Hello everybody. I'm hoping some light may be shined as to why I'm only getting 3G on my L710/Virgin Mobile w/o Spark.
Any ROM that I have flashed that is LP yields 3G, this is even after flashing the R2 APN fix. I've set APN under Network, but to get any data, I have to choose 3G as my preferred mode. It works alright but I'd rather have LTE.

Hello all, I'm hoping somebody will be able to help. I've got a desire HD on 3 UK (I haven't contacted them coz tech support is useless and I don't want them to know I'm on a custom rom), running LordClock's ICS 8.6.1, My data works fine on 3.5g but as soon as phone switches to 3g I get no data at all. I've tried various roms I've Googled for hours and found no solution. I've checked APNs and tried various versions found on web, I've tried changing the WCDMA preferred option in hidden menu, I've cleaned and reseated the sim, and tried turning airplane mode off and on The annoying thing is data has worked on 3g on Ice cold sandwich in the past, I think v7.3. I was wondering if it had anything to do with build prop and have changed and added various lines but with no success. Any advice or suggestions would be greatly appreciated and thanks will be given to anyone who contributes. Thanks.
What do you mean by switching from 3G to 3.5G? There's only a toggle to switch between 2G and Automatic mode (2G/3G) in ICS right? How are you switching between the 2? Also what is this hidden menu where you switch to WCDMA preferred? (Just for my knowledge. I don't know about it). Does it work for you with different ROMs?

Hi sashank, I meant just that when I lose a 3.5g signal and it automatically drops down to a 3g signal I'm not switching it myself, and if u go into the dialer and type *#*#4636#*#* u get a hidden menu called Testing with gives u info bout network or battery, check it out, the WCDMA option is in Phone info.
Hi, I have exactly the same problem. just to clarify, I am on the 3 network too, and when I have H (HSDPA) signal, the internet works..and works well. however as soon as it changes to 3G..the internet doesn't work at all
you should consider flashing other radios
Hi,
i have network/call quality problem when i flash cm10 on my i747m.
When i'm with the stock rom, i disable LTE and my phone display 4g connectivity.
When i use CM10, i can't get the same connectivity (3g displayed.... no 4g, no H+) and I'm getting strange sounds in background while i'm calling someone
My APN is telus and my network setting is manualy set to GSM/WCDMA
The default setting was set on GSM/WCDMA.
I have a rogers S3 so I changed the setting to LTE/GSM/WCDMA. It was working for a bit then my mobile data completely crapped out and i was only able to make voice calls. I switched it back to GSM/WCDMA and it works, however, the speeds are much slower compared to LTE.
Im not even sure if I was getting LTE at all at the LTE/GSM/WCDMA setting... since the phone only diplays 3g/H+ on the signal bar, it does not say LTE.
I checked the phones status and it did say LTE:3 when i was set on LTE, however, this is when the data was not working and the phone said not connected to network.
Set it to lte in the apn section and then reset your phone.
4g symbol is Lte speed

I was having the same confusion the past couple days, I've flashed the PARANOID ROM (amazing ROM btw!!)
I found all the answers I needed for this right here:

Hello, I'm pretty new to the custom rom world.
I am currently using latest Spirit AOSP cm11/kitkat based rom with the stock kernel that comes with this.
Now If i use the ND8 stock rom, there is no problem whatsoever with the ability to connect to 4g LTE.
But for some reason, when I'm on custom ROM and my device turns off for a long time / I disable my radio (when connected to wifi)--I'm not sure which one causes the problem--the phone just loses ability to connect to LTE.
I use two apps:
LTE Discovery
advanced signal status
advanced signal status lets me see if my phone can find 4g lte signal/how strong it is. When the 4g LTE is working, i get signals in -(number)db, but when it doesn't it just says n/a for all the sections.
with LTE discovery I use it to see what type of connection i get-- LTE when 4glte is working, and eHRDP? or evdo rev. A for when I can't connect to lte.
my APN settings are correctly set-- my phone has data, voice, and text-- it's just the LTE connection that gets dropped for seemingly no reason.
My method of fixing this is wiping data/cache/delvik/system, install stock kk nd8, perform SCRTN, make sure data/phone/text is working
then I wipe data and cache, then restore my rom... that is working..
If I restore to a point when lte was not working, lte will not work..
but doing this everytime my phone can't lte is very tiring..
I don't even know where to start troubleshooting this issue i have..
I don't even know if anybody has the same issue.. or even heard of anything even close to this.. please help
I have been running CM13 ever since I got my OP3 this summer, but today i decided to go back to oxygenos for a bit. Following a clean flash, I could text and use wifi but had no data capabilities. So I went and copied APN info from brothers phone, and I can get lte but after a few hrs and going back and forth from wifi and data, it starts to connect to H+. I have checked mobile data settings and confirmed lte preference.
Any ideas?
EDIT: I downloaded a lte network app that corrected the connection, switching from H+ to lte, but after going on wifi then back off I was back to H+...
