        @Aloys said in Mobile Data Not Working:

        how do you delete APN settings when you have no SIM card? in that case, the cellular menu is empty, it only says "no sim card".

        Try with SIM in then, reset all APN, power off, power on.

          Can you try just setting the data part of the apn up and see what happens, no mms settings.

                @Aloys Now i'm on focal on my Volla and all goes well with one APN for internet + MMS on SIM 1.

                Before on Xenial, i used two different apn's on SIM 1 :

                For Internet :
                Name :Bouygues MMS
                apn name : mmsbouygtel.com

                For MMS :
                Name : Bouygues MMS
                apn name ; ebouygtel.com
                MMSC : http://mms.bouyguestelecom.fr/mms/wapenc
                Proxy : 62.201.129.226
                Proxy port : 8080

                You can make tests on SIM 1 and SIM2 because i don't know / use your phone.

                  Thanks @domubpkm , I try on sim1 and sim2 but nothing change!

                  I try my sim card on my old FP2, and mobile data works directly without any change in parameters.
                  I then check that I have same parameters between FP2 and FP3. And it does not work on FP3.

                      @Aloys When I installed xenial UT on my Volla a long time ago, I didn't have internet. The problem was this:
                      https://github.com/ubports/ubuntu-touch/issues/1657
                      This is just for information or food for thought.

                        I have a look at it. It brings me to get information from ofono on my FP3+:

                        phablet@ubuntu-phablet:/usr/share/ofono/scripts$ ./list-contexts
                        [ /ril_0 ]
                            [ /ril_0/context1 ]
                                Name = Bouygues Telecom
                                Active = 0
                                Preferred = 1
                                Type = internet
                                Protocol = ip
                                AccessPointName = mmsbouygtel.com
                                Username =
                                Password =
                                AuthenticationMethod = any
                                MessageProxy = 62.201.129.226:8080
                                MessageCenter = http://mms.bouyguestelecom.fr/mms/wapenc
                                Settings = { }
                                IPv6.Settings = { }
                        
                            [ /ril_0/context2 ]
                                Name = MMS
                                Active = 0
                                Preferred = 0
                                Type = mms
                                Protocol = ip
                                AccessPointName =
                                Username =
                                Password =
                                AuthenticationMethod = any
                                MessageProxy =
                                MessageCenter =
                                Settings = { }
                                IPv6.Settings = { }
                        
                            [ /ril_0/context3 ]
                                Name = IMS
                                Active = 0
                                Preferred = 0
                                Type = ims
                                Protocol = ip
                                AccessPointName =
                                Username =
                                Password =
                                AuthenticationMethod = any
                                Settings = { }
                                IPv6.Settings = { }
                        
                        [ /ril_1 ]
                        

                        then the same on my old FP2 with same sim card, and with mobile data working correctly:

                        phablet@ubuntu-phablet:/usr/share/ofono/scripts$ ./list-contexts
                        [ /ril_1 ]
                        [ /ril_0 ]
                            [ /ril_0/context1 ]
                                Settings = { Gateway=100.89.218.180 Method=static DomainNameServers=62.201.129.202,62.201.129.201, ProxyPort=8080 Interface=rmnet0 Proxy=62.201.129.226 Address=100.89.218.179 Netmask=255.255.255.0 }
                                Name = Bouygues Telecom
                                Preferred = 1
                                Type = internet
                                Username =
                                Password =
                                Protocol = ip
                                AuthenticationMethod = chap
                                AccessPointName = mmsbouygtel.com
                                MessageCenter = http://mms.bouyguestelecom.fr/mms/wapenc
                                IPv6.Settings = { }
                                MessageProxy = 62.201.129.226:8080
                                Active = 1
                        
                            [ /ril_0/context2 ]
                                Settings = { }
                                Name = Bouygues MMS
                                Preferred = 0
                                Type = internet
                                Username =
                                Password =
                                Protocol = ip
                                AuthenticationMethod = chap
                                AccessPointName = mmsbouygtel.com
                                MessageCenter = http://mms.bouyguestelecom.fr/mms/wapenc
                                IPv6.Settings = { }
                                MessageProxy = 62.201.129.226:8080
                                Active = 0
                        

                        I have no competencies on ofono, but I see a difference which seems to me abnormal:
                        For [ /ril_0/context1 ] on FP3 and FP2, it corresponds to the APN setting I have configured and activated, but Active = 0 on FP3 and Active = 1 on FP2. And another difference is that Settings is empty in FP3 and filled in FP2.

                        Thanks of lot if someone has an idea of what to do, for example is there an ofono script (in /usr/share/ofono/script) with which I could try a re-initialization or configuration?

                          I had the same issue some weeks ago with my FP3+ on stable Focal with Free operator in France.

                          I suddenly lose data connection without any event or explanation. Before that it was perfect. After, data was available for about 30 sec after reboot and then get lost. I tried so much things I can t remember. Maybe some of you may remeber that period in the French Telegram group...

                          I reset the apn, did reboots on diverses manners, changed sim slot, changed sim card, wipe phone to reinstall various images (xenial, focal, stable, dev...), switch back to android (data worked!) and back to UT (no data again!), tried a ton of stuff in the terminal thanks to support from the French community, etc. Nothing ever worked for me!

                          After about 1 month I remembered some advice from the Fairphone tutorial. When you reinstall Android, you have to do it without a sim card in your phone. I never did that to install Android or UT and never had a pb.

                          But that time I did reinstall Android without a sim card on the phone, then put the sim and tested data connection, and then reinstall UT without the sim and... That time it worked! So that might be the solution for you also.

                            Here is the link for Fairphones. I think it is pretty clear but if you have questions I can help you from my experience.

                              Thank you @RedXXIII , I will try as you propose to reinstall Android (without sim card) and then UT.

                                Before re-installing Android and UT, I did a few test by launching some scripts in /usr/share/ofono/scripts:

                                • disable-gprs
                                • enable-gprs

                                then

                                • disable-modem
                                • enable-modem

                                But it did not bring back the mobile data !

                                When I enable mobile data, I often notice but not always, that network icon (use for wifi) was flickering between three dots and empty. After the scripts disable-gprs/enable-gprs, the tree dots appears a longer time, I take a snapshot:

                                  @Aloys did you checked if cellular data work for 2G/3G only ?

                                      @Aloys it was the same for me. Is anyone knowing why the icon says 4g on the menu but no connection at the top bar?

                                        Since on my old FP2 (16.04 OTA 25), mobile data were running perfectly, I reinstall 16.04 OTA 25) on my FP3+ (which was with 20.04 OTA 3) and mobile data are working!

                                        So I think we can suspect a regression in 20.04.

                                        so try to find the scenario:

                                        • I was with my FP3+ on 16.04 OTA 25 and french operator "Sosh" (SIM1): mobile data OK
                                        • I switch to 20.04 OTA 2, then 3: mobile data ok
                                        • I change operator to "Bouygues Telecom" (switch "Sosh" in SIM2 and put "BouyguesTelecom" in SIM1): mobile data KO on both SIM1 or SIM2.
                                        • then I had only "Bouygues Telecom" in SIM1, and I never succeed to make running mobile data
                                        • finally switch back to 16.04 OTA 25 -> mobile data comes back.

                                          Then on FP3+, I switched to 20.04 stable channel and upgraded. I have now OTA 3 and mobile data are working. I see that I have the exact same APN settings than with 1604 OTA25.

                                          So the problem is with default apn settings when reseting them, they are:

                                          • OK on 16.04
                                          • KO on 20.04

                                          Problem solved for internet, I need to enter manually the APN settings.

                                          I will give the details of the settings in a next post.

                                            The NOT working APN settings, which are given by reinit of settings, in 20.04 OTA 3:

                                            The working APN settings, which are given by reinit of settings, in 16.04 OTA 25:
                                            Working_APN_settings_resized.png
                                            In 20.04OTA3, I erase the two default not working settings, and create two new ones equal to the ones of OTA 25. I reboot the phone and enable mobile data, it works!

                                            Problem solved for internet!
                                            not yet for MMS! probably APN settings are incorrect, I would need to set MCC, MNC, APN type as it was previously mentionned here: https://forums.ubports.com/topic/5615/how-do-you-set-the-apn-settings-for-mcc-mnc-and-apn-type?_=1701009468487 but this post does not help so much.

                                            How can we manage these settings MCC, MNC, APN type within UT?

                                              @Aloys I think you will have to test for yourself to find the right Bouygues apn's on the FP3. But your screenshots suggest that you need 1 apn for internet only and the other for mms only. I gave what worked for me.

                                              And no, MCC, MNC, APN are not parameters existing under UT.
