Not sure if this is a bug, by design or if I’m just the only one with this:
As I use the Xperia 10 III (SF 4.4.0.64) with one SIM only and a SD-card, I don’t need the second sim. So it came to my mind to simply disable the second sim card in the settings menu. Maybe it would save some system resources over time - who knows?
Having both sim slots activated, the first sim icon would reflect the signal quality accurately by showing a solid bar according to mentioned quality (filled low equals poor signal, filled completely equals perfect signal), while there is a grayed second sim-icon indicating that there is no second sim available (or connected), which is also perfectly fine. Left to the sim card icons there is also indicated if the device is connected to a 2G or 4G network, etc.
However, after deactivating the second sim-slot, the menu shows the first Sim still as active (bright dot next to it) but when switching back to the main screen, the indication in the upper right shows just one sim card with a small number ‘1’ in it (which is expected) but the icon looks like the inactive sim slot of the previous second sim (no solid indication of any signal quality). An indication of network type is missing completely and the icon of the second sim doesn’t show up.
And indeed, this is true as I’m not able to receive any phone calls nor can those be initiated.
Unless anyone can explain to me this weird inconsistency, I’d report it as a bug. Would someone of the other Xperia 10 II users here check as well?
Yes it is. I discovered this within my first day using the 10 III and have rebooted some times since.
Just to proof it again, here is what happens right after a forced reboot:
It works fine though:
receiving calls, initiating calls, as well as sms and mobile data works also.
In the mobile network settings it is shown that it connects to O2 network, which is accurate.
The same sim was properly detected in my previous XA2.
I had some mobile network connection issues right after changing to 10 III, which I managed to fix with some trick (can’t remember the details any more) and no notable issues since.
However, after updating to 4.5.0.16, I’m experiencing the behaviour described in this bug report: A working SIM card in slot 1, no SIM in slot 2.
Only slot 1 enabled → mobile network connection does not work at all (only gray indicator for SIM 1 in top bar, connecting to mobile internet fails), but
SIM1 starts instantly to work if I enable the empty SIM slot 2.
Didn’t try rebooting after the update yet, happy to provide logs & do tests if there’s something I should check or try.
I am currently traveling and use a second SIM card. My travel SIM is in slot 1 and my home SIM in slot 2. In order to save battery i usually have the home SIM disabled, and only turn it on every once in a while i.e. to receive two factor auth codes.
When i go ahead and disable the second SIM again it seems to bring down SIM 1 as well. It will not pick up a network again unless i reboot or do a flight-mode cycle.
That is on an 10 II.
Steps to reproduce:
have two SIMs in the phone and both connected
turn off SIM 2
What happens:
SIM 1 will disconnect as well and stay like that
switching to flight-mode and back, and maybe the “network restart” helper bring it back … or a reboot
What should happen:
SIM 2 should turn off, and SIM 1 should stay online … or briefly disconnect and come back on its own
