[Bug] Phone loses mobile connection without notice [answered]
asked 2014-06-23 12:52:19 +0300
Hi all, I'd like to know if anyone else is having the same problem: Every now and then my Jolla loses it's mobile connection (meaning no received phone calls, or MitäKuuluu messages) without it giving any notice about, and it doesn't complain about it at all. The only way I notice this is if I try to send Mitäkuuluu messages it shows that they're not getting through (haven't tried calling while it's going on). It fixes itself after a boot though.
This is really irritating as it means I can't trust that people can call me when they need to, and non-surprisingly my phone is the only way to contact me when I'm on the move.
Well, I can sadly confirm that you are not the only one.
For my own inconvenience I have not been able to repeat the disapearance of the cellural network connectivity in any sane pattern: it so far seems to be completely random.
In my case neither toggling air plane mode, mobile data or 2G/3G/3G connection seem to help. After reboot everything seems to be fine again.
ighea ( 2014-06-23 19:50:32 +0300 )editThere is a hardware (?) problem already reported a couple of times: The SIM card looses connection to the Jolla phone. If the Jolla does re-recognize the SIM card, it asks for the SIM code – but since the March or April update only after the lock-code has been entered. (It seems, there is a minor indication for the user: If the SIM is recognized but the SIM code not yet entered, on wake up immediately the lock code enter screen appears instead of the lock screen.) – However, this type of disconnection does not require a reboot for reconnection.
Do you have the mobile connection symbol (i.e. 2G/3G/4G) when the connection has broken down, i.e. the phone does not even recognize the missing connection?
