TapaTalk may be able to provide push notifications. I suggested to this poster in another thread that they should research their carrier. I know with Verizon where one could use @vtext.com with their mobile number but it seems that Verizon no longer supports it. I don't know if TapaTalk supports push notifications just for a specific thread. I know it's been discussed in the past regarding the Sightings forum and perhaps it works for new posts in a forum but that might produce a lot of unwanted notification volume.
