sms transmission speed


Approx how fast SMS transmission can one expect when using M1306 which is Not continuously connected via GPRS ?

Wikipedia says GPRS modems maybe be able to achieve up to 30 SMS /min.
While some other pages put it at at 10 / min.
Where does factor 3 difference come from, was Wikipedia number possibly obtained by sending SMSes via continuously connected GPRS connection, while in other test modem was possibly not continuously connected and having to establish GPRS protocol for every single SMS added some extra time ?

Sources: … sms-modems
“These modems will send/receive around 10 messages a minute.”
“If SMS over GPRS is used, an SMS transmission speed of about 30 SMS messages per minute may be achieved”
