I am currently in the UK and unable to send outgoing texts. When I try to do so, the circle spins and it says it is sending but always fails (times out?). No explanation. Just a red triangle with an exclamation mark inside. I have tried to send texts to Koodo at 5242 to get a text plan as well as to a regular using the international format for calls to North America. Any ideas what in causing this and what I can do about it?
