[PROB] Diamond GSM Reception too weak - Touch Diamond, MDA Compact IV General

Last few weeks 2 or 3 I have a problem with GSM reception Phone looses a signal at any place even in outdoor. It could espablish to full straingth in a while and then loose again. I notifyed that enabling the WiFi module makes phone to loose GSM signal every time within 30 sec.
I have tried different radios different ROMs in any combinations. Behaviour is similar every time. Even with original ROM it gets disconnected
Did some one expirienced this before? any solutions?
PS. Before las week in the same enviroment everything was fine.

Do you have this problem with other SIMs you put in your phone? And if you try your SIM in another phone, does the signal still appear weak?

Nope i did not tried the different one only mine... will try tomorrow
BTW could is be possible that SIM influences the reception?!?
Will rever with results
All suggestions are still welcome

honestly it's a big surprise for me that replacing sim card with a new one have solved the issue.
Thanks for the hint

After a week of reviewing of the behaviour with new SIM i have to admin that it did not help. It still looses the connection as before.
PS: latest ROM/Radio from HTC aplied with no effect
Any other ideas?

Signal keeps going in and out

Device: Tilt
Carrier: AT&T
ROM: Duttys_WM6.1_Official_5.2.19209_1_58_16_27
Have been running this rom for a couple of weeks with no problem. All of the sudden yesterday I noticed signal kept coming in and out, wasn't able to make or receive calls. Since then, I've tried a couple of diff ROMs, diff radios, and for some reason it just doesn't seem to catch a consistent signal. Signal keeps jumping from 3G to EDGE to having nothing. When I try to make a call or go online, signal just goes dead.
Any suggestions onto what could this be?
Thanks
same issue here....in NYC
i'm having the same issue.
if you switch the band signal (click on the phone icon on the top..then go Bands tab) to GSM. all is well. you will no longer rotate b/w EDGE and 3G when trying to make calls/internet. but when you revert the setting back to Auto, the phone may work for a short time while it still thinks its under EDGE. then when it senses 3G network available, it will try to connect to that signal and disconnect both your voice and data. i'm in New York City, so trying to get on 3G network is not an issue.
ive had this issue for about a week now thinking my setting got all messed up somehow. i've reflashed my tilt to the original ATT ROM from the HTC ATT ROM update from one of Dutty's ROMs. still doesn't work. i'm starting to think the 3G chip is fried...
AT&T technicial support can't help either. the guy i had on the phone said there was a 3G tower literally a block away...
might have to call warranty to get it exchanged...
does anyone else have any ideas why this does this?
Change the radio and see if this helps. I keep a copy of all 6.1 radios on my phone so I can flash on the go for the best signal possible.

I've tried a couple of different radios with no luck. Thing is, it just happened out of nowhere... yesterday morning worked, yesterday night, it was acting up, no change in ROM or radio...
Thanks for your input.

If that is the case, then I would definitely call your service provider and see if they are having issues.

haha... yeah, thats kinda what i figured. so now im "3G-less". im on EDGE only like my old blackberry... at least i have wifi, gps, camera in one device unlike any current BBs out there... still kinda sucks. ill give ATT-tech a shot anyway...
So, I called AT&T yesterday... was on the phone for a couple of hours with NO RESULT! They did they all the towers are working around my area with no problem though... i think it might be what finaldock said, "3G might be fried"
Any suggestions anyone?
Oh yeah, I'm running the ROM below now... still w/the same problem.

Loosing network signal

Hi!
After weeks of flawless function my Xperia can not find my carriers phone network.
I have updated the phone to the new ROM but that does not help.
The phone finds the SIM card and asks for the code.
Strangly it can connect to internet through my carrier (Tele2).
But I can not get a connection to the phone network and make a normal phone call.
Is something wrong with the phone?
NO, cause with another carrier (Telenor) everything works pefect.
Then obviously something is wrong with my carrier (Tele2) or the SIM-card.
NO, cause when I put my Tele2 SIM-card in another device (Ipaq 6515) it works perfect.
The Ipaq is not a 3G-phone. Can that have anything to do with it?
I'm getting lost here, all help is appreciated.
(ORIGINAL MESSAGE
Hi!
After weeks of flawless function my Xperia has started to lose it's phone network.
I notice it after I wake my phone up from stand by mode.
It doesn't help to turn the phone option off and on in Comm manager, but it has sometimes helped turning flight mode on and off.
Other times I had to restart the phone.
This happens a couple of times every day, after long times of not using the phone. I have not been able to trigger this problem, so I don't know what causes it or exactly when it happens.
Strangly it can connect to HDSPA while it has lost the phone network.
I have also experienced som freezes when I'm flipping between the panels to much.
All help is appreciated, thanks.
It would be helpful if you could give us more information.
What ROM are you using
Which carrier you have
etc.

I'm using:
ROM 1.02.936.3
Radioversion 1.06.25.29
The carrier is Swedish Tele2.
In Sweden we have GSM-900 and GSM-1800.
Tele2 also provide me with UMTS and HSDPA.
Today the problem became worse.
Even after repeated soft restarts it refused to find the phone network.
Then I change SIM-card to another carrier and it found the network.
I also tried the SIM-card that's giving me problems in another device. Works fine.
So both SIM-cards works. I'm now gonna go with the new carrier during the day to see if the problem come back.
If anyone have any ideas, please help.

All I can say that Xperia sometimes looks for the signal a bit longer it should IMO,
but I also know that carriers have many many problems usually and they're also often responsible for signal drops in some places too.
I know that 'cos I was talking to my carrier many times about it and learned something about it...
have u tried hard resetting the phone or re-installing the software? ..
if u run the sony update software it will give u the option to re-install your phones software - not sure if that has the same effect as a hard reset ..
probably worth trying

Have you tried disabling 3G/HSDPA?
Chance that you have very poor 3G on your phone, whilst the IPAC is picking up ok 2G.

Thanks for replying.
I disabled HSDPA/HSUPA in the advanced network menu. But it didn't help.
I also tried to choose GSM only in the phone seetings menue. But I could not even change the setting. Just got an error message about not being able to change the network (or something similar).
Is there any other setting that might be worth trying?

Having worked for several phone companies a few years at customer service I know what the procedure is.
-First thing they do is ask you to do a "crosstest", try your SIM in another phone and see if that works.
-You'll tell them that you did that and everything works fine when you use another phone.
-They'll automatically conclude that there's something wrong with your phone (correctly)
-They'll ask you if you could do a hard reset ( You did that too)
-Then maybe they'll try and reset the network (which almost never works)
Basically they'll have no other choice then for you to return it and have them look at the problem / replace your phone.
I don't think we here can help you with your problem
Good luck and keep us posted
Get a new SIM card. I've seen problems like this before, and an updated SIM card solved it.
The best way would be to test your SIM card in a similar phone, the ipaq not being close because it's not even 3G.

I'm so confused right now.
Got my new sim card today, problem remains.
I call the carrier support and after they've looked the IMEI-number up they say that the phone is barred by an external operator. They won't tell me the reason and by what operator.
So I call the other carriers support and after they've done a IMEI-search they say that the phone is not locked in any way, by them or any other operator. After have been talking to Xperia support they come to the same conclusion. The phone is not locked but agree to that something is wrong, with phone or carriers, and they want me to try with a third carrier.
Final
I've handed in my phone to the seller and got another one back instead.
The end
Exact same problem
Howdy folks,
I have the exact same problem: My Xperia has worked fine for a month. Suddenly I can't register with Tele2 network (tried another Tele2 card as well that didn't work) for calling but have access to data channel so I can surf. Got told by the Tele2 support that my phone was fu**ed up. Got pissed off. Tried a sim for another provider (Telenor) that worked. Called the Tele2 support again. They noticed that I have an old (2g) sim, so they will send a new (3g) card to test if that fixes this mess. It should arrive late this week or early the next. Can't wait...
I'll keep you posted in this thread (or, if I should instead have made a new thread, a moderator may spank me and I will do better).

Nope, new sim-card didn't fix it. But I have found at least one other xperia-user with this problem...
bad GSM signal
I have a X1
rom 1.03.931.10
radio 1.10.25.18
protocol version 52.56.25.29W
and since from the start I have bad GSM signal I have like 1-2 lines onli and it go up to 5line but onli from time to time (and then it drops again to 1-2line or none but If Itray to call is working or I get called but I can berly hear them bicose of the bad signal) on O2 network and in T-mobile is the same no mather wher I'm in town or outside of town; I'm in UK
is the phone damaged?? or...
sry for my bad english
My phone does the same thing
My x1 has had no problem with phone function or network. However, from the last week, the signal began to be lost sometimes, and the machine turned off automatically. and finally today, there is no signal at all.
MY SIM card works with other phones, so, I thought it might be software problem, and hard reseted with new rom. However, still no signal. It keeps looking. Does anyone have the same problem, and hopefully, solution?
I´m using my X1i with Tele2 as my service provider,but i don´t have any problems with signalstrength.. Works just fine..

I know I should've introdouced myself first, and that this is a strange first post, but:
HOLY SMOKES!!!
Xperia has FIVE reception bars????!!!!!
I always thought that 3 is the max value, since it only happened once that it went up to three bars, rest of the time it's maximum 2, usually 1.
I am also on Tele2 carrier, in Sweden that is, and since yesterday, I have no reception AT ALL.
Nothing.
Tried turning off 3G(or whatever it's called), nothing happens.
Tested with 3 other cards (one Tele2, one Telenor, one Telia) - all seem to be working okay. Except that the Tele2 one has slightly lower reception than the others.
Tested with 3 other phones as well - iPhone 3GS, Nokia 5800 Xpress Music, HTC Desire. All of them worked perfectly. Full coverage on that super-fast network thingy(the 3G symbol on iPhone).
Internet is just flowing on other phones - but Xperia is just falling behind in the most important section - reception.
Calls get dropped (2/3 of the calls), I must send same message at least 3 times in order to get it sent, Internet is crappy - if there's any at all.
Any kind of guidance is mostly appreciated.
P.S. A bit of those numbers which seem to be important:
Microsoft Windows MobileR 6.1 Professional
CE-OS 5.2.19608 (Build 19608.1.2.60)
ROM-version: 1.05.936.9
ROM-date: 04/19/09
Radioversion: 1.14.25.55
Protocol version: 1.0.11842.32680
Since all of you seem to have problems with one and the same carrier (Tele2) why don't you simply switch to another one? I once had a problem that was very alike the one described here and after several unsuccessful attempts of the carrier to fix it I simply switched to another one and all my problems were gone.

Dropped signal on v1615 t-mobile uk

I have a strange problem with my Kaiser, the signal with t-mobile uk keeps dropping, I have changed various radios and roms but still have the problem.
Current Phone is: V1615
KAIS130
SPL-3.34.Hard
CPLD-8
Current RomDA Ultimate X-V3 (but have tried anumber of others including stock t-mobile)
Current Radio: 1.70.19.09 (but have tried a number of others)
Any help would be appreciated.
p.s. Yeah on my first post, been a lurker for far too long.
Do you use 3G networking?, if not, try to change under Band menu to GSM network, it works pretty well and most places has good signal for it.
Good Luck!
I've had a nightmare with mine on T-mobile..
3 months ago, my phone developed a problem where it'd drop its network for a few hours, then I'd get a few hours of it working, etc. etc.
It was sent to T-mobile, who just re-flashed it. Still didn't work! Had it sent back and it was away a long time, I believe they replaced the motherboard.
It's been working perfectly for the last month until today - When it hasn't had a network connection the whole day! I'm worried it's still broken..
Hopefully our problems are network based! T-mobile warranty returns are terrible.
Aha! Changing my "Network Type" to GSM from Auto fixed things.
...But now when I receive a text, it vibrates until I reset!

turn off vibrate
Hi Milmirex & Jamiepyrite, thanks for the comments.
I've changed to GSM and it has been working fine for the last ten minutes, will test for the rest of the day and report back.
Does anybody else have any idea's how to fix 3G problem? I receive emails all day so could really do with this being resolved.
Does anybody else have same issue but with different network? would possibly point to hardware issue if you do.
Thanks again.
P.S. I didn't have the problem with vibrating on receiving texts
I had flashed back to the original T-Mobile ROM when it was doing the vibrate thing. Flashed it again back to the ROM I was using before and all works fine now

Even I have the similar issues from last week. Mine is MDA VARIO III. Even after changing my band to GSM, the issue stil seesm to be there. For about 10 mins i get a weak sigmnal, then it disappears.
Where did you get the original TMobile Vario III ROM. I would like to reflash and see if it fixes the problem. Can you please direct me to the right place
Thanks

I think my problem may be similar. I'm with Virgin Mobile but I think they use T-Mobile network.
Have had my Tytn II for over a year & haven't touched software or settings for several months & all has worked well. For the last few weeks I've had no signal in places that other people on the same network (using different phones) are fine. Sometimes if I reboot it comes back. I'm also now finding low battery a lot but I think that the signal issue is draining my batter as it seems to be constantly searching. I get low/no signal with a completely full battery so I don't think that the battery is the problem.
Might this be a H/W problem? Anything I can do to sort this?
i have the same problem. I use Telkomsel operator in indonesia. My Kaiser is HTC Brand.
Any idea why is this happen? Seems like A LOT OF Kaiser went bad this way
Anyone have solution?

Yup bro, we had the same problems,
i had already try to use with XL, Indosat, and my own Telkomsel,
but still had this serious problems,until i switch phone mode into GSM
i use this gadget for 3G purpose now i must use only GSM
is there any solutions from HTC? I already count on the net and found a lot of problem like we had and still no solutions from HTC

WEIRD! Emergency call only! O_o

This one is pretty *beep* up! The phone was working pretty fine last time I looked at it (30 minutes ago), I put it in my pocket and had dinner (as always), then I took it out to make a phone call and it says just "Emergency call only" instead of showing my phone operator (3 ITA). I tried rebooting, no luck! Still the same.
Strange thing is that it has signal (full) but I can't make/receive calls or use data network. If I go under Settings -> Wifi -> Mobile networks settings and I look for operators it searches and I can see all of them (mine included) but I cannot select it!! Neither mine nor another one (TIM, which is the roaming default one for my operator when there's no signal)...it just says "Unable to connect. Try later".
Weirdest thing of all is that I AM RECEIVING PUSH EMAILS from gmail!!!
Anyone has a clue about this??? Has it ever happened to anyone?
Btw, I'm using zeroblaster rom, which is based on official italian froyo firmware...everything was working so good until ten minutes ago!
Hope I don't have to reflash...
Just got weirder: put my sim on another phone...it registers without problems on the network.
Then put the other's phone's sim on my sgs...it registers without problems.
Then switched again: Emergency calls only
WHAT THE ****??!? (what are we? children? sorry mod...lol)

It is WAY weird imho! The weirdest thing being that I'm still receiving gmail's pushes after 5-6 reboots while it keeps saying "emergency calls only".
Also I saw that when the phone boots, while it's loading the launcher, widgets, etc. it gets the connection for like 2-3 seconds it shows my operator (in the lockscreen), then it switches to "emergency calls only"...
I'll wait another hour (maybe as the issue came out of nowhere it'll go away? ) then I'll try reflashing...since I had to change to k9 anyway to fix the /system corruption etc. -.- I'm already backing-up...
Hope the flash will fix this though...it's really a pain in the ***

No that's not it, because putting H3G sim on another phone WORKS!!
And anyway, when H3G's down it uses TIM as roaming...this time I cannot even select TIM as operator, it refuses! And normally you can always use tim in roaming if you want (even when H3G has signal...)!

Hmmmm... That is weird alright.
If you purchased your SGS through your carrier H3G I would still call them to report it as there are now 2 of you experiencing the same issue so it cant just be phone related and if it is then they will have to honor your warranty to replace or fix it (both of you)...
It's happening to me too.. i also use H3G Italy on my Galaxy S and i have this issue since around 19:00 this evening with my work SIM card
I have a Tayutama 1.0.0 ROM based on the JPM Froyo ROM.. it's the first time this is happening to me..

Well... That is 3 of you so it must be carrier related in some way. Again... Call your carrier and explain what is happening. Explain that when you put the sim into a different device it works ok but in the SGS all you can do is make emergency calls and they should be able to tell you what is going on.
Make sure to post back as I am now interested in seeing what your issue is / was...

You just answered your own question I think. "service state: out of service" says it all I believe even if the sim cards DO rgister on another phone for whatever reason.
The fact is the they dont register on your Galaxy S so call them and report the issue and they should be able to help you...
Yeah well, you see, that could be a problem because...H3G has a TERRIBLE customer care, lol! Basically the thing is you can't call them...you need to send an email, and an answer will arrive 2-3 days later. That's not good enough for me! If it doesn't get fixed tomorrow I'll go directly to a 3shop and they'll call someone higher to understand this. Hope they fix it soon though!
Anyway...now I have a strong curiosity: could it be JUST the SGS? If so...WHY???? I tried putting the simcard on a Nokia E71 and it works...does anyone have another android phone with H3G? Could it be somehow "system"-related? Because I can't figure out why a specific phone device shouldn't work point-blank with my operator! And that's even a phone they sell themselves!!
Rebooted and now it WORKS! THANK GOD (even if I'm atheist....)
Still would like to know why it did this!
I had a similar problem where if I was in an area with bad reception it would default to emergency calls only. But the funny thing is when I go into the menu settings I can see my carrier and when I try to select it, it says network unreachable. Eventually I would get signal but the tab still says emergency calls only. Tried making calls but it wouldn't allow.
Initially to rectify the problem I rebooted the phone and that worked but got annoying. So I realised that if I left it for a couple of mins whenn it had reception it would fix itself. As of recently (last 2 months) I haven't any problems.
Btw i'm on jpm and my carrier is 3 australia. It's rubbish service

Hello,
Same thing happening to me... It must have something related to signal strength, i went downtown and phone was perfectly fine.
But at home it keeps loosing signal, i dialed *#*#0011#*#* and it shows changing BAND... as if it was searching for service on different bands...
But the thing is, i tried inserting the SIM on other 2 phones and i get a FULL signal, so i guess signal is coming pretty intense here... why is the SGS loosing it? i have no idea...
By the way, i am from Brazil, and that started happening after i flashed my rom to FROYO VJJPA..
me too, has no signal at home but works for another phone.

Same is happening to me. Serive state says out of service so could registering the sim card to phone be the actual isuue?

[Q] N7000 3G Radio failing

I've had my GT-N7000 for about a year. It has been rooted and running various ROMs since I had it and has always worked wonderfully. I had settled on CM 10.1 about a month ago. Since the last 3-4 days I noticed that my 3G signal showed no bars from time to time. Normally, just a quick 'airplane mode' dip and everything would be fine.
2 days ago was still having the same problem and I had to completely turn off and on again to 'maybe' get a signal. If I got a signal, it would only stay there for a few minutes and then disappear.
I changed the SIM card yesterday just to be sure but I still had the same problem. The same SIM card works perfectly well in my GT-I9000 running CM 10.1 as well.
I cleaned the SIM slot contacts, verified the internal antenna wire and even flashed a few modems and still have short lived and intermittent 3G signal. Any idea about what could be happening? Could it be the 3G radio failing on me?
Thanks for any help.
JF.
Anyone?
Does this happen after you move from one area to another? For instance from work to home or Vice Versa?
same problem
Hi there,
I've got the same problem than you. I got my Note 1 year ago, and since few days, I've a problem with the SIM.
On boot or reboot, the SIM is perfectly recognized and works good. I can call without problem, and can connect to the wifi without problem. The problem is when I use 3g, the SIM is not recognize after 1-2 minutes. I mean, I can access internet, do whatever I want, for just a minute or two. After that, the signal drop instantly. I tried:
plane mode: doesn't come back to normal mode cause the phone says there no SIM card
change modem: don't resolve the problem on all XX*** modem for JellyBean
change ROM: I was on German-leaked 4.1.2 Stock ROM, i tried 4.1.2 Switzerland ROM (where I live), 4.1.2 custom ROM and cynogenmod 10.1 (4.2.2). Always the same problem.
Tonight I'll try another SIM in the phone, in the case that the SIM is the problem.
otherwise, I don't know what else to try...

You're ****ed if it's the same problem! I tried a lot of technique and the one I warn you about is changing the RIL. Useless waste of time and ****ed up everything. At the end I tried an app available on the play store for thé modem, can't remember which one. But hey, you're on the track!
Good luck

Are you sure it is the radio causing the problem and not the antenna? I know on mine, the USB charge port can be a real PITA when it
goes bad, and I had to buy about 3 before I found one that worked properly. With the wrong one, the radio signal would fluctuate all
over the place, so that's why I wonder if it could be a bad antenna/connection/board problem, since it is contained on the same
board as the USB port?

I had an update..
I figured out that when i change the network mode to GSM ONLY it runs very well and never drops network signal or get the NO SIMCARD message..
but when i change the mode to AUTO or 3G/CDMA it drops network and gets NO SIM CARD after a few minutes !!
still don't know the reason & still searching
Let's talk about this problem. Mine is similar. Not getting errors with aim card but when i place or receive calls while in wcdma mode, conversation is normal at first place, then after few seconds i can not hear other side, and other side cannot hear me, sometimes that call ends and that is it. On gsm only, calls work normally, but internet is not working, while in wcdma internet works... pretty nasty issue. I tried flashing different roms, tried several modems to flash, problem is not disappearing, but from modem to modem i can see improvements. Sometimes it does not drop at all... can you help me with this?
