Data drop - T-Mobile, Samsung Galaxy SIII

Hello,
I'm having issues with data drops that occur more or less randomly. They persist for many minutes at times or hours. I have found that restarting the phone temporarily fixes the issue.
I am running CM10.1 nightly from the first of this month. I have also updated my modem to the latest one on the modems thread, which is UVFLJA.
The drop happens without warning or slowing down, and the icon remains the same, insisting it is connected to H+/H or occasionally 3G.
Again restarting fixes the issue temporarily, but restarting every so often is frustrating.
EDIT
It's a Data only drop. I can text and send calls just as nicely. The phone also believes it is connected to the Tmobile data network though none is being sent.

This has always happened to me on Samsung phones. It's like the data hangs on upload and it won't download any data. When this happens to you, do you notice that only the upload arrow flashes?

Yes it does get stuck on upload. Sorry for the delayed response.

Data "stalling"

I don't really know to describe this problem better. I'm running CM10 (lately AOKP's latest build) with default kernels. I've flashed all the radios and tried a bunch of them in solid LTE coverage, I seem to have the same problem every time, which is the data seems to "stall."
It will show full signal, and then if i click a link, it will sort of just sit there, not really doing anything. Eventually it may load, or i give up in patience. Any one have any ideas?

I am using at&t stock rom and not yet rooted. Even I have the same problem. Tried to disable and enable data from the notification but did not help. But, when I turn on the wifi, and turn off the wifi again, it works fine. When wifi is turned on phone disables the data and try's to connect to wifi or shows the available networks, but I don't connect and I turn off the wifi, phone reconnects to the at&t data again and then it works fine. Not sure why.

I can't even run a speed test because it just sits there. Web pages "load" but wind up stalling. Sometimes they finish, sometimes they don't. I have no idea what's causing it. What modem are you on?

May be a good time to contact your cell phone provider for a replacement.
I was on a cross country road trip running CM9 on my GS3 and I kept running into the same thing. A temporary fix was to reboot the phone. Since I got back, I flashed SlimBean and I haven't seen the issue again.
In my case, I think its the SIM card. I used Google Maps/Navagation on my HTC G2 (using a micro SIM adapter) and my phone got HOT, I mean burn your fingers hot (upwards of 57 degC to 60 degC).
If it happens again I'm going to bring my SIM card back to ATT and have them replace it. I did some googleing and it seems like this is common with the Verizon variants of the GS3.

That's the next step... it means reflashing, and waiting for samsung to fix it though, which sucks a lot.
ive had this same problem and it would piss me off! i found out that busybox was the culprit. i uninstalled busybox and cleard my cache in recovery and all was well once again. if any of yall have busybox installed you may look into my solution.
I recently been having this issue also. But mine is a little bit different. Like my phone will say I am connected to "H" for data but when I load a Page it slightly lags switches to H+ and boom Internet works. When I stall for more then 5 minutes it switches back. I'm not sure if it's some battery conserving feature or what but I have no problem against at.

[Q] WCDMA Mobile data issue.

Hey everbody. this is my first post on here. and I have a really annoying issue.
OK, i bought an unbranded Galaxy Note II N7100 4.1.2 jelly bean couple of months ago and that issue seemed to be there since the beginning.
It's that when I'm connected to internet through mobile data on WCDMA, all of a sudden the "received" signal (orange arrow) won't flash any more while green arrow flashes every two seconds and i have no internet access no matter what i do, the only thing that can temporarily fix this is that i restart my phone and then the internet is perfect again for a not certain interval of time and then the issue happens again, it won't come back until i restart the phone again.
Sometimes it could stay for 12 hours before it happens and sometimes i could keep restarting my phone every five minutes, it's really annoying.
I've tried all the known tricks like hard reset, deleting all apps, i disabled so many services or apps that may cause this problem, I disabled all syncing apps, i deleted, re installed APNs, i changed my SIM card and finally i subscribed for another network provider and it still happens
I'm really at a loss, I don't know what causes this problem.
Is it a hardware issue? but if it was a hardware issue, it wouldn't work at all even after restart, right? is it some bug in the built-in 4.1.2 jellybean?
And i also may say that i receive calls normally, the WIFI works perfectly and the GSM mobile data works all the time no problems, it only happens on the WCDMA ONLY or the AUTOMODE.
The H , H+ or 3G sign is up there but the orange arrow all of a sudden won't flash and no internet access at all untill i restart the phone.and this issue may start to happen even if the mobile data is off all day and when i turn it on BOOM the issue seems to be there even before turning it on.
I hope you guys can help me with this...thanks

Flashing a custom ROM is really easy, and there is no way u can brick your phone if you do the steps correctly.

WIFI/Data Connection handoff issue

Hopefully I word this right so i can clearly describe my issue. About a week ago I had a glitch with a custom ROM (I am rooted and S-OFF). Before the glitch I had zero issues, data worked created, WIFI worked great, handoff between the two seemed flawless. This is where i am at now.
After taking an absurdly long time to actually be able to wipe and reload a ROM, the issue started. Run just WIFI, no problem, run just Mobile Data no problem, but once I connect to a WIFI ( have tried several WIFI connections and hotspots) this occurs. Approximately everry 5-10 minutes you can see the data connection momentarily drop then reconnect, giving me 3 notification sounds. Annoying to say the least. Doesn't affect the performance of the device but you can see how annoying that would be. I'm gone through all of the settings I can think of in Dev and in settings and can't figure out why it keeps doing this. I was originally told to try a radio but data is perfect if no WIFI present on the device so I would rather not flash and wipe if I can help it.. I know the simple fix would be to disable mobile data at home but that doesn't cut it I would like it to be on as it normally would be. AS a note I have tried full wipes and several ROMS they all present the same issue.
If anyone understands and can help, and you need a logcat I will gladly provide one.

Question Z Fold 4: Losing Network Connection When On Home Wifi (ATT)

Hello all!
Got a weird problem, that at first wasn't much of an issue. But now keeps getting worse and worse.
I'm on ATT btw
I've noticed that when I'm on my home wifi, I will randomly have the following issues:
I can't send or receive phone calls
I can't send or receive text messages
Anything network related just doesn't work
It's very random, but happens frequently, and if I turn on airplane mode then turn it back off, the issue is resolved.
I've tried:
resetting network settings on phone
resetting my home network
soft restart and hard restarting phone
I've tried connecting a router to the stock ATT router and using that as my connection
Everything I can think of, short of reformatting the phone completely which I will probably try later this week
I'm on the latest firmware
When the issue happens, I can turn off wifi and it will show 2-3 bars of network but no lte/5g/5g+ or anything. And sometimes it shows the circle with a line through it.
Thanks!

Are you using an e-sim?
I have t-mobile with an e-sim and i've had this happen before. Ended up just restarting the phone.

Nope, using a normal sim card from ATT.
Lucky a simple restart fixed it, I'm at wits end how to fix this issue....making work very difficult lol
Going to run phone without wifi today and see if the issue comes up off wifi.
Okay, so tested today without using wifi. And while not as frequent, it still did lose connection just now. And I had to toggle wifi off/on for it to regain connection....
Guess my last step is to reformat the phone
Just got the fold4 on T-Mobile and had the same issue over the weekend.
Randomly stops getting service, have bars but no data, sim says unknown. Disable then reenable sim and it works until next time.
Cleared cache, cleared network settings, remove and reinserted sim.
Today is my first day without losing network.

Interesting, going to try some stuff tomorrow to see what I can figure out.
I was away from my house and had no issues, so starting to think maybe it's my location....but not sure.
Interesting, I've been getting this occasionally on my fold 4 with tmobile. I'll have apps that wont update data with a 'you're not connected to the internet' error. I recently added duck duck go browser and enabled the app tracking blocker. I've been wondering if the duck go vpn is the cause. Do you use any sort of vpn?

Yeah I use ProtonVPN, used to use alwayson but ended up turning it off as it was interfering with my Tesla Key function. But whether it's on or off, I still get the issue.
I haven't reformatted my phone just yet, but the issue has reduced a bit the last few days. I'm not sold on it being my phone as this literally only happens while at home.....really bizarre honestly.
Also got an issue now with android 13 that it won't work with my Tesla half the time. It just doesn't recognize my phone as my key .-. really tilting xD

Thanks for the info. It's so intermittent it's very hard to pin down. I still haven't gotten the update to 13 so hopefully that helps you narrow your search some.

I've noticed it less with Android 13, but android 13 broke my Tesla Key functionality....so not sure that was worth the trade off xD
Yeah, I haven't been able to pin point any specific cause which is super annoying....
Well it lasted a day or 2 then happened a few times again.
As this was a new device for me, I noticed it wasn't "activated" on T-Mobiles site. I went through the activation process and that seems to have fixed it for me now (wifi calling too).
Likely unrelated to what you're experiencing but thought I'd mention it.

That's interesting though, maybe I just need to go talk to ATT as much of a pain in the ass as it is -_-*

Question ⚠️ Suddenly, The mobile data connection started to fail.

POCO F3
Suddenly, The mobile data connection started to fail.
It suddenly disconnects, and I have to turn airplane mode on and off to get it to connect again, but it doesn't take long, it varies, and the connection is lost again.
And when it's connected, it's very slow, but a lot, it went from a 15mbps connection (before the problem), to a .3mbps connection. I have installed several ROM'S, and nothing fixes it. Another thing I've noticed is that suddenly he also started using Roaming when he didn't have it before.
Update: Testing with another mobile, with the same SIMCARD, i can connect to my red 4G, but in this POCO F3, when i tried connect to 4g cant, I get a notification that the selected network cannot be connected, The only one that accepts me is the one with 4G R (I think it's roaming).
UPDATE: Also I think that is a problem of crash of the Band 28 LTE
My modem often crashes too, since I bought the phone last year. Standard ROM, no unlock/root, updates when FW goes out.
I mostly see modem crash when the phone switch from wifi to LTE to wifi to LTE etc when I go outside. At one point I notice I have no data connection, sometimes it displays the "no SIM card" icon, the modem program loops and crash and the phone becomes warm because of this and lose its battery real fast.
Only cure is to reboot the phone.
Hi, my phone just started having a very similar issue after working fine for almost two years. I am on T-mobile in US, where are you? Did you find out any more info on this?

The truth is that I never found out, what I did find out is that my IMEI of my cell phone had a report of theft (I bought it second-hand) and only 2 networks (from my country) grabbed me: "telcel and altán", of which altán only got roaming and only telcel got the original 4g, on the other hand "at&t and movistar", nothing, only the company detected me, but they didn't get a signal... No way, I gave up, I switched to the only one that if he caught me it was Telcel (even if he didn't want to).

A lot of people complain about modem crash since the beginning, Xiaomi never fixed it. It seems the problem is happening when switching cell towers/wifi. At one point you notice you have no data or the "no sim" icon, you have to reboot.
I was experiencing that a lot when I was on a MVNO for the major networks (Mint Mobile, Google Fi, etc.). Upon switching to AT&T Prepaid, I am experiencing far, far fewer disconnects. Some particular locations will give me the exclamation point, but by and large it's much better.
It seems everyone is torn in half, between this glitch being software related, or hardware related.
I have tried everything to blocking out certain bands with network guru, to taking my phone apart and looking for some kind of issue. Been through countless roms, and firmwares, and kernels. I've gotten a new Sim card too. Have tried Compressed air. with nothing seeming to solve this issue permidently.

For what it's worth, I'm also using a custom ROM (Arrow OS 13). I recall a while back there being kernels people developed that attempted to address the phone restarting issue.

Phone does not restart. It's just that at one point, you notice your data are not working, you cannot enable them, nor make phone calls, you may have the "no sim" account, your phone may go warm because the modem is constantly restarting.
In the end, you have to reboot your phone and everything is normal again.
As it about always happens while outside, I cannot connect a usb cable to dump logcat or others.

Try to put some pressure on the phone screen, not too much, push down slightly or press it together in your hands while holding volume up volume down and power button. Let me know if this helps

Were you listening to something on Bluetooth via mobile data?
were you driving?
What was the ambient temperature in the room or outside when this occured?
Just trying to narrow down hardware or software.
My poco f3 likes to reboot with the no Sim error, when I'm driving around on mobile data, listening to Spotify via Bluetooth.
I'm curious what circumstances other users have encountered this error in, or what they were doing at the time when it occurred
As it happens about only when I'm outside, I can be driving (phone connected in BT) or walking.
But my phone never reboots, never.
