I can't text a certain number...
I blocked and deleted a number (my friend) after a little altercation we had back in January.
Now, after thing have worked out, I readded her number back to my contacts. My phone didn't recognize it as the blocked number, so nothing was in my blocked list. Yet, everytime I try and text her, the text never goes through, it just saying 'Sending' at the top.
Can someone help me figure out what's wrong?
