Signal stop working! :(

I woke up this morning and the signal was good and strong. Then at 10 am there was no signal on the phone. Tried to get a signal outside and no luck. I called T-mobile but they don't really know what is going on. I tried flashing another radio to see if it was the radio and still same problem. Hmmm what could be the problem I am in New York. Any one else experiencing a signal problem? Or if anyone had this problem before and fixed it. Any help is appreciated.

You aren't getting anything? No 3G, Edge or just regular?

Nothing no 3G no Edge nor phone works its stays on searching

hard reset doesn't work either?

Nope ^^ tried removing battery, hard reset, changing radios, and manually choosing carrier... I will try the sim card in another phone to see if its the phone

Call tech support back they told my brother they have had several of these calls but no one called them back after they told them to go change their sim card.
We tried the SIM card in another phone and same thing-no signal. So he went to T-mobile store and was issued a new SIM. Still no signal. In my brother's case it has to be an account problem so your best bet is to start there. Maybe try a SIM from another account, even one from ATT should work.

Got it working Thank you all for the advice. Apparently it was a sim card problem. I got a new sim card and I am up and running ^^

[Q] [HD2] Antenna exclamation mark and 'SIM card is missing' issues

Hello all, I bought a used HD2 off CL (USA), hoping to unlock it (if locked) and use it with my ATT prepaid sim.
Outwardly, the phone looks fine and everything about it works quite nicely, EXCEPT that when I insert my SIM card and start the phone, it shows me an exclamation mark on the antenna icon. When I disable all wireless connections and then re-enable it, the icon now changes to the SIM card icon with an 'x' next to it, and I am shown a screen with a keypad and the following message: 'The SIM card is missing. You can still make emergency calls if your service provider supports it.'
Thinking it was a ROM issue, I successfully loaded the latest ROM from [showthread.php?t=789506] but it did not resolve the issue. There is no issue with the SIM because it works nicely with my AT&T Samsung a607. There are no signal strength issues either.
Please help!

Can someone please provide some insight on my situation? I hope I haven't posted in the wrong forum; if so, mods may move it to the appropriate place.
Any advice on diagnosing the issue will be appreciated; I don't even know why the phone is acting the way it is. Many thanks!

Wait a moment, so your device isnt already SIM unlocked? Sounds to me like you need to go ahead and get an unlock code for it, then navigate to the \Windows folder and hit up the program called "simlock.exe" and input your unlock code, then try your ATT SIM again.

Thanks much for the reply. Other phones usually prompt for a SIM unlock code by themselves... why doesn't this one?
Running simlock.exe from Windows does give me the message "Network is locked, please input unlock code". Before I buy the code, I want to make sure that there's nothing physically wrong with the phone. It should give me at least *some* sign that my SIM is being recognized, but rejected due to network-locking, no?
Thanks again!

See thats the thing. With a foreign SIM card in the device, IF LOCKED, simlock.exe should run automatically on startup and ask for the code....so honestly I do not know if your device is messed up somehow, or if its just being wonky for the sake of being wonky. Perhaps you might want to flash a new Radio ROM and see if it then recognizes your SIM. BE SURE to NOT flash one with .51 in its name.

Thanks again. Can you point to a thread with detailed instructions for flashing a new radio ROM for my device? I found many threads while searching and I am confused. I don't want to choose the wrong instructions and brick this device; I haven't done anything of this sort before.

Look at the top of these forums for a stickie by Snarksneeze that will teach you everything you need to know.

Hi again... I don't have a spare 8GB MicroSD card lying around. Is there any way I can do this flashing over USB? I did read that there's a risk associated with flashing over USB (cable yanks, power loss, etc.) but I did flash the newest ROM without any issue, and hopefully I can do the same for the new Radio ROM.
The Radio version shown in the 'About Phone' section is 2.14.50.04, btw.

You can use your 16GB that came with the phone, or any other one for that matter. That requirement is more of a recomendation really. I have flashed with my stock 16GB many times. And yes, you can do it via USB aswell.

OK, so I have more information about the problem. I got the phone unlocked (I heartily recommend 'fastunlocker' on eBay) thinking that it would solve the issue... but it didn't. But, on a lark, I tried my friend's post-paid T-Mobile SIM in the HD2 and it worked! My AT&T pre-paid SIM does not... can this be a problem? The damn thing works nicely in other (unlocked) phones.
Is anyone else successfully using a AT&T GoPhone (prepaid) SIM on a TMOUS HTC HD2?

It may very well be the problem then. I have heard that some phones are incompatible with pre-paid SIMs.

God, that would suck donkeyballs. Can someone confirm that an unlocked TMOUS HD2 does not work with AT&T GoPhone prepaid SIMs?

had this same exact issue and realized that one of the pins in the sim card reader was stuck in the down position. I poked it with a small screwdriver and it popped back into place. works like a charm now.

Thanks for the reply. Are you sure this is the issue? As I mentioned in a previous post in this thread, my friend's T-Mobile SIM works nicely with the phone.
EDIT: Also, are you using it with an AT&T GoPhone SIM?

Bump... anyone?

Final bump: maybe I am SOL. :'(

Give it some time. Sometimes threads at XDA stay dormant for months and then suddenly BAM! a breakthrough happens.

I would say its your sim. How old is it?
I had the exact same problem. I bought a HD2 off cl and put my sim in and got the no sim message and exclamation point. I was using a sim from the voicesteam days but guess what it worked just fine in the Nexus one I had just gotten so I figured it had to be the phone. I finally used a friends sim and it worked fine. So I would turn the phone off in settings then slip his sim out with the battery still in and put my sim in and turn the phone back on. Guess what, it would work for about 10 min then it would suddenly go back to no sim message. So I went and got a new sim from T-Mobile and walla works like a charm. So try what I did and if you end up with the same problem try a new sim from AT&T. I don't know what is different about the HD2 but there something about the older sims that it doesn't like.
Hope that helps!

Hey... thanks for ther reply! My SIM is brand new (about two weeks old). I will however go to the AT&T store and get it replaced to see if it fixes the problem. Thanks again, I appreciate it.

Dear look my problem...

[Q] Please help me, I'm having problems

Hello evreyone.
I'm having a bit of a problem with my Samsung Omia II I8000.
I just got it from a friend of mine, and for 24 days or so it has been working great!
Really loved the phone untill the next thing happened:
I was playing a game on it, and I suddenley saw my phone didn't have connection with my provider. (Vodafone NL)
From that moment I thought it was strange, so I did a soft reset.
Nothing happend, still no connection, I did a hard reset.
Again, nothing happend, then I did a clean reset, and as you can guess... Still no connection.
I don't know if this sound fammiliar to you, but can you guys please help a man out?
Last thing i'm waiting for is buying a new phone.
Also the other things I tried:
-Opened the case, looking for the antenna wire, but it was still attached.
-Looked for a firmware update by looking at new pc studio, but it had the latest installed.
And somthing diffrent that might help you out, my wifi is working great, I don't now if that matters or not, but just to let you know..
Again: I REALLY,REALLY hope you guys can help me out!
Greetings, Olav

Have you tried either your sim card in a another phone to rule out the fact that your sim card is dead. And also have you tried another sim card in your phone just to verify that its not the sim card?
I will do these two things first before proceeding to do anything else.
I had a similar issue with my phone and was able to solve it by changing the sim card.

[q] invalid sim error

Ok so since nobody wishes to answer in direct rom forums, I'm going to ask my question here. I was very successful with Android as that's easy. Installing WP7 was also a breeze and the whole unlock thing cool. Problem is no matter what WP7 rom I try I always have an "Invalid Sim" error emergency call only. I am in canada with my provider being WIND mobile. Am I correct in saying that windmobile sims just dont work with windows mobile? or is anyone else having the same issue or is there a fix for this. All i am asking for is a simple "proper" response without the flaming. I've searched. I'm not new to xda but i am new to wp7. thank you
WOW Ok..

Can you borrow a different carriers SIM (from friends / family / colleagues) to test with, see if that works? That would help to understand if it is your SIM or the install of WP7. TBH it does sound like it is the SIM that is at issue.
edit: I just checked and the HTC connection setup app (from the market) does list both Canada and WIND, try it

Hey first of all thanks for a response. I'm also thinking it's not the sim (i'll try my wife's rogers sim card when she gets in from work.) because it works perfect with winmo 6.5 and Android without issue. I tried 3 WP7 roms and none worked with the sim..which boggles me
OK so after using my wife's rogers sim card it worked perfectly so it IS the wind mobile card that is not compatible with wp7. I guess i need to find a way to make it compatible if there is one.

I've gotten sim errors on my real hd7. To fix it, I have pulled the battery and reseated the sim. You might try to get a new sim from your carrier, just tell them your old one is acting up.

Tried that a few times and figure it may just be my SIM period although it's strange that it works without error with the android roms. But yeah imma go into Wind and grab a replacement and see how that goes

Did a new SIM help you, or did you do anything else?
After I have entered my PIN my sim is working fine, but after some time it says Invalid SIM.
/Regards Lars

I think it's an issue with the Roms. I think there are a lot of people getting the invalid sim error. I use the BlackSideSeven rom and I've seen several posts about it in the thread. There are also several other threads started about possible fixes and stuff.
Here's a link.
The easiest way to resolve is to turn on airplane mode and then switch it off. It doesn't stop it from happening, but at least you don't need to reboot.

Error in Android as well
I am having the same problem with MDJ Froyo 2.2. When I reboot into winmo 6.5 great signal all fine. I did notice that the simm card did move in the slot possibly bad connection. Now that I reseated the Simm all is fine. I also just read about antenna issue with the HD2 going to open and fix it to see if that helps.

S8 Unregistered simissue

Hi all,first time post.
I recently bought a new to me s8. Out of the blue I got an unregistered sim issue. I have gone through everything I can think of. Phone comes up as clean and not blacklisted. Account is active. Sim card works in another phone just fine. Other sim cards tested in other phones, donèt work in s8. Have swapped tray, have another s8. Reset, carrier info, full reset, manually set carrier. Just wondering if anyone has any other ideas I can try out.
Thanks

Really sounds like a black list. Check the original carrier. Not websites. Sometimes the websites don't update quick. Versus carrier who can instantly black list. Its either that or a bad Sim slot from the sounds
