There is mobile number. Why is Sender ID?
If you run a SMPP connection you could have a short number or alpha numeric number this is where its used.
hi guys im new here to playsms what i dont understand is that SMPP do i have to get from my carrier or how becaus i dont understand it?
If you use gsm sim cards, you have to use gsm modems. If instead, you have a direct connection to your carrier, you can ask for a smpp connection, or a http one. Then, you can use, e.g. kannel to conect playSMS to your carrier, through SMPP connection
edilson thnx for ur reply ive asked my carrier but they dont give smpp user and password so i wanted to ask is any other option for a smpp connection?
SMS carriers like infobip, nexmo and alike provide smpp accounts. Traditional mobile carriers don´t. You have to use usb gsm modems or others, like GoIP to send sms
