I am in London, UK, and not able to text my wife. I am using a Moto E 2nd gen and purchased the intl text add-on before leaving Canada. I see that intl voice roaming is also added. I can receive texts from my wife (blackberry...Rogers) but I cannot send any texts. I have restarted the phone several times and add the +1 before texting. Nothing seems to work. Please help!
