I texted my friend last sunday and im pretty sure she will reply. But didnt. So the next 2 days i asked her why she didnt texted me back. She said that she did and even showed me her msg. and later that dat she sent me a msg. And i got nothing. I tried restarting my phone and even sent a msg to myself. Its working just fine and my other contacts can send me a msg except for my friend. Is It me the problem or hers?
