Text messages - Send SMS - International Messaging Service


You can add true two-way sms text messaging capability to your applications within about one hour. In short, you need to connect to our service using SMTP protocol, authenticate yourself and tell our service to send a text message to one or more international SMS numbers.

Our "60-minute-API" lets you do this quickly. Here is how.

The following tables provide details on how to integrate external applications to a running instance of WIS – in this case – using SMTP protocol. The setup consists of two distinct parts:

Part 1 - Application Setup
You first need to connect to our SMTP server using your UserName and Password. This is done only once and you will need to write a few lines of code for your application. The code is the same as if you wanted to send email using SMTP protocol. Your SMTP server account will use the following details:

SMTP server name
User Name Your user name (the same account you use to login to – for example jsmith)

Email field Description
“cc” Leave empty
“bcc” Leave empty

  • p,c
  • a,p,c
  • [blank] – you can leave the subject line empty – compression will be turned off

“Message” Write the text of SMS message. Please observe the maximum available number of characters for your account (about 150)

When the message is created, send it using the SMTP account as explained above. The message will come to server which will try to authenticate your account. If all is fine, a credit will be deducted from your account and your message will be converted into SMS and sent to the desired destination - ANYWHERE on the Planet.
