Okay sometimes my N1 will lose all service and in the Notification Bar it will display "Emergency Calls Only". This doesn't go away and I don't get service until i restart my phone. I don't understand why it does this. I am running CyanogenMod 5.05 and my carrier is Cincinnati Bell. What can I do to fix this?
I do see this sometimes (albeit rarely) in areas where T-Mobile has low coverage (I guess that means it would roam to AT&T to make a 911 call if needed).
But as soon as I get into an area with good coverage it's solved. I don't have a need to restart the phone.
What radio are you using? Have you tried also just turning off the radio and turning it back on, or for example toggling 2G only? That might trigger the radio to re-connect.
The radio I am using is EPE54B.
Your explanation as to why this happens sounds reasonable. The location that I normally see this happen does not have the best coverage.
Next time it happens, I will try toggling 2g only.
Is there another way to turn the radio off and on without restarting?
Airplane mode. But be warned, toggling 2G or turning Airplane mode on/off usually doesn't work with this issue. A reboot is generally faster.
Also FYI, if you aren't aware, you can soft reboot by holding down Trackball+Power+Vol Down. Click all three simultaneously and the phone will reboot within a couple seconds.

Running CM6-RC1, and in areas with weak signal, my phone will say "emergency calls only" and have full bar strength and no data connection. Does this mean its connecting to a different provider's cell tower for purely emergency call purposes and showing that signal strength?
I would actually like to know this as well. I noticed this earlier today hadn't happened before. That is what I think it is because Telus does have better reception in this area.
That's exactly it. When you lose signal with your regular network the phone will find the next best, but unless you have a roaming agreement all you can make are Emergency Calls.
Slightly annoying when you don't have the network name visable for most of the time. Would rather have an alt icon.
I have this same issue too. However, I need to reboot my device in order for it to work normally again, it does not appear to automatically re-connect to my network, even though it has signal, unless i restart the device.
Title pretty much sums it up. Whenever my phone goes to 3g it won't go back to 4g til I reboot or until put it in airplane mode and back.
And as a side note, whenever I put it in airplane mode and change it back my phone reboots itself..
That's strange. Are you rooted? Do you have any apps that tinker with data settings?
Try a data wipe
Not rooted, the only app I have that I think may do something is zdbox but I doubt it does
I would uninstall it first and see what may be going on. Are you still unable to connect to 4g without rebooting when on 3g?
Is possible the 4g network is having issues in your area. What city? I will check the alerts at work and see if there are any issues in your area

It only does it like once a week. Good ole Dayton ohio
Also something I just realized, every time i turn on my wifi my phone goes to 3g
Ok here's the deal. Upgraded to ICS 232 and all went pretty much flawless other than motoprint no longer works. All was good and I was in happy land. However with ICS was stuck in 4g mode all the time and was sucking my battery like a hungry vampire. So I went into phone info and changed to CDMA auto PRL . Locked me in 3g only. Was back in happy land, battery life good again. Well I wanted to use my 4g so I went in to turn it on and it kills all data. No 4g, no 3g not even evdo. When I reboot it always resets back to CDMA auto PRL only.
Any ideas short of factory reset?

Turn off phone, remove SIM, reboot without SIM. After it's on, turn it off again, re-insert SIM and restart it. Try toggling 4G with *#*#4636#*#*
This sometimes works, as does toggling airplane mode

Same problem for me. I have tried toggling airplane mode, tried toggling wifi, rebooting, simply cannot get the phone out of cdma only (prl) mode.if anyone has experience in fixing this, it would be greatly appreciated! I even went though VZW's level 3 tech support and told then I have Ics on my bionic (which didn't void my warranty?) But they were at a loss...
SOLVED

you cannot switch back to 4g (LTE/CDMA/EvDo) if you have "Data roaming" enabled. Uncheck the data roaming box and try it again. Worked for me. :good:
Had this happen to me when I tried to enable Juice Defender's AOSP helper on the official ICS (though I had to update manually using HouseofBionic's method). It dropped me to 3G only, and the "preferred network" setting is grayed out, but showing LTE/CDMA. Clearly, the setting was inaccessible.
I uninstalled AOSP Helper, then disabled JuiceDefender.
Then I went into the Hidden Menu (that 4636 thing) and it says CDMA Auto (PRL). I tried to change it to CDMA/LTE/EVDO , then reboot, but it's still 3G. Went back into Hidden menu, it's back to CDMA Auto (PRL).
Went back in, change it again to CDMA/LTE/EVDO, but this time there's a "refresh" button below that, to update the IMSC I think. I hit that.
Reboot phone, now I have no 3G
Went to settings / data usage to toggle data, nothing.
Went to airplane mode, out, and voila, 4G/LTE.
Not sure which one of those actually forced the update, but it worked, so if someone else had the same problem, try that.
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
For the last two days I haven't been able to get a signal (No bars, just a triangle). I've updated, rebooted, and toggled airplane mode with no luck. I did get a brief 2g signal when changing between 3g and 2g but it only lasted a few seconds, not even enough to try and see if I could make a call
