I have a 021 number ported to Telecom XT. Why is it so hard to receive SMS from overseas companies (not spoofing sender numbers)?
For example I am trying to activate EchoEcho and GroupMe, but the SMS codes never arrive. The first time I activated EchoEcho on another handset they actually sent me the code via email, and said they had problems sending codes to ported numbers in New Zealand.
Why is it so hard?
