Dual SIM settings to check when upgrading to IOS 17

[chefwong]

I have dual sim on my phone. Carrier A: for Data. Carrier B: Default is for phone:voice

After upgrading to IOS17, it seems to have defaulted the data also to Carrier B.

Anyhow, for those running dual sims, check your config post update if you are using SIM 1 for Data and SIM 2 as you main voice line

Im using dual e-sim but have voice & data on each line…
If you want data only on a specific line go to settings, cellular, then cellular data. From there you can choose which line should have data…

I have voice and data on each line.
What was the setting was default data was to user SIM A. Default voice was to use SIM B.
After IOS17 (which wasn't on my radar to check) but it defaulted both to SIM B

I'm having an issue. I use my personal number and work number on one phone. Personal on iMessage and work on sms. Since updating, all of my work contacts that I've set to my business line; however they have iphones and imessage, the business line will not send it forces to personal iMessage. Really don't want vendors or customers having my personal line. It kind of defeats the purpose of being able to disconnect on vacation. Anyone else experience this? If so, discover a fix?
