Open your messages then press the menu button, then go into SETTINGS where you will see "Text message limit", then by touching it you will see a box with a + and - and if yours is showing 10 with a flashing curser, you can then change that number by touching the curser which will bring the keyboard up. dont forget to save the number you input, mine is set to 200 txts, also you can change the amount of MMS messages as well by doing the same in Multimedia message limit. hope this helps ?
Thanks for the reply. What you have mentioned is about the text message limit per conversation.
The actual issue is that when you are sending a group SMS the 10 recepient limit comes into affect. You cannot send the sms to more than 10 persons within a group.
An alternative solution is to install and work with Handcent sms software but i was looking for a solution within the preloaded messaging software.
