[Q] HD3 no signal!!~~ :(

I bought my hd3 in china .it was unlocked, originally sold to hongkong.
after I went back to the U.S. I kept using my chinese sim card, and everything worked fine. when 7720 released ( it was a long time ago) , I swiped my cell phone, and from then on, my hd3 always tells me that 'no network found'. I tried to search network manually, and I see att and tmobile, but cannot register. now the signal icon has an empty set symbol,...and I don't know what's wrong???
p.s. my att sim card works well on my hd3...I've tried different roms, none of them helped.
the problem is solved, I inserted my chinese sim card into an android phone and it successfully registered in att, and then when i inserted it back onto my hd3, i got the signal LOL.. ..i've no idea why this happened, wish this may help to someone got the same prob.

Have your tried HTC Connection Setup?

yes,i've tried many times
it can detect the right carrier, but doesn't really help

Sounds like you may have to do a hard reset and then reinstall Setup Connection. During the configuration setup after the hard reset you can tell it what region/country you are in now; same for Setup Connection.

thanks for your advice, i just don't understand why should i hard reset the phone. as i tried many roms, each time i swiped in a new rom, the rom was brandly new, like a factory reset, and each time connection setup doesn't work.
i'll take your advice and see if this works out.
btw, i can't see your pic, it's too small. is it something relate to hard reset or ?

no, it doesn't work. T0T

You said your ATT sim works fine... why use the chinese one then? Also i think ATT will give you a new sim if you are under contract with them. You are paying for service aren't u?

Try to insert the sim card with the tablet on. Does it restart? If not are you sure you are inserting it with the correct side?

Hello, thanks for the answer, I tried all that already, anyway the Sim only fit in one position so you cannot take wrong.
The tab restarts when inserting card yes.
I tried also taking the battery out for 10 mins... Clean the head of the Sim compartment but no luck.

Just removed the back by pushing under the sd card slot then inserted a flat tool to unclip the lid, then removed the batery connector.
However i still have the issue, its driving me crazy as it is my working tool...

does the original SIM still work in it?
perhaps try flashing original & latest frimware updates for new/different modem.
I know one chinese version of tab plus has locked bootloaded dud to China's restrictions, I would not be surprised if they have locked down modem as well.
And for the heck of it you could always try Galaxy S Unlock app, to be certain you're unlocked.
Strongly suggest backing up /EFS folder (twice) just in case.

Thanks for the suggestion, I flashed the device twice already but there is only one file. Could you direct me to the files you are referring to please I'll take a look when I'm back home, thanks again.

I would try EVERYTHING else before flashing a new modem. Toggle airplane mode. disable/enable packet data, etc.
First, does the original SIM still work?
If so I would give the Galaxy S Unlock a shot for the heck of it.
These other SIMs have you tried them in other devices to either make sure they work or activate them?
did you purchase device on a SIM contract??

sim issue
The original sim does work, i have put it in other phones and it works fine, i have also tried other sim but still same issue, message still say "please insert sim card"
I have purchased the tab sim free in hk so no, no contract, it did work fine since december until 2 days ago where i input a data only sim card, when i insert sim card it does reboot, meaning it detects the card in the socket but thats it.
Concerning Galaxy S Unlock my tab is not rooted i have used only legit firmware until now so im not sure about that.
PS: looking at my phone servie status it says:
Service State: Out of service

Are you sure you havent been sold a bad or expired sim card?
Id try to give samsung customer support a call at least, they will probably tell you to send it to them anyway.
Can you try exchanging this for another one where you puchased it?

Well, i bought it during my holidays in hk but i live in norway, so... bit difficult to chage it, the sim card works just fine in other devices so it should work in tab.
I tried the galaxy s unlock and during step 1 it says error for efs backup, so either because im not rooted or because my efs is corrupted.

Probably because youre not rooted.
Im wondering if the SIM could be from a small provider which isnt recognized by the device?
It should at least dected then say something like network provider unrecognized, etc.
I really dont what to say.
I would keep trying other sims, try to get a 5$ pre pay from a major carrier like O2, 3, tmobile, etc. not sure what carriers you have over there.

Well i use Telenor which is the biggest and also quite big in europe, i will call customer service tomorrow and hear what they say, but i fear its gonna rip my pockets...

did you push the simcard all the way to the bottom of the slot?
I need a pen to push it....so I wonder if you insert your sim card properly.

yes, since the first time, repair shop said they cannot help since device has been purchased in hong kong...
No solutions until today...

Solved
After dismantling the tab completely (hard work guys...) i confirm that the sim card reader is defect, the cushions that reads the card did not press completely on it so i applied a temporary fix by adding an extra layer to thicken the card so it can press correctly on the cushions. I did try this fix before with the tablet in one piece, however i could not get it to work correctly.
Anyway thanks for your help and i'm happy that i can use it again

[HELP] Can't connect to any network in UK

Hello
I have problem with my Sensation.
I bought phone year ago (on polish equivalent of ebay), from someone who lives in UK and he send me it to Poland. It worked perfectly there, till now.
Two days ago I came to UK, and since I switched phone ON after getting off the plane, I can't connect to any of the cellular network.
I am sure that SIM slot is OK because phone asks me to enter SIM pin code.
When I am trying to manually select network I got 'Your SIM card does not allow a connection to this network', and when automatically 'Unable to connect to this network at this time. Please try again later.'
Wifi and GPS working fine.
I dont have a clue whats the reason of that, where the problem lies.
Phone has ARHD 6.7.2 ROM, firmware 3.33.401.106.
Any help is appreciated as I need phone badly, to have mail and internet access throught the day :crying:
PS. I am starting to think that UK seller could scam me, and sold me phone with blocked IMEI or something like this? :/

Hi have you tried to change your radio And ril? This could help you regain signal. I can't recommend a particular radio and ril because we live in different areas and it will be different. However you can start by experimenting with the generic ICS radios and rils and see of one of those will reconnect your signal.best wishes.Hope this helps solve your issue!

Sounds like your Polish carrier/SIM might not be allowing international roaming. Get a PAYG SIM for a couple of quid and try that. That'd prove the phone side of things.

Try
Try putting in a diffrent Sim card to see if it's that.

If your home network doesn't have an agreement with UK networks then your SIM won't work, not sure if this is realistic as I thought they were all only to happy to help others take money from us. Try a UK SIM, if that doesn't work then your IMEI is probably blocked in the UK, but not in Poland.

It's a simple answer Your phone has been reported as lost/stolen in UK and IMEI has been black listed. It's now paper weight in UK.
Pogon telefon w PL i kup sobie inny w UK.

Sorry for not mentioning - ofcourse I tried other sim cards, like o2 and vodafone - neither of it worked. My PL carrier sim worked in roaming in different phone.
So it looks like IMEI is blocked, I just wonder if I should go to the Police to check this out but I dont want to have it confiscated :/
Butif its true, Im not going to leave this scammer unpunished - I'll try legal action :/

Instead of legal action why not just find him and remove a thumd. maybe both thumbs to be sure.
The sad thing about having an IMEI number on the black list is that it can't come off that list. At least from my experiences.

Apart from it not being a paperweight. Revival is possible but ILLEGAL.

Which is why you shouldn't purchase a non compatible phone, for use in another area?

This is why you shouldn't buy this phone from the scalpers. The chinese version does not support many of the worldwide bands that the "global" version of the phone does. My advice would be to try to sell it to someone who can use it and sign up on the OnePlus forums and wait for an invite for the CM version which supports the bands you need.

Get a new sim, sounds like an old sim that doesn't have the updated CellID info in it.
I had to change my 3 sim when I had my SGS4 as it wouldn't register because it was too old.

I had that happen to me on the interational one and felt quite dumb afterwards...
Make sure the SIM card tray is rotated DOWN so that the contacts on the sim card look to the back of the phone.
It will fit both ways (imho a very strange design choice) but with a tiny little space left when rotated the wrong way.
In other words: turn the phone on it's screen before inserting the sim card facing you.
I have _NO_ clue why the phone thinks it has a SIM card when obviously it cannot access it...

Hey there. I have the same issue with Vodafone Sim card AUSTRALIA. phone just stopped working all of a sudden. Why would they blacklist it? Other sim cards work on the phone.

have you been able to resolve your issue? what was the fix?

Has anyone got any solution of this? It's been quite a long with this issue, I've searched a lot of topics but no solution.

I have the same problem. Phone don't see simcard somehow. Flashed latest original firmware works for 1 min. Pull out trace with sim insert it again works for 2 min and stops working. When it works for small amount of time i think IMEI its not blocked and almost sure its software issue. Yesterday flashed different roms and CSC and modems no luck. SimCard changed for new one. Have someone some clue what to do ? I can provide logs if needed.
After instaling Samsung Phone Info app from market gsm wen't back online. Probably a coincident but when I go to Hardware screen ther was no modem model. I tap it few times. Close apk run it again modem went show itself after a while GSM signal is back.
After reboot no signal again. Then i make magic with phone info apk again and signal want back.
This apo make some sort of device discovery and reset modem device / driver or this is pure luck.
