Fix Galaxy S23 Ultra cannot send SMS/MMS from non-primary SIM
In this guide, we will show you a workaround to fix the issue of being unable to send SMS/MMS from the non-primary SIM on Galaxy S23 Ultra. The latest flagships from Samsung do support the Dual SIM Dial Active technology. As a result of this, you could send and receive calls and messages on both SIMs all the time [the inactive SIM wouldn’t go into standby when you are on the active SIM]. However, some users have questioned the implementation of this technology.
According to them, they are unable to send MMS/SMS from the non-primary SIM on their Galaxy S23 Ultra until and unless they switch from the primary SIM to the non-primary SIM. If they don’t do so, then they get the “Can’t send message” error message when sending an SMS from the non-primary SIM. If you are also currently getting bugged by this issue, then this guide will make you aware of a nifty workaround to rectify this problem. Follow along.

The issue isn’t with the implementation of DSDA, instead, the Google Message app is not functioning along the expected lines. So your best bet is to make to switch over to a third-party messaging app like Textra io Pulse, both of which are free from this issue. However, do keep in mind that whatever app you choose will have access to all your messages, so decide accordingly.
