[Q] Problem with mobile network on my device - Galaxy Grand Duos i9082 Q&A, Help & Troubleshootin

Hi all, there is perhaps a response to this issue but my English is not very good since I'm Cuban, so sorry.
I have a GT-i9082L which sent me to Mexico and worked perfectly there, to get to Cuba no longer worked the mobile network, I thought that maybe should unlock it, bring it to a technician and he said that there was no problem to unlock it was the mobile.
I gave myself the task of making root and install your latest firmware for samsung perfect, but the phone still does not work just the mobile network, update the modem and still the same. I also installed other rom and nothing.
Without inserting any sim under 112 or 911 and pretends that this marking but no sound. if I insert a sim tells me that the network is not available.
I tried with other sim and does exactly the same.
No if glitch or software, does anyone h presented this problem?
Another curious fact is that even without wearing a sim gets in some places all signal lines.
appreciate any help.
thank you

[Q] No service after unlocking. How to fix?

Hi, this is my first post.
Well, the problem I'm having is that I had been using my Htc slide with T-mobile and it worked just fine. Yesterday I unlocked it via IMEI to start using it with Claro -Puerto Rico-, so I switched to the Claro SIM card and it has no signal and it shows the (No Service) message, when the phone starts up it gets 2 white signal bars and quickly drops to no service, I checked the APN, the antenna, changing ROMs, set the band to GSM only, I've searched all over the net for solutions and nothing seems to work. :/ Then I switched back to the T-mobile SIM and I have no service either, so it seems as if unlocking it messed up the signal completely and it has rendered the phone useless.
Any ideas on what can be happening or how to solve this?
Thanks.

I believe it needs a hardware SIM unlock. This can only be done using a hardware device such as the XTC Clip, but I could be wrong. *shrug*

[Q] Sim card or Phone problem ??

Hi everybody,
I have a big problem with my phone (or with my sim card).
Since 2 days, and without touching anything, my phone has a lot of difficulty to connect the Network that I'm registered to (Orange).
I'd got some connection problems like these ones :
- "Your sim card doesn't allow you to connect this network"
- When activating the 3G it stays on "activating" (even if I reboot the system and pull out the battery for few seconds)
- Non-send messages
So I decided to wipe all data and reinstall. It worked…but…the next day it restarts..!!
Do you think it's caused by an app or by rooting the phone with xtc-clip ?
My specs :
- S-OFF
- Rooted
- RUU_Marvel_S_HTC_Europe_2.13.401.2_Radio_47.23a.35.3035H_7.53.39.03M_release_225747_signed.exe
PS : the RUU has been installed with the sim card inside the phone of course.
Installing ruu with sim in shouldn't be a problem.
Easiest thing would be try another sim before deciding what to do next mate.
Thanks for replying.
In fact my phone network works again since I've created the topic but I don't know at all how ..
I've tried my girlfriend's SIM yesterday but it is a blackberry one and I don't why my phone doesn't accept it to register .. I will try again or use a friend SIM this week end.
BTW does your 3g connection make about 5sec to be activated ? Before the problem appears in 1/2 sec I've got the 3g. Now it's more, but it works.
This is not an APN problem 'cause they're all OK and for messages it's not a problem from message center since it's OK.
So I am always wondering how the phone could have this behavior without any changes.
If it makes the same again, I will call my operator to know more about it and will make a feedback here.
It could well be network/operator related maybe they have a problem.
Anyway main thing is your back up and working again.
The problem isn't resolved unhopefully... It doesn't work at home .. Sometimes yes, and the rest of the time no network (even if I got all the bars of the network and the Edge Logo) and I can't do anything.
I called the operator yesterday, they say my SIM card was defective so I went to the operator's shop and they changed the SIM card.
But back at home, it doesn't work again .. And now I'm at my job's office and it works again ..
So I conclude that there is a network problem in my block of flats ?
I will call back them tonight to see what they tell to me and will make a feedback here.
Also I tried to swap phone, the same problem with my old Sony Ericsson.
I put my SIM in my girlfriend's Blackberry (network used to work for her), and it does'nt work. Then when she puts back her SIM card, she had no network as me...
So could it be a hack of SIM card to prevent you having network at home ? (it could seem a lil bit paranoiac I know ^^)

I don't think so mate.
More probable is that the mast that provides data that is closest to your home is at fault.
I would just make sure to report it and I'm sure others will have issues, so your provider should investigate and provide a solution.

I called the network provider, they say they will call me tomorrow for me to talk with a technician.
BTW my girlfriend called them earlier and they say this is a problem due to the residence.
I tried to ask them if there is a problem with the mast, they said it seems to be normal and network works well in my area...
But the network is fine out.. In the appartment it works about 10/15mins per hour ...
For the "SIM Hack" suggestion I told you, do you think this is possible ? (I doubt because no problem out ..)
Let's wait and see ! If you have any suggestions, don't hesitate !
Thanks for the support though !
Edit : always all the bars of network and E logo just sending, not receiving when it doesn't work.
Maybe your building is a blackspot meaning signal is not passing through happens to me indoors with wifi.
And where I live in a small village I can't get a good data signal indoors.
I have to turn off 3g altogether and opt for 2g only as it gives me better call signal.
But if I walk for 10 mins towards town I can switch to 3g and its perfect.
I would just wait to speak to the tech guys and see what they say.
Oh and forgot to mention my operator reduced my monthly bill due to my poor signal, haha.
Good luck hope they sort it for you.
If not try a different network sim just as a test.
The strange fact is that it used to work perfect in the building.
There are problems for about 4 days now.
When I forced 3G using "WCDMA only", it seems the signal was better and not blocked on E/G.
And now I turned it back to Auto and it works .. I don't understand what the **** is happening... !! It comes back to 3G/H.. but sometimes it fails again ..
I will wait for the tech guys, and if it's not solvable I guess I would ask for a commercial act such as yours !
Moreover this week, friends will come so we will see if they've got network (I believe they're at the same network provider, no luck ^^) .. !
Thanks for your support again mate, really appreciated !
My phone just started doing the same thing. Its a stock phone.
Finally nobody called me back but the network came back so no more problem now.. How ?? I simply don't know .. Good job "Orange".. !
Thanks for support though

[Q] Note 2 no WIFI with SIM card in!

Hi to all, I just receive a N7100. Everything is working fine is factory unlocked but when I insert the SIM card from (CUBACEL) the WIFI stops working. How can I solve that? Thanx in advance
Try another sim
Best regards
Sifou
Using a Samsung N7100
I have been using that SIM card on iPhones of all generations, Samsungs of many kinds, Xperias, you name it. Never got any issue but ok I´ll try just to make sure...And no, same problem with diferent SIM (from the same company though)
Funny thing I tried with one from Orange and WIFI is working ok. Anyone knows what is causing this?
This **** happen sometimes, but i don't remember what causing it, whether it's the radio firmware or something else
Try to read in other forums like the S3, this problem is well known and you may get an answer.
If you do have an update, do it.
Best regards

There is a wifi issue forum.
I am not sure if it's related to your problem but have a look.
Sent from my GT-N7100 using xda app-developers app
same problem with wifi on cubacel sim card
I also have the same problem with no wifi after inserted cubacel sim card.
I had tried to my first SGH-I317 (from Canada) and the 2nd SGH-T 889 (from T-mobile US). both even cannot scan any wifi after I inserted cubacel. But after I insert an UK number and reset the phone, it works fine. the redicilous this is, after I change again with cubacel sim card, the wifi signal suddently dissapear.
I also have a lenovo android phone that I bought in Indonesia, it works fine with wifi on cubacel simcard.
Something wierd in this case..
I hope anyone have solution

Hey newmucha,
Here is a xda-developers thread that gives you a possible solution to your problem:
http://forum.xda-developers.com/showthread.php?p=21406675
I installed the app, turned off wifi power saving mode in *#0011# and after that never had the same problem again. It seems that certain providers, CUBACEL in my case, have their SIM cards country code wrongly configured and this causes the wifi to crash.
Hope this helps!
Hi i have the same issue of wifi not working on local sim (Pakistan) and this software Wififix manager works on ICS only... I have At&t HTC ONE X + does anyone have any idea which software to use on JB 4.1.1? BTW i m rooted and using ViperXL 2.0.0 Rom.

DINC2 unlocked but doesn't recognize SIM in Panama...help!!!

hi. i just got this phone in the states before coming down to panama. it is verizon, but i called them and they gave me the code and now the phone is unlocked....but i can't get coverage here in panama. i've tried sim cards from a few of the local operators and none of them seem to work. i sure hope someone can help....here's what i've done so far: (oh, pls b patient, i'm a bit of a technophobe)
-unlocked sim. phone gives me sim lock is disabled message....that means i'm good to go, right/
-set phone to gsm only mode.
-software is androaid version 2.3.4
verizon global services told me that everything was as it should be and that the phone should work w/ a local sim card so i'm not really sure where to turn to......hopefully someone here can help. verizon also told me that the phone should work on the frequencies here. i have a claro sim card, but have also tried movistar, digicel, and masmovil. i was told that they use either 850 or 1900.
so, i'm totally stumped. hopefully i'm missing something stupid....btw, tried the sim in other phones (from europe and panama) and it worked w/ them. don't think it's a hadrware problem, but am i missing something? is there a setting change? do i need some kind of software update?
thanks!
update- get cell phone reception w/ gps on
don't know if this will help anyone get to the bottom of this issue, but i realized that when i have the gps on, i get full bar coverage. unfortunately, i can't leave the app on in the background. this makes me think it could be a hardware issue....bad antenna? anyone have any ideas
Same problem
I have the same issue as OP. Got my phone sim unlocked, and it runs on SenseMOD-2012-05-18-225643 Android 4.0.4.
For once I did a factory reset, skipped verizon activation (can´t do and won´t work because I´m not in the USA and do not have a verizon SIM or service), set my network preference to GSM/WCDMA, and the network wasn´t working.
Rebooted, my network is identified as soon as it starts, but then it goes to "No Service". Try to search for network but my carrier does not appear.
Any help?
EDIT:
Playing around with the phone, setting GSM as your network and restarting the phone let me make phone calls. No internet though and the APN was configured correctly. The "E" symbol for the internet blinked once in a while, but never got service.
Also, playing around some more, got my phone to not recognize the network again by removing the SIM another time. This sucks.

can't find signal

hello everyone
so i've recently bought lg g3 phone model LGLS990
everything works just fine until i go into mobile networks and change the preferred network to LTE
when i do that i lose my phone signal and all i can do is emergency calling, it's like there is no sim card inserted anymore
and when that happens i can't even change the preferred network to gsm again
but before i've done that i could've used phone for calling and messaging and internet but internet wastes my credit tho i've got a data plan and it's way too slow
i think this is related to my threat each time i turn on the phone a dialog box appears says: "hands free activation contacting network"
a couple of seconds then it fails and there is an option that says activate when ever i click it, it tries to reach my mobile network provider i suppose but then it fails too showing this message: "Sorry - we experienced a system problem during your task. please dial *2 from your Sprint phone or call Customer Care at 1-888-211-4727 from another phone to complete your task."
**im pretty sure that the sim is okay since i use it on my old galaxy s3 phone and i use 3g just fine
**i've tried to change the preferred network to all of the options listed
**i bought it new but the seal wasn't on the box tho it couldn't be used i guess since the screen sticker was on it
**the one i bought it from have brought it from another country but it's not shown that the phone is locked, i've never used a phone with a locked sim so i really don't know how is it like :/
**when ever i open sim toolkit i find the network provider's name there but when i click on it it keeps loading and nothing happens
**the android version is kitkat 4.4.2
sorry for any language mistake and sorry for my modest knowledge
please reply asap so i can try to contact the guy i bought the device from and try to get back my money if it's unsolvable issue
thanks in advance
