Help me please!! Unique problem unable to find on any forums! I have a Samsing Galaxy SII E120 HD LTE and when I receive SMS's no caller ID is displayed (and no number) as such I can't even press the reply button. Caller ID is working fine for phone calls and outgoing SMS's. A furthur problem that may be related is that i cannot send SMS's using other SMS applications but it works fine with the default app. Any solutions?? Love everything else about the phone.....very frustrating!
