restart after loss in service?

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?

i checked & the phone is actually set to gsm only already...so this cant be the issue. any other thoughts?

Wish I had an answer, but my phone does the same thing. I must reset the phone to get a signal

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...

Kaiser : When 3G icon appears ATT Service is lost...

I am on the old $39.99 ATT plan the one that does not have 3G and my with an old “blue” SIM card. I have been using Sony S710a for the past two years which in fact worked fine. A week ago I have obtained ATT Tilt (HTC 8925), unlocked it so that it would read my card and started using it.
Here is the problem that I can’t solve>
Sometimes my phone loses service, completely, and I cannot reconnect to ATT Service. I have tried to find a pattern but so far I am clueless of what might be causing it.
According to my observation:
1. It has been happening in certain neighborhoods.
2. When I do find service and connect to it shows E and then switches to 3G
3. When my phone starts to show 3G it loses connection.
This phenomenon happens only from time to time. Other times I have 3G icon and everythign is fine. I have tried T-mobile card in it and there is no problem. It connects to T-mobile service and has all bars. Thereafter I have put my card into an unlocked Nokia 6300 and my ATT connection works fine. The only thing I can blame is 3G.
Please if anyone knows what this, why its happening and how I can avoid this issue let me know. Thank you.

it looks like I have got a solution...
Im not sure yet, but so far I have installed an application that supposed to keep me away from [3G]. The application that I have installed is Bandswitch. So far it only shows [E] . I have to travel to those areas where I had no service to be sure that this program works. Ill keep you updated on this issue.

go get a new sim card. ATT and Cingular towers were different so some older sim cards have trouble connecting to some towers. its only something like 15 bucks.
when i went to the ATT storeto get my tilt, even though i already had a 64k sim they still upgraded the sim (for free seince i was about to pay 400 bucks).

Its your sim card
The old sim cards don't have enough memory. Get a new one with the 3g logo on it. You should probably upgrade your service too. Or you'll get a big surprise when your bill comes.

I have the same problem here in germany with the O2 3G Network... My phone has a GPRS Connection and when the 3G Icon appears there is a total loss of connection for like 10 seconds and its back to GPRS again... End of the story (like i assumed and wrote to O2 ;P) my SIM Card is too old, new one on the way Should work for you as well, like all the other posters before me claimed
Edit: Oh and it didn't cost me one buck, all inclusive service because i didn't lose or broke my SIM Card. When it is too old to be able to allow you to use your full contract properties, i guess they pretty much have to send you a new new SIM card for free. At least here it works this way

Thank you...
The problem is that I dont have a contract and the only way for them to upgrade my sim to 3G is when i sign up. Curently I have 1000 min, nights and weekends from 7pm, free mobile to mobile, free long distance and free incoming SMS. Its highly unlikely that any one of you would give that up and pay more money for less minutes and less services. Right? Thank you. at this point i think im fine with what I have got, in addition to not needing 3G at all. by the way, i think that this program Bandswitch is doing a good job keeping me of 3G. Thank you.

I never had to 'upgrade' my sim to 3G, nor sign a new contract. I just took my old GSM SE phone in to ask about service, and they asked if I would like a sim swap to the latest.. Sure, done.
Now works fine with the Kaiser, and never did any form of 3G 'upgrade'.

Were you part of the old ATT Blue network? Cingular actually started giving out 3g cards in early 2006 in my area. I got one with my 8125 where they FIRST came out. So it's possible if you've gotten a phone since then and now that your card is already 3g...

You're right, I think it may be important to be on the 'orange network' because 3G never existed for the old at&t wireless 'blue'.
I was always part Cingular, and did go through the free-sim upgrade, but got another one when I just walked in after that.

Well I'm in malaysia, Using Maxis 3G network. I also having problem same symptoms like you guys. What do i realize sometime it give my device freeze for sometime. But the freeze just like for few second. And what do i realize when 3G appear our phone signal become weak. From full bar drop to 2 or 1 bar.
Did u guys having this issue too?
My simcard is 128k if im not mistake.

See this: http://forum.xda-developers.com/showthread.php?t=335074
Most likely the same problem. RMA ahead.

Try this on your phone settings (dialer --> menu --> options) on the network tab is network selection set to automatic? i was experimenting with my phone to see if i could get a better signal and set it to manual and choose my network but when im no a 3G connection its called 3G T-mobile and when not its just called T-mobile and on the manual list its just called T-Mobile so each time i got a 3G connection it would lose signal completely and start searching for i think T-mobile not 3G T-mobile the moment i set it back to Auto and soft-reset it worked fine again.

my phone did this at first, and all i had to do was get a new SIM. they didn't charge me a dime for it at the att store, but if they ask just tell them your phone won't connect and that it's a problem with your SIM

I have the same problem and have a new phone on the way. I already have a 3G sim card.
When you call, they'll probably make you hard reset your phone. Just a heads up.

3g Issue - UNUSUAL

Basically, my N1 when on stock worked perfectly with 3g, yes sometimes it was a bit patchy but it worked. I am using my old blackberry sim (UK), with the internet converted from bberry internet to normal.
Everything was going fine until I put my brother's orange sim in my phone (UK) [he also has a stock nexus, although at the time i was on 5.0.0.3 CM] to see if it was just his phone which had a 3g issue. I never managed to pick up 3g while his sim was in my phone, even though 2 blackberry bolds sitting next to it with orange sims in had perfect 3g.
ANYWAY THATS NOT THE ISSUE.
After replacing my sim in my phone, Ive never since had 3g, ever, even on routes I know the signal is immense.
What I want to know is 1) what would swapping sims have done to the phone, 2) what I can do to possibly reverse it so I can enjoy my 3g again
CM .6
Desire CAM + OC/UV
Cheers

I haven't had this same problem but if I were you I would go to your carrier and get a replacement SIM card. The last time I had a weird issue like this I replaced my SIM and all of a sudden I got pure 3G signals everywhere where I hadn't before. If you get the new SIM and it still doesn't work, try wiping and install a completely different ROM (perferably stock) and see what happens.
Hope this helps!

But before I put my brothers sim in my phone, my sim worked perfectly fine, so I was thinking it was more likely to be phone than my sim?

Anyone have any ideas?

his sim seems to have disabled 3g somehow in your phone, though I've never heard me that before. have you gone into the info menu and seen if your 3g is still enabled? *#*#4636#*#* on your dialpad.

WHOOPs, yeah I had it off [while we were testing etc] and sort of forgot :/ Which setting is it meant to be on, GSM/CDMA auto?

you want it to be on WCDMA Preferred.

I've set it correctly now, and am getting 'H'. I didn't actually realise that it is a type of 3g network, however I am SURE It used to say '3g'. UK O2 if it makes a difference.

well H stands for HSDPA which is what some ROMs show. so have you flashed to a different custom ROM? either way you are getting correct high speed network, so no worries. my nexus only says 3G even when i'm on HSDPA.

[Q] HTC One signal drops

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

Frequent Random Network Drops

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?

check in settings in network and set your network to the one you use , like gm/wcdma /lte , maybe your phone is strugling to find 3g or 4g , try it , who knows it might solve the issue , ty

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.

Interesting.. I have LTE as part of my network and plan... But once I made changes to the settings as I indicated, I no longer receive the network drops I originally experienced.. I might just be missing the alerts, but it seems fixed... #crossedfingers
