Hi -- I've got an unlocked Kaiser 100 which works fine in other countries (SFR network in France, O2 in Ireland, etc...) and _has_ worked fine on AT&T in America until recently. Suddenly, the data connection has started randomly but chronically started going dead on me. The problem has nothing to do with connection strength: I'm in Manhattan, which generally has excellent coverage, and the connection can be at four bars on HSDPA, and I still won't be able to download _any_ data. Sometimes the four bars HSDPA icon will suddenly change to the no-connection icon for a moment and then return to four bars HSDPA again. And this happens completely unpredictably: the connection is sometimes fine for hours and hours, while at other times I won't be able to download any data for minutes at a time.
I've tried many different connection settings, some with proxy and some without, and haven't been able to fix the issue. AT&T support has been, of course, completely useless, and just stay that these problems happen with unlocked, non-AT&T branded phones.
Does anyone have any ideas? I'm using the stock ROM that came with the phone (and which worked great with AT&T until recently) and I've tried doing two soft-resets, neither of which have fixed the issue.
Thanks!
Alan
p.s. Does anyone understand why a "search this forum" search for ATT or AT&T turns up _nothing_? There are many posts that mention AT&T, obviously, but I can't find any of them doing a search. I wonder if someone has posted on this issue before, but I have no way to find out.
You didn't disable anything with an adv config tool by chance?
You are sure you covered "disable proxy"?
Settings:
Name: MediaNet
Proxy settings: None and "This network connects to the internet" marked
Access point: wap.cingular
Username/password/domain: LEAVE BLANK (don't ask why just leave BLANK)
Adv settings: User server assigned IP address
IP header compression
Servers: All empty
I had a similar issue a few weeks ago and AFTER removing username and pw all worked out well.
Thanks for the response -- yes, those are exactly what my settings have been too. They seem to be working fine right now, but I'm sure I'll have connection issues again later today or tomorrow.
Thanks!
Alan
Thank you for that. Telling me to delete my UN & password in media net settings. For some reason, that has saved me from wanting to destroy my mother ****ing phone.
With the UN and Password in there, my phone (when in use as modem for laptop) would ONLY allow me to run google searches, and visit the paypal website. Note, I couldn't actually click on any google result, as it would then resort to error 404
Thank you again, for lending me the tip that makes my phone work like it ****ing should have out of the goddamn box
I'm having data trouble as well. Everything worked fine as of last night. However, this morning I found that I could only connect to the Internet with Internet Explorer. Other browsers, Opera Mini, Opera 8.65, all hang. SiriusWM5, SelectRadio, Resco Radio, youtubeplay and other Web-enabled programs can no longer connect. However, QuickGPS still works as does RSS Hub.
I've tried to tinker with the connection settings, including using the advice in this thread Nothing works. I ran connection setup to just restore the original settings. Nothing. I can only connect with IE...I'm posting this message with it. Any ideas on what the problem might be that would allow some apps to work and not others?
UPDATE: Opera 9 and Netfront 3.3 actually do work. Live Search works also.
Is Pocket Outlook working? I just called AT&T because mine stopped working today.
It looks like this is a widespread problem. Mine is doing the same thing. At least we know it is the service and not the phone.
Hust saw this post on another website..
"Just got off the phone with an AT&T Rep. The hurricane knocked something out and the data access is supposedly down in half the U.S. ETA was this afternoon per the rep"
good to know. but why would some programs work and others not? don't they all use the same port/server/whatever to access the Web?
this is still weird. but let's hope it's fixed ASAP.
seems they've fixed the problem.

Cannot explain how a network works in three words but services to support whatever network (DNS, routers, proxy's, NAT servers) are spread all over the US so if a major hub or datacenter has a problem, things go south, at least partially.

Yeah, looks like things are working now.
I've run into a similar issue except that my phone works OK in the US but not in Germany.
I have an AT&T Tilt with the latest official AT&T Windows 6.1 ROM. It works great here in the US. However, when I am in Germany, the data connection seems to drop and the only way I found to get it back is to do a soft reset. It then comes back for a while, but drops again after some time (maybe tens of minutes - there's an X next to the data connection symbol). After the soft reset I am able to connect to download say the weather in the built-in HTC Home. However, after several minutes the connection drops again and checking the weather results in the phone trying to establish a data connection followed by a message that the answering modem has dropped the call.
Anyone know what the problem might be? The issue seems aggravated while connected to Vodafone, less so when connected to O2. After returning to the US everything works as expected again. I haven't done any tweaks to change the data connections of the phone. KaiserTweak sees everything related to GPRS and data set to default. Some people have suggested getting a new radio ROM, but I'm not sure which one would work well in the US, Europe, Japan and Korea.

I have a CAB in the office for intl. data setup. Helped me in Europe all the time, will post tomorrow.

I will try selecting the carrier when I am in Europe next week. However, I'd prefer something that just works in case a particular carrier is not available. I am hoping the radio will work OK in Korea and Japan too.
tyguy: Do you know what the cab changes? Does it change the radio ROM code or does it modify some other settings? I'm curious as to what is causing the problem. Also, is this a one time operation or do you have to keep changing settings when you go between continents?

Would you have it available now? I'm interested in trying it out. Do you have any details on what it actually does?
@emuyshondt
You're not forgotten. I do not know what it does but it worked for me in Europe.
I deleted it from my email since a buddy of mine sent it while I was in Europe and didn't store it.
Let me poke around - I'll come back to you.
Here it is.

Thanks! I'll try it out this coming weekend.
Lemme know.
I have a weird problem with my AT&T galaxy tab. For the past couple of days, each time I launch the Market, my 3G connection is killed and I can no longer access the network, and of course I cannot access the market. As soon as I kill the market app, my 3G connection comes back.
I cleared the data and cache of the market app, did not solve the issue. When I uninstall the updates of the market app (reverting to the original ugly market app), everything works fine, but it then automatically updates itself and the problem comes back. I assume this is a problem with the market app itself and not my device (hopefully).
Has anybody else experienced this issue and found a fix?
I am running stock ROM with third party apps installed enables (done it with superoneclick: root, enable third party apps, unroot).
I have the amazon app store installed, so I can still buy new apps, but I would like to be able to get updates for the apps I have purchased from the market.
Any help would be greatly appreciated.
Thanks!
What modem are you using? Does the problem happen when you are using wifi? I think the JMF modem that is available for overcome rom is weak and I get many dropped connections and slow data speeds.
I am using the stock ROM and stock modem, I have never flashed a ROM. It only happens with the Market App.
Same issue for me. I have a rooted stock rom.
I have the same issue. Also stock rom and rooted. When WIFI is on (and connected) the market works fine.
I have been beating my head against this since I bought one. I am rooted using....I think I used Super One Click......stock everything else with non-market apps enabled. I originally thought that Root had broken it; however, if I unrooted, reset to factory, I still had the issue.
After many hours at the ATT store and on the phone (and swapping the device once and SIM card twice) I had an epiphany. a Factory Reset does NOT wipe the Internal SD like I thought it did. It leaves /mnt/sdcard/ intact. So, just for kicks, I began looking at my folders here. I MAY have discovered something. Market started working after I restored this folder to it's factory content (deleted any folders having to do with Apps in general).
I can typically hold power, deactivate Data connection, wait a few seconds, re-enable, and I get 3g back (at least for browser and other apps, Market still fails).
I have PSX4Droid installed (PSX Emulator if you don't know). There is a folder here named /.psx4droid, so I renamed it to /psx4droid (If I remember correctly, doesn't the "." hide the folder......too long since Linux class). I then deactivated/reactivated my data, and the Market started working properly.
I am not sure if it has to do SPECIFICALLY with psx4droid or just the "Hidden" folder in general, but now my Market works. I have 2 more folders in this location (/.downloadTemp and /.FileExpert) that may/may not cause any problems. I will post my findings.
.....Okay, so I'm going to type what I write now....Market just failed. Now I'm renaming /.FileExpert....Let's see what happens......
Damn. Still fails. But I'm tellin' ya. There is something in this folder causing it.
Or maybe some app is causing it to break......I have Amazon App store installed, what about you guys?
I do have Amazon App installed.
Anybody with an AT&T Tab not having the issue?
Same issue here. I had the Amazon Appstore installed but uninstalled it probably a week afterwards. Rooted running stock, everytime I go into the market it crashes the 3g. I found a folder in sdcard/android/data that had a bunch of appstore files in it. I deleted that and still having the same issue. I have removed all 3rd party apps so I have no idea what is triggering this. Please help.
P.S. I can access the market on WiFi
This also happens to be sometimes, if you tap wifi on then off again your 3g should come back and work fine.
swyped from a galaxy far far away...
Unfortunately what you proposed did not work. The market is killing the network connection each and every time. The network connection only comes back when the market app is not active anymore.
Since everything works fine when the market upgrades are uninstalled, I really think it is a bug in the newer version of market. Hopefully, the next update will fix this.
Maybe when Gingerbread is out!
I'm thinking this has more to do with us having installed amazon appstore before it was supposed to be. Somebody is mad at us
Has anyone made any progress on this situation?
Sent from my SGH-I987 using XDA App
I really wish I would have made more progress. After all the trouble I had with the device with this issue, I was seriously monitoring the apps I installed and then testing the Market. I gave up after a while since I am on Wifi 90% of the time and hardly ever do I access the Market while driving. I still have a feeling that something in /mnt/sdcard is causing it. Like I had mentioned, I could wipe back to factory and the problem was still there. I seem to remember that it only started working proper after I had cleared this location of crap. I would think that a Market update would see a larger group of affected tabs than just a handful of us. This doesn't seem to be a widespread issue.
That being said......I have decided to move on to Gingerbread. Maybe that'll fix it
Hey guys, try this. Worked for me and my Data problems with Gingerbread
http://forum.xda-developers.com/showpost.php?p=13751694&postcount=6
Basically create a new APN inside Settings -> Wireless and Networks -> Mobile Networks -> Access Point Names. Only set the APN to "Broadband," save it (Menu button) and select the radio button for it. Instantly fixed my data issues.
Thank for the tip. Unfortunately, it did not work for me. I am running stock 2.2 and waiting for the official 2.3 update from AT&T.
Good Luck. I thought about waiting for the official.....but I also have a Captivate. We didn't get 2.2 until MONTHS after the rest of the world (I think it was like 5 or 6 months later). I didn't want to wait that long again.

Could you please report if the problem fixed with Gingerbread ?
At first I didn't have ANY cellular data until I created a new APN mentioned in the tagged thread (APN Broadband). Now I have no issues with Market. I wish I could trust AT&T to release Gingerbread in a timely fashion, but I know better. So instead, I flashed Overcome.
P.S. I really can't enough of the CRT lock animation......damn I'm such a geek....
Hey guys,
First of all, sorry but I'm a complete newbie with this phone, however I've tried to do the necessary research and I think i've hit a block. First of all, my phone is a SGH-1747 (from the title) Samsung Galaxy s III 4G LTE or just Samsung Galaxy s III LTE which is network unlocked with original carrier being AT&T. I updated the phone to Jelly Bean 4.1.1 via Samsung Kies and everything went smoothly. It was originally my aunt's and I asked her to ship it to me here in Australia. So my current provider is Vodafone Australia and yes I do have a micro sim and can use the phone for almost everything except for the problem that I'm experiencing.
Okay so firstly I thought my problem was that everything I go on google play store via my mobile data (not WIFI), I was unable to update / download certain apps and it would give me a "package file is invalid" error. I've done researched tried clearing cache, cookies, data but nothing seemed to work. I also thought it might be something to do with only unable to download apps that are a certain size, seeing as I could download SOME smaller apps (like google apps updates, but not all) but it got to the point where I tried accessing apps that require an internet connection, and it won't load because of error "not connected to internet or you might be disconnected". At all times I am able to access the internet via internet browser and even search for apps via google play store. I also thought it might be app-related, so i tried different apps, no bingo. I can however download all these apps / updates when I am connected to WIFI at my house, can even access the games. Also thought it might be related to Vodafone not supporting 4G so I tried to change around the network modes but It didn't really make much of a difference... I've also tried factory resetting many times with no bingo.
So now i'm at the point where I don't know what's wrong with it. Do you guys have any ideas? Even vodafone people were unable to find a solution after spending about an hour trying to fix it with them.
This forum is for the i9300, nothing on here will work with your phone
Hi, I desperately need some support as my device refuses to sign in in both Youtube and Play Store. I'm therefore unable to use both these apps. An error message keeps saying I'm offline and proposes to retry, but it simply never works whatever I do.
Issue has been going on since many weeks; I googles and tried many suggestions without any success.
Before I do a hard reset, has anyone an idea what this can be?
The amazing part is that my daughter's tab (Galaxy S2) is also having the same issue since some time! She has her own google account. What the heck is going on?
Thanks!

This may be an bug in the updated version of google play store or YouTube..Have you tried to sign in specific apps usning another google account you have..Also try to clear cached data of phone as well as clear data of those apps* you can also uninstall updates of those apps and force stop or disable them and after enabling again try to access*..Also might be network related issue sometimes weaken network shows such type of errors..Try to acees with high speed wifi or data with maximum signal..Even if problem exist then simply reset is last option for you..

Hi, I tried most of the solutions you're are mentioning, without any success. What I find interesting is what you wrote about weak network. I cancelled my cable connection at home some time back and using instead a 4G modem. Could that really be the culprit, knowing the coverage is medium? It sounds to me strange that such possibility exists, also I often go out and have full 4G network for hours sometimes and still it doesn't work. Interestingly enough, every about once per month it suddenly works, and I'm able to update my apps and also access my account in Youtube. It'll work for 2-3 days, until it's again the same bad. Really boring and would love to understand this issue better so as to possibly fix it. Thank you.

1)It's possible sometimes your networks proxy enforce your google id not to be sign in into specific apps you have mentioned and yes sometimes low network coverage also causes the issues like offline or sign in errors like please check network connection due wireless functionality limitations
2)I am curious about one thing if you have tried almost all the solutions found on google as well as your own, is it that much impossible for you to make backup of your current imp data and give a try to hard reset?? If i am not wrong, please give it a try because sometimes software glitches also causes the app crashes or network errors
3) Next thing sometimes your stock software gets corrupted due to some fatal malwares so many system apps as well as third party apps pretended to show errors like unfortunately process is stopped also some network related issue, so one solution you can try is to re-apply or update your current stock firmware..i.e. if update is unavailable you can fresh install same firmware version again on your phone which most of the times resolves the issue
4) As i mentioned in my first post you should give a try to any high speed mobile network like LTE or 5ghz band Wi-Fi which gives constant access to internet connection which probably help you to figure out exact issue i.e. with modems or connection your using or with your device itseld due to corrupted software
5)Please mention your device model no,country,your mobile network provider information so that it would be easy to figure out your issue
Thank you. Yes, a hard reset could solve it although I'd like to avoid it if possible. I will try ASAP on a solid wifi and see. I forgot to mention an important point: my daughter's tablet (Galaxy S2 pro) has got the same issue, and it started near about the same time like it did to me. She has her own Google ID, and she uses a different set of apps. Will report whenever I can test on a wifi.
My mobile provider is Salt Mobile here in Switzerland, and my Note 5 is a generic one bought in UAE. I run Dr. Ketan rom of about 8 months ago.

1)Ohhhk now i got, i assume you might be using Indian Variant with indian mobile network providers as per your username 'prerna'
so your device might be factory unlocked SM-N920C
2)So you should try on any faster network provider or incase wifi to check if problem is due to weak singal strength or specific with your device software integration
3) And i think you should give a try to dr.ketan's nougat rom which is based on latest nougat firmware which will might help you to overcome your issue as new base,new kernel will help you to get stable connectivity
4)If your running dr.ketans MM 6.0.1 based rom then download latest N5 nougat rom to flash
5)I know u might not new in flashing custom roms ad your running a custom one only from 8 months but once again be sure to enable 'oem unlocking' and 'usb debugging' options from developers option before flashing latest twrp version(Don't worry u can flash dr.ketans rom using any 3.0 twrp version ur running now but if latest version with stability and improvements available for your device then you can install it as per your requirement) if your running old one or before flashing nougat based N5 rom by dr.ketan
My much-loved, rooted, V40 405QA with latest and last stock Android has worked great on Verizon since the 4G changeover forced me to move from ATT where it could NEVER make voice calls.
I should say that it has worked great until the last few months and I think this change is due to Verizon's final sunset of CDMA - which is supposed to have been completed 12/2022.
In the last few months I find that the voice/sms network is often on EMERGENCY only (not true of the data network which seems to recover just fine) - even if it was fine only a few minutes ago (in a different location, usually). And this can ONLY be remedied by rebooting the phone. You can see this in the phone's radio details (hard to get at as the normal settings UI has no link to it - but still possible in a couple ways).
It appears that this happens any/every time that the phone has network contact but looses it. This can be caused by passing through a dead zone or by turning flight mode on and then off. It happens every single time! And again, the only "fix" I can find is to reboot. This is clearly unacceptable.
It is NOT Verizon or my SIM. I have tested moving it from by V40 into the wife's Samsung S8+ and it does NOT do this at all. So it has to be something about my phone. Additionally, I put a T-Mobile SIM in the V40 and it does the same thing - only worse because T-Mobile coverage is so crappy where I live and it is almost one BIG dead zone.
I have tried all the network preference options to see if changing them has any influence. It does NOT. So I am really stuck here.
So:
1. Are others seeing this problem?
2. Are there any known work-arounds?
I really appreciate the time and any help.
I have found, by accident, that the issues reported above DO NOT occur if the phone is in Safe Mode.
This makes me think that some mod I have done via magisk, LsPosed, etc is the source of my problem.
Sadly, I cannot get at anything while the phone is in safe mode. I would try to use adb but this damn phone has long had issues with USB connectivity - described elsewhere. I have tried to make my terminal emulator or rooted file manager into system apps hoping that if they were I could use them within safe mode. But that doesn't work either.
I use Magisk all the time without, I must admit, understanding much of what it does or how it works. It just seems to... But now I really think I need to be able to get at files that Magisk seems to "protect" in the system as I suspect what I need might be in there. I have no idea where Magisk puts/keeps all this. I will post in the Magisk thread but thought I'd mention it here as well.
Thanks for any suggestions.
