No Service Need Something to Communicate with the Outside world

So I finally got to put to the test the Google Talkatone app because during August 4th through the 9th I was in Hamilton NY and my phone had no cell service. I was able to log into the app on my ipad and communicate with the outside world via telephone though. This came in handy because we had to immediately get an updated budget to the US Department of Education for the ASAP Grant that we have and I had to communicate via my ipad entirely. I was able to email back and forth with my assistant and then dictate to him what the conversation should be with the program officer which was easier then continually emailing him. I has to call him numerous times telling him what to do with the budget and how to modify it so that the budget cuts from the government funding could be included and the budget modifications for the current year could be included. It was later sent to the US Department of Education and approved. The only problem that I still have is not being able to manipulate the spreadsheets sent to me. I can't view the formulas or edit them in any of the free apps that are available. I will bring this issue to the CTLT coordinator again.
