I've been having some trouble with receiving text messages the past couple of days. I can send and receive texts from everyone except for one person. When I send him text messages he receives them and when he sends me text messages they don't go through to my phone. We both have Samsung Galaxies, he has the S2 and I have the S4, and we're both on Koodo. How can we fix this problem? And before you ask, no, my texts aren't being ignored. I'm currently using Facebook chat to talk to this person because text isn't working lol.
