Where can I buy a prepaid SIM card in Bergen Airport or Bergen City? Which company/carrier is recommended?

What’s worked for us is to turn everything off, put phone on airplane mode, and just use WiFi when it’s available. We’ve been away for 6 weeks and it’s worked fine! It’s been nice to be a bit disconnected from our phones ;)
