Android Question How to remove SMS limit in settings.db

[ThRuST]

I want to remove the SMS limits in settings.db but I have not yet found a solution to this.
Someone posted something about that you can use chmod("/data/data/com.android.providers.settings/databases/settings.db", 0777),
can anyone provide an explanation to how this can be done? Phone.shell etc thanks for any replies.

You will not be able to remove this limit on non-rooted devices.

Ok thanks Erel. I have so far no idea what differes between rooted and non rooted devices I will have to seach google.
I'd appreciate if you can clearify the difference or else I'll look it up. I have found a couple of questions on getting super
user rights and how to manipulate the settings.db database but it seems like advanced. I need it for an app I am working
on it can send out SMS messages to people in customized phone lists. The standard limit for number of SMS is 30 I think.
There's apps for this on Google play that unlocks this limit. They all cost money so I'd appreciate if I can implement it in
my code myself.

See this wiki about rooted devices: http://en.wikipedia.org/wiki/Android_rooting

Which app can remove this limit?

If the limitation comes from your phone-provider: The provider will have an own counter of outgoing sms (if they give you x sms free in a month) and if you are over this limit you will be charged for the sms.
So changing this limitation in this settings ill not really work i think.

Here is a few I've found but have not had the time to test them yet.
Besides, as a Basic4Android programmer I prefer to handle that by my own code.
Glad if someone can assist to solve it.

They all require root access.
