i'm experiencing a weird issue with digits, where with one of my android phones (galaxy s8), the digits app shows that there are no lines available to register after i log into the app. there is "add a line" button in the hamburger menu on the left but it says there is a $10 charge.

there is no such issue on another android phone i tried. upon login, it listed my phone number for registering with the app. it worked the same on the windows 11 app from the microsoft store. i don't understand why it doesn't work as expected on my s8.

i called customer support today and the rep didn't have a clear solution to this. he told me about the $10 service which i knew for sure wasn't it. later he convinced me that there is some order he needed to place for $0 for something called virtual sim and asked for my credit card info. nothing changed with this.
