Thailand SMS Features and Restrictions


Thailand is a very large and rapidly expanding SMS market that has many filters in place; direct connections are necessary to ensure SMS delivery to all networks.

We have adaptive routing in place, which combines several routes and chooses the best one to ensure your message is correctly delivered.
