I have a Samsung Galaxy J6 phone and use T-Mobile as my server. I will visit Norway and Iceland this summer, and I hope to use my phone to help me navigate and do translations. Based on this I have the following questions:
- Should I unlock my phone before I leave and get separate SIM cards in Norway and Iceland?
- Where should I purchase my SIM cards? Can I get a reasonable deal in the Oslo and Rejkjavik (Keflavik) airports?
- If I get local country SIM cards, will my current Google Translate program work in both countries?
- If I get local country SIM cards, will my existing Google Maps and navigation program work in both countries? If so, will they display directions in English, but using names visible on road signs?
