[Q] Unable to connect to mobile networks - AT&T Samsung Galaxy S 5

Hey, bought an S5 from China. Turned out to be the SM 900A. I'm in the UK, it worked when I got it, so thought nothing of it.
Two weeks later, it stops being able to connect to any network, with any SIM card I try. It detects networks but is unable to connect to any of them.
Have looked online and things suggest it is region locked... how can I test if this is the case? More importantly, how can I get it unlocked? What I don't understand is why it would work connect to UK networks for the first two weeks if it was region locked.
Cheers

anyone?

Galaxy-s not working 3g or gprs

Hello,
in Uk a brought a Galaxy-S (T-mobile) and unlocked it. Now I'm back in Italy and I put my old SIM card. The Phone works, except for 3g, edge or any mobile connectivity. I think there is two options:
- The phone is still locked.
- My sim is very old (from 1999), may be no more compatible with 3g.
How do I find out which is the case and how I solve that?
Thanks guys (girls too).
No network
Hi m8
Could you please check your imei number, I did exactly the same.
I bought my sgs on firmware 2.1 & unlocked it via free unlock tool, I then messed with some new firmwares. Recently tried to sell my phone as unlocked but when buyer put their sim in, It shows a signal but no data network connection.
After messing around with different sims i did a check & noticed my firmware is some stupid 04999????
Regards
Mark
What does that mean?? Is it related to IMEI somehow?? What should I check about it? How do I fix that? I've 2.2 by the way

Note I9220 no signal in UK problem

Hi All
I bought my galaxy note i9220 in China on 18th Aug. It is a genuine phone, NOT a clone just to note.
It was working perfectly fine when I was in China using a China Mobile SIM card.
Last Sunday I went to hongkong to catch a flight to London, and when I was in Hong kong, I changed back to my UK 3 SIM card, which again, was working OK in hongkong.
Before flight took off, I switched the phone off.
During the flight, I must have hit some button and accidently switched the phone on ( as when I landed, I took my phone out and it was “ON” with no signal).
Ever since I landed in Heathrow, I got no signals. The phone shows I can only make emergency calls.
I have tried all of the below but none worked:
1) Switching the phone off & on.
2) Take out battery (while phone was off) & SIM and put them back later.
3) Take out battery (while phone was on) & SIM and put them back later.
4) Reset to manufactory status.
When I go to Setting – Wireless & Network – Mobile Network – Search operator, I can see “3” in the list of operator, but when tried to connect to it, it said “Unable to connect to the network”.
The “3” sim worked fine in my old NOKIA phone so I don’t think it’s a problem on the SIM.
Anyone able to help? Thanks sooo much!
a suggestion..try to make sure you inserted the sim card with the bend angle facing the bottom of your phone..sometimes you insert your sim in a wrong way and this cause your problem..am not trying to be funny but it happen with quite a lot of people including me...
or Could be a fault on your phone..and these things happen..
or your sim is invalid for a reason..i suggest to get a pay as you go 3 uk sim card and try it ...or call 3 customer service and speak to one of their agents to have a look at your account ... they might send you another sim or pop in one of their stores and speak to someone about it...if nothing wrong with your account then am afraid it is a hardware issue with your phone..
Are you sure the phone is not a 4G phone?
This won't work in the UK as our Cell's are different as well.

Got my mum called the phone provider back in CHina they said it should be ok to use in the UK.
They asked me to check my SIM freuency (or sth like this). and said as long as it is on GSM900/1800/1900MHZ, then it should work...what is that???
Try change your network settings between the options, gsm, hspa, and wcdma. Think it's settings, more, mobile networks, network mode.
Probably one of those should sort you out.

Thanks.
When i went into the"mobile networks", the phone started auto search of network.
And it returns network lists:
3
O2 (forbidden)
Vodafone (forbidden)
I understand the 2 being forbidden as im not a custmer of either O2 or VDF, but it just does not allow me even to connect to 3..grrr very anooying.....
I will try changing the settings when i get home today.

[Q] no data connection

Hello.
Having problems with my I8190N. About 2-3 days a go it suddenly lost ability to connect into internet. I can switch data connection on or off, it doesnt make any difference. I have tried to reflash various ROMs and it's all the same, no internet. I get the usual signal bars but no H/G/E marks.
It did not happen after flashing, had CM11 on it for days and I could connect Internet just fine. No carrier limitations either, I can make calls out and same SIM in my old phone can go to internet.
Should I flash the stock ROM/bootloader back and RMA it? Or is there something else I can do? (perhaps known issue and solvable on my own)
Phone is fairly new, bought it in August as brand new.
i suppose APN settings are correct?
you can try to flash another baseband to try with it, what is yours current baseband?
basebands you can find here for N version, XXAMJ ist newest and working for me...
I had the same problem a couple of days ago. It turns out that my problem was the simcard, have you tried to put another simcard in your phone and see if it works?
I have this problem, same with two phones and two SIM cards, both phones are ZTE, both problem SIM cards are on Vodafone, both phones have no problem connecting to data via t mobile sim? This leads me to believe that voda data does not work on zte phones, apn details are correct. Does anyone knowa fix?
finally sorted it........... f'd around with a few different apn's and even phoned up talktalk(same as vodafone network) who confirmed I had the right settings which I hadnt!
Found the correct settings on the geeksquad website. seems i didnt need to bother filling out some of the fields and then wham internet connection straight away!
Sent from my ZTE V967S using xda app-developers app

Network Unlocked LG Optimus 4x HD Cant Connect to New Network

Hello everyone,
I have just recently unlocked my phone because I'm currently away for business in China. However, when i got here and got a new simcard with the local mobile stores my phone cant connect to the networks at all. my phone is rooted and i am quiet a beginner regarding cellphones and what not. any help at all is greatly appreciated
Go to Settings / Mobile / Preferred Network Type.. choose different settings? Maybe you are trying to connect to a frequency that is not offered in China... or click "Choose Network Operator"
yep i did that, theres a choice of three networks, all three for China, two is GSM and one is UTMS, i tried connecting to any of the three and was not successful. automatic select network was also not successful. I bought my phone with Wind
Try inserting that sim card in another phone.Couple months ago i just lost signal with my phone was busting hed for 2 hours try to fix it and eventualy i realized my sim card was dead.
thanks for that, i have my old wind simcard and that works fine I dont think its the simcard's fault because i can still choose to select a network without the simcard in my phone, which still doesnt work.. pretty frustrating.
I was reading something about a HTC phone having the same problem and they solved it using something called a superCID or something like that. Does that ring a bell for anyone?

So you bought phone from Wind, wind simcard works. You put another simcard and it doesn't work?
Your phone is locked to wind. So it won't accept any other simcard aside from wind simcard.

Help with Network signal

hi guys, buy an s8 from TMobile on Ebay. Upon arriving in my country (Honduras). buy the network unlock on Ebay via remote USB (SAMKEY). at the beginning everything working but after a few days the phone shows "only emergency call".
Since then in some days it recognizes a signal and others do not.
The phone is not blacklisted in my country but it financed in the USA (TMobile blacklist).
Does anyone know what could be if it is software error or hardware error?
Thanks Guys!
