Sounds great John! Unfortunately, cellular service is really spotty to non-existent on the Main Trail. We have seen people able to connect from the windows along the trail between Trail Crest and the summit, and a few can connect from the summit. I've been able to connect on the summit only on the edge north of the summit hut.
Due to the spotty connections, be sure to set your phone on airplane mode to save its battery, and only try to connect when you really want to.
Have a great trip! Looking forward to any pictures and such that you can provide.
