• Sonim XP3-Kashering, Tips, Tricks And Buying Guide

chaimontherun Yes, I've researched it as well, it is not available for ATT. There are many small differences between the two versions

      chaimontherun Interesting, I can't say I tried every app, but anything I tried from apk pure or elsewhere only worked with adb

          Techgen I just wanted to add that you can also restrict factory resetting the phone with the built in restrictions app.

              Techgen Yup, your correct. I found this on the web:

              The phone supports voice-over-LTE on both AT&T and Sprint, and Wi-Fi calling on Sprint. It has HD calling, but not EVS. (EVS, which offers even better call quality than HD calling, requires a much higher-end modem.)

                Techgen Yes, but there may be a way to reset the phone even if its blocked through the built-in app. You must go to "restrict features" and restrict "security" also.

                    chaimontherun Yes, I understood what you meant, I was just saying that also things not from apkpure didnt work. I looked at the page you linked, they say that they specifically signed it with a sonim signature so it should install on the sonim, so it makes sense that only that worked directly from the phone. [not sure about the update...]

                        chaimontherun I havent tested it, but whatever works. The option to block factory resetore is also in restricted features section

                            Techgen Yup. Right under that check off the box to block security other wise there may be a loophole to reste the phone.

                              I have updated the guide with instructions on how to test the phone.
                              If there's anything else you'd like to see added to the guide drop a comment below.

                              anonymousflipphone Indeed, it is not too difficult to get around the Sonim Safeguard. It took me about a day. (I'm not trying to show off, I'm just pointing out so that וכל העם ישמעו וייראו).

                                chaimontherun (This will remove Wi-Fi calling as there is a loophole through that package-simply removing the browser will not do the trick)

                                What does that mean? You have to remove wifi calling in order to disable the browser?

                                    cowculator There is a loophole that you can browse the internet thru a page in WiFi calling, even if the browser is removed.

                                      Yes, but it seems you can't really go anywhere past the Sprint website.

                                        4 months later

                                        Can you post information on removing the radio, and is there a way to see a list of apps?

                                          You can press the menu key while in the main menu and select 'mange apps'.

                                          is it possible to block the uninstall updates? uninstalling the safeguard update automatically resets it
