I cannot send international texts from my iPhone 4. It worked fine with my NZ SIM card, but since signing up with koodo they are not received. I have all my numbers as + int dialing code and have tried using 011 int dialing code but still no joy. I can receive texts from and can make phone calls to these number. The companies are listed as being partnered with koodo. Can anyone help, koodo help has not been very helpful.
