration to provide it's location) which will decrease it's TTFF (Time To First Fix) by GPS from satellites. ie. Instead of taking a cold start of 45 seconds to provide a GPS fix, it might take 20 seconds.
The almanac will be downloaded from the GPS satellites if it can't be obtained another way this is what a normal non-data connected GPS receiver does.
Phone location can also be approximated by other means, (WiFi, etc), but none of them are a requirement for GPS, as @Ath said.
Regarding Dual SIM, some phones use the MicroSD as the slot for the second SIM, you either have Dual SIM or expanded memory capacity, not both.
