Hi,

Regarding receiving pictures ensure that the following setting is turned on.

Go to Menu > Settings > Wireless and Networks > more > Mobile Networks > Data Connection > On

Regarding not receiving texts try the following:

Go to Menu > Settings > Apps > all (swipe right )> Scroll down to Messaging, tap to enter then tap force stop and then tap clear data/cache, then shut down your phone and then restart it and see if clearing cache solved your problem, by sending a text to your phone (from another phone).

If it is still not working contact your mobile phone service provider's technical support section.
