4G LTE not active - Galaxy S 4 Active Q&A, Help & Troubleshooting

I have an unlocked Galaxy S4 active i9295 and I cannot get the 4G or the LTE working since I do not have even the option I only have WCDMA/GSM I travel around the world with this phone and now I am in Ireland on 3 and still I am getting H+ showing and not LTE or 4G. Is there a way to activate 4G or is there any special 4G sims ?

I would check your APN settings, seeing how you are unlocked, the proper APN may not be installed to match your Sim, check with your carrier, to make sure they are 4G and LTE capable and get their settings.

Try ShowServiceMode. It should help to unlock LTE band. It worked for me here in Poland, because local career's LTE was locked by my Russian firmware. But using this program I can only switch between phone calls (GSM/3G) and LTE, they cannot work simultaneously.

Thank you guys. One major thing is that why I can even see the option in the settings? If anyone else has some information please help out.
Thanks

I can't really help you but as far as I know LTE is already unlocked and working on all international S4 Actives. Mine certainly worked perfectly out of the box - although I turned it off promptly because I have ****ty 4G coverage where I live so it was nothing but a battery drain for me.
Are you sure you have a 4G sim card, and that you are in an area where 4G has coverage?
If you go in under settings > connections > more networks > mobile networks > network mode don't you have the LTE option at the top?

Im not 100% but i got the textmessage from my provider, so i recon they only send it to people who are able to use the 4G.
Yes, i am in a 4g coverage area
i dont have the LTE option at the top no. i have:
- wcdma/gsm
- only wcdma
- only gsm

Well then I really have no idea - the only thing I can think of is that you might need to replace your sim card if your provider didn't already do so in advance of the 4G rollout. Hopefully someone with more information might step in here, but the international version is LTE capable out of the box. If you don't hear anything else I'd suggest to try and contact vodafone and get a clear answer from them first.
If you check the mobile networks in your area and don't see anything that supports LTE, you may just live in an area that doesn't have it yet (people get 4G and LTE somewhat mixed up - 4G is the overall identifier for a whole class of technologies with "4th generation cellular networks" basically while LTE is technically one of those technologies so, it should rightfully be classified as 4G in most respects.
Having said that, the only way I got my GS4A to function in LTE mode - meaning it actually shows LTE in the notification bar under the 4 with a small G and LTE underneath it - was to go into the service menu (*#*#4636#*#*) and change the preferred network type to either LTE only or LTE/GSM auto (PRL). Once I did that the radio would reset and connect and then it would be in proper LTE mode. Doing a speedtest with the Speedtest.net app shows LTE as the connection whereas with my standard setting which is WCDMA Preferred (T-Mobile AWS) it'll just show as "4G."
I've had no luck making alterations in the Settings/Mobile Networks section, I have to change it in the service menu to get LTE functional. I don't use it because here in Vegas where I live (specifically my home location) the LTE mode gets me about 1-2 bars of signal (about 8-12Mbps) whereas the WCDMA Preferred setting pulls in 5 bars rock solid and 25-35Mbps.
Can't do screenshots or I'd add them, I'm running the pre-release MI2 ROM presently and that aspect is borked.

I can check my area on the vodafone site. I live in a 4G network area 100%!
i guess my wcdma is sufficient then.. didnt experience speedboost tho..

That would be because you're on the i537 from ATT, rather than the i9295 that this discussion is about. I checked google and vodafone holland does indeed use LTE on the right bands in its brand new rollout, so it isn't that - most likely it's his sim that needs replacing or it's just not activated on his account yet.

[Q] Can't get LTE connection on Fido

Hi All,
Got a new xperia Z1 c6906, setup all things, did input correct APN, chose LTE in the mobile setting. But it couldn't get LTE connection, it always go back down to H+ / 3G, always switch between H+ and 3G. just wondering if the baseband problem? or I have to call Fido and ask them to register my IMEI to their LTE network if the phone couldn't do it itself? thx so much anybody can help.
p.s. previously using Samsung SIII, using LTE sim card and sure in LTE area since I didn't move.

BTW, you should post this on Z1 forum.

[Help] At&t moto x LTE issue

I seem to cant get any LTE connection on my at&t moto x.ive downloaded the phone testing app and i cant change it to LTE/GSM or any LTE connection for that matter it stays on GSM auto. Any help or ideas please? As of right now im only getting hspa/hspa+ connection
Google your carriers APN settings and see if yours match.
Other than that, it can only be a Sim card issue or carrier issue. Assuming you mean an AT&T model phone on at&t's network.
Or is it on another network? If so.... You may not have the bands supported on the phone that your carrier uses. Nothing you can do about that if so.

Using S6 edge outside of USA

Hello,
Can I use verison version of this phone in Europe (serbia, slovenia...) normally? Can I turn off 4g/LTE if I need and use only 3g/hspa connections? In my region 4g signal is pure and I have a problem with battery and signal. Does secret menu *#*#4636#*#* works of this version of phone? Thank you.
U can use this phone. Just replace with a local sim card. There is an "unrecognized sim" icon constantly in the notification bar, but other than that everything works the same.

I lived in Spain with the g925v and it does work, but only on 2g/3g, no 4g LTE signal. By that time I was running Android 5.0.2, I believe that with the updates the European LTE band is usable now but I can't assure that.
You can turn off the LTE antenna accessing the menu with this code *#27663368378#

Unlocked G928A on Tmobile, 4G LTE Unstable going in and out

I got a unlocked AT&T G928A, its currently on Tmobile but the 4G LTE keeps going in and out on it, it skips to Edge and then back to 4G LTE. I checked the phone does have LTE B12 and B4 which is what Denver uses for LTE band. Anyone know how to troubleshoot this? I have tried to do a master reset and verified the APN settings to be correct.
