Sonetel market themselves as a "global phone system".
Quote from customer support:
"Please note that UK mobile numbers has international reachability issues when you try sending a SMS from an international number."
Then what on Earth is the point of offering these numbers if they can't receive SMS from anywhere than the UK........?
"However, US numbers can receive SMS from any mobile phone."
No, I tried, the USA mobile numbers marketed as able to receive SMS-to-email cannot receive SMS from Australia (Or Whatsapp even, which is in the USA........) so they're wrong.
Calls fail 20-30% of the time.
