I added international voice roaming and purchased a $15 international text plan. I am now in Auckland New Zealand and I can receive texts from Canada but can't seem to send them. I am using the 001 prefix with my texts. How do I fix this? Using an LG G3.
In case Paul's suggestion isn't working or you have Already done this, NZ's exit code is '00.' Make sure that if you are doing '001' that you're not doing '001 1 450 555 1234' but rather doing '00 1 450 555 1234.' To make things easier, '+' is the universal exit code and your phone will do it without issues if you do '+1 450 555 1234.'
