Sorry to hear the issue. If you are still having the problem the main thing you would want to check is if he device has a full data connection ( can you connect to web). f so might need to restore and update the profile on your device. Try updating your profile Home> Menu> Settings> General> Update Data Profile. If still unable to send please send me a private message and can go further in troubleshooting if need.
Can someone please help me ... Ive tried to find this in the threads.. but no luck. Just got the samsung seek and none of my pictures will send. I can upload to facebook but cant email or send in a text message. I have everything for my phone, so it should send without a problem.. any suggestions, besides buy a new phone! LOL
