4G connection drops out often. Won't come back for a while

I've been having an annoying problem lately. I'm running theory of ginger 4.2 and lately my 4G connection will just drop out and it won't reconnect for 5+ minutes. If I manually disable and reenable the connection it immediately grabs 4G back. It will stay steady for maybe 40 minutes and then drop out. This has happened on the MR2 and MR2.5 radios. Suggestions?

Mine does this routinely on a stock phone. Dunno if it's the network or the phone.
Dont know if this phone/network was ready for primetime

Mine just started doing this a few days ago.

So I flashed to CM7 on a froyo radio and I'm still having connection issues. How hard is it to get a replacement sim card? I think that might be the culprit honestly.

just call Verizon or go to a store.

Should I take cm7 off or just don't show them my phone.

i doubt it's the sim cards doing this... it's for sure the radio's. the mr1 radio on froyo drops my 3g to 1x alot, so did mr2 but mr2.5 was perfect for me. i just want a functional radio to ship this week.

It just started a few days ago, and a friend of mine with the thunderbolt isn't having the issues I'm having.

Mine started doing that last week while on Gingeritis final. I flashed all kinds of roms & radios (including Froyo) with no improvement. I even went to verizon & swapped sim cards, and still no better. I went back to bone stock and finally got reliable 4G again. Very frustrating

I've been having this issue for a couple of weeks at home but at work the LTE connection is rock solid. I think it's the network where I'm at. I went back to an old Froyo build and radio set and it was the same issue. I've tried every radio combo both GB and Froyo ROM's and it behaves the same way. At work no issue...at home I have to switch to wifi. It'll show LTE with bars (sometimes full 4...usually 3) and I will have activity on the up/down arrows and it'll work for a minute and then stop working until finally the LTE icon goes away and it goes to 1x (or even sometimes 3G and I'm in LTE mode.)

Its looking more and more like a network problem. Might as well save myself a trip to the Verizon store. Oh well, not that big of a deal I guess. Stand in line for 40 minutes for them to tell me they can't help.

Mine does this but I'm on the edge of the 4G signal where I live. I just lock in 3G and don't worry about it. When I get in an area I need to use some speed I turn 4G back on.

[Q] Rogers One X - Dropping off network!!!

This is the second handset I've received and is now experiencing the same symptoms. With the phone sitting on my desk at work it drops the connection to the Rogers tower and sits in NO Service state.
Has anyone else experienced the same problems with their One-X?
Q.

Yep, I get this too. I'm quite sure it'll be fixed in an update, but in the meantime I have switch in and out of airplane mode to fix it.

Airplane mode doesn't do a thing for me to get it reconnected. I have to reboot the phone. I also still get the 'preparing SIM' message now and then. Others have attributed that to Sense and using another launcher either fixed it or covered up the message from being displayed.
I am curious if there is a hardware issue with intermittent contact with the SIM card.

Hey guys,
I got my HOX on Friday last week and I've rooted, unlocked the bootloader network unlocked it so I could use it with Bell. I haven't noted those symptoms being on the Bell Network. Could be worth to check with Rogers.

I had tons of connection issues on Rogers....until I disabled LTE. Now I get full bars all the time and never lose the network. I used to get 1-2 bars max on LTE and I would randomly lose connection completely. I think Rogers LTE network just sucks.

Yeah I never get much more then 2 bars on LTE either, but the speeds are lightning fast

AWS has terrible wall penetration. This is why Wind Mobile and Mobilicity customers are always complaining about the terrible reception and dropped calls they get. Rogers uses the same frequency.

Interestingly enough, I'm not even on an LTE plan. Confirmed with Rogers today that I am still on my Captivate's 3G plan.
I never get the LTE in the notifications bar just 4G and my signal will go from full bars to nothing.
Another interesting observation -although it might have been coincidence, when I noticed I was in No Service I tapped the back of the phone like anyone would when frustrated and low and behold, it came back online!
The evidence of a hardware problem reading the SIM is growing.....2nd phone showing the same issue though ????, very odd.
Q.

I am using mine on att and I am experiencing the same issue.

i think the issue is the phone not reading the sim card properly. I'm the "preparing sim card" pop-up has something to do with it also

I am about to receive my rogers one x too and use with att. Do I need to setup apn myself for lte? Or do I need a new sim from att?

I have my Rogers HOX unlocked for Telus, I haven't lost cell usage but I do get loss of data connection all the time... I go into Gmail or YouTube and it says no connection retry.. Hit retry and it good.. pain in as but that's what I get for unlocking it...

My AT&T HOX is doing this too, network drops off and it gets stuck on EDGE.
Just started yesterday. I've had the phone since launch last Sunday.

Unfotunetly i have the same problem. i rooted my HOX (AT&T) to use another service. but my new service is not working properly, signal is always too weak. Is there anyone who knows to solve? HELP NEEDED...

This is weird I have had my One X for about two weeks and have never experienced a signal drop I've always been one LTE or a maybe for a few hours when I drive out to 4G or something, but never an actual drop. Not sure if this helps but I flashed the Asia Radio and I am using the Nocturnal xi40 rom.

Missed 4G upgrade... Question

I have the 3g version mz600...but I only ever use wifi... Can I flash any wifi only rom and it work?
I know I won't get data, but will work with wifi right?
Sent from my HTC One X using xda app-developers app

I don't know the definite answer but I seem to remember that no it will not work.
If you're trying to avoid mobile data use though just leave it on airplane mode?
Sorry

Not trying to avoid it... I just don't have a mobile data plan setup... I bought it to use wifi only. A lot of the new roms will be 4G or wifi only is what I read.

Wifi rom will work.

Yea, wifi rom will work... but no data!

i have a 3g xoom and missed the 4g upgrade due to being overseas. all i use are wingray (wifi only) roms now cuz it makes no sense to have the 3g roms since they wont work anyway (and it gets rid of the radio signal cluster in the notifications panel).
so, yes, wifi only roms will work with your 3g xoom.

No cellular data

Ok, after asking on various Rom threads to no avail I'm making a topic about it seeing as I'm not alone on this one...
I seem to have lost all cellular data. When I turn on mobile data I keep getting ' connection failed due to incorrect apn settings'
I have flashed different roms, re flashed current viper Rom, factory reset, full wiped, reset apn to default settings, even got a new sim from my service provider. My apn settings are correct, as have been confirmed by my service provider, I've updated radio and firmware...and still no mobile data.
Does anyone have the faintest idea what's going on?
Thanks guys.

Hi,
Have you tried deleting ALL your APN settings,rebooting,then,re-installing them?

Just tried your suggestion malybru, unfortunately it hasn't made any difference

I'm running viper too and when I upgraded to recommended radio this happened to me. I lost all data connection ! To restore my data I used one of the five(I believe it's 5) generic ics radio and matching ril. I got lucky first one I tried worked for me! I'm not exactly sure of your situation but it sounds very similar to what happened to me... You might want to try the generic ics radio with matching ril.it restored my data right away. You will have to do some searching to find it. But it's there. This just happened to me last week. I really hope this helps you! It worked for me... Best of luck.

Realsis, I have flashed all the available radio and ril combinations and still no luck. I have full signal and can make and receive calls no problem, sms too, just no data :what:

this problem seems similar to the problem i faced recently ..i would have complete signal ..but no data
in my case ..if i change the network mode to GSM only ..i used to get Edge
the thing which caused this problem in my case is... loose sim ..yes the sim is loose ..and i kept a paper on top of sim to make it fit tight ...and voila problem solved ...just try this ..it might work
:fingers-crossed:

also check in phone testing that you are st to WCDMA preferred
from key pad *#*#4636#*#* phone settings - look for the only drop down box - hit it choose WCMDA preffered then home

I even lock on wdcma only by pressing *#*#4636#*#* and go to phone information press your current channel and another menu will come up, choose your desired channel from there then press refresh. My device kept going to edge sand it drove me crazy so I locked on wdcma only
And had no problem ever since. I now stay on H. I'm sure it depends on your area also but I've never lost signal doing it that way.

What carrier are you on? There are APN settings that maybe incorrect or just got corrupted when flashing a rom.

I've reset my apn already and checked with my carrier (gibtelecom from Gibraltar) and they are fine, I've also re flashed my Rom after full wipe and still no luck

signal cuts in and out

i just flashed cm9 on my sensation and the signal keeps cuting in and out i tryed to mess with the network settings but i still dont get anything and i reflashed still samething
what should i do?

Okay a few things first...
When you say the signal cuts out...what signal do you mean? Cell, mobile data, or wifi? (Each has its own fixes)
Second, how long have you had the problem and did it start as soon as you first booted cm9? If it has just been a few hours and it worked on cm9 at one point, it could just be a network issue that is out of your hands.

Known issue in AOSP builds, wipe cache and dalvik-cache

Check your APN's.
If you have 2 or 3 to choose from, delete all but the one you actually need. You are on t mobile so assuming you do a normal monthly billing plan with a contract the correct apn is the one called t mobile-us. You may see one for simple mobile and something else too.
AOSP builds sometimes install multiple apn's at initial set up. Its usually not a problem for 98% of users as you are supposed to be able to pick 1 and have the others be ignored, but sometimes it doesnt ignore the 2 that you arent supposed to use and tries to connect to all three. This may not be what is causing your problem, but its worth a shot.
2 variations on this......
In one version your data will connect for a second then drop for 2 seconds and repeat indefinitely. That is when the phone is trying to use all the apn's.
In the other version your data doesnt work at all. This could be because you are locked into the wrong apn or the correct one had been corrupted/altered. If you have never messed with your apns this is less likely.
