The number used started with 06..... not +316........
Updating a firmware is always a great idea, but also a very bad idea in controlled environments. What Frans is asking, is there a list of ACK's and NACK's available? The older firmwares would only respond OK or NOT-OK, the firmware 7.01.2 added the code that the message was split into multiple messages when using rich-text or more than 160 characters. Now we have 1 system that shows the WRONG NUMBER message.
It would be greatly appreciated if you can provide us with the full list of responses concerning SMS in the Teltonika.
Thank you, kind regards, Wybren
