Hi all,
This is a weird one; I've gone through tech. support with Verizon, and they couldn't work it out.
I have a new Motorola Moto X; completely standard, nothing tweaked, works perfectly in the USA. I'm currently in Canada and have been for a week. I can not send text messages; the sending always fails. Note that I have only tried to text US numbers.
However, I can receive text messages from both my wife who is roaming with Verizon on an iPhone 5 (and yes, she has iMessage turned off), and from people inside the USA. I can also make and receive calls.
Truly weird... thanks to anyone who can shed any light on this.
