I recently (last week) upgraded from a RUT240 that I had used successfully for a year, to a RUT950 because I needed dual SIM capability due to a flaky local mast. I updated to the most recent version of firmware (6.07.7), and manually configured the 950 with all the same settings that I had on my 240 and tested that the SIM commands worked ok, including the switch_sim command. After a few days, the mast went down again and SIM2 kicked in as expected such that we only has a couple of minutes downtime. So far so good! However, since then the 950 does not register any SMS messages sent to it, whether in the format of a command or random text. I have tried sending to both SIM phone numbers, it makes no difference. I can send SMS messages ok, but if I reply straight back to the message nothing registers, see below:
I am loathed to factory reset the unit as it is in constant use, but the remote SMS feature is very useful when I am off-site and would be grateful if anyone has any suggestions, thanks.
