Has anyone had an issue with MMI Invalid code or network issue come up using speed dial?  I can dial from the contact list but not the with speed dial.

    Hey Sue! Typically this error springs up from not holding down the speed dial button assigned to the number you want to dial. For example, if I had Ting Support assigned to 2 as my speed dial, I'd want to hold down 2 for a few seconds on my dialer to begin the speed dial. If I were to press 2 and hit the call button, I would end up with an invalid MMI code error as the device thinks I'm just trying to dial 2 as a full mobile number. Hope this helps!
