Bulk SMS coverage & pricing

Network coverage and pricing for bulk SMS to over 900 mobile networks.

Sending SMS through an SMS gateway using SMPP (Short Message Peer-to-Peer Protocol) allows your application, whether it's sending SMS text messages to your customers, notifying staff of important information or updating a remote device, to quickly send a message and know when it's been delivered. Secure SMPP sessions are supported using TLS. SMPP is the best SMS API for handling high volumes, reliability and avoiding SMS gateway supplier lock-in.

There are a number of development kits, applications and code samples that can allow you to easily integrate SMS mobile messaging into your application. Our Developer site at developers.hslmobile.com is a great resource to get you started and if you have any questions please don't hesitate to contact our Support team.
