Elliot B. Posted March 28, 2014 Share Posted March 28, 2014 I've heard the H+ symbol should turn to 4G symbol when in a 4G area. I've never seen the 4G symbol appear when I'm definitely in 4G areas (including Birmingham and central London). Is the information I've received wrong, or is there a setting wrong on my phone? The phone is set to "WCDMA/GSM (auto connect) and is running the latest Samsung ROM (Android 4.4). My service provider is Three. Link to comment Share on other sites More sharing options...
Chris123NT Posted March 28, 2014 Share Posted March 28, 2014 Set your nework mode to one that includes LTE as well and you will get 4G in 4G/LTE areas. Link to comment Share on other sites More sharing options...

Chris123NT Posted March 28, 2014 Share Posted March 28, 2014 Oh wow there should be one that has LTE in it. Is your SIM card old perhaps? Maybe it's not LTE capable, or something is botched with your S4. Link to comment Share on other sites More sharing options...

Maybe it's not LTE capable, or something is botched with your S4. The SIM card is only a few months old. I'll give my service provider a call.

riahc3 Posted March 28, 2014 Share Posted March 28, 2014 Do a speedtest; Doesn't matter what icon appears, doesn't appear. Link to comment Share on other sites More sharing options...
Elliot B. Posted March 28, 2014 Author Share Posted March 28, 2014 Do a speedtest; Doesn't matter what icon appears, doesn't appear. True but I'm also missing the LTE option in the screenshot above :( I'll do a speed test soon - I'll be in town. Link to comment Share on other sites More sharing options...
TAZMINATOR Posted March 28, 2014 Share Posted March 28, 2014 My S4 does the same thing.. I have LTE in the network settings. my icon won't show... my Note 2 can show 4G, no matter where I am at. Link to comment Share on other sites More sharing options...
theyarecomingforyou Posted March 28, 2014 Share Posted March 28, 2014 Oh wow there should be one that has LTE in it. Is your SIM card old perhaps? Maybe it's not LTE capable, or something is botched with your S4. I have a 4G compatible phone on a 3G network and it still shows the LTE option. Perhaps the phone doesn't support it, as I know with the Galaxy Note 3 that not all models support 4G. I know somebody with the same phone on EE so I'll check with them.

theyarecomingforyou Posted March 29, 2014 Share Posted March 29, 2014 Have just checked and the Galaxy S4 shows LTE in the network mode for 4G, meaning it looks like your phone doesn't support it for whatever reason. Link to comment Share on other sites More sharing options...
Ryanjmchale Posted July 27, 2014 Share Posted July 27, 2014 Root you phone, use a root explorer, navigare into Root/Data/Permissions folder and change the ?false? in file persist.radio.lteon into ?true?. Be sure permissions of persist.radio.lteon are set back to rw, after altering the file save the file and make it read-only. Reboot and you will have the option. Alternatively update the CSC although you will generally lose your data. I had to do the first method on my Note 3 for threeuk as my CSC is PHE (Spain), it works perfect now.

Bigkaye Posted July 27, 2014 Share Posted July 27, 2014 If it was rogue unlocked it will do this (basically unlocked without unlock key). Known problem with S3/S4. Unfortunately no simple fix. Link to comment Share on other sites More sharing options...
dancedar Posted July 27, 2014 Share Posted July 27, 2014 Have you the i9500/octa core version of the S4, as it doesn't support lte/4g? Link to comment Share on other sites More sharing options...
Ambroos Posted July 27, 2014 Share Posted July 27, 2014 Go to the dialer and try to enter *#*#INFO#*#* (INFO = 4636). Select Phone information and scroll down to "Set preferred network type:". See if you have LTE only available there, or use LTE/GSM/CDMA auto (= 2G+3G+4G). If you get LTE with LTE only enabled, your phone supports 4G and you just need an update to enable it in the regular menu. Don't touch anything else in those menus, and set a regular network mode with the regular settings menu after testing. I use this method often to force LTE for speedtests. Remember that you cannot make or receive calls on LTE only. Edit: I only just now noticed this is an old post. :pinch: Piggy 1 Share Link to comment Share on other sites More sharing options...

Open Minded Posted July 29, 2014 Share Posted July 29, 2014 It sounds like you need to check your APN settings.
