**** BEGIN LOGGING AT Tue Feb 05 03:00:01 2019 Feb 05 07:03:43 what could be the cause of disappearing sim syndrome? Feb 05 07:03:46 (in n900) Feb 05 07:04:19 to check other sim? Feb 05 07:04:31 dont have any other handy atm Feb 05 07:34:04 KotCzarny: cmt-reset, try that Feb 05 07:34:33 if it doesn't bring it back, let's hope your modem hasn't gone south :( Feb 05 08:00:29 sicelo: i usually enable offline mode then connect via power menu Feb 05 08:00:48 most of the time it works, but today it didnt Feb 05 08:00:53 even after reboot Feb 05 08:01:25 so i took out the sim and cleaned the little pin (and corresponding metal that touches it) on the side of the sim slot Feb 05 08:01:29 and it did the trick Feb 05 09:07:01 at least Feb 05 09:08:41 Can be the contacts of the sim. It usual modem issue is loose connections within the board. I didn't think the sim missing would clear without a reboot. Feb 05 09:15:34 swb: previously it did Feb 05 09:15:45 but this time i had to clean that side contact Feb 05 09:15:54 not the sim pins/contacts Feb 05 09:16:29 might be also coincidence, but the metal part that holds simcard was a bit dirty at that place that touches the sidepin Feb 05 09:28:42 I get dust in there often that can cause it. Normally i just loose signal tho. Feb 05 09:29:20 it looked like some kind of oxidation Feb 05 09:32:51 I think I have discoloured sim tray. Feb 06 00:26:58 Heh, I briefly forgot that the N900 uses a MiniSIM instead of a MicroSIM or smaller. Feb 06 00:36:23 you can use an adapter though **** ENDING LOGGING AT Wed Feb 06 02:59:57 2019
