Loss of signal when sending SMS/MMS? - G2 and Desire Z General

Everytime I send an sms/mms my phone signal drops completely. Sometimes the messages send, sometimes they don't. I even tested this a couple times sending myself a text....anyone else experiencing this?
And yes I have tried restarting.

I've experienced this too, but only when I already have a pretty low signal. It never happens when I have a good signal (not based on the notification bar, actually reading the dBm).

ive had this issue with every tmobile phone i have ever owned. even my nokia n900 on tmobiles network had this issue.

Whenever I'm in a car or a bus, I tend to lose signal or even the data connection. It shows the bars but no data activity, and or loses the five bars and is empty. Ill go in phone status and check the phone signals are all 0. This just started happening, I'm going to give tmobile a call.

this may sound dumb, but could it be the way you are holding the phone? much like my nexus one, i find that when i hold the phone landscape my right hand willc over up the bottom of the phone where the antenna is and my signal drops. depending on how weak it was to start, sometimes i kill my signal. my G2 isnt as bad as my nexus was but it still happens sometimes ive noticed.

It is not an iPhone!
No but it happens anyway I hold it. Landscape or vertical, it loses signal even when I'm at my desk in class and not moving it will drop signal and then take abour 5-10secs to get the signal again.
And also I realized that when I have 1 bar, it will lose signal and then get 5 bars. I'm thinking it doesn't do good at holding signal and transferring from tower to tower.

Lol. Its not the way I'm holding the phone. I'll have full bars, then soon as I click send, I have none....then it goes from E to H.

Only when roaming or on EDGE
I have only had this happen while roaming or on an Edge network. We are very fortunate in Lubbock to have HSPA and GPRS, only a couple of towers are pushing edge in this area. Usually once I return to a G or H, SMS/MMS goes through with no problems... May have something to do with the Radio Issue, the alleged ota will fix...

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.

No internet on edge PERIOD!!!!

I hate to ask this........if its in another forum or not but do you guys have the same problem running your internet when you are on edge. What sucks is my house switches from H to E and when on E there is no action. If there are others let me know cause I this is my second phone already due to black screen.

Same here, in southern Arizona. This is also my second phone. First one bricked mysteriously I can't access the app store or do ANYTHING data-related in EDGE mode. 3G works very well, but I get nothing whenever I'm in EDGE. At least I have wifi at home.
I've called customer support and their recommendation was to do a factory reset. I tried that, no improvement. I get slightly more stable connections after changing my radio to GSM (auto PRL) in the phone information menu, but it's still awful.
I'm thinking of calling back again in a week or so and bugging them to give me a third phone. Maybe the second batch with tighter hinges will be out by then...
I am on my third G2 and all of them have had much the same issues. All have had loose hinges. The last one I received started out by rebooting on its own as I charged it. With my Nexus One and my Vibrant I always get 1-3 bars of 3g with the G2s I get virtually no H consistently or 3g and 2-3 bars of E or a lot of G. This last one will go from suddenly having 4 bars of H to 1 bar of G it just does not stay on H and I get numerous No signals. Getting on the market at times is frustrating and downloading is a real adventure. I like the phone but am becoming disenchanted as it seems with this last G2 I am uncovering different problems every day. I have had black screen freezes random reboots etc. Also while in a conversation on the phone it put the call on hold without my doing anything. Perhaps the sensor malfunctioned and my ear hit the hold or mute button but this should not happen. I have also dropped calls and have had calls come in with no notification except for notice of voice mail after the fact. I am about ready to throw in the towel and send it back for a refund. If anyone has any ideas or fixes for any of the issues I have mentioned I would greatly appreciate hearing them
Just had a screen freeze and when it booted backup by itself it just went into a loop of home screen to black screen and home screen to black screen. Had to power off and pull battery and reboot and it now seems okay. That probably does it for me. I am tired of the constant problems and after 3 devices all with similar or same issues and more being uncovered every day,I am coming to believe that another replacement will not be the answer.
Yes this happens to me pretty often. I live in a building in Brooklyn NY, and when I am moving around in the building, my data connection goes out and I get 5 bars of signal but no data, no G, E, 3G or H+.
Also if I'm in an area where data connection or the signal is spotty, it will go from H to E and then back to E, and then give me a error about not being able to get any data connection.

Sudden Drop signal

In the past few days, I've noticed my phone sometimes loses signal randomly: the bars will turn dark gray (not light gray) and there would be an "x" over the bars. Def. no "3G" indicator.
And it's happening in places where I normally get signal. A reboot doesn't fix this. I just have to wait until the signal is back up. I haven't installed anything new recently, nor am I running anything out of the ordinary.
Anybody else experiencing this as well? I did a quick search and wasn't able to find much.
I'm still on 2.3.2 (haven't gotten the OTA), unrooted.
I also experience this loss of signal. Constantly. Every time during a call.

Just to clarify, this isn't happening to me during calls, or hasn't happened to me during a phone call yet. Sometimes I pick up my phone, and I see I have no signal. And of course, attempting to call out or access gmail/internet proves it so.
It's very frustrating.
2.3.3 comes with a updated radio.
You can also fastboot the updated radio but your phone isn't modded.

I will need to clarify myself too, I meant I always lose the data signal every time I'm in a call. As for the phone signal (bars), I have no issues.

Are you on EDGE (2G) or 3G or WiFi when that happens? EDGE does not support concurrent use of voice and data, but the other types of data should.

Data dissappears during phone calls? Realization time

Has it always been like this? Flashed a few roms and radios. But I think I never really thought about it or noticed it until now and it's really bugging me. I've read a few topics about 3g and 4g being "parallel" to our voice calls so we can't have both? I don't quite understand any of it.
Can someone tell me it's just my phone so I can try to solve the problem, or reassure me that we can't have both at the same time so I can sleep better tonight? lol
Thanks for any and all help!
Edit: Sorry meant to post this in the question thread.

ALL GSM phones that are connected to HSPA or greater should be able to talk and surf at the same time. I do it frequently personally. Do you know if you drop to EDGE/GRPS when you get on a phone call?
I am also having this issue but its strange that the guy posting above me does not face this issue - may be it is a hardware issue like screen and emmc since I already tried different roms and radios?. As soon as I am in a call I am disconnected from network data. I noticed only recently when I was in a hotel room working on my laptop (tethered phone to provide internet) and just when I joined a conference call, I lost internet. It was so embarrassing I couldnt curse tmobile and htc enough. The iphone ad about talking and surfing at the same time never made sense to me before this incidence.
my phone does this too, but its on and off. Sometimes it does, others it doesnt. I really have no idea what could cause it.
Let me shed some light on this....if you are on H will less then 2 bars and theres an E with 3 bars or more and u get a call the phone will switch to E but once you hang up then its back on H. But if H has 3 bars or more when a call is received then I will stay on the H network and allow talk and data at the same time. Theres no hard ware issues trust me. Hspa is preferred but if there is a stronger signal then the phone switches. I hope that makes sense. You can not do data and talk together on E but you can on H.

Or, to put it in other words: when the phone is in a call, it'll hop to the "best sounding" base station, and if it would happen to be the old GSM/GPRS/EDGE base station - the data will drop. The missing bit is: once it drops - it isn't re-negotiated during the call, only after it. Thus, if the phone hops to EDGE base station even for a second during the call - you won't have data from this point and till the end of the call.
Perfectly normal behavior.

This is definitely not the case. I have tried multiple times with different signal strengths but it drops completely every time. I just did another test, I was on H at 3.47mbps with all full bars and as soon as i placed a call to my friend, the data dropped completely.

It's not about the bars you see, but the signal strength (and not only) your phone sees - which is way more complicated than just bars. Read my post above.
And it's not an opinion either, it's a fact. This is how cellular handoff/handover works. http://en.wikipedia.org/wiki/Vertical_handover
Thanks for the replies and insight everyone. Now I know a little bit more about how that handover works heh.
In my case, most calls were made from my office building. Yesterday, when I posted, I had the newest radio and data would drop immediately as soon as the person answers my call (not a steady drop from 4g-3g-Edge, icon just disappears completely). At best, I was able to download a few apps during a call (which was downloading before the call was made) but as soon my screen locked and turned off - the data was gone on wake and wouldn't turn back on until after the call was finished.
Went through 4 different ROMS yesterday with about the same results but I have recently reflashed RoyalGinger again along with the stock radio thereafter and it seems to be holding during calls, even on my ride to work this morning. I know this is against what most people have said in this thread but maybe I just messed something up on my phone with the new radio? Guess I'll stick to this radio for now. Thanks again everybody.
Radio is the one responsible for determining the best possible connection, and flashing new radio might change things.
I'm in a good 3G/H coverage zone, with new radio, and just tested - the data remained on during the call in any conditions, screen off, screen on, wifi toggling - still worked.

When I'm on 4g and turn the screen off the data turns off, normally after an extended period, which its good for battery.

This has happened to me since I had my blackberry 9700. My experience has been that it loses all data (H/3G/E), even in good H/3G signal area and won't reconnect until I end the call. However the data loss only occurs while on a call. While not on a call, just surfing the net or using data any other way does not cause lost data connection nor a drop from H/3G to Edge. I saw somewhere on these forums that switching to H/3G only will prevent this from happening. I've tried this and it seemed to help, but I haven't been checking on every call.

[Q] Signal bar goes from full to nothing randomly

Ever since I got a replacement phone Ive had this issue- while on the Sprint network my signal will randomly go from full to nothing at all. Yet when I use roam control to go into roaming, the signal always stays at full strength
The other thing I noticed is that when I dial into the 3282 menu, someone elses username is there instead of mine. When I run connectbot and use getprop, no MSL # is there either
Anyone know whats going on with the phone and if this can be fixed?
getprop ril.MSL
It is filtered from just getprop.
My signal has always done that.
Updated profile may fix the user name?
Sent from my SPH-D700 using Tapatalk
Thanks that command did the trick to get the msl- I was able to go in and manually change the username now.
Is there any settings in the data menu to improve the signal? Its almost like its jumping back and forth between a good and bad tower?
Not that I know of. That is what I suspect is the case with me as I have about 3 towers that are surrounding me from various sides and I think it is hopping between them... not sure there is anything to do for it but I haven't really seen any ill effects from it.
Sent from my SPH-D700 using Tapatalk
The weird thing is it never used to do this before when I first got the phone. When I was in the same areas the signal bar was always full and would never drop. I wonder if its a tower issue or something they changed with an update.
Sometimes when people call me they say it goes straight to voicemail though which worries me
Could be the modem. Some people think el30 is not as good as ei22 or ec05. Maybe try some others.
For calls calls going to vm, that can happen if you are using data in a 1x area. Also can happen if you have accidentally switched on ddtm in call settings.
Sent from my SPH-D700 using Tapatalk
This is going to be plain and a tad bit retarded but a solution is WiFi, as far 3G and 4G mine has always done this but i can testify that in my house i used to get ****ty service like 0 to 1 bar when i was on EC05 i switched EL30 now to FB15 and say much more improvement more consistent to 3-4 bars.
PRL updates could help if you roam around there. newest as of today is 60685
I've been having this problem too for about two months now. But as you said roaming works fine so I just assume it's a sprint tower issue and force roam whenever I'm on wifi.
I have had this issue for a year or so... started a while after I first rooted.
You can hold my epic in one hand, my wife's epic in the other... her bars stay steady, maybe fluctuate between 2 or 3 bars occasionally... mine randomly and erratically jump from 2 or 3 to nothing, stay there for 30 seconds or so... and jump back up.
While its annoying and distracting, I've never had a problem with dropping calls or losing data. I even took the phone apart to make sure the antenna had not come loose. Problem persisted over several roms and several modem Odin flashes, just won't go away!
Mine does the same, it'll have full bars, drop down to nothing, but my 3g/4g still work fine (off wifi)... i just ignore the signal bars because most of the time my data still works, albeit a tad slow.
