No connection to several website/services via LTE when DUAL-SIM active

[bananajoe78]

Hi,

I love this phone, but one point drives me crazy.
When I have 2 SIM enabled, and logged in to LTE network, I can't open several websites (ex. threema.ch).
When only one SIM is active, all is fine. As well when I'm logged in to WiFi.
As well when 3G is active, all is working.

When I use the phone as HotSpot, I can access the website via laptop.
Therefore the LTE connection is not the problem.
Can someone please try the same with his SIM and report back?

Thanks in advance

BR

I can confirm exactly the same behaviour with LTE over Telekom DE and o2 DE.
Unfortunately, I don't have a solution other than switching on VPN now an then to receive new Threema messages.

Sony recommends to repair the system software (make a backup in advance) via the Companion software, but I haven't tested that yet.

Thanks for testing. I don't think that repair of system software will fix the issue.
I already tried with installing FW from different Region, what is this in principle.
No improvement.

The Sony support told me that the issue also exists for WhatsApp (which I use rarely so I can't really confirm that), so I hope the issue will get a higher priority.
My bug report with Threema's stack trace and so on was forwarded to Sony's dev team. Let's hope for the best.

I get mixed results for wifi tethering. Connected Android devices and an iPhone I tested won't connect to threema.ch, but a Windows 10 notebook does. Can you confirm that?

 

[bananajoe78]

Yes, I can confirm.
I only tested tethering with a Win10 Laptop. Threema.ch was ok.
There are now a lot of messages as well in the Sony support forum.
As well I had issues with streaming from Netflix. But after the update yesterday this wa fixed.
I expect the priority of Netflix is even higher then for Threema

Hi,
Did sony confirm the problem with two SIM?
On the Sony support site, only message from users confirming the problem:
https://talk.sonymobile.com/t5/Xperia-XZ2-Compact/Issue-4g-mobile-internet-with-2-SIM-in-my-xz2c/td-p/1314928/page/3
Local support does not confirm the problem at all...
I hope the problem with two SIM will be fix soon, but for now I don't have any information from Sony that they are working on a fix it
Thanks

Sony confirmed in an email that the issue is also known for WhatsApp and that the support is waiting for feedback from their dev team.
