Google Messages is making it easier to text from your second number

TL;DR

• Google Messages is testing a new long-press shortcut to quickly switch SIMs while composing messages.
• The feature reduces the steps required to swap SIMs after Google previously removed the SIM selector from the compose bar and buried it inside the profile page.
• The new method for switching SIMs is a helpful improvement, but still redirects to the profile section instead of switching SIMs instantly.
