# Troubleshooting phone/network/SIM problem

I find myself, for the third time, having trouble with my phone. It was replaced last year completely, after just under a year of the warranty after an earpiece/speaker issue, which it had been back twice for. Now I'm having regular problems with the phone finding the network/ I assumed at first it was the SIM card (o2/Giffgaff) and got a replacement SIM, which at firest seemed to be better, but it was not to last.

Now I'm regularly finding it is unreachable, I've tried everything, swapping the sims makes the Jolla still unreachable, not possible to connect a call from another phone, and on the Jolla in networks, it states either 'Oops no networks found', with a pull down search just going round and round, and under select network automatically it just reads ' network searching'. or it might read 'network denied', and then five minutes later, I can phone it, and textes come through! I've seen the display show 'disabled' under networking, phoned it, and it's changed to 'enabled' and rang ! Sometimes it lasts the day, or at least i think it does, sometimes it's off again by morning : /

And I have no way of knowing just how long it will 'last' when it finally connects, it is sporadic at best, annoying as sh*t by the hour. I have two phones and have now had to resort to telling people to ring me on the other number if they can't get me on the 'normal' number, which embarassingly is an unfailing cheap WINDOWS phone ! I have not changed any network settings, which have worked since I first got the phone, so in my mind the fact that putting another working sim in the Jolla and getting the same results . . . . . . surely suggests the phone is faulty yet again?

Is there anythig else I can try to troubleshoot or am I just wasting my time and should crack on with sending it back?

For me looks like a HF issue. What about the network strength indicator? Is this problem present anywhere, did you move the phone in another cell? The phone isn't covered in microwave shielding material? (In old times I once had a phone with replaceable covers and tested a chrome-plated one... very nice, but completely senseless.) Ever tested with roaming activated?

In terminal, what's the output of the following?

devel-su
btrfs fi show


If it says 'size 13.75GiB used 13.75 GiB', you need to remove (a bunch of/big) files/applications to free space, and afterwards use the command 'btrfs-balancer'.

@nthn thanks for the reply, it shows 13.75gb as stated but only 7.75gb used, and I know I've not had a lot of files per se on it stored as I tend to remove stuff ssh'ing into it (photo's etc) and app's wise I've got a few but with 6gb spare it looks like space is not my issue.

Does rebooting help? After rebooting the phone, does it stay connected for some time, before the issues begin? Is it a battery connector issue? If the contacts between the battery and the phone are corroded or not firm, then whenever the radio tries to draw power it could cause issues - if so, the folded-paper trick might help. In general, though, I would say "contact Jolla Care" for this issue.

Have you tried as a test to set "prefer 3G"?

There are several issues reported on this, added a list in the comments here: https://together.jolla.com/question/126545/4g-data-fails-connect-workaround/
