SMS gateway services providers usually only support certain protocols and interfaces. This might place a limit on the what, how and where of their products and services.
What protocols and interfaces do these service providers typically use?
HTTP: This is very simple to use and the most commonly supported protocol for sending and receiving text messages. However, it is not very secure. When logging in to an online portal where you have to submit sensitive personal information like your bank account details, service providers will use HTTPS (HTTP + SSL encryption) to ensure your safety. HTTPS encrypts data so your information can’t be stolen online.
XML over HTTP / HTTPS: A SMS gateway services provider will use XML over HTTP / HTTPS for sending bulk SMS messages because it enables the submission of a large amount of SMS messages in a single HTTP request.
SMTP: For sending email to SMS / or SMS to email messages.
FTP: One or more SMS messages are put in a text file and uploaded to the SMS gateway provider’s FTP server. Like XML over HTTP / HTTPS, FTP is a better choice than HTTP / HTTPS for sending bulk SMS messages since it enables the submission of a large amount of SMS messages in a single upload.
SMPP: The SMPP protocol is
– Standard operator GSM interface.
