Question
Can I block messages the same as phone calls?
Community Answer
If you add a number to the reject list as outlined above, it should block all incoming traffic from the number. This includes calls and text messages. It may not block messages through other programs (Gchat, Facebook, etc.) that have messaging programs done via WiFi, however.
