[Q] Mobile data disconnects frequently, does not reconnect on toggling

I'm surprised no one else has faced this problem. Mine and 2 other Explorers I have seen have it.
The mobile data gets disconnected on its own. The 'E' symbol from the network icon goes away. But mobile data is marked as enabled in the settings.
Sometimes, toggling mobile data a couple of times does the trick. Sometimes I have to toggle airplane mode then toggle data. Sometimes even this doesn't work and I have to reboot the phone to get data to work.
This disconnection happens every couple of hours, so it is a real pain.
I am using cm9, I had the problem on stock too and on every ROM I have tried.
I have tried marking the network type to 'GSM only' in the 'Testing' menu (from 'GSM/WCDMA auto') as I read somewhere that this solves the problem. Still no luck.
Any help or suggestions would be appreciated. Thank you.

check if your apn is correct or not,
or try to use another sim card
are you facing this problem when you lock your screen?

I guess my apn is correct, since net does work normally (ie. when I'm able to connect). I have tried two sim cards, and know 2 other people who have the same problem, one of them uses a different operator.

Not necessarily, sometimes it goes off while I'm browsing etc, and then just won't come back on. And keep data always on is enabled in settings, and I don't use any battery saving app.
Any idea what the problem is?

Which rom you are using now?
Check if you have data connection or not.
Did you try to connect internet using the same sim card with another mobile
If another mobile connects to internet then reflash your ROM or try another ROM
hit thanks if helped

/QUOTE]
I am using the unofficial cm9.
I have data connection right now. I have used this same sim with my Nokia phone before I got my Explorer without any issues.
Maybe it IS an operator issue, but then there should be many complaints from India about the same thing right?

whenever i flash new rom
data wrks fine
bt persinally i hv seen that wen i install twitter
it behaves like ur prob n dsnt mtter if i uninstall it
it kps on dscnncting randomly until i flash new rom

it's a network problem, I had the same issue once so I called the network service centre & they told me that they were upgrading the system & recommended me to use the data plan after few hours.. so after few hours I called again & they confirmed that the problem was solved..after that till now I have no disconnection issues.

With BSNL sim card, I have helped so many friends connect to internet properly by creating an APN "bsnlnet". By default HTC and all use the old APN (gprssouth.cellone.in). That connects for a while and disconnects.
And Nokia phones automatically receive a configuration setting message from BSNL but Android doesn't.

I've used cm9, cm10, cm10.1, aosp, aokp, jaggy, cm10.2 weekly. It's the same with my TATA DOCOMO sim. I ported to vodafone and with the correctly configured apn settings, its working great. It's definitely a provider problem and has been for the last 2 years.

[Q] No Data and Wifi data transfer (but connected))

Hi guys,
I'm using moto g for about 2 weeks and everything was fine until yesterday. I will try to explain what I've chronologically. My phone isn't rooted. Android 4.4.2, 174.44.9.falcon_umta.Retail.en.GB, KLB20.9-1.10-1.9
For last few days I was testing some battery stretching apps, such as Juice Defender, 2x Battery, GreenPower and maybe one more, but I don't remember the name.Finally I've bought Juice Defender Plus as that app was something that I needed (control mobile and wifi in an intelligent way, but that's not the point). Before JD I've uninstalled other battery aps (but without reverting their settings to defaults). Then I've installed JD, configured it and started to learn JD with my wifi network, whatever.
Next day I went to work and I'm not sure if mobile network was working or not, but wifi network was ok. Updates, synch, etc. was working well. I've installed 2-3 new apps (don't remember, but it was camera360, total commander with few plugins, and maybe something more). Then I've left wifi network, entered car and connected with mobile network. From this point everything stopped to work. There was no connection to any site, no synch from google, weather, and so on. Icon on top of the screen informed me that connection is online (with H or H+, sometimes worse, but probably it doesn't matter). I've tried to connect with many apps to Internet, but none of them succeeded... I thought that maybe there is something wrong with mobile and after that, when I get back to wifi coverage, everything will rise and shine.
Unfortunately when I get back to wifi zone, phone found new network and connected to it. It doesn't matter what network it is, because few days ago I was working with that wifi net and more on that, laptop connected to that network works like a charm. As I said, connected, data transfer in 3g watchdog shows very little net usage (about 200-300B/s). Can't load web pages, can't sync. The same behavior as in mobile, there is connection, very little data usage, but nothing more, no web pages, no sync, etc..
I've restarted phone many times, entered in airplane mode, removed, cleaned and inserted back the sim card - none helped. I've checked ip, gateway and dns which came from dhcp router in wifi network. Everything was fine, addresses were the "same" as my laptop (beside ip address, which was different). I've checked what's up with JD, then I've disabled it, uninstalled..., checked transfer limit for mobile, turned on and off mobile, wifi in many ways. Checked proxy in browser (chrome).
The result was always the SAME.
in chrome: entered address, page starts to load, nothing shows and stalls, after a little while (tens of seconds) there was a message telling me something like: page is unavailable (I can't remember the right message).
in gmail: sync lasts forever, when I send email (to myself) it popups message about sending, but it disappears in a while, a no new email...
other apps, for example, weather on main screen, sync could last to eternity, and no new data.
Today, after whole day without wifi coverage I went back to wifi zone and tried to connect to it... and all emails, sync, whatsup and so on, updated. I think that, I didn't change nothing, but why wifi started to work? I don't know.
I've checked if mobile Internet works as it should, but without any positive results. In mobile there is the same problem as for a last 2 days...
Does someone know any solution to my problem?
PS: I've even tried to enter ip address of wp.pl host, and then phone redirected me to address: 194.9.223.70/ns/cs/deny.html?trx=...something&tpd=3&ts=somenumber&sid=HTTP_DRSTD&url=...mobile[dot]orange[dot]pl

Are you able to send & receive calls? Have you checked your APN as well? Wondering if one of the apps you've tried has changed a setting or set itself as some kind of proxy that your phone's still trying to use even though you've uninstalled it.....not sure......had a similar experience when I tried out a firewall app & removed it without disabling the settings it applied. Can't think of anything else, sorry mate

Yes, sms and calls works fine. APN is okey, moment ago I've sent configuration sms for internet apn from my operator. I know that it could be one of my apps, which I've uninstalled, but I don' know which one it was .

Might be worth checking device administrators in settings as well just in case the culprits there? Good luck

Checked that, there is only Android device manager (sorry, maybe there is another translation, I'm not using EN lang in my phone) enabled. The rest dev admins are disabled.

Factory reset. That way you start from scratch and if still a problem you can rule out any apps or incorrect config etc. Its the easiest way to narrow down the issue.

maybe it's the easiest way, but I think it's not an option if I want to know what was wrong...

Sounds like one of the apps is the problem, as you already suspect. You may have to concede and do a factory reset:
Settings > Backup & reset > Factory data reset​

Please make some effort... factory reset is not the first thing to do when sth is wrong.

I suggested a factory reset as this then rules out all apps and config you have setup. If the problem still happens after a factory reset then you have narrowed down the problem a lot. Possibly it will just fix it though.
However if you want to find the cause of the issue then factory resetting is not the best thing to do as you say. But you seem to have installed a whole bunch of apps in a short space of time so even if you find the problem I doubt you will be able to find out why it happened, ie which app caused it.
You will maybe fix it but never know what caused it or how to prevent it again.
If you factory reset and it fixes it you can take things more slowly this time, is install apps and configure more slowly until you hit the problem, then its easier to see what caused it.

As there was no chance to get other suggestions than "do factory reset" , I've made factory default. Unfortunately, without any change in my problem. Right now wifi works fine, but 3g/data is dead. I've checked my sim card in another phone and 3g/data didn't work too. So I've called to my telco and heard that everything is ok, but probably my sim card is damaged and that's why my data connection is dead. I will try to get new sim card tomorrow.

So those of us suggesting a factory reset were correct then. Had you not reset you would have spent wasted time trying to fix what now appears to be a sim card error. Possibly best not to tell people to 'make an effort' when they are trying to help.

[Q] Very strange mobile data issue

Myself and my partner have recently purchased an Xperia Z3 each running Android 4.4.4 and love it but experiencing a very strange issue with mobile data.
Periodically on both our devices we lose mobile data (no 4G, H/H+ symbol) despite have a good connection. A phone restart fixes the problem but this happens all time and usually when reception is lost and then rejoined. Turning airport mode on does not fix the issue.
We are both on the UK Three Mobile network and have entered the correct APN settings.
Very strangely I have discovered the if I change just the "APN" entry to any random text then go back to mobile network settings the data instantly appears and works again for a period of time! This saves a reboot but the issue returns again once reception is lost The official setting for apn is "three.co.uk" but the issue still happens. Very strange that changing just the apn name to anything random fixes it for a bit.
I'm hoping the lollipop update fixes this issue but not holding up hope, any suggestions, or has anyone seen this issue? I suspect this a network issue but have already changed sim cards with no luck.
Also this issue occurs regardless of location and on both our identical devices. Have carried out factory resets too but no joy.

I dont think device has any fault..if ur device is unlocked u can try another sim card and see if issue persists..
U can try deleting all apns and download via settings menu...amd try..

Thanks for the reply, have tried removing all apn settings and re-adding but no luck
Our phones are factory unlocked so will try and test with another network sim, if I can find one...
Wish the lollipop update would come out already so I can test with that.
Cheers

LG G5 Sim not detected only for SMS and calls

As stated I'm using the LG G5 H830 T-Mobile variant. I am getting 4G LTE data connection and everything runs well (Not in any WiFi range) Yet for SMS and calling as well as mobile hotspot I get "No USIM card' error. This happened after wiping the system and formatting data. Rebooted recovery (as per instructions on forum) then installed the stock firmware & Patch with systemless root and xposed. After this I did factor reset when just pulling the sim didn't help. Still nothing. I reflashed just the stock firmware with TWRP and SuperSU and issue is still happening. I've disabled rebooted and enabled the phone radio. SIM is in good condition and tray as well everything is SECURE and should be good to go.
I'm assuming a new SIM might be a solution. But I'm not counting on it and with Labor Day tomorrow for me I wouldn't be able to pick one up for 2 days. So here I am...hoping someone might have a fix. I know I don't have many posts on here. But I am an experienced user....just not with the more basic of problems I guess
Thanks!!

Has anyone else experienced this yet? I'm just curious...I had it fixed for a couple days. I've formatted data and done complete system wipe. Tried it resetting phone with the COMPLETE zip and TOT using LGUP. I'm receiving texts. Not calls. Not able to send either. I've activated new sim, didn't help. LG support just told me to look into warranty. T-Mobile needless to say just wanted. Sim card does show stock tmobile short code contacts but phone number shows as unknown. Hotspot won't work. I've tried setting the phone number to the sim. Nothing.
Anyways. I don't think I messed with anything, even so I've done everything to start the phone from scratch. Going to replace it, just more or less curious at this point and maybe others have had the same issue.

I believe I had the same issue as you and it was driving me crazy. I was constantly wiping data, system, etc but my phone kept giving the message "roaming indicator off" where it should show the name of the carrier. This resulted in me having LTE data and that's it- no 3g, no phone calls, etc. I couldn't even access the mobile network menu.
What ended up causing the issue was the network mode setting under wireless networks. Keep in mind at this point I'm running a patched rom which now gives more options in the network mode menu than the phone came factory with. I have an area at work where I have to switch to 3g, GSM/wcdma preferred network setting, because although I have full LTE signal, my connection goes dead. When switching back from 3g I chose the setting lte/CDMA thinking this would force my phone to stay in lte mode due to another area on an upper floor where the phone will constantly drop lte.
Anyways this resulted in my phone saying roaming indicator unavailable, the inability to make or receive phone calls, and either the mobile networks or network mode menus being grayed out. When stuck in this mode there is no way to put the phone back into the standard "GSM/wcdma/lte" mode. Even a complete reflash won't fix it. I even used lgup, which worked for maybe a day until it force closed the phone app and went back to roaming indicator unavail. I wiped every partition and even reflashed radio firmware. Nothing worked.
What ended up fixing it was using an app called v10 hidden settings which allowed me to access the network mode menu directly and re-choose the lte/wcdma/GSM setting. Incidentally on first access to this menu through the app there are only two network settings available. Once you choose a GSM setting, the rest appear.
I'm not sure if this was your issue but I hoped this helped because this took me about a week to workout.

Mobile network internet access stopped working

Yesterday was like any other day, I took the bus to work and enabled mobile hotspot on my Oneplus 6 so I could do some work. On my way home in the afternoon, I did the same thing. This time however, I had exclemation marks on the mobile network symbol in the statusbar. Tried enabling hotspot anyway but there was network. Rebooted the phone but still the same issue. Oh well, I thought it was just my carrier then. When I came home to my wifi, I checked my carriers status information on their websites and there was no disturbances. Then I restored a backup which failed and I had to reflash the phone entirely with the latest pie zip. Today, I still don't have any network on my sims. I use two sims but they are using the same carrier. I also asked around my friends which has the same carrier and they have network...
I would understand if something might have happened when I reflashed the phone last night but that does not explain the sudden malfunction of the network on my bus ride home, the phone had worked flawlessly for a whole week.
This thread seem to be about the same thing and I tried the solutions regarding clearing caches and settings but it did not work:
https://forums.oneplus.com/threads/...ot-working-but-network-bars-are-there.844978/
Could it be something with the IMEI number? But it doesn't explain why it stopped working out of the blue. I can see both my IMEI numbers in the settings and I have also tried install Magisk 17.2 beta as suggested by another user. I think I still have a backup of the modem on my pc. However this is from when the network still worked and then suddenly stopped working.
TLDR: I have full reception, Calls and SMS work, there is just no Internet connection.

Just to be sure, datasave is turned off?

Yep, that is off. I have also reset my APN setting and double checked them with my provider, it didn't help.

No hotspot
I'm having a similar issue, I updated to android p stable and since then I can't use hotspot. It turns on fine and says devices connected but internet doesn't work on the connected devices. This seems to be an issue with Android P because my gf also has the op6 and I tried hotspot on hers before updating and it worked fine, then updated and it stopped working for her too. I have also tried clearing cache and manually entering the APN. I need to be able to tether to my laptop and tablet for work so anyone solution to this problem would be highly appreciated.
Thanks.

Although the problem I decribed in this thread isn't the hotspot problem, it was caused by my carrier. But I also have issues with hotspot, my laptop has trouble finding the wifi from the phone.
