Twilio 21211 error "not valid number" but it is

I am doing the whatsapp tutorial on twilio page. But when I try to run it gives me this error. The number is ok, the twilio sandbox goes through with the exact same number. Any ideas?

RestException [Error]: The 'To' number +5492xxxxxxxx is not a valid phone number.

thanks.

Twilio developer evangelist here.

If you are doing the WhatsApp tutorial, then you can't send from the WhatsApp sandbox to a regular phone number, you should prefix it with whatsapp:.

Alternatively, I am guessing that your account is a free trial account. Before you upgrade your account you are only able to send SMS messages to numbers that you verify with your account. To solve this, you should verify the number, or upgrade your account.
