Data issues

Seems like my phone is fluctuating on edge and 4G signals ways too much as compared to other phone I had on the network.
Is it me or others are having the same issue as well

I do too. Pisses me off. It does it in full 4g areas too. Also, it drops data connection. Was trying to watch the Olympics earlier and it kept kicking off data. :banghead:

If you want to stay just on 4g and eliminate the phone going edge completely, you can dial *#*#4636#*#* or download an app called "phone info", select Device Information", then halfway down there's a dropdown (currently on GSM auto). Select WCDMA only.
There's also a new radio if you don't already have it that is supposed to be better at holding on to 4g longer

i thought i was the only one. talked to tmobile and got a replacement. it still does it on occasion. One thing i did was to change the APN of the phone to a known T-Mobile alternate. it seems to have fixed the issue. if you change your APN to these settings, no more drops, and no more high ping issues.

APN : internet2.voicestream.com

those settings were for my old unlocked iphone. same speeds, lower ping, no more drops.

Just change it back to GSM auto(default) or WCDMA preferred.

No LTE (Ktoonsez AOKP)

Hello,
I'm having an issue with the rom I have (AOKP Ktoonsez) when I turn on data I get H+ at the top. How do I get LTE? I went into that menu by putting in *#*#4636#*#* in the dial pad and putting it into GSM/LTE, but I still get H+. I'm with Virgin Mobile Canada. Here's my APN info:
Name: Bell
APN: pda.bell.ca
Proxy: web.wireless.bell.ca
Port:80
Username: Not set
Password: Not set
Server: Not set
MMSC: http://mms.bell.ca/mms/wapenc
MMS Proxy: web.wireless.bell.ca
MMS Port: 80
MCC:302
MNC: 610
Authentication Type: Not set
APN Type: Not set
Anything missing? This rom does have LTE and I went into the FAQ page, the dial pad method was the only way we could turn LTE on. Thanks.

I'm on att so I'm not entirely useful in the regard to the fact tour on virgin, but are you absolutely sure that apn set up is for lte, that's the first thing I would check.

Yea I know you can get lte working just do a search there is a thread on it and it has everything you need to get it working.

Delete all your apns. Do a new one for bell lte. Then changed preferred network to lte/gsm. Restart phone right after. You should be able to start seeing 4G now. Make sure you remember to restart phone after you change the settings.

Alright, I think I'm going to call them to get the LTE APN in case I am actually missing something. Otherwise I may need a SIM card change.

In the *#*#4636#*#* menu under phone information, try setting it to LTE only and see what happens. I keep getting H+ or less on my CM10 rom unless I do that even when I'm in an LTE area.

Make sure you have LTE/HSPA enabled in Settings>Wireless and Networks (More...)>MobileNetwork>Network Mode. Sometimes when I flash a new rom it changes. I have it HSPA only because saves battery.

When I set it to LTE only, I lose signal to my carrier does that mean anything at all? And for the options under settings I only have a choice between two, GSM/WCDMA/LTE and GSM/WCDMA preffered.

Pick the lte mode and click the lte apn and restart your phone right away. It should work right after. Btw if it says 4g,it means lte is working

Also a Virgin Mobile Canada customer and my S3 has NEVER said 4G or LTE in the signal bar.... H+ is what it displays on stock touchwiz, AOKP CM10...

I'm a Virgin Mobile Canada customer as well. I've set my preferred network type to LTE/GSM auto (PRL) by accessing the "Testing" menu (dial *#*#4636#*#*) and have selected LTE/GSM/WCDMA by going into my mobile network settings. The only two modes I can select from are LTE/GSM/WCDMA and GSM/WCDMA preferred
I've noticed the following:
-most of the time I'm on either the HSPA or HSPA+ network
-there are times at which my notification bar shows 4G (which I assume is LTE) but it definitely isn't as frequent as when my phone was unrooted and on stock
-this one is weird: occasionally I lose total mobile and data connection for about a few seconds and a "warning" icon shows up in the top left corner of the notification bar. When I expand notifications it says that the connection to the VIRGIN mobile network has been lost..or something along those lines. I'm usually able to reconnect automatically within a few seconds but this is definitely a weird one since I've noticed it only after flashing Task&Ktoonsez AOKP. Anyone encounter anything similar to this?

Hmm maybe this is just Virgin Mobile problem? Thing is the ROM I was on before, (Team Insomnia JB Touchwiz) it showed 4g when I turned on the mobile data but I was getting no where near LTE speeds. I also tried switching to LTE mode and clicking the LTE APN and reboot, but all it does is go back to WCDMA Preferred mode. I got a SIM replacement from Virgin Mobile but still no luck after this.
EDIT: I think I got it, if you recently were on a Virgin Mobile Supertab or changed from an older phone that didn't have LTE, make sure that Virgin Mobile systems know that you own a Galaxy S3. I went into my Virgin Mobile "My Account' and it showed my phones it only listed the HTC Legend I had few months ago, but not the S3 itself, and beside it saying this device runs on a HSPA+ network. I'm getting this fixed on Monday so I'll see what happens then. If somebody can do it sooner though if they have the same issue, that would be great too.

LTE/CDMA in ro.radio.networkmode screws up phone.

Hi, guys I recently ran into an issue with the build prop modification in regards to network selection. If I enable the network selection as pointed out in one of the other threads and select LTE /CDMA my phone will lock on LTE however no phone calls can be made out or recieved. I had to reflash to 10k then reroot and then change the build prop to CA/TLS and finally hardreset via stock recovery. Anybody else have this issue?
UPDATE... looks like as long as i dont try to make a call the option to switch it back to auto is still there. One a call is attempted and fails the option to set to auto disappears.

Most carriers Phone calls and Texts dont go through LTE...... If your setting it to LTE only thats why.

I understand but after it's been on LTE for a while it doesn't give you the option to switch back.

Depending on what rom your using under mobile networks there is network selections with
LTE/WCDMA/GSM
GSM Only
WCDMA Only
and LTE only

How are you changing it? Changing it via Build.Prop? Then there is your problem, JUST change it using the setting under mobile networks..

Stop changing it to lte/cdma and you're phone will no longer mess up. Leave it on gsm/wcdma/lte auto. You're phone will switch when the appropriate network is available!!!

Simple fix. Just select airplane mode for a few and then toggle it off and you'll see your network options come back once data roaming turns off and your carrier logo appears. I typically run lte/CDMA to get consistent lte speed bit when a callsade I have the same issue as you. But I just gave your the fix so your good

Thanks a lot captain obvious, the point of the thread wasn't to "not switch it" dude, it's finding a work around and make everybody aware of what happens.

Flashed darthstalker and now I can't get LTE signal.

This seems to be the only issue. Do I need to change some settings somewhere after flashing or should I just try to reflash the whole thing.

T-mobile lte is selected and the settings are filled out. What could have caused the lte to stop working? It doesn't seem to matter what I do.

When I flashed it, network mode was set to 4G. Changed it back to LTE and got back my LTE.

Ok I am back on the stock rom and I am still stuck on the edge network and my apn settings are greyed out but look ok. The network mode is on lte/wcdma/gsm and the status bar says 4g but I have no signal bars and extremely slow spped unless I am on wifi. I can get calls and texts though. Anything else important to solve this?

Sorry for double post but my imei number is 15 digits long if that matters.

LTE GONE
Bump... Having the same problem! Tried everything with respect to network mode, APNs, *#2263# and flashing different roms.
Although it worked at first, LTE disappeared on me out of the blue. Any ideas?

[Q] ATT signal troubles on H815 US

I purchased my phone (h815 US model) online from swappa and I love the feel and look of the phone, Love the camera, BUT my phone wants to stay on hspa all the time. Where i had 3 or 4 bars on my s5 active I get HSPA unless I go in to settings and sellect ATT:LTE from network operators which only last until my phone goes to sleep then im back on hspa. Anyone else experiencing this? Or anything i should try? Thanks in advance for any help!

Bumpers just in case someone who knows didn't see it. Sorry won't bump it again!

Maybe with hidden menu access via dialer,you can permanently enabled it...I don't know the actual code that might work for your device..but you can find it through here..In general threads maybe

I had to set the proper APNs on my H815, additionally I had to tell it to use GSM/WCDMA/LTE Auto under Network Mode in the Mobile Networks settings.

After that, it's been using LTE where available.

Thank you @Daptonic . I was attempting to use the "ATT nxtgenphone" APN because it works better on ATT devices but I guess the ATT Phone APN is needed for non ATT devices. Rebooted phone and it went straight to 4g. Thanks for responding.
Edit: dammit, it went back to hspa again......
