Help Pls!Can`t connect to network

Hi,
I recently purchased an AT&T Tilt (HTC Tytn II) and unlocked it so that I can use it with the Rogers Network. It worked perfectly for about three weeks then I took it to Orlando for a vacation. While I was there, I change the network setting to manual and connect it to AT&T Roger so that I can use it as a roaming phone. When I got back to Canada, I changed the network detection back to automatic and it connected to Rogers for about 10 seconds then it lost the connection. So for about 10 seconds, it worked but only lasted 10 seconds. I also notice that when it connects it shows E (Edge) as a data connection. After 10 seconds, it changed to 3G. As soon as it changed to 3G, it loses the connection.
I wonder if anyone has this problem. I don`t know if this is because I used it on an AT&T roaming network. I`m very puzzled and any help is greatly appreciated. Thx!

I am having the same problem. I travel to New York quite a bit. My phone would give me a message that it was unable to connect to the GPRS network. So I would go into the Comm manger and deselect the 3g. Then the phone would get a signal. I was not getting a 3g signal, but an edge signal. When I would come home to Ft.Lauderdale the phone would work fine no problems with the 3g till last week.
Soft reset I get the 3g signal 4 bars then it disappears I get no signal ! and then I get an Edge signal in about 5 seconds or so. Everything works but I am unable to get the 3g speed.
If I try to force the phone into a 3g signal by selecting WCDMA on the band I can get a 3g icon. The voice part works fine and displays utms but any time I try to use the data I get some sort of error message. Like dialed "proxy" no response or the remote party would not connect.
Do you think that we might have something corrupting the radio?

My old at&t rom doesn`t give me the option of selecting the band. Maybe I should flash it with HTC rom and at least get the voice part to work. I don`t know if the security scanning machine at the airport will harm the phone in anyway. They always ask us to take out the laptop and camera separately.

Phone calls drop data on 3G?

All, I am sure there is a thread on this somewhere, I just can't find it... please help.
I've got an AT&T Tilt with stock ROM, no bloatware. The problem is that when a phone call comes in (or I dial out), it seems to drop or interrupt the data connection even on 3G. Very annoying.
On my 8525 with WM6 ROM, this never happened. I could be connected to the internet (typically connecting my laptop via Internet Sharing on the 8525), and be talking on the phone at the same time -- the data connection was never interrupted. Of course if I was on an EDGE or GPRS network, it would -- but that's to be expected since GPRS/EDGE use the same radio as GSM. On the 8925, as I stated above, a phone call interrupts data even on 3G!
Has anyone seen this? How do I fix it? Thanks.

Yep overhere also... testing all radio roms but all the same... so far no fix found... we have to live with it...
The kaizer is dead... long live the Kaizer...
... to many problems

I'm in Edge country right now, but will be in 3g in a few minutes as I'm getting ready to roll out to LA, I'll email you from the car to test if the 3g and phone call can co-exist.

I think it has to do something with AT&T's cell towers. I also experienced the same issue that when calls came in my data connection would be cancelled. However one day, out of the blue, the 3G icon was suddenly replaced by an H icon. And it is there all the time! Now I can call and download data at the same time.

Thanks... that's bizzare. H means it's using the HSDPA protocol for 3G, U means it's UMTS, I think now the 3G icon shows up instead of U. (I hope I got my acronyms right). But that shouldn't matter! My phone will go between 3G and H, I think based on the capabilities of the towers. There is no telling what will show up in a given spot.
The mystery remains... Come on, all experts out there, share your wisdom. Could this have anything to do with disconnection settings or TCP settings (done via KaiserTweak)?

I think I just found the answer. Went to KaiserTweak, and selected the Data/Disconnect After setting, which I had set to 1 minute. In the description for that setting, It says "warning.." but you can't see the warning unless you go to landscape mode, which is why I never noticed it before. The warning says that with this setting, 3G Simultaneous Voice and Data will no longer work.
Disconect disabled, and a quick test showed that the problem is solved.

N1 - No 3G or HSPA!

Hi-
I have a Nexus One and I am having a problem where if I am in a location where there is HSPA available, then my phone loses 3G and HSPA connection. My phone has a 3G icon, but in the testing menu it shows that is keeps flipping back and forth between HSDPA and UMTS. Also the up arrow continuously flashes, but I don't receive any data back.
When I leave the area with HSPA service and switch to another tower which has regular 3G then my phone works fine. I figure the issue has to do with my phone missing something or having a corrupted file that is not letting it connect to HSPA service.
My phone had no problem connecting to HSPA earlier this week but all of a sudden I am having problems.
Anyone have any ideas?

I'm on vacation in Fort Collins, CO and have been having similar problems with 3G
only showing the up arrown and never downloading. I got sick of it and switched to EDGE for the time being. My wife has an N1 also and it is doing the same thing, so it looks like it's not the phone. I switched over to CM6 which has the 3G and H indicators and it will only download data with the H never the
3G indicator.

I also have the same problem. When I am on HSDPA my up arrow gets "stuck" and I lose all data connection. Here is a link with others having the same issue. http://forum.androidspin.com/showthread.php?t=2720&page=2

Have a look at your apn settings in menu I had that prob and switched a few this around and got it kinda working
Sent from my Nexus One

my build.prop file was apparently missing the necessary entries in it. I flashed CM6 and now it works again, although my phone now thinks I am in Phoenix instead of Dallas.

Phone was working fine then all of a sudden doesn't work. No change in the settings. Has to be network related.
Starting at around 1AM EST last night 7/11 and running until this moment I have been going back and forth between Service, No Service 3G no 3G, able to place a call and unable to place a call.
My bet is there working on the network with this new HSPA+ roll out. The problem seems to be in markets that are expecting the roll out. I live in Jacksonville Fl. Up until last night I had flawless 3G and Data. It was terribly fast but I had it.
Now over the last 12 hours or so 3g Voice and data has been intermittent with no settings made to the phone.

[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

3g not working if radios set to 3g only?

I noticed if I go to the mobile networking settings and have it it on lte/3g if I leave a 4g area, 3g works ok. If I put the toggle specifically on 3g it shows I have 3g, but anytime I tried to search google or access a data connection the signal goes away and gives me the signal with an exclamation point. I tried finding info on this, but didn't see anything when I searched. Anyone else have this issue? I am on Sprint with the 64gb white device. Thanks

I leave mine on 3g due to the lame multiple text issue. It has no problem staying on 3g. Perhaps try updating your PRL/profile and see if that helps.

I don't have 3g either if I set it to 3g only. I don't leave lte service too often to test whether 3g works when it switches on its own. I may have to make a trip to the mountains to test it. I do know that my old Note 2 would loose lte after flashing tons over and over and I would have to flash back to 100% stock the factory reset from the settings app to fix it. I may try this with my Nexus, about time for a wipe anyway.

Factory reset does not fix it. Just noticed that I don't even get 3g when it is set on LTE. I'm gonna go talk to my cellular provider about it.

I don't know why it wouldn't work. You did update profile and PRL also right? Here's some shots of mine and it's working fine.

I have a bad Sim.....I also don't have a phone number as well..... I swiped with an old card I had and my number appeared, I guess I'll be visiting the store tomorrow to get a new one. Maybe it'll fix my 3g. Its also not wanting to let me pick 3g as an option now, just stays on LTE.

KB112 - Are you on sprint also? I updated prl/profile and no luck still. 3g still works if I am on lte and go into a 3g zone, but if I toggle it to 3g only I get no data. Wondering if its a sprint thing or a lollipop bug on Sprint, or a bad sim, missing feature activation.
Bluemgt06 - did a new sim fix it for you?

Sorry, didn't see this earlier. But yes, I am on Sprint. My 3G would work fine if I set to 3G only. Not sure why yours has issues with this?

Oddly I tried it today and it started working. I think it could have been some kind of issue with the tower/upgrades or a bug that a reset may fix on occasion perhaps.
