Hello Eric,

The send time in the log is the time that Diafaan SMS Server sent the message to the mobile network. It is the local time on the PC/server where Diafaan SMS Server is installed. The 'received' time is the time when the message was delivered to the mobile phone. It is the time stamp of the SMS central that delivered the message (or possibly of one of the intermediate SMS centrals).

The time between the send time and the receive time is independent of anything in Diafaan SMS Server, it is the time the message is transferred or stored in the mobile network. The SMS system is a store and forward system, that means that the messages are stored on the SMS centrals in the network until they can be forwarded to an SMS central closer to the destination phone. There is no guarantee that the messages can be delivered to the destination phone within a specific time.

There are two possible explanations why there is a 5 minute difference between the send and the receive time. The most obvious is that it sometimes might take 5 minutes to reach the mobile phone, this can happen for instance if the network is busy, the phone is roaming on another network or if one of the SMS centrals in the mobile network has a time delay when it forwards the message to the destination network.

Another possible explanation is that the time on your computer or on the SMS central that delivers the messages is off by 5 minutes. That could cause a time difference for all messages or for specific messages that are delivered by the affected SMS central.

I cannot understand why this is happening.. Sometimes recieving SMS is taking more time than it should.

Send time: 22.10.2016 21:58:36 (received on 22.10.2016 22:03:51)

Event log are empty except it says the gateway is not on home network but is roaming. (Which is correct. My providor is a MVNO: Mobile virtual network operator). Except for these warnings, the event log is empty.

The gateway RecievePollIntervalTime is set to 2 seconds.

What could be the cause for this?

In advance, thanks for your help.
