I would try different modems until you find the right one for you. There is an app that makes it easy to switch.

Best modem for Europe @CM7 ?

I have CM7 Nightly #42 and I'm looking for the best modem for Europe, Germany mainly. I can't get 3G to work with JVP/JVQ. Would be nice if it's easy on battery, too.
Any suggestions?

I am using JVO. For the 2g/3g toggle to work wait for the next nightlie. This issue has been resolved

Great news that it finally has been resolved! I miss Cyanogen (used it on my G1 sold 10 months ago, but now I'm on stock Samsung ROM), maybe it's time to do the switch.
Italy For what is the best modem? I thank you in advance CM7 "Italy 3"
I'm on #61 and still no 3G... Nothing in release notes of #62 indicating any improvement. Perhaps I should flash JVK modem back?

You can have 3G only by using the settings menu and not the widget
I don't use the widget. I keep 3G on in the settings, but all I get is H/3G flashing on status bar from time to time with H staying there for good.
Since "H" is better form of "3G", it looks ok.
ugh... I'm turning red now, good you can't see it... THANKS!

H stands for: HSDPA, 7.2 Mbps
Basically means that you have access to high speed internet on your phone.
ok, ok, I got it the first time... please do not kick me anymore, I'm laying on the floor already...

Cm10.1 ROM with USA radio band fix. Can now pick 1900mhz for T-Mobile

I've tried accessing the hidden menu via *#*#4636#*#* but when I go to the setting to change radio band it force closes, is there any other way to change it via cmd adb or something? Would like to test the new 1900mhz band ;D

Been trying myself! Don't know where to fix that issue. The Gnex had no problem with that. This one does tho... I live 5 miles from the 1900 tower.

Are you on the stock ROM? If not, that might be the issue (because of the modifications made to it something could've gone wrong in that specific ROM.) You could also attempt to use Phone Info from the play store if it simply just doesn't work in the dialer. There's not many people that have issues doing this, so it could be that you might just have to reset your phone if all else fails.
doesnt force close on me.

This was happening to me on stock ROM/kernel and on two different phones
Basically I just want to know if there is any other method to change it. If not then I'll just wait a random amount of time and try again after a new update comes out

I think it crashes on all phone. It is software problem.
I called tech support and had him tried it on his phone and it crashed too.
which band do you switch it to?

Just Tried it again on CFX SR1 W/ brixked 0.6 and got an FC. I got it stock as well.
But from what ive heard you will not kick into HSPA+ mode until you put a strain on your conection. IE: Idling/web browsing/facebook will not bring you up to HSPA:15 (you can check you HSPA Channel in the settings--->about phone--->Status and then look at mobile Network Type). Knowing that i live in a well covered area i was upset that i couldnt get full 42mbps. But as my research and expereince has shown i can get it, just only when its necessary.
NOW, im not a wireless tech, im not even a rocket scientist, but i have done alot of reasearch and the data matches my hypothesis so ill lay it out for everyone to tear apart.
HSPA+ 42M works by using a Dual Carrier signal, which of course uses a bit more power than a single carrier. So even if you have a perfect -0dbm signal strength, you will only see HSPA:10 [ aka 21mbps ] in your network type. BUT, if you put a load on your connection ( in my case i took a multi hundred meg file into dropbox and then downloaded it) you will see the speeds increase signifigantly past the first little bit of data transfer, and if your are quick about it or cook up some sort of widget or overlay you can see the phone kick up to "high gear" and use the HSPA:15 channel.
i have also seen this in effect with larger apps. For instance the Ingress update that i got earlier today downloaded in these steps: 756k - 1.3Mb - 3.5mb installing. in ~ 10 seconds.
tl;dr Phone idles in low speed mode, goes to high speed when needed.
So if you want to test for yourself and have a bit of data left on your account (in 3 test i burned ~ 250MB) start a big download and then quickly switch to a view of the network type.

In this thread, we are talking about changing TMobile 3G bands: 1700 (current) and 1900(new, refarmed). We are not talking about HSPA, HSPA+, etc.
Mine FC's as well. I'm unlocked and rooted only

Well no one has a solution or an actual idea about what the problem is so I guess we will just be waiting x amount of time for a fix. Maybe a ROM dev can look into this and fix the issue because it'd be really nice to use the new 1900mhz bands. Can someone do a log cat and see what the issue is? No laptop ATM.

4g is lte on liquid, but it shouldn't be slow. Have you checked your apn?

yes i have checked the settings there they seem correct..
when i run a speed test like ookla my DL is .70 Mbps and UP is 3.66 Mbps
Maybe the place where you made your speed test isn't so good. I had the same problem. I had slow lte speed and then I realize it wasn't because of the rom but because of the reception so I go somewhere where I have a better reception and I get LTE speed. By the way, lte is not always covered everywhere in your state.

Can't get LTE working on CM12.1

Hi, so today I have installed CM12.1 unofficial on my S5. I loved the rom, everything was perfect but I couldn't get LTE working. My Note 4 (N910c) gets 2 bars of indication in the same room, speed is 20mbs+. When I launch mobile data on S5, it takes long to estabilish connection, then only gets H+, and after several seconds it drops to 3G What can I do? CM is blazing fast compared to stock ROMs, but I can't imagine myself using 3G to YT/web etc... Help please! I have the newest modem/bl (BOC7).
I'm sure you've already checked your APN settings to be what your carrier advises. If not that is something to start with.
If you're on att,
Also look into your build.prop to add in/modify the following accordingly:
ro.product.model=SAMSUNG-SM-G900A
ro.product.name=klteuc
ro.product.device=klteatt

I am not ATT, i'm from Poland so Soo.. weird situation today. I've been in city centre where LTE signal is pretty good. For like 3-4h it was constantly switching between 3G/H/H+, and suddenly it caught LTE. Now I am at home and it still connects to LTE, 2 bars just like in Note 4. I am pretty confused now. It seems that modem/kernel/APN are all right, maybe a kind of system trigger that "stabilizes" the signal? 3G/H+ has 5 bars here, LTE only 2. I have already put a tick to "LTE (preffered) in network options. How about this?
EDIT
Rebooted the phone, again, no LTE
Wow that is cool! I remember my CM12 used to constantly wobble between H/H+ and once I finally gave up messing with it and screen turned off for 15-20 minutes, I'd turn the screen back on and find myself on a 4G LTE signal (feeling great). Once I made a call it drops to 3G, which is normal, but after I'd hang up it wouldn't necessarily switch back to 4G any time soon.
So I gave edgarf28's XtreStoLite a shot and haven't looked back since! It is touchwiz based, but it is light, debloated, lighting fast, and it just works. I'm on XtreStoLite 2.1, and I have no complains at all.
I have the same problem on a SM-G900T running on AT&T. After every reboot can only get H/H+ leave it alone and will grab LTE 10 to 40 mins after the screen is off. Leave the screen on and won't grab LTE. And of course make a phone call you lose LTE connection. And how long it takes to get back is very random. I can't find a solution to this and got a G900T so I can run AOSP. I was tired of touchwiz and trying to get themed apps and dialers. now I am screwed I wish I could find a solution to this.
No 3g but have lte
I know this is probably in the wrong spot so I'm sorry.
I just clean flashed my sm-g900r4 to cm12.1 cyan ROM 20150428
I have working lte data but no 3g, so when I move out of lte area the signal icon just shows an exclamation point, any help would be greatly appreciated.
The way I fixed mine was by removing all apn entries I didn't need. This caused the search for LTE to speed up no issues since

I really don't know why the development stopped for klteusc, but if I were to guess, I'd guess it is probably covered under another variant.
For example, since klteusc is a cdma phone I won't be surprised to see US cellular CM getting absorbed into kltespr development. But this is just a hypothetical scenario because I couldn't find any proof. But it is worth looking into if anyone is talking about it online.

Nexus 6 on Ting...

Been on Sprint for years an decided to try out Ting to see if I can save a little money.Yes I'm Rooted an been using all kinds of Roms.I was just wondering if anybody else out there is using a Nexus 6 on Ting an if they have any info that I would need to know. I did notice I only seem to get LTE if I'm on a Stock ROM other wise it says 3G..Just want to hear about other people's results etc...Thanks
