Motorola Photon sending same text message after every single day

Hi friends I have Motorola Photon device with sprint connection and it has started giving me problem. most of my friends are getting the same messages from my number every day. I don’t know whether it is problem with network or problem with my more phones. Please tell me what should I do to solve this?

it looks like problem is with your Motorola Photon device and first thing I would like to tell you that you should try to solve this problem by deleting all the messages from your mobile phone and after deleting the messages from your mobile phone you have to check whether problem get solved or not. if you are still having the same issue then you have to try to solve this problem by doing this steps. First go to the menu in your mobile and then you have to go to the setting. Now after that you have to select the Applications and after selecting the application you have to tap Manage Applications. Now select all and then select the messaging option. now after selecting that clear all the data and then check whether your problem can get solved or not.

if problem still remains after trying above solution then you have to do restore factory setting in your Motorola Photon and after doing the restore factory setting in your Motorola Photon you have to check whether it makes any difference or not.
