Samsung jet

This problem is not only related to any particular model but to all the models of samsung that why do samsung mobiles have message memory so less only 200 messages are stored in mobile.
A person like me who receives 100 messages in a day have to delete those messages every day. What is the solution for this ? Is anybody is going to answer my question ?

The only way to prevent this from constantly popping up is to set the phone to “auto erase inbox”. Go to messaging/more/settings/set “auto erase inbox” to “on”. *****, but that’s the only way other than doing it manually…
