Switching from Verizon to T-mobile with a Samsung S7, MMS issues


    Posting here as it seems to be a common problem that you lose MMS text message function when changing over to T-Mobile from Verizon with Samsung S7. I search through the forum (though maybe its here somewhere), many times on the phone with T-Mobile tech support / Samsung tech support (both mostly useless) trying many different APN settings/factory reset 3rd party messenger applications but no luck.


    Luckily the store in which a purchased my new plan was very helpful. Ultimately these APN settings were the ones that had to be changed to function correctly sending/receiving MMS messages:


    APN Settings required to change from the default:


    APN type:



    APN protocol:



    APN roaming protocol:

          Finally! Thx you. Fixed my MMS issue. Now how did you get your phone to system/software  update after factory reset?

            Normally upon checking that your APN settings are configured correctly you simply have to restart your device and it should work. There are rare cases in which an unlocked device will just not work for MMS and T-Mobile cannot guarantee that all services be functional on unlocked devices. The good news is that this normally only affects MMS and you are still able to use data, talk & text (SMS). I hope this information sheds some light on your situation.

              This is definitely an extremely unpleasant experience. My husband and I both have Samsung S7 from Verizon. We switched to T-mobile in September 2017 and experienced calling/receiving call/SMS issues during the first two weeks.  T-mobile and Verizon kept bouncing us back and forth. We finally escalated the issue to a more knowledgeable T-mobile tech support, he adjusted the APN and everything went well locally.  Last Saturday we traveled to Las Vegas with family. Both of us went through hell again since we cannot call/receive calls and SMS. No wifi calling. The text messages were delayed and sometimes were not able to receive. The T-mobile logo disappeared in the top left-hand corner. All outbound calls either dropped or had such poor quality that no one understood what we are talking, so we cannot even contact customer service properly. All inbound calls went directly to our VM. Every tech support will no worry, they will be able to help us.  They asked us to perform basic troubleshooting steps such as on/off, ##004#, ##21#, or to ask us to change to a T-mobile device which we do not have, when they failed, they then pushed the ball back to Verizon, stating a disclaimer that those were third-party phones, we can either buy two new T-mobile phones or switch back to Verizon. They trashed our trust, wasted our time and efforts. During the trip, including the long wait time to contact a representative, I spent over 10+ hours on the phone/chat to communicate the issue with "zero" result. Can you imagine the frustration between all our family members during the trip? When we passed the Nevada border back to California, both of our phones were back to normal.  We can call/receive calls/send SMS. After reading so many people were having the same issue, I think T-mobile should improve their services and technical support for customers.  It is unacceptable for a customer to travel with disrupted, unreliable national wide service at a location with good coverage as T-mobile advertised. It is also T-mobile's responsibility to resolve this ongoing issue since their store representatives told us at the beginning that as long as our phones are unlocked, we can switch to T-mobile from Verizon without any problem. Until today, we are still waiting for the customer service representative to contact us as they stated. We are traveling to other states very soon, we are so frustrated and debating what we should do. Any feedback are welcome!

                I have many of the same issues.  I placed my order over the phone on 01/26/2018. I explained the make and model of the phones I have and also a Gear S smartwatch.   I was told no problem switching. I was told I needed to by 4 phones to "help" with the port process and also because I still had device payments on 4 of my lines, 1 is paid off.  After receiving the phones Wednesday the 31st, I did as instructed.  I was told to put the sim cards ($25 dollars each) into the 4 tmobile phones they told me I "needed" to buy as temporary phones.  By the way, no sim came for my Gear S.  The phone came up no problem.  I then called tmobile to start the port request.  I did all of that and my Note 8 & my daughter's Iphone 7 started working shortly.  The LG 10, Galaxy S7 & Motorola Z Play all had problems from the start.  After 3 days and multiple techs, I was told to go into a store on Saturday.  I did that yesterday 2/3/2018.  The mgr explained he wished I had come into the store because he would have told me my V10 was not compatible.  He said the most I could ever expect is 2G or 3G and every once in a while, 4G.  He also told me my Gear S will never work because it is CDMA ONLY!  I told him about the "digital" SIM card I was told to order and she no, it will never work. Lastly, he told me my because I had the error message No SIM Card/ SIM Not from Verizon, that my phones were probably locked by Verizon & I needed to call them to unlock the phones.  I called tech support from the parking lot and spent an hour on the phone.  During that call I was asked to call verizon to see if the the phones were indeed locked.  I got verizon on the phone (called from my Gear S on speakerphone) and was able to let the tmobile tech HEAR the verizon rep explain that not only were my phones unlocked, but that verizon DOES NOT LOCK PHONES.  The rep stated they are only locked "financially" if the customer does not pay the final bill.  The Tmobile tech heard all of this!  Therefore, he had no choice but to determine my phones were simply not compatible and nothing to do with APNs, cell towers etc.  Be careful:  if you have a sticky situation it sounds like tmobile is going to try and use "your phone must be locked by your carrier."  Anyway... it is now Sunday & I have tried calling again for a different solution. I got someone name Fe, she tried desperately to call verizon to check again if my phones are locked. After some back and forth I got over to customer care to investigate getting replacement phones ( I have no real intention of keeping those 4 bargain / cheap / temporary phones ).  By the way, just to be clear, I was told i could simply return phones after the port "process" finished or keep them as back ups.  However, I am in my 14 day buyers remorse window which means if I wait after that and call to cancel my tmobile, they are going to try & stick with the full price of those 4 phones ( 2 K20 pluses & 2 REVVLs).  Last sentence... once I got over to customer care, I got Enzo (yes, like Ferrari) and he hung up on my TWICE:  Yes, twice, called back once to claim we were disconnected said he had a colleague listening in, and 30 secs into the call back, hung up again! If the call really did drop, then I dont want this service.  I never had dropped calls with verizon. If my phones were not compatible, they should said so in the beginning. If you are reading this, go into a store and have your current devices checked for compatibility.  Oh by the way, I went to a tmobile store 3 weeks ago with my son, walked around the store 3 times, and no one greeted me.  I should have known then...  I also found out I have 50 days to return to verizon like nothing ever happened.

                    Thank You,

                    Spent Three Hours Trying to get our new T-Mobile Service on Version Phones Working.

                    Was on the Chat Windows with support. 

                    We could Send MMS but not Pictures...  The Settings in BOLD Seem to have made the difference.

                    We have an Android S7 S5 and J3

                    None of them would send pictures over text. Until these settings were changed.
