Galaxy S5 won't connect to AT&T data network

I updated my Galaxy S5 last night and ever since I can not connect to the AT&T data network. I can only access the internet over wifi. Is anyone else having this issue? Any suggestions on how to fix this?

Re: Galaxy S5 won't connect to AT&T data network

I am experiencing the same problem. I have gone through the trouble shooting but it still will not connect even though it is set to enable. Is there a fix for this problem?

Re: Galaxy S5 won't connect to AT&T data network

Hey @edpotts42

 

We have been receiving reports of connectivity issues with the Samsung Galaxy S5 after updating to 4.4.4. We are currently working with Samsung in order to identify a root cause and fix for this issue. As appears to have helped for some of the customers who have posted in this topic, the issue appears to be related to Smart Switch which can be addressed by disabling this feature. To do so:

 

  1. Go to Settings>Wi-Fi>Smart network switch

 

  1. Remove the mark in the checkbox.

 

We appreciate your patience as we work with Samsung to find a permanent solution to this issue.

 

Thanks,

Charise

Re: Galaxy S5 won't connect to AT&T data network

I just worked with AT&T service support and the young ladythat helped me had to reassign my IMEI number. The phone is now getting mobile data. I tried everything else as shown in the trouble-shooting section of ATT. If anyone is experiencing the problem of no mobile data, i would contact AT&T.

Try checking the access point name settings in your device . Sometimes when an update happens these settings are erased and you will have issues connecting to the mobile data network. If you can go into you settings of your device ,and under the tab for connections tab you should see more networks select this option , then select mobile data and within that selection you should see the option for access point name.  the settings should be

  1. Access the Settings menu.
  2. Locate and select Wireless & Networks or More Networks.
  3. Select Mobile Networks.
  4. Select Access Point Names.
  5. Locate and select the option to add a new APN. This is usually accessed by a + symbol on the screen or by tapping the menu button.
  6. Program each field using the settings below.
  7. Save the changes to return to the APNs menu and select the new APN.

Re: Galaxy S5 won't connect to AT&T data network

I acually have my AT&T Samsung Galaxy S5 on Metro PCS but having the same trouble.

so I looked up MetroPCS APN settings and followed the settings I found online.

They were different from the setting that was on my Galaxy S5.

After I changed the APN settings my 4GLTE mobile data was working fine! (:

I was having the same problem with my Samsung Galaxy 4.

Which, now a days, who wants a phone without data! YOU SAVED ME!!!! THIS WORKED LIKE A CHARM!!! THANK YOU SOOOOO MUCH! I was at AT&T for an hour today and they could not figure it out. Told me I needed to get a new phone. THANK YOU!!!

Re: Galaxy S5 won't connect to AT&T data network

None if this helped. I have been having this problem for a month or so. It just happened randomly. I have tried several apns. I have called At&t 3 times. It will not connect to the At&t network. But sometimes it will. It will only connect for a minute or two and will only connect using 2g. I have sick and tired of it not working. Any advice/help will work. (Phone: Galaxy s5 Version: 6.0.1)
