# [Xperia X] Loss of mobile network

Tracked by Jolla

Sometimes my Xperia X finds itself not connected to the mobile network even if the network is present. The only way to recover from this situation appears to be to activate and then deactivate flight mode. This is a different issue from the Jolla C one where calls are not available since in this case the phone displays no network available.

same here. sometimes its enough to just change e.g. 3g preferred to 4g preferred but its annoying

Short version: I think the network stack is broken in Sailfish. Hopefully Jolla has the skills and will allocate the needed resources for fixing this critical part of a mobile device.

Longer + rant: My experience with cell network management/coverage/recovery Jolla devices was and is awful. Things went from bad to worse at 2.0 update (around dual sim support addition time). This is by very far my main concern with the phone.

What I have seen on both Jolla1 and JollaC:

• network search is VERY slow (sometimes minutes when standing still) and unreliable. When on move and bases change continuously, it's a nightmare
• available 4G is often ignored - I have to go manual search (minutes...) to force it.
• sometimes it can stay for minutes with "no network available" in areas with good coverage
• the infamous "No voice ... restart the phone"

These issues have been reported so often and all we got is that embarrassing "restart your phone" workaround.

I was in doubt on who to blame: the modest hardware in Jola1 and JolaC or SailfishOS itself. Given your post related to XPERIA, it seems to be SailfishOS (ofono?ril?), so upgrading to XPERIA won't solve my main problem. XPERIAs pack good hardware. Past experience shown reliable cell connectivity. I don't own a F5121, but reviews are good on the matter.

I start wondering if Jolla owns the engineering knowledge to address these issues at all (this may sound insulting, but it's not my intention - I know skilled engineers in this very narrow and specialised area are not legion)

Whichever at work between lack of skills and/or interest in allocating resources for fixing the basic features of a phone, the result is unreliable network. Unless you live hooked on a bird-frying 4G base. If the latter is the use-case considered by Jolla, I won't see a fix anytime soon :).

today there are much less problems with mobile internet

@NuklearFart: I have not noticed any recent mobile network improvement on my say - 2-3y on Jolla1 or since 2nd batch of JollaC has been dispatched. I sincerely hoped it's the hardware, and that XPERIA +SFOS would match Android in this area.

Thank you for all the reports. Could you also mention the country you are in and the name of your operator if you experience this problem?

Russia/Moscow, Megafon. It happens mostly on exit from subway.

Germany / O2 --> Your APN Settings are wrong. You took them from the prepaid version, not from the tariff. Internet worked almost fine the last days, today I had to switch modes to get it up and running again but I had that issue also with that bulk of droid sh*t. Might be something with the coverage :D I think about changing my provider.

Same thing happens to me. I am located in Switzerland using Sunrise or Swisscom as a provider.

BTW, also happens just with wifi connections and the contact sync with google just vanishes at least once a day.

I have had the same situation: Lost mobile connection and never reconnected. This happened 4-5 times in the last 4 days. Toggling the Airplane mode or even restarting the device did not always reconnect the device to the mobile network. For me, the fastest way to reconnect the device is starting up the terminal (developer mode needs to be enabled) and executing the following line:

devel-su systemctl restart ofono


The device reconnects immediately after entering the root password. Do not ask me why a restart of the phone does not always help in my case, as I would have assume it properly reset and restart the ofono stack

Thanks, this works for me.

Could it be the bug is eliminated with 2.1.4.14 now? No connection loss since upgrade ... that means I just need only ONE phone carrying around from now on... happy dancing

( 2018-03-11 09:36:22 +0300 )edit

No, it happened several times to me since I upgraded to 2.1.4.14.

also roaming is very very bad!

I was in Turkey this spring, and I had a really hard time to get the phone working at all. There were three available, Vodafone and two others, but I had to reboot, search for networks and in the end force the device to 2G only in order to get the SIM pick up any network at all...

I've had the same problem every morning. Before I go to bed everything works fine but when I get in the car and start my drive to work in the morning I have no network connection. I also see a star or some other symbol inside the wifi icon at the top. Simply rebooting the phone gets everything back to normal. While it's annoying the very fast bootup of the Xperia X negates this being a huge problem for me.

@Desmo: Please update to 2.1.3.7. Any better?

( 2017-11-15 12:05:59 +0300 )edit

I don't have these problems at all with my APN settings. The only issue I have now is periodically the timestamps on messages stop showing up after sending or receiving an MMS. Deleting the messaging thread remedies it on next message. Telephony has been rock solid otherwise.

Updated to 2.1.4.13 yesterday, hoping that this issue is solved. But nothing changed for me. If network gets lost once, there is no automatic reconnect. I need to go to airplane mode and back to get back GSM connection. Sometimes only a restart helps :/

How is your experience with recent update?

Same problem in Finland, Elisa/Saunalahti. At the moment the problem occurs after every reboot. No indication of available network. Flight mode toggling on/off resolves the situation in appr. 30 secs.

Version in use: Sailfish X, 2.1.3.5. I have not encountered the problem with Jolla 1.

@TomC: Does this issue keep occurring after updating to 2.1.3.7?

At the moment, with 2.1.3.7, the 3G network becomes available in less than 5 seconds after PIN code entering. After I posted the answer on Nov 8, there were also reboots with 2.1.3.5 when the network became available this quickly. What I didn't notice then, that I noticed just now when rebooting three times in a row, is that after becoming available quickly, the network is disconnected after appr. 20-30 seconds and stays disconnected for 30-60 secs. After that, the network is restored automatically and stays restored. In other words, I don't need to do any workarounds now. But I can't tell if this temporary dropout behaviour occurred on 2.1.3.5, as I never monitored the connection accurately after reboots..

im on metro pca and when i change it to prefer 3g it loses connection, so i leave it on prefer 4g.

Today I had to set the XperiaX in airplane mode and lateron in normal mode again. After that the mobile network did not function anymore. No calls, sms , no internet possible. Tried to follow instructions from Jolla website. Did not help. Contacted the provider, but they could not help me either. I have the latest update (last week). What can I do?

( 2018-02-23 23:01:08 +0300 )edit

Sounds like a damaged SIM card. Have you tried cleaning the contacts of the card? Does the card work properly in another phone?

( 2018-02-24 10:13:12 +0300 )edit

I have the same issue. Xperia X (SF 2.1.4.14) loses connection after restarting in a few minutes. I'll try to shed some light on the issue in my case. Here are the facts that I gathered while investigating.

When I'm sharing internet connection from the phone the connection stays longer on when data is transferred eg. YT video or even setting up ping.

When nothing is transferred and the phone is left on its own after a few minutes it seems to auto-disconnect from the network.

The connection gets back only if: 1. I restart the phone. 2. I switch plane mode off->on (sometimes twice) 3. I restart the ofono service using terminal (also twice)

This is log after restart: The error "Requested file structure differs... " seems to be irrelevant.

I suppose that the problem occurs due to some power-saving mode which makes ofono service fail and when restarted impossible to reconnect. Is there a way to prevent services from freezing? I would do further investigation because my phone is simply unusable right now unless left with Youtube playing all the time.

What should I check now to further investigate the issue?
