1.93 ROM cant find any network

I recently updated my ROM to 1.93 with Radio .05 and now my phone is not finding any service, it just has the ! mark on top. I went into connection settings and used both manual and auto settings and it cant find my t mobile network. I am using T mobile in the US and was wondering if any of you had any suggestions. Thanks for your help

hi,
did u find other providers or is the list completely empty ?

try the following 3 points of success
1)just try whether you can make a emergency call
2)hold your diamond to a speaker in your near and listen whether there is a strange noise(turn on the speaker loud)
3) if you had another pda try the sim in the device
post the results....

thanks for the reply bro
in my area, t mobile and AT&T show up as networks but my phone will just not connect to them, its just says "searching" and stays that way
1) is 911 the only emergency call you can make cuz i really dont wanna get in trouble with the law you know haha
2) i do hear a strange noise when i turn the volume up
3) i put my sim in my old n95 and it works just fine
its like my diamond is not even detecting my SIM card, i put my friends AT&T SIM in it and it doesnt detect that either

just read this http://forum.xda-developers.com/showthread.php?t=434950
i've also got such a strange problem but now all works fine...
and btw at this crazy time i put my sim in a old nokia 3310 and he found
a network immediately then i put it back in 3 different pda's (all of them are working up to 100 percent) and all 3 devices found NO network...
at this time iam also going really crazy and desperate
i dont know the reason for my success, i just let the simcard over the night in a other pda and on the next morning magicaly all works fine...
can u choose between gsm and wcdma?

just do this
select the automatic provider pickup and the wait over 10 minutes...
when he found a network after a long waiting time try connect to gprs.
if gsm will work and you can call someone and gprs will not works simultaniously u know you have the same fun like me

Okay ill take a look at that, and yes I can choose between Auto, GSM, and WCDMA. I usually leave it on auto, but even when I switch to GSM it does not pick anything up.

holy potatoes i dont know what i just did but it worked!!! i put the SIM in my old N95 and it found the t mobile network. i sent some messages, made some phones calls, then put the SIM back in my diamond and it found the network!! wow thanks a bunch for your help bro, i cant thank you enough

okay scratch that it worked for a little bit, until I started installing some apps and had to restart my phone, now it cant find a network again when it booted back up. Is it the apps that im installing that might be causing this?

no man i dont think so...
i think that was a mistake by the sim or by tmobile self (i think if they have any problems, they didnt say anything to their costumers )
if you have the possibility to go a little bit away from your home, for example into downtown then do this and test if u get there a signal.
i live in vienna - austria. vienna has 23 districts - when i had this terrible problem - at least in 7 disctricts i became immediately a signal and in my own district i became to no time a gsm signal (or more accurately described - i became a gsm sigal after 5-10 minutes waiting time (every time i turn off and turn on the phone, always i had to wait about 5-10 minutes) then i could make calls but no internet connection was possible. but in the other 7 disctricts where ive been, all works fine

thanks for the help man your awesome, i really appreciate it. but i think ive finally found the issue, when i restarted the phone it couldnt locate any network. but then i started to charge it and boom!! it found it again! so does the battery need to be near full for it to locate a signal? haha wow, craziest phone ive ever had!

thx - i do what i can
but i dont think that the problem is gone - you will see - it wont work long. i signal must be there - it should does make no matter whether the battery is - not load - half load or full loaded. it must always work! at 1% of battery it works on my device - it is impossible that that is the problem of you. go to the next tmobile store and let change your sim card - or make it like me - just wait 4 days - hope tmobile have fixed their problems - and be happy if it works.
otherwise it was a hardware issue and you have to send it back to tmobile for repair. but if you do this you must restore the stock software... otherwise you lose your guaranty!!

oh i forgot to say in the first post that my diamond is unlocked, im just using t mobile as my carrier on it but my phone is not locked to any network. so im not sure if its t mobiles fault but just my phone. My SIM card worked fine right away when i put it in my N95 8GB, but my diamond did not pick it up right away when i put it in. I had to plug in my charger first then a few seconds later it found a signal. Not sure why it did that, maybe just needed a little boost to grab that signal or something. Could it be the ROM or Radio I am using?

ok, then send it back to htc, or bring it to the store back where you bought it.
but do this only if you really see no more chance to fix it...
remember what i write, i try my sim in a nokia 3310 and it works, a few seconds later in diamond and 2 other pda's i got no network - back in nokia and it works i dont know how this could be possible!!!
i also try 5 different roms and all radios that exists too - and with all was the same - just nothing.
its your choice my friend - be patient and hope for better times or send it back to repair. but then also upload the original htc rom, radio and spl
i go now sleep - at vienna its 23 o'clock iam verrrrrrry tired from a hard working day...
but post further results, i read it tomorrow...

same here
i have a very similar problem.
i can only make and receive calls on the wcdma network, but not on gsm.
in both, it says that i have reception, but when i try to make a call it just goes silent and after a while the call is ended.
if i dial *102# which is the number to access your mobile credit status, on wcdma it opens a little bubble coming from the network icon and says the correct values, on gsm it simply waits and says connection interrupted.
i have tried several roms and radios, and the problem persists...
you can view my current setup in my signature.
any ideas, what could be the problem? is it the hardware? does this have to do something with hungary?
the sim works just fine, since 1997 (i have no idea how can 3g work on this little baby, but it does) =D
any help appreciated! tx

hi,
i was really wondering why this strange problem happens now on more and more users... thats really interessting....
did you try the sim in a other phone?
if it there also not work -> go to a store from your provider and told them that u have a old sim card which not works with your current phone.
normaly they should give you immediately a free new sim card.
and please tell me whether you have tmobile as your provider.
just for info because you write, that u can use 3g.... when i recieved my diamond i also had an old sim card which doesnt support UMTS or 3G but HSDPA was working, that cause because the sim is not responsible for this communication mode - only your phone!

the problem the guy has in this thread is almost exactly what i am experiencing right now
http://forum.xda-developers.com/showthread.php?t=409733&highlight=network+problem
except mine used to just keep restarting an wouldnt boot up so i just let it do that for about 10 min and it eventually loaded up. Is there a specific number I can dial that will reset my SIM card settings or something? My phone has been like this for a couple days now and it sucks not being able to call or text anybody.
I thought I solved this problem when I plugged in my charger to my phone, then it started finding the EDGE network but my signal was still being dropped when I made calls, only some text would go through and thats it. Please guys, somebody save me from this misery!

Okay, nope not fixed... Flashed it with 1.37, connected to the network for a few seconds, dialed somebody and no ring or anything, but when i called my phone i could hear my own voice. So I guess i have to send it in for repair. Damn.

at this bad time i also restore to stock rom 1.37 and he found in 1 second a signal BUT then it was also impossible to make an internet connection...

ya i was starting to think it was tmobiles problem until I put my friends AT&T SIM in and it was doing the same thing. It would just say "searching" and thats it, and well I just charged up my phone to almost full battery and it located a signal again. But it still drops calls almost immediately and I can only send text. Does the 1.93 ROM do anything to the Radio or antenna because it has been like this even when I flash back to earlier ROMS and radios. I am almost sure that flashing or changing radios will not solve the problem because I have done that countless times already.

No Service ("Searching...")

Yesterday my HTC Excalibur stopped receiving calls, text messages and would not make calls.
I turned the phone off, took the battery and SIM Card out, put it in 5 minutes later hoping it would work again, it did not.
I did a reset of the phone (accessories, clear storage, 1234), that did not work.
This morning I tried swapping SIM cards with someone else (to see if was the service provider). Both SIM Cards worked in my friends Sony Ericsson but neither worked in my HTC Excalibur.
I have the 3V0 Windows Mobile 6.5 installed.
Is there a way I can fix this?

No, I don't know how.
The phone came with it installed. I bought it new, but the seller installed WM 6.5 before shipping, so it's more like open box.
How long does it take? Should I leave that as a last resort?
Is there anything I can tweak on my phone right now?

EDIT: OP shared more info related via PM, thread re-open.
As I sent you via PM, hard reset or reflash your device. If that doesn't work get a new sim from your carrier since it can be network related.

reflashed to 6.1 but still no luck.
Again I tried another working sim from the same carrier, both sims work in my friends phone, but neither work on my s620.

I'v been in contact with jockyw2001 for his Excalibur Sim Unlock.
I just don't understand why I have to pay someone for this, I just bought the phone less than a month ago and it's been working perfectly.
How did this happen? How did my phone get locked?

Yes, the phone radio is on.

Now sometimes it says Rogers Wireless rather than searching.
But when I call someone, it does everything but complete the call. It just beeps twice and says 00:00.

jockyw2001 says my IMEI is unlocked.

Hey guys,

I filed a claim on eBay. That seems to be the best option.

[Q] [help please] Your sim card does not allow connection...

Hi guys,
ok... I have an HTC desire... originally on Virgin Mobile and now unlocked. I'm an O2 customer...
I have rooted and installed the Leedroid rom... originally at version 1.8b. Everything was fine.... until I had a corruption on the SD card.... which I fixed when I got a second following a couple of days of "mounted read only." A day or so later, I lost connection to the O2 network and have been unable to regain it, despite several ROM (I'm now running Leedroid 1.9) and radio reflashes.
I still have access to wi-fi, gps etc.
I have tested my sim card in another phone (all ok) as well as other sim cards in my phone (doesn't work.) I have also swapped and tried another O2 sim.
The phone detects all the major networks... just won't let me connect.
The error message I get when trying to connect to a network manually is "your sim card does not allow a connection to this network"
I've obviously checked that the phone isn't IMEI blocked etc. I've also tried the sim unlock from the fastboot menu, the switching on and off of the radio, airplane mode... lots and lots of stuff.
I really am at my wits end with this issue. I love the desire... but it's obviously of no use to me without the phone element!!!
Can anyone please suggest something to solve this problem???? Could the corruption of the sd card have caused this in some way, despite several rom/radio reflashes since? I really want to stick with the desire, but at the moment I effectively have a £400 brick....
Thanks in advance for any help you might be able to provide.....
Shep

Firstly this is not a development issue, its a question.....
But anyway, when the phone is telling you that you cannot connect to the network is it allowing you to enter an unlock code at all? Or have you ever "unlocked" the phone in the past?

You're right Lenny... apologies for creating the thread in the wrong part of the forum.... perhaps a mod could move it....
Yes... the phone was unlocked from Virgin mobile prior to me buying it [from ebay.] I didn't perceive this to be an issue, given that I actually had connection to O2 for a day or two before losing it...
No... the phone/sim is not asking for a code when I attempt to connect.
Thanks,
Shep

and did it stop letting you on randomly, or did you do something immediately before?

Nope... completely random. I was in a poor reception area and initially put it down to this... but then it never returned and I'm now back at home having had zero connection for a week.
I think that my repair of the SD card was after I initially lost connection. But as I said, I'm not sure whether the SD card corruption is a red herring.

Call me sceptical, but I doubt you would of been able to check whether it was on the IMEI blacklist or not unless you worked for a phone network.
It's not public knowledge and someone working for O2 shouldn't have told you if it was or wasn't.
Also, even if they did and the IMEI listed on the handset is NOT blacklisted, as was possible with WinMo devices, you may have unintentionally changed the recorded IMEI on the handset to one that IS blacklisted - unlikely though I'll admit.

the sd card should not have anything to do with radio.

try to go down the bottom and press the "turn radio off" button
then when its turned off try to turn it back on, then see what happens.

Just done it and no changes.
Did it several times between reflashes too... not so much as a flicker...

No idea then, unless the IMEI has been blacklisted.

Ok.... thanks anyway.

Any luck getting this to work? Am in the same situation - t-Mobile unlocked Desire with a 3 SIM?
Edit: I have intermittent reception/connection to 3 now - I did a lot of recovering/trying RUUs which would partially load on Win 7 then just disappear...assume they should have done something more than that. What seems to have helped - and I partially had this problem in my Nokia E65 - was to place a piece of paper (SIM sized) behind the SIM to 'push' it onto the contacts. Well, maybe it was a software issus but it's now my luck paper and I'm not removing it!

Gone again. Very annoying.
RUU'd to RUU_Bravo_Froyo_HTC_WWE_2.29.405.5_Radio_32.49.00.32U_5.11.05.27_release_159811_signed (unbranded 2.2) and still no luck.
Any ideas?

Data and reception problem

Hello dear friends,
My Samsung captivate glide stopped receiving 3g data (mobile network not available).
Two weeks ago I had flashed Osimood ROM, all worked correctly until now.
Now I have only the wifi connection working but the Mobile network is not available at all (I cannot even call the emeregncy numbers - it gives me the "the process com.android.phone has stopped..." ).
I tried access the Settings-wireless and network-Mobile networks and it shows me "Insert SIM card".
Then I tried *#SIMLOCK# to check if my fphone is locked, it shows me "the process com.android.phone has stopped unexpectedly".
I tried to restore the phone from other backups from other Roms , but the problem is still the same.
Please help me to solve the problem and fix my phone.

#1 Thing can you make Phone calls?
#2 Verify your APN settings for Data? Is that Fine?

Try turning off your phone and re-seating the Sim card (only do this when phone is off) Then try turning on phone and seeing if you can make calls again if it still does not work try your Sim on another phone or another Sim on your phone. If unlocked any providers should work if not try from same provider.
I once had this happen to me for some reason my Sim was not properly seated. hopefully that is all that is wrong here as well. If your Sim is not being recognized, it may be hardware. Unfortunately and some people have stated issues where there Sim was not being recognized as they removed and inserted it in the past with the phone on, which could have caused some short.

Thank you dudejb for the quick answer.
I tried to re-seating the Sim card (while phone is off),
Tried to insert another Sim of other providers,
These methods didn't resolve the issue.
I never touched the Sim card before, so I think it cannot be the hardware issue.
Any another suggestions???

You could try clearing data for Phone and Phone Data (via Settings -> Apps), but I suspect that may not be good enough. If that doesn't work, use your installed recovery to wipe data. (Note, this will delete all user data on the device and reset your ROM to first-boot state!)
If it STILL doesn't work, use Kies to restore the device back to stock (Tools -> Firmware Upgrade and Initialization). If your radio works now, there was something wrong with the ROM you had, or your baseband got corrupted somehow. You can try your ROM again if you want; if the problem coems back, try a newer version or a different ROM.
If it STILL doesn't work, you're gonna have to call Samsung support. With the device in stock state they should be willing to help.

Thank you dudejb and roothorick for time and answers.
I resolve the issue by pulling out the battery and Sim card, after blow it by compressed air (dust cleaner).
My phone is back and it works like a charm

Makes sense and thank goodness (is that even a word?) Dust blocking connection to the Sim, interesting that it can do that. Glad to see it is working again.

[Q] No Network Access on Galaxy Note 2 ATT

Hello my name is Stanley, I recently bought a Galaxy Note 2, I'm from the Dominican Republic so I'm using Claro Dominicana, which uses the same baseband as AT&T, basically instead of the signal bar, I get a circle with a straight line on it, I don't have data, I can't make calls, I can't send sms, when I try to call I get no network access message, I believe it does recognize sim because I don't get any type of error when my cellphone boots up, when I bought this cellphone it wasn't rooted, so I decided to root it and flash a rom, I'm having same issues.
Can you guys help me out please? I already have my APN information but it's not helping, I've tried flashing roms and it's not helping, I really don't know what to do, when I first bought it, I tried my sim out and it did have internet, I decided to do a factory reset through settings menu and after that I haven't been able to get any type of signal, I would deeply appreciate your help guys, I'm getting kind of desperate here.

No signal bars means no modem or a sim card for a dead account. Did you pay for any airtime?

Did you try the free network unlock?
Might just not be unlocked

I did try it, I'm pretty sure is unlocked because it was just working before factory reset, I guess I can try to do it again, but I'm pretty sure is unlocked.

I tried several roms and modems and nothing worked, the last thing I did was going back to stock through Odin, but I still get same circle with the line on it, a stop sign, right now I'm on 4.1.1 stock..

i don't know if this might be an issues or not, but check your IMEI. T-Mobile webpage has a method to confirm if it been blocked or not.
http://www.t-mobile.com
As of August 8th of 2013, they've re-designed their webpage.
http://www.t-mobile.com/bring-your-own-phone.html
following that link, scroll down until you see this: "Don’t see your device?" and under that, a search box. click on the link below that search box. it'll bring up a screen within the webpage. input the IMEI from your phone (*#06#) and avoid adding "/ ##" as those aren't part of the IMEI. If it report as stolen, chances are, they probably blocked it. If not, then maybe your provider doesn't support the phone itself. you might have to call customer service from your area.

I couldn't find information about my imei using that webpage, it wasn't able to locate it, I used this webpage which said is clean http://swappa.com/esn I don't know if that page is good, but it says it's clean and ready for activation.

Try a friends sim card to rule that out

If the phone worked on your network before you rooted and flashed the new rom, then I imagine you must have flashed an incompatible modem. If you flashed stock back via Odin and that didn't fix it, I'm scratching my head. Try stock again. Then remove and insert the sim or toggle airplane mode. If it worked before, stock should fix it.

Hello guys, in this case it was actually a hardware problem it seems that the internal antenna of the cellphone which receives the network signal was damaged, I'm already getting it replaced, I'll let you guys know the results.

Do you know what was damaged. Is it the wire connecting the USB flex or is it the antenna built into the back housing?
