Hi there,
You'll only be able to override this limit if you can build your own
version of the Android platform with updated settings built-in, or can
get root access to the devices you're using in the field.
Either way, you can alter the SMS rate-limiting as follows:
# sqlite3 /data/data/com.android.providers.settings/databases/
settings.db
To increase the number of SMS messages allowed per period:
sqlite> INSERT INTO gservices (name, value) VALUES
('sms_outgoing_check_max_count', 101);
Or, more simply, to remove the period check altogether:
sqlite> INSERT INTO gservices (name, value) VALUES
('sms_outgoing_check_interval_ms', 0);
However, I'd be more inclined to find a way to not send so many SMS
messages (assuming you can't simple use a data connection). Surely
you can batch multiple answers into a handful of SMS messages? If
it's a simple multiple choice questionnaire, then you could even fit
the entire session into a single SMS.
Anyway, hopefully that helps.
Regards,
Chris
