I have had my xperia T for about 6 months or so and since day 1 on both stock .140 and .141 roms my phone would display having full signal or at least a couple of bars, but when i go to send a text or ring it would say no service for a call and unable to send for a message dispite having full signal, a quick reboot and everything was working again fine.
My phone would do this maybe once a week, once or twice it did it a few days in a row then other times it would go weeks without doing it.
I got onto t mobile and they reset some settings, didnt do it for a while but eventually it did it again, I go tmobile to do me a new sim card and the problem went a way for a while, but eventaully started again.
Its quite uncomon it does it really, but then it does it is very annoying, just wondered if anyone else had suffered the problem and found a solution?
Thank You
No one else has ever had no service despite their signal showing bars?
I have done a bit of a test with this and noticed that if I just use GSM only I have no issue, I think the problem is something to do with the way I turn mobile data on and off.
As I am in a position to use Wi-Fi almost all the time I opted for a contract with only minimal mobile data as I knew I wouldn't need much of it. So I only turn mobile data on now and again to search for something if I am away from a Wi-Fi connection. I can't say exactly how the fault works, but I think if I connect to 3g, do what I need to do, then turn off mobile data, the next time I go somewhere and loose signal my phone fails to re join the t mobile network. It continue to display the correct about of bars, but if I pull down the notification bar I can see the phone actually has no service.
It is not until I go to make a call or send a text do I notice this really, but no one can get through to me either.
I'm 99% sure if I use mobile data on GSM I don't have the same issue, it seems to just be an issue with allowing the phone to switch between WCDMA and GSM and using mobile data.
After a bit of a Google search it appears Xperia Z users seem to suffer a similar problem judging by other forums, but no one has come up with any solution.
I think I have had this issue on every stock firmware I have used.
Any ideas anyone? Thanks

I just took a trip for the weekend and much of the area i travelled thru didnt have cell service. However I found that when my phone was in a cell service area it wasnt making calls. here is the scenario...
driving down the highway, my cell isnt finding a signal, it sets itself to the airplane setting & thus calls cant be made, my wife's curve has a signal & she's on the phone, so i turn the phone back on & try to make a call...it ends my calls before it rings. i try to wait to see if its a timing issue, 10 minutes lapses, wife still on phone, i try to make a call, no go.
i had to cut my phone off & cut it back on to get the phone to work?? it recognized a signal as i had 1 bar of signal reception on the tilt and my wife's curve had 2 bars. but it'd never start a call. i'd see that it said calling, 3-5 secs later it said call ended...
anyone have any idea as to why this would happen or why i'd be required to restart everytime i leave a cell service area & reenter one? any fixes? i searched for my title & found no results...
Are you on 3G or GSM when it fails? If it's on 3G, you could have that problem, try to switch to GSM only and see if it's better.

well as far as i know we're not getting 3g until may...but i do drive towards a 3g network, so it may have been switching over to 3g prior to driving into the back country?

what rom are you on? the 162 htc/att rom? bcuz i know now i am having a problem i wasnt before. because there is a building downtown that doesnt get cell service in it, and i frequent that building. i never had the issue on my original tilt on the 158 (i believe) rom, but this rma came w/ 162 rom & now im having the issue in that bldg too. which goes to further prove its not the 3g network theory. its just a matter of losing signal & then getting signal back where i am experiencing the issue.
thanks for any help.

Today was day one with the new tilt and it didn't have the problem. However, my old one wasn't consistent one way or the other, either, so I'll have to give the new one some time.
(work for at&t) New phone will not fix this problem, nothin wrong w/ phone. U need to go to a local corp store and change the SIM and get someone who knows what they r doing so they put all of the SIM updates while plugged into the comp. OTA updates will never work w/o these initial updates.
I have an issue where i'm connected to the net (GPRS/hdspa) and occasionally i will lose the connection whislt the connection is still active..
No internet functions will work even when i reconnect
I have to then restart the phone to be able to use the internet again
Not the same issue but something similar
Same problem here. It is not possible to establish a 3G connection. If I set the BAND in the telephone Settings to GSM the connection is stable. If try to establish a 3g connection all further connection trys will fail.
I already changed my Kaiser, it did not help.
Update:
T-mobile will sent me a new sim card. Hope this will help...
Hi all,
I have bought a Htc One M7 handset recently and I have noticed time to time there are No Signals (Limited Service) on it. When I switch off/ switch on or if I turn on the Airplane mode and turn off again, the signals will restore. This is happening around 2 times per day and really annoying. Need to know whether this is a known issue for the model.. I still didn't change the SIM and check. Please help!!!!!
Thanks alot!

I have the same thing
To add some detail for diagnostics see below:
- I travel into London every day and sometimes when signal drops in the tunnels it will never pick back up again after leaving them whereas my old One X did not have this on the same journeys.
- It even dropped out mid call and came up with the sim card icon at the notification bar as if no card inserted (but no selectable notification) first time its happened to this extent.
- Do you have a 4G SIM/connection or are you on 3G like myself? I'm thinking perhaps its something to do with trying to pick up 4G instead and completely disregarding the 3G connection that is available.
- I have also noticed that ever since getting the handset its never had as good signal as my One X which was pretty much always full signal in my normal areas (home, work etc) This may just be the way the handset gauges the signal not the signal itself but something to note anyway.
I'm having the same issue here in the US. It's prolly my only complaint with my phone.

I'm also having this issue but more sever with an all-day no signal. After reboot, I gain signal and I can't make and receive calls.
Try to turn 4G off.

How does one do that? Having the same problem, both wifi AND mobile network drop off. Wifi comes back on its own after a few seconds, the mobile data connection often comes back (obviously if not on wifi away from home), but the mobile network stays as no signal and doesn't come back, unless I reboot or cycle aeroplane mode. I know there's some problems with touching antenna, but this is happening a lot in the car, when the phone is powered and sitting in a cradle.

To turn off 4G you go to Settings -> Mobile data -> Network mode and then select "3G / 2G"
don't know if it'll help though, but trying is worthwhile

Thanks. The problems seems to have gone with that change. Perhaps it is some system thing kicking me off the network because I don't have 4G on my contract and my phone was trying to get it.
Now, if you can just tell me why my lovely 3-4 bar indoors signal on EE has dropped to 0-1 outdoors (as they deny there is a problem)

Are you sure it's not just cosmetic? Try going into Settings->About->Network and see if the signal (dBm) is dropping.

I have it constantly on att - I have to turn on airplane mode and turn it back off to get my network back, I have tried different roms and updates and still the issue is across all roms.
Maybe try this: in your dialer type *#*#4636#*#*. Once the menu is opened, select Phone information, then scroll down to Set preffered network type and choose one of the options (im from Serbia, europe, and I usualy go with GSM auto (PRL)).
Issue with 3g only
Whenever I keep it on 3G, it drops signals for 2 to 7 seconds at random intervals. People often complain that when they call, they get a message that my phone is switched off.. I am probably gonna try another ROM and SIM to see if that helps before dumping this phone forever.
how to solve limited service or loosing service on htc one m7
Hello
it seems to be a hardware fault where the radio is not staying on higher band
it seems to be having issues on 2100 and all umts and hspda or lte networks
however switching back to 2 g can resolve this issue and phone ( hope so) will never lose signals or drop then again
i tried this and for me this works fine so far over 12 hours now no issue
give it a try and see this should work
setting>data>network>2g only
by this you wont have option to use fast internet though but at least you can phone can be used for voice calls messaging etc and also wifi too
I was on stock lolli pop and tried to flash cm12.1 but does not help sort the limited service issue
enjoy and leave your feedback
Edit:
some people cant find 2g in settins>mobile network>preferred network type> lte or 3g only, the solution is go to *#*#4636#*#* phone info>set preferred network type>gsm only( this will put your device into 2g mode)
hope this work
Don't know if anyone else has had this issue in this forum, but I have found several others with same issue in other locations. No one has come up with answer and HTC has been no help.
If I lose my signal, due to location or if I drop off of wi/fi and go to cellular data, it seems that the phone loses the ability to make or receive calls or texts. For example, if I leave a strong signal area and drop to edge service or none, and then return to a good signal location, the phone shows full bars and 4G but if you try to make a call it will not connect or if someone calls in they just go to voice mail. I have to reboot the phone and all is good. This seems to happen several times a day, never any issues with iphone 4s or Galaxy S3.
Here is what I have done and then after the fact HTC sent me an email telling me to do same thing.
1. Got new sim card.....HTC is convinced that the sim from my iphone was not good.
2. Exchanged for new phone.
3. Ran phone without syncing to my google account or any downloads.
Still same issue with losing connection. Most of the time I don't realize it until someone says, hey I have been trying to call you. I reboot phone and, wow, several missed calls and bunches of texts.
Let's see what they have to offer after the complaint.
Thanks

Hey, similar problem here
The difference is that I only loose mobile internet when disconnecting from wifi in AOSP roms (and GE), on sense roms it seems fine.
I have however noticed a pattern, it might help some one figure it out, but it might help you too.
I only lose Internet when disconnecting from wifi If 4G Is on, if I force my phone to not use 4G, then I don't loose network.
Also, if I do loose network, a reboot isn't required, you can simply Turn airplane mode on and off, that has always worked for me.
Ps: to force the phone off 4G I do the following :
1: open dialer
2: type : *#*#4636#*#*
3: go in "phone information"
4: under "Set preferred network type" set it to "wcdma preferred"
The reason I prefer this method is that it's always the same no matter the rom.
Pps: my baseband is 4A.17.3250.17, if that matters for any reason.

Same problem here....
Not solved...try everything...but no luck....
I get it too seems like the phones radio doesn't switch frequencies as smooth as other phones.
I've seen a number of threads where people post about their device dropping network data connectivity, and needing a reboot to solve it.
My issue is a bit different. Occasionally (I've noticed it 3-4 times today) when I go to send a text (SMS) or to use a data enabled service like Hangouts, that my phone shows no bars at all.. not even just no data, but the bars are grey and there's a red x. I wait about 15 seconds and it reconnects, then another 10 seconds later, the data is live again.
Phone is a private sale and under 1 month old, and all the Stamina functions are off.. I do see that the "Queue background Data" is turned on, but I don't think this should effect, no?
Not sure what digits I should be looking at to know if this might be a hardware vs software issue.. build is listed as .93
Im no stranger to unlocking and flashing, but I've kept this stock cuz it's tight and I adore the battery life.
Suggestions?

Been about a month since I posted, and I'm still experiencing this issue. I often thumb my phone on and it's not connected. I don't really mind waiting for the 30 seconds or so that it takes to jump back on the network, but it often means I miss calls, and since it's my business phone, it kinda bums me out to suddenly get a VM notification of a missed call even though it never rang.
Is there some sort of utility that I can use to monitor the network activity to see how frequently it drops, and for how long? I've looked into ones on Play but they don't seem to have a history, just something that shows what data up and down is currently being reported.
Sadly the only Sony store in my city (and I think the country - Canada) has recently closed for good, so I'm not sure how to go about warranty repairs...

I don't have a solution, but I can tell you that you're not alone. I've been experienced the same thing on my Z3C. I sometimes wonder if it has anything to do with the fact that the MVNO I use doesn't support 4G LTE.

Interesting.. Your issue isn't just data, but a complete network disconnection? Im with Fido which is an MVNO under Rogers, but I thought they supported LTE. The issue also persists even on wifi

Yes, it seems to be a complete loss of the mobile connection. When I wake the phone I see gray bars and a red X on the signal strength indicator. Within seconds the phone re-acquires and the indicator goes to 2 or 3 bars. I have also seen it happen with wifi active. The frustrating part is that it doesn't seem to do it often enough to troubleshoot. I'll notice the problem maybe a couple of times a month and there's nothing obviously different about my usage patterns in those instances.
Mine does it at least a dozen times a day. I can only assume this as I frequently miss calls and at least 3-4 times a day I see it happen. =(
Same Problem
Randomly I have no connection at all but after a few seconds everything wents back to normal. Did not have this problem with T-mobile in Germany but with with O2 I have. With T-mobile I had LTE but with O2 I don't, so I guess that's the reason.
Interesting... I've disabled LTE and now have it on 3g/GSM. We'll see how it works moving forward, and I'll post again in a week. Stay tuned.
Service Providers
In the mobile network settings one can change the service provider manually. With LTE enabled my provider has three entries: LTE, 3G and 2G. Connecting two LTE fails, because my provider blocked it in my plan. Having LTE enabled, it often tries to connect to LTE I assume. I switched off LTE and set the provider manually to 3G. Maybe that helps. We'll see.

Hi, so my problem is that i keep losing mobile signal (3g and LTE). I put the SIMcard to another phone and everything works fine.
Did a factory reset and still nothing, i even installed Sony Stock Jelly Bean ROM and again nothing. When it's set in 2G it works ok.
The other thing is that i can't tell when the signal is lost because it actually shows that there is signal but when i want to call someone or use internet i can't. Could someone help please

Note: This reply won't be helpful
You might have an issue that is similar to mine. My XSP also shows signal, however, the difference of your issue with mine is that, I cannot receive any SMS, or calls. If I attempt to call someone, it somehow "triggers" network polling and then the signal resets to a correct one. After then I am able to receive calls.
However it is persistent, later in time it will "freeze" again.
I highly suspected that it was my XSP. Fortunately upon some closer look, the true culprit would be the radio tower (reception) at my home. At my university, the network works extremely fine. And if i return to my home, the same issue reappears.
I guess you should try going to somewhere else that is quite far from your home, and check if the issue persists.
If you are however having such issue constantly everywhere, it might also be plausible that a certain bands are out of service at your area
Well about the area service, my friends SG S4 is with the same mobile operator as i am and has no problems with the signal or mobile data. Any help on what to do ?
