We have been using FrontlineSMS successfully for about a month now (with more than 500 messages received). But, the program no longer uploads new SMS nor forwards new SMS to the email account.
The phone says, "no space for new text messages" but we have chosen the option to "Delete messages from phone after receiving" and the phone is detected.
If the sim card is placed in another phone then messages instantly start popping up from the backlog.
If you have any suggestions, that would be great!
