Sim card deactivates itself

I have the same problem.
And I’ll try to be clear:

  • The sim card is losing connection to the phone. Has nothing to do with unlocking the screen.
    When it happens, and your phone is in your pocket or in your bag or somewhere, you cannot be reached, there are no phone calls coming in nor any SMS’s. Because of the sim card that is locked.
    -This is really annoying, because I usually notice it only after long time, and then a lot of people already tried to contact me…
  • I’ve the impression that it happens when the connectivity to the network is gone. Some places the phone network connectivity is bad or completely gone, and i think it happens on those moments.
  • I was also thinking that it is possible that sometimes the sim card loses connection with the phone, because I’ve a micro sim card that is placed into the sim-card-adapter (provided with the fairphone), maybe with this configuration, sometimes the simcard doesn’t touch the connection in the phone anymore, which makes it loose its physical (golden plate on the si card and the connector of the phone) connection to the phone, and you need to re-enter your pin-code.

So I hope you have enough information to reproduce the bug, and that it is possible to fix it soon.

Thanks

Same Problem since 3-4 weeks, but severeal times a day…eg. today already more than 8 times. I’m looking on my desk, where the ‘old’ HTC Radar is still waiting to be used…
please find e solution - thx

For me the same problem over here! If anyone has the solution, please let me know!

I had the same problem since the “Cherry Pie” update. It might have to do with the reports about an increased touchscreen sensibility and having “ghost tappings” on the screen. Maybe my pocket just reboots the phone.

My personal solution: After three months I just downgraded from “Cherry Pie” back to the previous Fairphone OS “Chestnut” (as I was also annoyed by strange battery behaviour since the update). If this saves the problem remains to be seen. I sure hope so!

Hmm, i’ve no other issues with the newest firmware. I guess it’s my pocket too, which restarts the phone. Because it doesn’t occur very often, i accept the current situation.

Hi!

I have this same problem. After the latest software update my phone seems to randomly loose mobile network connection. Sometimes the connection is lost several times a day…

Sometimes I notice this, because the phone asks for PIN code. Lately though I have just gotten noted by colleagues that calls to me are forwarded directly to the answering service. When this is the case, if I try to disconnet the SIM-card from the SIM management settings, the phone just freezes and the only option is to reboot.

I’m pretty sure it has nothing to do with the touchscreen sensibility, since it also happens when my phone is lying on the desk. I also haven’t been able to find any other reasons for this behaviour. It seems totally random. Sometimes it happens several times a day, sometimes not.

I really love my fairphone, but this is a rather inconvenient problem, since I prefer to be available during the work day…

Same here - really annoing situation! Sim get disconnected and PIN has to bei typed in. Cannot find any solution online. Support is only in english avialable? Anyone tried to get an answer? Normal Sim, First Slot. Seems to fit, Don T think this is a Hardware Problem!

I’ve got the same problem with my fairphone. For me, there seems to be a conjunction between using the bluetooth and loosing the mobile network connection. Someone with the same impression?

Well described! I have the same problem ;( Any idea why this is happening or how we can avoid being without connection?

Thanks!!

I know that other Smarthones have similar problems.
The signal of the wireless network has much more power than the GSM signal.
Also the bluetooth signal is stronger than the GSM signal.
A receiver of a powerful signal creates a (relative) strong magnetic field, and this prevents the reception of other weak signals.
So its possible that when you are on are with your smartphone on a place with weak GSM reception, you can get the signal when your smartphone is in the “normal” mode.
When you activate WIFi and / or Bluetooth, the reception of the GSM signal will collapse and the Sim card deactivates itself.
Sometimes it changes when you move the phone some meters to another place where the GSM reception is better (p. e. away trom a metallic object that is between GSM antenna and smartphone).

I know that my English is not so good, but I hope you will understand where’s the problem (weak GSM provider).

Best regards

I experience the same problem as well (I have FP1U). Have any of you figure out what is happening? I do not check my phone all that often so sometimes I’m left unreachable for a long time and that is very annoying. I experiment with WIFI on/off Bluetooth on/off, but so far I was not able to manually reproduce the problem.

I usually have my WiFi and Bluetooth turned off to save battery, and yet my SIM-card gets deactivated.

I didn’t have this problem before the latest software update and now it’s usually happening several times a day.

Go to Settings -> Mobile networks -> 3G Service -> GSM/UMTS. Choose WCDMA only. After I did this it has been much more stable. It could be coincidental with other stuff (where I’m located for instance), but it’s worth a try.

Haven’t had this issue in forever now.

Besides, I don’t have 3G.

Hmm, is there no possibilty in Android to view why the phone rebooted? LIke the event viewer in windows. i enabled the tasker run log, but there i don’t see any suspicious entries…

I contacted the FP tech support and they think it might be related to old SIMs. Apparently SIM older than 1.5 years do not always play very well with FP. I tried to google it up, but I have not find a single reference to an issue caused by an old SIM. Nevertheless, I will try that and see what happens. Thing is, that it might be very well related to a phone restart. Next time it happens, I will try to hook it with android debugger and run the bugreport to see what has happened.

Hello,

I have the same problem plus som experience with this behaviour.
My prior Smartphone (Huawei y201pro) rebooted on a regular basis, obviously much more often while moving form cell to cell, almost never when it was just lying at home.
I then got a Fairphone. It showed a similar behaviour, except that the fairphone does not reboot, but resets the sim(s), so that you have to reenter the SIM-pincodes.
I then got a new SIM-card as I suspected it might have to do with mit SIM-card being defective. It seems to not have changed anything, the problem remains. for the Fairphone it seems to not matter if it moves between cells or if it is just lying somewhere.
The problem is obviously not related to older/newer sims, as my sim-cards are now both newer than 3 months.
Do the other people here that have this problem use one or two sims?

Easy workaround for the problem is to remove the simlock/pincode-protection, so the problem still occurs, but it reconnects automatically. So you are still reachable after 30 seconds.
Judge for yourself if that is an option for you.
Settings->security->sim-lock

Still the Fairphoneteam should try to solve this problem as it is very annoying.

My simcard for phonecalls which disconnects is very old (years…). The second (data-)simcard inserted is the newer one, but it’s usually deactivated because i don’t use often data services.

In my case the problem is related to phone spontaneous reboots. Today, I managed to spot the issue right after it happened and so I attached the android debugger and ran a bug report. From the uptime I can see that the phone was up for just a few minutes. Also no background apps, freshly booted. I was skeptical with the SIM replacement, but the guy from the customer support insisted…

I will try the hard reset as this is very likely the next thing they are going to suggest.

Usally I´m using only one SIM. To test, I replaced SIM in second slot - error accured. I used two SIM - error accured. My SIM also is years old. Don´t want to test a new one, if others say error still accurrs.

I think, support has to solve this problem. I don´t want to set my SIM without PIN!!! That´s your task, fairphone-guys! Please no hints like. brush the slot, take a new one or something else - it´s a software-problem!

Sorry for bad english :smiley:
