Fixed Galaxy S7 APN issue

galaxyowner7

    I bought a Samsung Galaxy S7 Active through AT&T and switched over to T-mobile. I unlocked my phone and everything worked for about a month. All of a sudden my phone stopped connecting to internet off Wi-Fi. My phone still made calls and sent and received texts, but the data wouldn't work. I made sure my data was turned on and tried restarting my phone, and even did a factory reset. Still didn't fix the issue. I called T-Mobile for help and they reset my APN info back to their default, but it still didn't work. They ended the call by basically sorry we can't help, sometimes phones from other carriers default back to the original carrier and there's nothing we can do to fix it. THIS IS COMPLETELY WRONG. Here is the solution.

    1. Go to Settings>Connections>Mobile Networks>Access Point Names

    2. Click on each name and in the top right corn click the 3 dot menu icon and click Delete APN. Delete ALL of them.

    3. Restart your phone.

    4. Repeat step 1 and go back to Access Point Names.

    5. Click ADD on the top right and fill in the APN information exactly like this: Network, APN, and VoLTE: Samsung Galaxy S7

    6. Click the 3 dot menu icon in the top right corner and hit SAVE.

    7. Go back to Access Point Names and make sure your new APN is selected.

    8. Restart phone and Voila! Your data connection should work again!

    You're Welcome.

        Does yours work in areas with only Band 12?

          I can verify this fix works!

           

          I had a Samsung S7 Active unlocked from AT&T with this same exact issue. I called T-Mobile support and they had me go through all the debug steps - New APN entry, clearing cache on my browser, clearing storage on multiple apps on the phone. None of it worked. I stumbled across a work around on my own - turn airplane mode on, wait a few seconds, and then turn it off. Data would come back every time. But only until the next reboot when I would lose it again. These steps provided here in the OP work as a permanent fix. Data is on every time after a reboot. Thanks for posting the fix! I only wish that the T-Mobile tech had thought of this.

           

          Before I deleted all the existing APNs, I noted that there were about a dozen of them on my phone. My theory is that the S7 is not defaulting to the correct APN for the T-Mobile network - even after we add a new one and select it as the new default. So on reboot, another one of the APN configs is probably being used from cache, and that's why we are seeing this issue. The new default config created by following the T-Mobile knowledge base article in the last comment is loaded when turning data off and back on again with airplane mode but for some reason is not loaded with a reboot.

           

          When we delete ALL the APN configs save the one, correct config for t-Mobile, then the phone has no option but to load that config at reboot.

           

          That's my two cent theory and I'm sticking to it!

            Re: Fixed Galaxy S7 APN issue

            On the APN Type make sure is not set

            like this:

             

            APN type: not set

             

            I had put in Internet+MMS and my data was still not working, I delete it and now its set on to not set. This work for me, also following what galaxyowner7 said.

             

            Hope this helped as well!

              Wow, this worked! I've been having this problem for months! The settings you linked did not work for me, however. The following settings, however, worked like a charm:

               

              Name: T-Mobile

              APN: fast.t-mobile.com

              Proxy: Not set

              Port: Not set

              Username: Not set

              Password: Not set

              Server: Not set

              MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc

              Multimedia message proxy: Not set

              Multimedia message port: Not set

              MCC: 310

              MNC: 260

              Authentication type: Not set

              APN type: default,supl,mms

              APN protocol: IPv6

              APN roaming protocol: IPv4

              Turn APN on/off: APN turned on (this is grayed out)

              Bearer: Unspecified

              Mobile virtual network operator type: None

              Mobile virtual network operator value: Not set (this is grayed out)

               

              The key, as you say, is to delete the other APN settings completely.

                Ive been having the same issue as well, this is the only solution that worked for me except the part that says APN type:

                I typed Internet+MMS and it wasn’t workin. When I delete it, it worked like a charm!! Thanks alot for this solution

                  So I had this same issue, deleting all the access points and then deleting APN type really worked!

                  Here is the link to my screenshots so you can see exactly what I did. (Its Google Drive so no viruses I promise )

                    Re: Fixed Galaxy S7 APN issue

                    WORKS.  But add a name above the apn.

                    5. Click ADD on the top right and fill in the:

                        name (i just used two letters, it would not let me save the apn info without it)

                        APN information exactly like this: Network, APN, and VoLTE: Samsung Galaxy S7

                    6. Click the 3 dot menu icon in the top right corner and hit SAVE.

                     

                     

                    Thank you so much, I was getting very flustered after hours of searching for fix.

                      This actually worked perfectly after a very frustrating call and a possible trip to a store.  Thank you SO much.  I had the exact same issue and this solved it.

                          Re: Fixed Galaxy S7 APN issue

                          Again, the above solution is great, except for one problem that I cant seem to fix.  I can not send nor receive pics on text messages.

                          I did try adding MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc  

                          It cuts out the LTE connention and I have to remove  it.

                          Any ideas and help would be appreciated!

                          Thanks in advance....
