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.
