Hello all, i have had my HTC sensation 4G (on Bell) for just over a month and a few days ago i started losing my connection to the network intermittently. Super annoying. Anyways i tried deleting some recent apps, figured that might be the issue but nope didnt help. It happened about 3 days in a row until i finally did a Factory Reset on the phone. It worked fine for a bit and then began stopping its connection to the network. Anyways super frustrating, i read some forums about tunring ciphering on and off, i tried that didnt work... needless to say im chapped.
Sorry for the length, but basically wondering if anyone knows how to fix this as its to late to return the phone and i have read through similiar forums on other phones
sorry to hear abt ur problem. i experienced the same thing but i think mine was triggered when i installed juice defender. it would turn off mobile data when the screen was off and when i went to use the phone, i didn't have a connection. i uninstalled the app and did a power cycle and that seemed to fix the problem after i went back into settings and checked the box to turn mobile data on.

This. The phone seems to have trouble (on the stock kernel at least) when switching data from wifi only to cell when cell is turned off. This happens to me when I use wifi calling. The solution I came up with was to connect to a wifi network then turn on mobile data in the quick settings manually. Works every time for me.
HTC really needs to fix this.
Under mobile network in wireless settings, enable always-on mobile data.
This somehow fix my connection whereby it hampers with JD app by not turning on when it needs to.
Thanks for the help guys. I did also recently install a "battery optimizer: in Droid Utilities or soemthing like that, although i did a factory reset. ill try and do a full battery cycle like you mentioned and see if that helps
so the phone worked fine on the weekend, and even friday and i thought it was cause i stopped using a non "htc" charger and got rid of Android Utilities. but now its Tuesday again and like clockwork at 1pm it just stops connecting, if i reset it i get network for a few minutes and then boom out again. Very frustrating mid work day to be without my phone for hours on end. Dont know what to do.
Are you using WiFi at the time it goes out?

No i havent been, not allowed to use private phones on the corporate wireless, but so far i havent found a problem with it switching between wi-fi and H+ while at home.
I have a feeling that Bell Canada may be updating the network or something in the area but they havent said anything both times i called and i asked. so who knows. Its just to much like clockwork for me to think it would be the phone, but who knows.
So i believe i have this figured. I talked to tech support once again yesterday and i point blank asked if it was network problems he said no (3rd person from bell to tell me this) then reccomended i get a sim card change if that didnt work he said send the phone in for repair.
So i went to the downtown bell store talked to the girl, explained why i needed to replace a brand new sim, and she told me that it was because Bell doesnt have towers downtown they share the Telus towers, however because of network bottleneck bell users get less priority and thus i cant use my phone... Not only is this unnacceptable for a phone company to not provide service DOWNTOWN in a major city but having denied it multiple times forcing me to troubleshoot for hours and spend almost an hour talking to bell representatives...
NOT HAPPY. Bell - 5 in my books, lucky my contract is up in a few months and i can switch to telus where i will be able to get signal downtown...
Hey I have had my one plus one for a little under a year and after a 2 week road trip it has stopped being able to connect and detect the Wind home network. During this road trip I was on airplane mode for the full duration of the 2 weeks with the 05Q caulkin rom installed. Once I had reached my home town of ontario I had noticed that I could only connect to wind away on my opo. When scanning manually for the WIND home network it would appear with the simcard symbol beside it but when trying to connect it would state that it was unable to connect to the network. Although randomly throughout the day it would connect without warning until I rebooted my device where it would lose connection again. I then later updated my phone to the latest OTA which is cm12.1 hoping that the problem would be fixed but to no avail. At first it was the same issue where it would show the WIND network with the sim card symbol beside it but now I am not even able to see the WIND home network and can only able to see the Wind away network. I have tried changing my APNs and have tested my sim card on my sisters opo where it works perfectly fine. I have also done a factory reset and nothing has been able to fix the issue. I would like to fix this issue and anything would be of help.

Did you have any luck yet? Mine is still acting the same. I have been using my LG G2 for a while so I haven't really tried to solve the issue as I tried a lot previously as stated in my post.
Maybe you could post your solution here to help other members that may have the same problem ?

Have found found a solution yet? I have the same problem. Sim card works perfect on OnePlus X, Nexus 4, but not on OnePlus One. I get connected to Wind Away, and I've tried just about every fix including entering in everything manually.
did anyone figure out a solution? im having this problem right now
Wow... sounds like I wrote this thread - aside from minor details this is EXACTLY the problem I am having. My vacation was also two weeks and the randomly connect during daytime but loses connection once restarts sound all too familiar. After Wind store clerk did sim swap, new error msg appears and said "your sim card does not allow connection to this network", so the problem actually got worse. Eventually I had to switch carrier (to Koodo and it works).
No, I have not fixed it yet.
But I'm contemplating to try manual selection of radio band (in the *#*#4636#*#* menu), because mine is showing EURO BAND and USA BANDas choices. Tho haven't made up my mind yet because that might do much more damage than good, based on some Google research so far... frustrating.
Hello from Bulgaria.Some one have had a problem with 4g network.Samsung S7 when he was lte \ 3g \ 2g after 30-40 minutes , scope disappears and receives a missed call notification.The problem gone after restart the device and after 30-40 minutes is same situation.If a phone is an 3g\2g no problems.
Sorry for my bad english.
Same here
My cousin bought an S7 Edge, but it had the same problems as listed. She then proceeded to change the phone, yet the other S7 Edge had the same problem. What could be the solution to this problem, and what caused it?

Hi!
Go to settings and find your APN-settings. Remove IPv6 and save it. Then everything should work fine.
I'm having the same problem. I'm sitting beside my friend with his ip6s+ and he's not having trouble connecting with the lte. just saying that this might not be just a network problem.
I've read about multiple people, including me having this issue, for some the APN IPv4 switch seems to work, but not for everyone. So what is this? Is it related to the phone hardware or software? Or is it a network problem? And will it be fixed? As this is starting to irritate me a bit..
Many People in my country (indonesia) is having similar problem. The signal somehow stuck in 3g. Forcing it to use LTE only using the app "4G LTE Switch) makes the signal gone, emergency only mode. Only a reboot would bring 4g back.
However it only acts up when using one specific mobile provider (telkomsel). Switching to my second sim, also by the same provider, didnt help. But if I switched to another provider, the problem doesnt happen.
Widespread issue in Germany as well. It's carrier independent. Had to exchange one unit. The new S7 Edge I got works fine so far, but has a pink hue on the display. Samsung QA! -.-
Any solutions or updates?
Solved?!
Hi,
I had the same problem in bulgaria with telenor.
Yesterday i got an update on my s7 edge to XXU1APCH and it seems to solve it.

Downloaded bulgarian firmware,, XXU1APC8 is the only one available. Tried to check for update, nothing yet to xxu1apch...
Update:
Emailed Indonesian Samsung Support, they came up with a temporary solution:
go to phone, dial *#9900#
select debug level disable/low
change to mid
wait for phone to reboot.
2 hours past no signal lost yet
update: 3rd hour signal gone again
hi,
has anyone found a solution for the problem above?
in my case I have really slow internet (mobile data) on 2,3 or 4G, it's like it freezes when I try to open a page
when I connect to 4G it maybe works for a second and then nothing else, it's like 2G, very slow (wifi works normal)
can it be hardware problem? I already cleared cache and reset the phone, but it's still the same..
At me the phone can not change back to 2G from LTE, if 3G network is unavailable.
If I use LTE/3G/2G option and somewhere is not 3G network I can't receive or make voice calls.
Phone only works with 3G/2G option in network mode.
But in this case I only can use edge if somewhere only 2G and 4G networks are available.
If I use LTE network, the phone doesn't receive incoming calls.
I bought my samsung s7 gold one month ago in Lebanon (Middle East). I faced exactly the same problem, I couldn't receive any phone calls. Went to the store and they told me to switch from LTE/4G to 3G. Now my phone is always on 3G and working ok so far. But I can't put it on 4G !!!
get new simcard will fixed problem
Hi, is there a solution to this?
got info that there is a patching from samsung for this issue but since i am using custom rom, i cannot confirm this.
anyone has any update?
Same problem! I'm from Mexico and i just bought my pink s7 Edge on sunday, i've been going everyday to the carrier store and yesterday they finally gave me another one but im having the same issue! I can't take it anymore i don't know what should I do Maybe all the pink ones have the same problem? They have already changed my SIM Card, i have tried with another one and it still happens
This sounds very similar to the LTE problem on the Nexus 6P I wonder if it is actually the same problem.
When I'm engaged in an SMS conversation using the built-in Messenger app, my mobile network keeps dropping. When I try to send a text, it says that I need to insert a SIM card, and the connection bars show I have no connection. If I wait a few seconds, my network connection re-establishes and I can send texts. Interestingly, when it says I have no connection and I can't send texts, I can still receive them.
I've only noticed this happening when I'm texting.
Does this sound like a faulty SIM card, or could it be an issue with my phone? I'm with Bell in Canada on a 32 GB Pixel.
EDIT: I just noticed that this will sometimes happen if I've had my phone in my pocket for a while. I'll pull it out and the network connection will be dropped when the screen comes on, only to reconnect after a few seconds.
Are you in Toronto by any chance? On Telus? I've been having the same issue since late last week. Only happens in Toronto. On my commute to Burlington, everything is fine as soon as I get passed Etobicoke.
The issue for me is mostly on LTE+. That's causing the biggest headache. 3G and LTE seem to be fine. And again, only in Toronto. Outside the city everything (LTE+, LTE and 3G) all work fine.
The only workaround I have while Telus is looking in to it is to use 3G while I'm at home on the Danforth.

I'm in downtown Toronto on Bell. I haven't noticed this happen at home in the suburbs, although I use my phone a lot less when I'm not downtown.

So it sounds like the same issue. Telus and Bell share towers, so that makes sense. And you're having issues in the city but not in the 'burbs. The same issue I'm having.

Well, at least it's probably not a defect with the phone!
Just received an OTA update (NDE63V) that, supposedly, has an updated cell radio. I'll know in a few hours if this has any effect with my issue... As usual, phone is working fine right now in Hamilton.

When I run LTE Discovery, it says the LTE band is unknown.

Here's hoping they come out with a fix soon! I'm just glad it's not a defect and something that can be fixed.
I used the support feature on the google pixel phone today and a rep from google called me after requesting a callback. The chat feature was greyed out on my phone. When I brought up the issue of network randomly dropping throughout the day, the rep said this was the first time they've heard of the issue. After going over the issue of my network connection randomly dropping and reconnecting, sometimes accompanied with the triangle icon saying there is no sim card inserted in the phone, the rep called my service provider and left me with them to resolve the issue instead. They said it had to be something with the service provider and not the phone. I'm with Koodo Mobile which is a subsidiary of Telus. The Koodo rep did some testing and had me add a new APN to see if that would stabilize the connection but that didn't do anything. They said it's more likely an issue with the phone because it's connecting to the network but not sustaining the connection.
I've tried swapping out a new sim card hoping it was a faulty sim and that didn't fix it either. A factory reset also didn't do anything. I've confirm the sim and network wasn't an issue when I inserted my sim into my friend's iPhone 6s. There was no connection drop within the 15min sample size. I then used my friend's sim card on my google pixel, he's on Bell's network and the connection did drop within 10mins. We contacted a friend who works with Bell's networking service and he said this was the first time he's heard of this issue and there's been no report on his end of this. He doesn't work at the customer service level so he doesn't know if any pixel connection issues are being reported and brought up to a higher level. I should mention I'm in Toronto so there's no lack of cell towers around for a bad connection.
I'm going to see if I can borrow a Rogers sim card this week for some more testing to see if it's only dropping on the Bell/Telus network as others are reporting. Right now it's very frustrating, I don't know if it's a hardware issue or software issue.
I know it doesn't fix the problem but have you tried to drop to 3g until they fix the towers there? Should at least be less frustrating if it's specific to LTE.

That's only what a Google rep said. Hopefully it's not a defect that can be fixed via an update.

Hello,
I have for the past 1 and a half years an OnePlus 6 which since the start I have an issue related to 3/4G speed outside of my home country.
Now please don't start about turning on roaming in order to have internet. I have done that since I've got my phone.
I do have internet, however the speed is absolutely terrible. It is always on GPRS and goes with bytes per second. Texting goes sort of alright, loading sending images takes up to several minutes. Beforehand I had an iPhone and I used to have 3/4G with the same simcard.
I also have a work sim which on my work cell has a good range but on my OnePlus.. again I get hooked to GPRS and it goes on a terrible slow rate.
I have reinstalled my phone several times. Went from Android 9 to 10 and the issue is still there.
It also isn't country related because I have this issue in.. Germany France United Kingdom Italy Austria Hungary Poland. More countries I was not able to test yet sadly.
Does anyone has an idea what this might be? Is this a setting somewhere what is enabled on default? I know multiple OP6 users with the same provider as mine i compared some phone settings and they have a normal speed while I don't. So actually I don't know anymore what it could be.

Try forcing your phone to LTE Only
Dial *#*#4636#*#*
Go to phone information
Set preferred network type to LTE Only for 4G
or LTE/WCDMA for 4G/3G
In LTE Only mode, you may or may not be able to receive or make calls.
Get the following error

I don't see any error. It is working correctly as I can see. Your data is off. It's UMTS that is likely to be H+ network i.e. 3G.

Also Phone 0 is your sim 1 and Phone 1 is sim 2, FYI just in case.
I know everything looks fine. My connection says R
However I just don't have any internet with either sim ad soon as I go over the border.
If I put my sim in another person's phone it works. Their sim in mine nope.

Some networks doesn't provide data services while in roaming.
As you say it works in other phone. It seems your device is faulty.
You said you reinstalled Android 9 and 10. How did you do that?
Did you use MsmDownload Tool? Or just zip flashing? Or fastboot rom?
I would suggest to backup all data and completely wipe your phone using MsmDownload Tool.
If you've already done that then I'm afraid Network Module/Chip (usually referred as Modem) is faulty.
You will have to visit service center or repair shop to know exact fault.
