Good afternoon to everyone ...

Anyone know how many SMS SMS Tool 3 can send per second with a single modem?


Thanks in advance!

Sending of single SMS takes about 5 seconds, and it varies by the network. First SMS takes more time, because the modem is initialized, but continuous sending is something about 4 seconds / SMS. With some improvements to the code the sending time will be about 1 seconds / SMS, if a modem is good.

And how do you comment on this improvement?

Some discussion around the improvement is in this topic: fast sms + queues.

A version which includes changes is not yet released.

Are you using smstools3 currently, and with how many modems, and with how many messages per hour per each modem?

I have clients that can send up to 80 thousand per month ...

I'm just using a modem (yet) but it is why I have not had high volume, but I want to be ready when the solution to achieve this volume of mail ...

With 80000 SMS per month, time for single SMS is about 30 seconds. If the numbers of recipients are not generated by random, single modem should handle this volume. If there are numbers which are not existing, that of course causes delays, and breaks the "fast" sending mode. Also, if some number of SMS are received, and/or status reports are used, reading of them takes some time, but not much.

In many cases it is wanted that SMS is sent when people are awake, or even during some certain hours, like just before lunch, as for example. This causes that much more capacity for sending is needed, like 32 modems or even more.
