How are sms stored in any phones?

Question

I just wanted to know how all the sms in the phone stored internally?? and how do i access this internal files?

Answer 1

Have a look at the Wammu project. It can access phonebooks, SMS, calendars, etc. on many cell phone types.

Answer 2

Text files in older phones while newer ones may use light weight databases. (Details about Android and iOS in zengr's answer.)

If possible you can browse the file system on your phone. It the phone does not allow that then you will probably have to root it.

Answer 3

It depends on various flavors of phone OSs like Symbian, android, iOS

For example: Android saves its SMS's in /data/data/com.android.providers/telephony/databases/mmssms.db iPhone also used SQLite database internally. /var/root/Library/SMS/sms.db

It's a lightweight embedded SQLite database.
