Issues with Mobile Client SQL Update

I am developing a mobile client application that requires a small amount of data entry (numeric text fields, dropdown lists), but cannot get any of my update statements to work on a mobile client. Opening the application via pc works, so I assume it is just a limitation of the networking of mobile clients.

Is this the case? If anyone has a quick fix for a mobile client that’s unable to perform SQL Inserts, I would greatly appreciate the help.
