Error: 15 No route defined for this message

[Pepepy]

When I execute the code I receive the following error message:
15
No route defined for this message

What could be the cause

`from clockwork import clockwork

api = clockwork.API('MY_API_KEY_HERE')

message = clockwork.SMS(
to = '3411111111',
message = 'text menssage',
from_name = 'Name From')

response = api.send(message)

if response.success:
print (response.id)
else:
print (response.error_code)
print (response.error_message)`

'3411111111' may be this number not available for this api...
