SMS sent multiple times even if it was sent only once

  1. Hello,

    I am using Telit’s GL868 Dual modem. I have developed one simple application to send SMS to predefined SMS user(s). When certain condition arise, i wl trigger a sms to one or more than one sms user. It works fine.

    Bt some times, may be one or more than one user(s) will get multiple copy of same message. So where i am going wrong?

    Thanks in advance…

    1. Are you very sure isn’t your application that triggers the doubled messages? If yes, does this happen with other operators; with single recipient and many?

      1. Thanks for ur reply.

        Yes, I have checked in my application is not triggereing double sms, and also I have tested it with 2-3 different sim card.

        As this problem is random, i.e. only few times it triggeres duplicate sms, i am unable to trace the reason.

        1. Hi,
          the only way to see if module send more than one SMS is to collect a trace (if it’s possible) of the module with our RTD tool (if you don’t have it you can download it from this link:
          RTD) enabling Call_SMS template.

          Thank you.
