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.

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 :).

@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.

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.

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..

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?

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