Hi, I've been experiencing this error for a while and finally decided to investigate.

Phone: Pixel 7 Pro
SIM: 2degrees esim
Plan: prepay monthly

I can successfully send SMS via my Vodafone SIM. Just 2degrees returns error.
"Can't send message with 2degrees - error 41"

I suspect this started occurring when I moved my SIM to an eSIM.

Anyone had this before? Googling the issue doesn't help much.
