Attempting Copenhagen public transport with a foreign phone number

I have been on a solo journey through Norway for the past week, and yesterday landed in Copenhagen. I have been having no problem using Entur, and am generally good with public transport, but this is my first time in Denmark, on top of me being alone. I've been doing research, I think the Copenhagen Card might be more than I need, but I'm willing to get it for ease of use. The problem is both the DOT app and rejsebillet require sending an sms message to start, and I don't have a danish phone number. I'm using a data-only esim. So far this hasn't been a problem. It is possible I needed a phone number for Entur, too, but I can't remember as I started booking travel through that app before I left. I was thinking I would mostly walk in Copenhagen, but didn't think about my airbnb being out of town, so it would be helpful to take the bus once or twice a day while I'm here. So I guess my question is, how do I get tickets without a danish phone number? Can I buy a copenhagen card at bus stations? 7-11? If it was possible at the airport I missed my chance; I was very tired when I got here and spent too much on an Uber to get to my airbnb. Please help, I'm feeling a little stranded. --- **Post Details:** - **Subreddit:** r/solotravel - **Author:** u/sleepy_chrysanthemum - **Score:** 5 upvotes - **Upvote Ratio:** 73.0% - **Comments:** 5 - **Posted:** 7/14/2025 - **URL:** https://reddit.com/r/solotravel/comments/1lzhr44/attempting_copenhagen_public_transport_with_a/
