Hi,
we have used for long time SMS send tool with 2G/3G modem, but now some customers report unwanted cost drag from SIM credit.
Finding a solution we discovered that “delivery receipt” was send by the router for every SMS, the operator (TIM Italy) told us that this feature was controlled by the phone/modem, they do not enable by default.
As we do not have this problem before, i think this is a bug by latest version of RouterOS (6.41.3 actually), nothing found searching manual/website/forum, so i can’t miss some setting (very few and simple for SMS).
Can anyone help to find a solution? It will be possible that RouterOS add *N# to the beginning of the SMS message?
thanks
Federico
