Interesting, I guess a mobile hotspot and use your phone without its sim card with WiFi on connected to the hotspot would protect against this.
A mobile hotspot is effectively just a mobile without a screen. It would only provide protection from this exploit if sms was fully disabled
The hotspot would have its own sim card not the one that was in your phone. The one in your phone was removed in this case. The number of the hotspot is not known to the attacker and the phone can still be used for calls and texts via signal or WhatsApp or whatever
But then you won't get any SMSes. A better option would be to use a second Android device with your main SIM, and use call forwarding and an SMS proxy app. Or you could get a virtual number online, and give that number out to people, and keep your main number private.
