Fixed Galaxy S7 APN issue


    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


              Proxy: Not set

              Port: Not set

              Username: Not set

              Password: Not set

              Server: Not set


              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.

                          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:  

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

                          Any ideas and help would be appreciated!

                          Thanks in advance....

                                        Hi, I just switched to t-mobile yesterday and have spent more than my fair share of time trying to figure out why I have no data. I was with customer service for way too long and they pretty much told me after two hours to go to the store to see if the problem was the sim card or my phone.

                                        I had a perfectly working phone yesterday, so I'm struggling to believe it's  my phone.

                                        Anyway- I have played with the Access Point Names for about 3 hours now and I FINALLY think I'm set. I have data!

                                        So do not give up- because no internet is sheer BS.


                                        I'm so thankful for this thread.


                                        They key for me was: DELETE ALL ACCESS POINTS. Edit or Add ONE of THEM to the LINK Provided above in the forum. Play with everyone's suggestions as to the APN type. The one that worked for me was "Not set"


                                        So this is what I have


                                        T-Mobile US LTE










                                        APN Type

                                        Not set

                                        APN Protocol


                                        APN Roaming Protocol



                                        Then Turn your data off and on again.


                                        RESTART YOUR PHONE.


                                        You should be set. If you're not- change the APN Type  to everything possible

                                            Just pulled the switch from AT&T , our Iphones worked immediately, however the Galaxy 7 EDGE phones could not connect to the internet on the network.

                                            performed your fix , and all works well .

                                            Thank you.

                                                  Hi all,


                                                  I had high hopes for this fix, but found that I didn't even have the option of deleting the APN when I went through the settings.


                                                  I have a Verizon S7 that I switched over to T-Mobile, and after hours of effort I simply cannot find any way of deleting the Verizon APN, which I believe is interfering with my new service. I've set up the T-Mobile APN but I hardly ever have any call service anywhere (and I live in a major city). Data works fine, but phone calls constantly fail to even dial.


                                                  I wanted to try removing the previous APN as instructed in this post, but apparently it's not possible with Android 4.0 on Verizon devices. Does anyone have a clue how I can delete the Verizon APN, short of rooting the phone?

                                                          Doing this did NOT work for me and I was experiencing the same problems as OP. But what I did do instead was I turned "International Data Roaming" on and that allowed me to get data. Now I have a feeling on my next billing cycle I will be given a huge bill, but whatever - I am inside US using data I'm supposed to be paying for anyways. So because of this I wonder if the geolocation of the Samsung Galaxy S7 Edge is throwing it off - or something. I don't know.

                                                              If you have ever or know someone who has flashed a phone it can be flashed with T-Mobile software very easily being that T-Mobile did sell the s7 edge if something you would want to do you can go to XDA developers website and find all that is needed to do this just make sure you get the correct version of Odin and the flash file to match your model of phone for example (SM-G930) this will work on both the s7 and s7 edge and can be done with the U or T firmware file and for all who may read this I am working on a file to do the s7 active aa I need it myself and as soon as i can find the right modem file I will post it here all the newer phones like the s8 and s9 they made it easier to debrand or uncarrier your phone

                                                                  Could you let me know if there is a firmware file for an AT&T S7 Active moved to t-mobile.  I'd like to get an active for my wife because of it's longer battery life, but worry about the phone not working with T-mobile network.

                                                                  I read this post plus the second one below.  For my case, with my Samsun S7 active by ATT, I simply deleted all APNs except for T mobile APNs with connections.  I then simply turned on and off the airplane mode and internet connection immediately came back for me.  Good luck to everyone in getting your ATT Samsung S7 actives up and running again.

                                                                    I ported an unlocked S7 Active from AT&T. I had none of the problems described here until I traveled to Canada. T-Mobile claims to provide 4G LTE roaming in Canada. My phone does voice and text fine, but no data whatsoever. I followed the advice above, including deleting all the other APNs. I also spent nearly two hours on two separate calls with T-Mobile tech support. But I still can't get any data in Canada. International roaming was the main reason I switched to T-Mobile. Having to buy a new $800 phone kinda defeats the purpose. Have you had similar problems when roaming? Any suggestions?

                                                                        Have you tried manually selecting the roaming network?  Do you have Data Roaming enabled in the Settings, Connections, Mobile Networks? 


                                                                        Bell or Telus (same network) are T-Mobile's roaming partner for Canada.  AT&T was Rogers and Fido/Chatr (same network).  Make sure the device is not trying to roam on to any of the Rogers networks.  If that doesn't work, try adding the APN's for Bell and Telus but do not set them to the default.  Power off the device for a few minutes, then power it up and see if your data works.
