So I put in a new contact yesterday, this person had the same area code as me so I didn't need to enter the area code to make a call to this person (which I did and it worked fine). Afterwards, I went to send them a text message, and it wouldn't let me. I kept getting: "Error invalid number. Please re-send using a valid 10 digit mobile number..." OK, so I edit the contact adding 1+area code and resend- nope. It tells me I'm still sending it to the same 7 digit number that I just edited. I remember running into this problem w/my iPhone, so I completely deleted the contact and re-entered it completely from scratch using the full 10 digit number, sent a text to the new contact and...nope. Same error telling me I'm sending it to a 7 digit number. This is very annoying, any one have an idea who to remedy this issue? Thanks.
