Lost mobile data after upgrading to Android 6

[Mairsil]

I installed the Android 6 update on my Z5 Compact yesterday, and since that time mobile data is no longer working.

• I've tried rebooting to no avail
• Internet works fine when wifi is enabled
• Phonecalls work fine, and I have full bars or near-full bars most of the time.
• I am connected to the correct provider
• Mobile data is enabled, and the mobile data limit is disabled

There is no mobile data icon showing in the top-bar, and chrome is showing I am disconnected ("ERR_INTERNET_DISCONNECTED").

Any ideas on what else I can try to get my phone connected to mobile data again?

Hello,

yesterday I got a new Z5 compact and use my old SIM-card from my Z3 compact for the new device.

I connected it to my WLAN and made an Upgrade to Android 6. Did not try the mobile internet before this upgrade.

But Today I disconnected the device from my WLAN and no mobile connection is working...

Following steps I allready tried:

1. Download Internet settings again - download and installation is shown as completed, but no mobile connection is working (reboot done)

2. Tried to send the SMS for internet settings manual from the provider-side (o2) - I got a SMS with the error message, that my request could not be fullfiled...

3. factory reset the device with step 1 and 2 again ... no connection

normal calls works fine, also internet connection over WLAN... the SIM-card and the mobile internet-connection works fine with my old Z3 compact - I tried it just 30 minutes ago

Could you help me please? Would be sad, if I have to send the device back... I like the Z5.

Thanks a lot

Best Regards

Same issue with my Z3 compact after upgrading to Android 6

I got it.

After reseting the mobile phone, I did not try the phone-Intern link to download the internet-settings and downloaded the settings via sms (started from the official side of my mobile provider).

Worked fine. No idea, what goes wrong by downloading this settings with the phone-intern link...

hope, this will help others

Similar issue here.

After updating my z3 tablet compact lte, mobile data is simply missing. Device does not ask for PIN upon reboot, and more - Internet settings isn't in the menu. I downloaded an app and tried toggling mobile data off and on, no response.
