If your model number is not C6603, you can't get LTE Service

Since you flashed an LTE rom, the build prop of that rom is most likely to say C6603.
Look at the printed letters at the botton of your device, above the barcode, there should say the actual model number of your device.

There are no work arounds for c6602, even if you flash a c6603 ftf file, it wouldn't give you LTE capabilities.
If you really want LTE you need to purchase the c6603. Make sure it supports your carrier's LTE network frequencies.

Also even if it was possible, you need that your provider give you a 4G access and a 4G package, you're ****ed anyway, your phone doesn't handle the 4G, i'm sorry for you.
Keep in mind that only few people have actually the 4G access, the deployment is in progress in many countries and many towns and for many providers.

I am living In uae Also and I bought the c6602 Also and I flashed a rom and its written there now c6603. LTE is not only software optmiziation but hardware too. But even if you have 4G its speed is barely over 3G in most of the places. it works fine only in few places
I got 134 mbits and 32 Mbits maximum on iphone 5 (my speed tests)

the hardware is different for both the versions so it wont work

Calls work on 3g, 4g is only for data. Well at least that's how it goes here in Australia

Yes that's true for the rest of the world. Phones should kill the lte connection for calls though. Most probably rom problem. Why don't you check out the thread? Maybe there is a solution already

Thank you all. I did do some snooping around and think I found the problem. Even think I got it solved.

@buckfyter
So what was your problem? It was a ROM problem?
How did you solve it?
Thanks

How good is the hotspot function?

I would like to use my phones internet connection to play battlefield 4 online tru WiFi hotspot function on ps4. Is the phones WiFi fast enough to do this without lag?
My country does not have local console servers.

Wrong forum, this should be in the Q&A section, And to answer your question, depends on your Network provider. If it's LTE and stable then yeah it should work fine.

It depends on your mobile network speed. If you have hsdpa with 7,2 mbps it should be fast enough.

LTE in Poland, World of Tanks, Xperia Z- ping 100. Same sim card and place with Samsung LTE router - ping 50. And check NAT on Vita some games (CoD) doesn't work.

check which server you connect
and servers dont behave same all the time
depends on your hardware as well

This difference is always even at the same time. I've checked it for over one year. And it occurs in other games two.

It's stable and average speed. Pinging 40 on national servers playing counterstrike on my laptop, would be 5 on fiber. Lagfree, nothing spectacular.

Network lag will make the game unplayable - as well as BF4's own awfully bad hit detection and netcode you'll want to kill yourself. Playing multiplayer games using LTE like that will only be viable really for turn based games - maybe like Pokemon, rather then a twitch shooter like BF4.
