Fixed Galaxy S7 APN issue

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!

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.

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 )

T-Mobile S7 Edge - Google Drive

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: 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....

hi, does this confirm volte works on s7 active?

also, will i be able to be on a call and use data at same time? my s6 active always kicks me off data when a call comes through.  network switches to E

Thank you!  This has worked for me perfectly. 

I'm having the same issue. However I have a sprint phone. Not sure if that makes any difference. But I was told that the internet won't work. I'm at a loss with.

That worked perfect!

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.

No I was not able to. When I was making the switch the rep on the phone said I was able to use the phone. I would never had switch if I knew I couldn't use the phone. Waste of money

I tried the fix a few minutes ago and I can say it definitely works! Thanks so much! I wish the T-Mobile reps would read this message board. I spent over an hour talking to him with no fix.

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?
