I am Canadian and have a Sony Xperia with a Koodo plan. I added the international text $15 plan. I landed in France and turned on my cell and got the Koodo message welcoming me to France. I was able to make a phone call and I have received a few texts. My problem is that I can't seem to send texts. I get a message saying cannot send message. I rebooted my cell. I took out the SIM card and rebooted it...nothing seems to help. I don't know if Koodo needs to do something on their end? Please help.
