Why won't my Galaxy S4 won't connect to 4g?

I bought my phone a few month ago, it was working flawlessly on 4g LTE. two days ago, it stopped connecting. I was 1x or 3g. Verizon tech support had me remove the battery, wait 20 seconds and restart, still wouldn't work. (they said no network issues in my area). Then I called samsung and they had me delete the cache using the safe mode menu, that didn't work. Then they told me to do a factory reset, still no luck. Has anyone else had this problem?

Turn off the phone, remove the SIM card, wait a few minutes, then re-insert the SIM card, power the phone back on, and give it a few minutes to establish a fresh connection with the network. If that doesn't help, try a new SIM card (they're free at your local Corporate Verizon store).

the_bruce, thanks for trying all the basic troubleshooting steps. We appreciate your patience while resolving this issue for you. After you factory reset your phone, did you redownload the same 3rd party applications that you had before? Some application software can affect the performance of your device. I recommend that you uninstall a few applications and briefly remove the sim card to soft reset your device on our network. Keep us posted.

Yes. My problem started yesterday, Dec. 19th. I bought the phone Nov. 29th.

I've tried removing the SIM card. I also uninstalled some apps that I installed in the last day or two. No luck.

What worked for you?

Hello Sinophile. Since you have already gone through a few of the steps mentioned above, we would want to make sure your software is current. To do this, please go to Settings, More, About Phone and select Software Update. If there is an update available, please download the update via WiFi and once complete test to see if your 4G connection is working. If you are still experiencing problems, I would recommend replacing the 4G SIM card. You can visit your local corporate store for a free 4G SIM. http://bit.ly/3SdsA

Thank for this post I guess I may need a new sim card. Since the last software update to the phone I lose 4G all the time. I drive the same route to work every day and always had a steady signal now I go to 3G or searching for service all the time here in central Virginia. I have rebooted, removed the batter, factory default none of it made a difference.

What I also noticed after the update when my phone would loose its signal in an area where I have had a signal in the past it would as if I want to go to global mode and use GSM. I forget the exact message about global mode becuase I used the check box to stop asking me.

Have you ever seen the question if to go to global mode after loosing connectivity?

My phone is the S4.

@whydidibuy,

Getting the fastest speeds is definitely a must! I understand your concerns with the change of the service on your phone after the update.

Are you not picking up 4G at all or is it fluctuating to 3G? Does it only happened while driving to work? What's the zip code where you're experiencing this issue? I see you mentioned you were going to try a new SIM card. Did you already get the new SIM card? If not you can get one for free at any VZW store http://bit.ly/3SdsA.

I also have the same problem, it only shows up as 3g even when outside my house, where i was able to get 4g before.

This has lasted about 3 months now.

I chatted with someone online and they sent me a new sim card, same thing, still 3g, is there something that you can do to make my account 4g again? This is really irritating.
