Hi folks, can anyone please help me with this problem?
My brother in law has asked me to look at his S740. He has tried several o2 SIM cards (UK) in this phone but always gets told there is no signal.
Not only that, but there is a symbol where the strength meter should be that isn't documented in the user guide.
He has also tried my o2 (3G) sim and a Vodafone sim, both UK.
Any advice gratefully recieved. We have tried several hard resets also.
Thanks
This means it's looking for signal. My guess: Still SIM-locked?

Not sure if it's SIM locked as there is a menu to select which carrier to use.
It reads the SIM correctly and sets it all up for o2, but just doesnt get any signal.
Does anyone know where the GSM antenna is on these? Maybe its a bad connection.
UPDATE:
I've had a mail back from HTC that recommends I send it in for repair, lol.
Now do I take it they are robbing buggers or do I take it that the icon is an indicator of a hardware fault??
Hmmmm, dilemma. lol
Are there any more suggestions on what it may be?
Has anyone successfully taken one of these apart?
it may be because of a hardware error...try to connect to a wifi network...if it impossible to find a wifi network then it is due to a harware problem.Most likely because the FR coaxial cable is out of its possision...download the service manual and see how to fix it.

Hi sasiskas, it conects fine to my wireless network at home. I take it from your response that the cable serves a double purpose.
I downloaded the service manual so I could take a look, but only got as far as removing the 4 screws at the back. lol, I couldn't figure out how to get it off, lol
I'm still stuck at the assumption that it is indeed SIM locked, and so will try to find a suitable card to try out.

Try contacting with your phone's provider (shop,e-bay seller whoever it is) and ask him details about the sim.Good luck.
hey

Thanks. I have tried the same but just keep getting a vender ID, (lol spelling), error.
I would appreciate any input whether you have success or not, it just may spark an idea off.
I cant get in touch with any sales or provider as it was gifted to my bro in law. He's not that bothered about it but would like to have it working if he can.
Thanks folks.
Hey! I think I know the solution to your problem...I had exactly the same problem when I hardReseted my phone.
Go to "Start-settings-Phone-Band Select"
and then select
1.Network type : Auto
2.Band Type : "Euro" if you live in Europe, "US" if you live in USA , or "Japan" if you live in Japan.
Good luck...Let us know if it worked!

Yes that is a good suggestion because the phone will display that icon if it can't find a *usable* network, be it that the SIM doesn't allow it or if the bands don't match the selection on the phone or the bands are not usable by the phone hardware etc.
I would suggest downloading & running HTC Field Test (fieldtest.exe) with & without a SIM installed, with each network & band setting & see if it shows any towers or signal. (Normally you want Auto for both but you may not have that option or you might prefer to set to a KNOWN working band to conserve battery & minimize searching) If should show something even without SIM or with SIM lock because it's supposed to support emergency calls either way. If it shows signals with SIM but you still have same no service icon then it's likely SIM locked (although the phone should alert you to that fact) so odds are the phone hardware, rom or settings do not support whatever signals are available to you. (Btw if field test shows N/A for all the values you need to app unlock your phone)
Hope that helps.
Bill
can you share a link with HTC Field Test?Thnx
Search is your friend.

Hey all I'm having a very similar problem.
Had my HTC for some months now but in the past few days I've found that my network signal is becoming very unpredictable.
I'm also on O2 and I used to have a pretty contstant H (I presume HSDPA) connection.
Howeever im finding now the phone with go from H to 3G to GPRS to E to no signal in the course of 5 mines and round and round again!
Its very annoying as it means I cant make / received calls or texts fluently and even cut me off on a phone call too.
However usually on phone calls it will keep me connected ok till I hang up and then go to no signal.
I've checked the wireless and it is picking up networks..
Any other suggestions? I will try the field test tomorrow...
PS I know its not the network as my work blackberry is O2 and is not having this issue..
Cheers in advance!
Well, just to close my input on this thread.
I tried various ROM's available from this site and none worked.
I did try the band selection settings but still a no go.
I did have limited success but overall, nothing. The phone has now gone back to the person who asked me to look into it and to my knowledge he is going to sell it to one of these phone reclaim companies.
I did check and one place, I think through the post office, is offering £80 ish so not bad I suppose.
Anyway, thank you to all who have made suggestions and wotnot. Personally I'm still happy with an old Nokia 6300 and my Wizard (Mini-S)
Thanks folks.
Please if you found solution reply here, but read at least first post before.
1. Does AT&T SIM reactivate WiFi, after other operator SIM used? - Yes (in my case), but you may need to reboot (soft) 2-3 times.
2. Does Motorola Update 1.57 solve the WiFi problem? - NOT IT DOES NOT.
3. Why part of unlocked phones have WiFi problem and others not? - Open question, as it is NOT a hardware failure, it is somehow related to unlocking process.
4. Is there any solution at all? - Honorable member crnkoj is developing the solution in this thread
IMHO WiFi related issue currently deserves sticky. Also it would be perfect to have one stop FAQ for WiFi related issues.
Im using an unlocked atrix n the wifi is working fine...
You in the lucky group. Mine is unlocked and none of the many potential solutions get me on wifi (short of tossing a broken sim in, which is a pain...)

1. Apparently people who have one, reported it reactivates wifi after a few reboots, otherwise you have to put in a broken sim and do a factory restore to get it to work
2. It does NOT (not the leaked 1.5.2, not the leaked 1.2.6 and not the prerelase 1.5.7)
3. i think it has something to do with a config file or an app that blocks it (altho im leaning toward a config file that gets from the carrier some info and not really blocks but more like a bug disables wifi, because of some conflict)
4. you can use your phone with sim card and 3g/4g data, while preinstalling everything before on wifi, or just use it a a small wifi only "tablet". I am unfortunately not that good with android/linux to figure it out on my own (i sort of got the phone into a boot loop 3 times now, trying to delete apps/ change config files in the /system dir). One of the forum/irc users is nice and tries helping me , but he doesnt have the phone himself so, hard thing ...
5. Hopefully the released source codes will help, doing a semi custom rom without the att bloatware, which could probably fix the issue.
What about the new update that was just released does that fix the problem?
It seems up to now there is no solution for wifi problem. Several reboots doesn't work for me. Please respond if someone was able to succeed.
BMW, maybe read the 2nd point of my above post, no update fixes it.

I thought the new update started with a 4 but now I figured it out sorry.
It was big buzz week ago on broken wifi on unlocked AT&T phones. Now I can't find even the thread on that. Did you people find solution?
I have upgraded to 1.57 and it is definitely not a solution.
I tried hard reset with non-working card and wifi on hardware level works perfect. As soon as I've put working SIM in, it stopped and even reversing to non-working sim doesn't help. hard resetting every time is not a solution.
Still waiting for final solution.
I unlocked my Atrix in Australia. I shall walk you though my steps to see if you can pick out anything specific. I was very worried about the WiFi issue so i took many precautions.
I bought the code from Cellunlock.net - using the android50 code to bring it to $20
in the meantime I used an old, inactive SIM in the phone and on boot I would just hit dismiss on the network unlock screen and run the phone on WiFi on my home wireless. (WPA2 key)
When my unlock code arrived (2 days) I went to the wireless settings, DELETED my wireless network from being saved.
TURNED OFF WiFi entirely
Turned phone off properly and replaced the SIM card with my active Vodafone AU SIM
on the network unlock screen, I used the first code out of the two they provided and it was accepted
went back and re-added my wifi network, and doneeee all is working well.. hope this helps someone somewhere.
Thanks a lot DarkRyoushii
Problem is that I received my Atrix already unlocked. I contacted Cellunlock.net if it is possible to unlock it second time, but they responded it is impossible.
What gives me hope, Motorola has to sell originally unlocked phones and their ROM should be free of this AT&T crap. So using that ROM supposedly will help.
I have an AT&T Atrix and the unlock code didn't adversely affect my Wifi. I've actually never had an Android that locked onto Wifi as well as my Atrix. It's tight as hell. Never, ever drops!!
I don't see the correlation between the two but maybe there is some weird quirk. Not denying anyone though. I just wonder what the heck Motorola did to the framework to cause that to happen. Weird.. hope it gets patched up too.
I hope this gets fixed soon. I have an atrix with the sim unlocked. I cant connect to wifi, and I cant get passed the motoblur to set debugging and root the phone. This is very frustrating. I'm in qatar so I dont have a att sim, nor do I have a broken sim either. I guess I have a $600 dollar paperweight.
mine is perfect

Don't put any sim in it at all then turn it on. You should be able to connect to wifi that way and get past the setup.
I don't have an atrix yet but I heard that this works. Goodluck.

Your wifi wont be fixed after you put a sim in but it should get you past the motoblur sign up.

Guys, if you have 3g (or in fact any) data available on your sim its not a problem. When the motoblur setup tips up, click the settings hard button (the one to the left) choose "configure apn" (or something similar), put in the data you get from your carrier and bam, you should be able to finish the setup.
Wargame1 I bought several sims at eBay and is planning to check with them. As soon as they work, I'll let you know and even send you one from Baghdad.
Wifi problem is not solved yet. When Motorola is going to start selling originally unlocked versions? Their rom should help.

just try it with mobile data man, youll be able to activate motoblur...
and erm, you probably wont be able to install the unlocked rom on the att atrix, sicne you cant change the att/bell roms on the phones either .... maybe just a /system reinstall, like the Gingerblur/Gladiatrix mods
Dear all,
I have a Legend with S-ON (1.01), and I used fake-flash to change ROMs. The mobile phone has been fine with a custom ROM for more than 3 months now.
Suddenly, 3 days ago, the phone rebooted while browsing settings and when it came back on, the device could not recognize the SIM card or connect to the network and get a signal.
The problem is weird because the device (a) can find networks if I search for them, (b) can make emergency calls, (c) connects normally to both wi-fi and the SIM 3G internet but does not:
- get signal (always zero lines)
- recognize the sim card (always asks me to rescan for new contacts, and the process fails)
I tried wiping everything, I tried reflashing, I tried flashing another ROM. The problem persists.
Would flashing a new RADIO potentially help? It is the only thing I have not tried.
I am really at a loss here. The device did not fall down, or had a knock or any other user damage. The problem started suddenly and i can'f find a way out of it.
Anyone who manages to find me a solution gets a paypal beer
PS: Something important is that the phone DOES know that SIM card is there, and DOES partially recognize it: I am asked to put my SIM card PIN, which is accepted correctly.
Hey
What I'd do:
1.)Try the SIM in another device - could be a SIM problem...
2.) As you are 1.01, there is no risk in Warranty repair, so unroot and send back to shop if the sim proves OK in another device..
Probably a stupid suggestion but i had at one point no service when my battery cover was not on...
When i was rooting mine, i kept the battery cover off because i was stuck so many times in the middle of running step 1... so never bothered putting the battery cover on...
after i succeeded in rooting, i still saw no service... but as soon as i put the battery cover on , i was able to pick up the network
@QkSi1ver: The Legend's antenna is located in the battery cover, which is why you would have had no reception with it removed.

Which could be the reason for the SIM problems : if it is not set correctly it can't communicate proper with the mobile , that's why it asks for searching for contacts ( I had a similar problem a few months ago )

i don´t believe it! first of all, thank u kindly for ending my nightmarish odyssey through expert forums across the globe!
that just did the trick, uber cool! and yet it sucks, because i wasted most of my sunday and half of today to solve this, wondering why nobody even mentioned connection probs.
maan, i´m tired, i´m going to bed!
So. I've had my S3 for quite awhile now currently on 3 network. Something really odd happened though.
I was able to use it normally in the morning, once I got to the afternoon it I lost all network.
The only thing that I can use to connect to anything is Wifi
Usually there would be a little "H" symbol next to my signal bar when it's full. Now there is nothing but the full signal bar.
When I pull the notification bar down I see a Emergency calls only though I have full signal
I've gone into Settings>More settings>Mobile networks>Network operators to see if I can find a way to connect. I can choose from the networks on screen. Yet it tells me Unable to connect. Try later. I select "Select automatically" which doesn't help either, as it tells me "Registered on network" WHAT NETWORK?!
The Network mode is on Auto
My Mobile Data is on.
My Apn is on "3 WAP"
I've tried rebooting the phone.
Restoring to factory settings.
Turning phone to Flight mode then off again.
Re-inserting Sim.
I've even rooted the phone to see if it would work!!
Can anyone help me solve this ridiculous puzzle? :crying:
Thank you for your time.
Mine is the same. On 3UK in Leicester

Last time I hd this issue, it was caused by a faulty SIM.
I think you have some really bad news. I looks like your efs folder is messed up.
you need send it back if in warranty.
otherwise you can get it repaired from some service centre. They will use SPT or some other repair tool to fix this issue.
You see full bars because you phone uses any available signals for SOS call.
Otherwise it will not lock to network.

Hi! since you are new here, have you read the Forum Rules? not that you've done something wrong but just to get you informed
Here are some suggestions i can give you
okay. if ONE fails, do TWO. if TWO fails, do THREE. if THREE fails, do FOUR.
ONE: reboot
TWO: try doing factory reset (don't forget to backup) / wiping caches
THREE: root your phone and flash another modem
FOUR: contact your network service provider about this matter
i hope this helps Cheers!
samsung galaxy s3 i9300 sim registers but only emergency calls
In my case (sgs3) the problem was caused by the fact that I also formatted the efs partition (something used by Samsung to store hardware identifiaction like IMEI, ...).
If efs is empty/gone/changed(?), the phone will be unable to make regular calls: only emergency calls will be available!
Peace!

But this efs issue has been answered many, many times in the forum - usually people wrecking their £500 phone because they didn't read or understand what they were doing.
This forum is messy enough without needlessly bumping long dead threads that didn't have anything of use in. If people want really helpful information they should read the all-in-one sticky in the general forum.

Ok you're right, everyone should read sticky notes and try keep the forum tidy. Look, I don't want to go too off-track here but this problem is not just limited to Samsung handsets. I'm seeing similar reports about Sony's, which is what i've got. And there is no efs partition that can be saved on a sony because they don't come with one. I'm beginning to suspect that the problem might be with ICS/JB and this is why it's poping up on different phones/threads, with different roms etc.

[Q] "Can't connect right now. Try again later." or equivalent in stock, CM9 and CM10
Hi folks! Needing some help, please.
I've googled my problem a lot but couldn't find any working solution. Below is the detailed history.
I have recently bought a Samsung Galaxy S3 GT-i9300, cut my previous SIM, and used it for about four weeks with no problems. During this time, I rooted my phone, backed up the stock ROM, installed CM9 and afterwards CM10.
About a week ago, while using CM10, I switched off airplane mode after about nine hours and the signal power meter was empty. All the services related to my carrier (SMS, 3G, calls) were inoperative. I rebooted the phone, tried removing and reinserting the SIM, with no success.
I tried flashing the previous backups, also with no success, but noticed that while using the stock rom, the signal meter was full. This prompted me to access "Settings > Wireless (...) > More... > Mobile Networks > Network Operators", where to my surprise all the available carriers were listed. I did the same check in the rural area of my town, where I know my carrier does not work, and the cellphone correctly detected only the other three carriers.
These symptoms led me to believe that my cut sim could be the problem. I got a microsim from my carrier, but the problem persisted.
After this, I assumed the problem was software related, googled it and found some recommendations:
Complete wipe and backup restoration: this was not successful with stock, CM9 and CM10.
Complete wipe and stock ROM re-installation with Odin: also not successful.
Modem flashing with Odin: also not successful.
Firmware flashing with KIES: I put the cellphone in download mode and made the firmware recovery procedure from KIES. Also not successful.
Restoration of efs folder and IMEI related issues: I did not have backup of this folder, but the symptoms related to the problem in the posts I found always included the absence of IMEI. When I type *#06# in my phone, I can correctly see my IMEI, so I discarded this possibility. My carrier also informed me that my IMEI is not blacklisted.
I thought of getting a new microsim to rule out any SIM related issues, but still haven't done it.
Information regarding my phone:
Phone model: GT-i9300
Baseband version: I9300UBLG2
Firmware vesion when on stock (from KIES): PDA:LJ1 / PHONE:LI2 / CSC:LJ2 (ZTO)
Could someone please help me? I still have not tried the EFS folder troubleshooting, but the procedures I found were related to problems that did not show the same symptoms as mine. Do anyone have any suggestion? Please tell me if any more information is needed.
Thanks!
Why not just get a micro Sim to begin with....they don't cost anything and it saves a whole lot of hassle. My guess is the sim reader is damaged....IF and WHEN you decide to get a new micro sim, if it doesn't work then that could be the only cause and the service centre your only option. Seriously dude, next time to save yourself hassle....go an get a micro sim from your carrier, I wouldn't even think about hacking away at an old sim because I can't be bothered to walk to a Vodafone shop.

I have just come back from the carrier store, where I got a new SIM, and the issue persists. I also double-checked any IMEI blocking or problems with my services, and everything is ok.
Coincidentally, a Samsung consultant was around. He checked my phone and talked to Samsung tech support describing the issue.
They do not think it is related to the cutting of the SIM card for two reasons, the first being the ability to locate the carriers, the second being the fact that a visual inspection of the slot and the scratch marks on the SIM card do not indicate a broken or bent contact.
Obviously, he recommended that I send my phone to an authorized Samsung service center for maintenance.
I am still inclined to think it is a software related issue. I will, of course, send my phone to Samsung if it is case, but in the meantime I would like to try new procedures to bring back my phone's ability to connect to my carrier.
Suggestions?
Thanks in advance!
An additional information:
I tried checking my sim through some apps, to confirm there is no damage in the contacts. GalaxSim Unlock is able to detect my sim and correctly show my phone status as unlocked.
Any suggestions on tests?

Hi!
I bought S939(not completely new), which from what I understand is not a device that's created for the European market. In order to make it function, I believe that the device was rooted\modified. Now, I can perfectly use it to go on the internet, make photos ecc, but when I put my SIM , I'm unable to "catch" the network of my provider. A message "Can't connect right now. Try again later." appears. I can save numbers on the SIM, for example, but unable to register on the network.
Also on the main screen, I can see writter "Invalid IMEI".
Thanks!
