What are the restrictions when sending messages to Ecuador?

When sending messages to international destinations text messages can be subject of local restrictions/filtering imposed both at government and local network levels. Unfortunately we cannot influence these decisions so in order to maximise the potential of a successful delivery please follow the regulations. We have listed known restrictions per country but please note that these are not exhaustive and can change as new restrictions are applied – in most cases the local networks do not make notification of changes, we will update restrictions as and when they become known to us.

The information provided by our network providers states that the following originator behaviour per mobile network:

Movistar Ecuador – Originator overwritten with short code (Note: a short code refers to a five digit number)
Conecel – Originator overwritten with short code
Alegro – Originator overwritten with long number
