How to remove sim slot indicators on messages?

[Android Central Question]

Anyone have any ideas how to remove the sim slot indicator icon next to sent & received text messages? The blue icons with a "1" or "2" next to each message.

They really look quite awful and I'd be keen to remove them

Any ideas on how to remove these? They're the blue icons beside each message with a "1" or a "2". Screenshot here: https://i.imgur.com/CLZZBrk.png

You can't remove the sim icons if you have two sims. It has to be there to know in which sim you received/sent a message/call. The only way to remove the icons is to have only one sim inserted in the phone.

I only have one SIM but still get the icon. Just need to live with it!
