Lost of Signal Issue help

My MDA lost its signal and it can't seem to reacquire it. Is there anything I need to do? I had this problem before and it sometimes comeback after a soft reset but I have been doing that for the last 15 minutes and it is still out of service. Any suggestion would be appreciated.

Do other phones on the same service work? One day i thought my phone was broken too. I kept losing signal. then i went to work and it worked fine. Turned out there was a problem with the tower by my house.

No it is not the tower. I experienced this problem a few times already. It would lose signal and then it would take it a long time for it to reacquire/register with Tmobile.
Sometimes it takes a 1 minute and sometimes it seems to never (i waited for 15 minutes and then I do a soft reset) come back.

I'm not sure if this has happened to TMo customers, but I know Cingular customers have experienced fried SIM cards. I've personally experienced this and had to get a new one from a Cingular store. Thankfully it was free. I experienced the same symptoms. My phone would never acquire signal, even after a hard reset. If you can, try your SIM in another phone, or better yet, try a different SIM in your MDA. Good luck.

Help: Need help figuring if this is a phone issue or carrier issue...

Ok, I've had an 8525 unlocked for about 3 months now... Unlocked and used on t-mobile's network...
Until recently, I've had 0 issues with my phone from what I can remember(now running PDAs v20 windows 6.1 rom)
My problem is, during the day, in my room I recieve any and every phone call that comes in, calls never drop or hang up, BUT the call seems to cut out for about 5-15 seconds and then cut back in.. even though it says I have 4 bars.. in my kitchen with 4 bars, I get all my phone calls, but can't hear people (nor can they hear me at all)... I get emails, and browse the web fine.. but can't use google maps app (can't find my location until I leave lol)
I don't know what's up... at night, when I'm in my room, my phone works fine with no cutting out and in during calls, but during the day, that's when it wants to act all crazy... other t-mobile phones work perfectly fine in my room... my old sidekick also worked fine..
when I'm anywhere else in my city, my phone works fine (even with 2 bars)
I know nothing about how cell phones work when communicating with cell towers so any help someone can give me will be very helpful as I do not want to catch an aneurism calling T-Mobile themselves for help (though I doubt they'll help me since I'm using an unlocked ATT phone on their service lol)
Also... sometimes txt messages come and give me a time like it's in another time-zone... usually this happens when I'm out of state roaming on a different network (Immix in central PA for the most part) but now it seems to be popping up even while I'm home in NY...
any ideas?

seems like some kind of interference near your home...could be a carrier tower or even your TV? You could check with tmob if others in the hood are having day issues...
not sure what radio version u have, but u could try flashing a different one...

I've tried numerous radio's but having the same issues... it's some kind of interference in my house I guess.. I just can't figure out what it is... I called up t-mobile and was embarassed when he said "oh u have an ATT phone" lol he told me to switch sim cards with someone else on t-mobile in my home to see what happened... but.. no progress... I unplugged my wifi router to see if that would help but it didn't
I just find it completely odd that my service craps out on me in my room ONLY during the day... and it never did this when I first got the phone.. I'm completely lost... good news is, it only happens in my house...

Could be someone close by has just invested in a piece of equipment that is causing interference.. Might not be just in your place...

yeah, another thing that MIGHT be causing the interference is that they have been doing a lot of road work in my area... that could also be why it happens during the day but not at night... my kitchen is a different story, but different radio's have gave me different reception... with some radio's... it fades out completely and with others it'll fade out for maybe a second or 2
or it could be my neighbor who recently had a stroke, I guess there might be some machines in there.. who knows
I tried the latest radio and it yielded the best results in my kitchen so far but man oh man does it burn battery when I'm on the phone

I'm having the same problem...well as far as the text msgs go so i called tmobile last night and they took me off the network and placed me back on and since then I havent had any problems

Update: I put my GF's att sim card in my phone and went to all my "dead spots"... even when the signal bars were down to almost 0, the quality of the call was still clear and it wouldn't fade in and out during a call... Does anyone know if there's anything T-Mobile can do? Because I tried my moms sim card in my phone (t-mobile) and gave me the same crappy results (calls fading in and out at full 4 bar signal)

Data Issues??

Occasionally I get no data connection & I have to restart the phone, does any body else have that issue?

I have that issue as well, idk why it happens but I'll add it to the list of problems for when I call to get a replacement.

That just happened to me today also. It switched from "H" to "E", then when I opened USA Today it FC-ed and the icon turned into a generic Android one like the app was on the SD card and unavailable (even though it's installed to phone) and then 5 more background apps that I didn't even know were running FC-ed (Amazon MP3, Finance, QuickOffice, something and then Facebook three times?) and the phone locked up. I was able to power off then back on, but data never came back even after waiting about 10 minutes until I powered off and on again. Quite odd.

I get the same issue where am connected to wifi and as soon as i walk away from it it doesnt connect back to the data network. I got a replacement phone coming so hopefully i dont have the same issue. Another thing is the random reboot and i get black screen a lot especially after rebooting

I've had the issue, but each time it appears to be related to JuiceDefender not properly enabling the radio. If I shut JuiceDefender off, the connection comes back, although sometimes its just easier to airplane mode it and be done with it.

I called T-Mo about it, they said call about a week after the inital release date and see if they have a fix by then, there isnt enough information kept since it hasnt been officially released yet.

I'm having the same trouble. Are you guys on the new sim card? I popped in the new sim card and the tech told me to not use it and just save it. I noticed when I put the new sim card a notification of a new voicemail came on. I didn't have any voicemail.
Edit: I'm starting to have some serious data issues. I'll get cut off, but my phone will still show full bars and "H". I try the whole airplane thing and it still does nothing. I constantly get the "check network setting, try again or cancel". My market wont load, browser says "unable to connect." This is getting stupid. When I call T Mobile it always start working and then cuts off shorty after hanging up. I've never had this isssue before. I live in the middle of the city. Only 3G around here. Its getting annoying.

Guys I'm afraid that it might problem with the antenna placement. Holding the phone on the bottom half will drop me from 3 bars of "H" to 4 bars of "G", then it will bounce back up to 4 bars of "E". If left on a desk then it will remain at 3-4 bars of "H". I notice this especially at a place where I have low-mid signal, such as my school (reinforced concrete FTL). When I have a strong 4 bar signal, it usually won't drop all the way down to edge but I do loose a few bars. I hope a simple software issue is enough to reduce this effect. I might be being crazy paranoid but I'm definitely noticing a lower signal than on my G1.
Try holding the phone by the edges, then hold it in a normal grip and see if the signal strenght changes (Menu->settings->status->signal strength)

I just got off the phone with tmo and was told its a known issue with the network affecting about 10% of users. The issue started for me yesterday on my hd2. He also said they have people working on it. I asked if I could get my buyers remorse set back 14 more days to ensure the issue is not permanment but he said that they are no longer doing extentions. I'm sure if I get tranfered to retentions the answer would change. I hope.

I'm also having the same issue. I just rebooted my phone, so I haven't had the chance of switching airplane mode on/off yet. I'll let you guys know if that works for me, either way, I'm hoping there's a fix from T-Mo.

Wow that's funny, my MYTOUCH does the same thing with airplane mode off/on. I also remember that the store demo g2 I played with last night had the voicemail icon in the notification bar, but when you pull the bar down, there's no option to connect and retrieve the voicemail. I found that even weirder since the phone comes preloaded with google voice.

Also experiencing the same issue here in Phoenix. Been having it since I got the phone on Monday.
I have been in an ongoing round of tech calls and will be having a follow-up with the tech who I spoke with last night... I've tried everything from APN resetting to swapping the SIM card to a total factory wipe -- nothing is changing this for me.
I *know* my neighborhood has full 3G access, but I am maxed out at 1 Mbps. (Before the factory wipe I was getting 0.35 Mbps.) If this doesn't change I may just return the phone and switch to Sprint to get the Epic 4G. I mean, I'm not getting HSPA+ coverage either way, and at least with the Samsung Galaxy S Pro I'd have a full 5-row qwerty...
>_<

Wow, this is really too bad. I was SO excited about this phone...

If this happens, try going to settings->wireless->mobile network->network operators and see if you get an "Error while searching for networks" error as I did.
Reset fixed for me too. But it makes me worry.

I'm on a brand new sim card (switched to TM from ATT). I'm having some data issues too. I talked to TM tech support and they reset my connection but that did nothing. Now they're going to their android techs to see whats up.

[Q] Nexus 4 repeated signal loss and calls not coming through

I've got some serious issues with my Nexus 4, I've found posts with similar problems but not exactly what I have. I'm at a loss what to do next so any advice would be much appreciated.
I bought a N4 around March this year, direct from Google, and connected it to TPG Mobile here in Australia which uses the Optus network.
It was fine until about the end of May or beginning of June where it started losing signal regularly. First thing I noticed is it would start dropping calls and displaying "No network available", the triangular status bar at the top would go blank (completely black, not grey) for about 30 seconds, then it would return to normal signal and I could make calls again. However it would do this every few minutes, whether I was on a call or not, and each time it would last roughly 30 seconds and then return to normal.
Around the same time I started to receive SMS on either a delay, or they'd arrive on-time, but then keep sending multiple times for about the next hour.
I rang Google, they got me to go through recovery mode, then it worked fine, for about 24 hours, before it started again. They sent me a new device, which did the same thing within hours of activation, so I requested a 3rd device. At the same time I thought it might be the sim card, so I got a new one of those too.
My 3rd device and new sim card worked perfectly for about 3 days then the same problem started. Factory resets etc seem to fix the problem for either minutes or hours, but never permanently.
Then last week I noticed further weird symptoms, I started getting the usual sms to say someone had called and left a voicemail, however my phone never showed any sign of a call (visual, audio or missed call in the call log). I confirmed with several people who tried calling me and they confirmed the phone rang on their end before going to VM. I tried it myself from a landline and it randomly rings or doesn't ring on my end, however I also noticed when I hung up on the landline without answering my Nexus 4, it continued to ring indefinitely, ie. it hadn't registered the caller hung up.
My provider assures me there isn't an issue in my area, my wife uses the same provider (with an iphone) and has not had these issues. I can't swap sim cards with her though as she has a full-size sim. I tried another sim with my phone for a few hours and it worked fine, however my phone with my sim will sometimes go a whole day without issues so it wasn't long enough to truly test it.
I've deleted all apps that might somehow affect it and the hasn't helped either.
Basically I'd like to know is this likely to be a phone issue, and I pursue the issue with Google, or some sort of network/sim issue and I pursue it with my provider?

Flashed to Stock Rom, but now have "No Service"

Hello, First time poster, and quite frankly a noob at a lot of this. Here's my issue, i have a at&t Samsung Galaxy S4 that i recieved from a family member that was stuck in a serious boot loop. Only way i could get it to come back was to flash the stock firmware, which worked excellent....now my issue, it seems like about 98% of the time i have the "No Service" icon up top. I got the phone locked through at&t but have since unlocked it to use on Straight talk, as thats what i was originally advised to do by an at&t member (turns out I didnt even need to do this in the first place as ST is just using the at&t towers as a reseller). Unlocked phone, still no service. I had ST previously in a Galaxy S2 in my current location and service was superb, so i know its not a carrier issue. Is it possible that when i flashed stock rom, that i missed something? I checked around and it seems like my modem is updated to the latest setting. When i switched it to ST after about 30 minutes the signal popped up and it seems like as soon as it showed up, it was gone again. Since that point i've been able to make 1 call (I activated ST about 4 days ago) and that call was today, with only 1 bar of reception. Shortly after that call the signal dropped completely again. I am at a complete loss as to why it refuses to get any reception. I was thinking maybe the modem needs to be updated, but the wifi works perfect, and the reception seems to show up (just as 1 little bar) rarely. Anyone have any ideas?

Also, as a little side note, i have done a hard reset a few times and to no avail at fixing the issue. I assume since at certain times i do get the little "1 bar" connection that its not a hardware issue but a software issue thats withholding the phone from reaching potential reception. Any help would work wonders as i've paid the $60 for the BYOP Straight talk.

Which firmware did you flash as the latest firmware is 5.01 and there is no stock rom from att for this version.

If your wifi is working perfect, then modem is not your problem. I have never used Straighttalk but you mentioned that ST is using the AT&T towers so there might be a problem in your simcard registration. Call the ST customer service, tell them your problem and ask them to reprogram your simcard with your phone IMEI. See that would solve your problem.
