One X on AT&T H to 3G to H... rinse and repeat!

Guys,
Unlocked and rooted One X on AT&T and my pegged out signal keeps changing from H to 3G over and over and over.... you get the picture. Never stays on one very long before changing and will disrupt data services for a brief moment while it does.
Is anyone else seeing this behavior and if so, any fix to resolve?

Yea I notice it. I believe it's part of the way it saves power but idk if thats true because on my Galaxy Nexus, it would almost always stay on "H".
Mine doesn't really switch out of "H" though when actually loading something, just takes a bit to go from "3G" to "H". I've maybe experienced it once or twice when actually loading something where it would switch out of "H" to "3G" while loading something on XDA or a website. But it's usually when connection is weak.

I'm having the same issue.

if it keeps happening, then complain to ATT and ask for credit on your data plan because it doesn't work the way it should.

From what I read, AT&T phones show only h, even though in the background they switch back and forth.
But when you use international phones on the network, it will show the switching around. I'm not sure if that's related to your issue, but over here on rogers, my phone switches between 3g and h constantly, even when I'm at one location.. The thing is that I don't get long disruptions though, if any at all.

I'm on att and don't experience this. My icon switches frequently but I don't see any interruption in service.

Thanks all, just wanted to make sure that I was the only one experiencing. I will probably go into the AT&T store and see if their One XL display units is doing the same thing while I have mine with me.
Could be that "international" issue type of thing... who knows.

Yes, mine does this too. Im on straight talk which uses at&t and it frequently keeps switching back and forth.

Mine should be in on Tuesday. Think we might have the wrong APN's??

Have you checked the APN settings?

Moving from 2/3G to HSPA+ is by design and called fast dormancy. Here's more than you could ever possibly want to know about it.
http://www.slideshare.net/zahidtg/gsma-fast-dormancy-best-practices
It saves battery life and when working properly it's undetectable. That is when FD is active on a device and the network it's using supports it. (AT&T does). If OP's dropping signal something's wrong. I'd check...
- The APN's you use on AT&T must match the plan that's provisioned in your account settings. If you're on a 3G plan (grandfathered unlimited, MediaNet, data for non-Smartphones) use the 3G (Cingular) settings. If you're on a 4G (non-LTE) plan use the 4G (HSPA+) APN. Wrong APN means funky data even if it seems fine sometimes.
- Older SIMs or SIMs from iPhone's in non-Apple devices have caused problems. As has bad surgery in the move to micro. Pop in to an AT&T store and get a new micro SIM matched to the provisioning of your account.
- Bad phone h/w. In not the above it could be the device.
I've just been across the country on the AT&T network and my phone has performed better than my i9100 in picking up and maintaining a signal (I'm on a 3G plan). It's been impressive actually especially in moving from HSPA to Wi-Fi and back. So with the right settings the phone itself should be fine.

Just tried that and it's not working for me. Doubled checked, everything is exactly as he said. I just don't have the option to switch from what it currently is (MediaNet). There's no radio button for the other two. Even after deleting the original (only leaving the two I just made) and restarting, I have no connection to the network.

I agree, the settings aren't working for me either in Orange County, CA

After you set up the new APN's try deleting the old one. You can always get it back by selecting "restore to default."

I had an unactivated micro SIM that I had my corporate account rep activate so my situation's different than yours; the SIM is tied exactly to the settings in my account. I popped it in, it picked up the MediaNet settings, and all was good.
My phone has a single APN so I can't see the way the settings look when there are multiples. The last setting in the active APN is "APN enable/disable" which is greyed out on my because there's no other choice. Did you try disabling it after you got the new APN's entered? Maybe if you do it'll allow you to select the new APN's you created.

My "APN enable/disable" is greyed out as well. I tried the new APNs in the other thread and couldn't get a internet connection. The only successful APN with the One X was the medianet. Other than that, I'll settle for the medianet but only wanted to change it to get better speeds in my area since this phone is capable of receiving up to 21mbps.

The highest I've seen on either an international phone or an AT&T 21MB-capable phone is 8MBish down. That's in TX where there's lots of bandwidth shared by not a lot of people. In markets like LAX, NYC, and SFO you're lucky to break 5MB because of the congestion. I've seen 2MB and under in Manhatten. HSPA+ speeds on AT&T are very much YMMV.

I agree but just thought I could push a bit more since I'm only hitting 6mbps. Thanks for the info though!

[Q] Flash Phone No Data!

Hi, last night i flashed my sprint lg g2 stock/rooted phone to cricket using DFS, called up cricket and had them switch to the new flashed phone, and since i have not been able to get data 3g or even 1x on the phone.
I have flashed several phones and never encountered this problem, but this is my first LG phone, Rest were samsung and HTC
Texting and Calls work Great
It constantly lets me know "Mip 67" "Mip 111" and "Unable to Establish a wireless data connection" .
I have searched everywhere and although i can similar people with the problem, all are on sprint.
I have gone through DFS settings many times, reflashing, and nothing is seeming to work or stick
Any help or guidance would be much appreciated, an andorid phone without any internet might as well be a flip phone

Have you tried updating your profile while on WiFi?
A lot of ROMs for the g2 require this

update the data profile? i do click update when the mip error pops up, but it always fails..
ive done *228 multiple times, but doesnt get the 3g going

Are you connected to WiFi. I'm on sprint so I'm guessing. What band does cricket use?

yes, whether im connected to wifi or nothing it gives error.. this is normal with sprint optimized apps when on a flashed cricket phone though.. sprint connection optimizer wont work for all the right reasons... ok i made progress, got 3g, reflashed with simple ip only, no mobile ip. and i get 3g, but not consistant.. but its about progress not perfection! still open to help and advice to solidify this rocky connection
edit: anyone know how to edit the apn settings?? I go to settings and all, i can see yhe apn settings but cannot edit them... first time ever for me on that one

i wish it was that simple. He has a cricket sim card and somehow able to edit his apn settings.
on mine, its a sprint ls980, still has a sprint sim card in it..
update on whats ive notice over the day.. Itll randomly connect to '3g', but when you go to settings and status, its only really 1x.. mobile state is usually saying its 'connecting', once it does connect data drops out..
from what i believe, its still trying to connect to spring network for 3g, but will use cricket for 1x. might have something to do with the sim card, but i have popped it out to see what happens and it still as sketchy as before.

Phone stays on HSPA when LTE is available

So I own a D851, currently on T-Mobile with good LTE speeds in my area but quite often the phone switches to HSPA and doesn't utilize LTE coverage when I need it. I end up having to either switch data off/on or accessing the radio settings menu and setting it to LTE ONLY. I understand the slower network coverage saves battery but to just stay there I don't get when I'm getting download speeds of 9mb on HSPA and 30mb on LTE in the exact same spot. The thing that sucks about setting the radio to LTE ONLY is that I can't browse while on a call. Anyone know a workaround?

I had the same issue with ATT, unlocked phone. Made sure the APN was correct, tried may other APN settings, and finally called Consumer Cellular. They advised I did, indeed, have the correct APN (my first version). They did some type of reset on their end, and viola.
On my OnePlus it was the similar. APN was correct, same APN as the G3, but until I called CC, and their reset, phone would not show LTE at all, only H and H+

What are the apn settings that are working for you? I've tried several times to address this issue with CC but lte STILL isnt working on either of our 2 devices. Had no problems when used with an att account.

I am still having this same problem on my LG G3 (vs985) on Cricket Wireless

Straight Talk data issues with custom roms using 4g LTE Verizon sim

Greetings everyone!
Signed up so that I can hopefully help someone else in need with their LG G3 phone using the Straight Talk 4G LTE Verizon sim card.
After many hours of flashing roms and trying out various things, it turns out for some reason other variants of the stock roms like Bliss Pop, CoudyG3, and Skydragon will not work with the data. I can still use my phone and make calls and i can still get text messages and even pictures sent through text messages, but for the life of me data would NOT work.
The only rom that did work again was the Jasmine rom. To my understanding it works pretty close to the stock verizon rom that comes with the LG G3. After the flash, BOOM! Everything worked and data came back to life.
I noticed the APN settings is very very different but this rom wont let you go in it to see it's settings. Surely there is a way to import/export the APN data to push on over to another custom rom? Just weird that after putting this specific custom rom data happily worked again.
BTW, if anyone tries to activate a verizon lg g3 with straight talk, be careful. Though their stupid website said that the phone was already registered with another tracfone provider/service, I was still able to get the phone to work. If after entering your MEID/EMI or whatever the numbers are and the straight talk website spits it back out at you, CALL straight talk. I got screwed and used up the network access code which somehow got lost into oblivion, but turns out that they themselves can manually add the Verizion 4G LTE sim card with the network access code card. (I bought the 4g LTE sim card package from wal mart). As long as the phone is in good standing, it will work!
Thanks. Hope this helps someone else out trying to get it to work with straight talk. I will try and see if there is a way to export this APN setting. I was told by straight talk that you don't need an APN set, but i think they are lying.
Peace!

solved
Back again,
Happy to report im using skydragon Rom with straight talk. Turns out you do in fact need to set the apn in the settings. Just add this apn
acct.tf.gw6.vzwentp
This is the apn for the Verizon 4g lte sim card when you use it. I didn't have to reset the phone but now data works great.

Hey question. I have a Straight Talk S3 currently running CM 11 kitkat based rom and things work great but I found other roms I want to install one of them being a Pac-Man custom rom but I have no data. I have a Verizon CDMA 4G LTE sim coming in acouple days just need the apn settings. Could anyone help me out with this? Thanx in advance for any help.
Sent from my SCH-S968C using xda premium

Surely it is the same APN setting as above. Try it out once you get your Sim card. Also, that S3 being a different phone may pick up on the access point names when you try another rom and set itself up, but if data is still not working, then try that APN I posted on the first post.
Also, be careful that you are actually connecting at LTE speeds as long as your area has it. Flashing to another rom I was only connecting at 3G. Turns out that once I tried another rom, you have to set the preferred network to LTE, then give the phone a reset. It took it a moment after reboot, but LTE finally showed up.
Depending on your phone, there are other settings to be set in it's hidden menu settings using the phones dialer. Just google around.
Hope this helps!

Korean KT Samsung Note 4 is not getting 4G/LTE. It is only getting 3G on ATT Go Phone SIM Plan. At one time on a Family Talk Plan it was getting 4G/LTE. I tried talking to ATT Tech Support but all they did was try different APN Settings and did not work. I did notice the APN Settings would not stick to the NXTGENPHONE APN (Flashed a message stating unstable Network) and always automatically switched back to the Cingular 410 APN. I already paid $70 for the GoPhone Plan. Can anyone please help me get 4G/LTE on the GoPhone Plan? I tried different modes in the Hidden Menu. One of the LTE Modes did give me LTE and gave really fast data but all my cell phone bars went to zero. Is there any other settings or the Hidden Menu or APN Configurations that will work? TIA.
