Unreasonable sudden switching from iMessage to SMS
Hello,
This problem started quite recently. While texting people over on iMessage, my messages app would suddenly switch to SMS and the FaceTime symbol or prompt on the top right would disappear despite having stable internet and cellular data. Tried switching to cellular data from WIFI and vice versa but the problem still persist. This happens for all my contacts that I normally chat to with iMessage. I also tried restarting and turning airplane mode on and off as a fix. Sometimes it would go back to iMessage and work properly but the issue would keep returning again.
TIA for helpful ideas!
iPhone 16, iOS 18
