I am not getting calls or text messages from only one number ( a family member ) . It is very important to get these calls and text messages as it concerns issues that are very important at this time . So why woould I not get calls , no missed call notification , no text ! I got a missed call notification from a friend , so would really like to know how to fix this . I have not changed any settings on my phone , or blocked any calls ....unless the phone did it on it's own. Very frustrating , who has the time to get this all figured out , for what these phones cost we should not have problems & calling should not be such a problem, they should be able to help !!
