Bought a SIM card in Denmark for travel throughout Europe. It took forever to activate (no English language option apparently) and then when I travelled to Italy it didn't work. I went through THREE different customer service chats before we finally figured out how to set my APN to work internationally. Even then, the coverage was intermittent at best. Then I moved on to another country and - guess what? - the card stopped working again. Paid for a month got, at most, 5 days. Terrible.
