Cant view home cameras with T-Mobile iPhone but can with AT&T service.

I no longer can view my home cameras from my iphone when on cellular. It works fine on wifi but will not work on T-Mobile cellular service.  To make this worse is I have a iPad with AT&T and that works fine with both wifi and on their cellular service. Cameras worked fine on iPhone until about 2 weeks ago. I also have two different apps with two different cameras and the same result on both. Works fine with AT&T cellular but won't work with T-Mobile cellular service. I spent about 2 hours with T-Mobile support chat and on the phone yesterday and at the end was told by the person that "oh yes its normal for people to be able to view on iPad but not phone and it only works on iPad because it's a iPad and not because it's AT&T". Clearly that is wrong. This USED TO WORK ON MY IPHONE with T-Mobile until weeks ago and now doesn't. I have been a T-Mobile customer for lots of years now and spend almost $250 a month on their services and if I can't get this resolved I will be moving to AT&T. What's the point of having home security cameras if you can't view them unless you are on wifi somewhere.  Please somebody help.

One other tidbit: this is only a problem with iOS 11; my iPad with ios10 does not require VPN to work. Me thinks it is IOS related.

cant vie in live view on 4g with att or tmobile..

ipv6 made no difference at all. ven if i forced ipv6.

however this worked for both.

if i turn the phone into a hotspot while they are on 4g, and connect to the other phones hotspot with either a att or tmobile phone, live view works. weird.

so this doesnt mater if its 4g or not.

something with the way the app handles the connection.

i need to port scan everything and see.

I know this could be a few months old But I've been having the same challenge with my ip cameras,this happens  after  my phone  Major update   I call the cameras manufacturer they did everything  to try to  figure out  then I Call T-Mobile they refer me to my mobile device manufactory after searching in reading and talking to friends I went back to T-Mobile Tech Support there were able to reset my phone to ivp4/ivp6  So far my cameras of working beautiful  Thank you I just want to share that with you guys

Did you get a solution to your issue? I ask because I have the same issue and was just on the phone with tech support and they couldn’t give me an answer. I was able to view my cameras on Verizon fine but not with T-mobile. I would really like to know so I can fix it on my end. Thanks

The solution is to use a VPN.

Here is the solution - Note 10 Plus -5G

You need to make your APN default to IPv4 for your cameras to work

Step by step below. (your steps may be different to get to the same menu, but settings will be the same)

APN & data settings

  1. From any Home screen, tap the Menu key.
  2. Tap Settings.
  3. Tap the Connections tab.
  4. Tap More networks.
  5. Tap Mobile networks.
  6. Tap Access Point Names.
  7. If available, tap the T-Mobile US APN (the bullet point fills with green). If not available, tap the Menu key, and then tap New APN.
    Note: To reset your APN settings, tap the Menu key and then tap Reset to default.
  8. Verify and update the following settings for the Data APN:
    • Name: T-Mobile US LTE -IPv4 Only
    • APN:
    • Proxy: <Not set>
    • Port: <Not set>
    • Username: <Not set>
    • Password: <Not set>
    • Server: <Not set>
    • MMSC:
    • MMS proxy: <Not set>
    • MMS port: <Not set>
    • MMS protocol: WAP 2.0
    • MCC: 310
    • MNC: 260
    • Authentication type:<Not set>
    • APN type: <Not set> OR Internet+MMS
    • APN protocol: IPv4
    • APN roaming protocol: IPv4
  9. Tap the Menu key.
  10. Tap Save.
  11. Tap the desired APN profile you want to use then try the internet, then your cameras.

I had the same issue after upgrading from Note 8 to Note10+ 5G.  At first figured it had something to do with the 5G,  so I disabled 5G and still didn't work.  After tons of searching, stumbled on this thread.  Setting APN protocol to IPv4 fixed the issue, or you could even set it to IPv4/IPv6 and it'll work.

Thanks for that.

Unfortunately for iPhone users,  you can't change APN settings afaik.
