Signal Issues-Common problem? - Galaxy S II Q&A, Help & Troubleshooting

I need to change my HTC Desire and I am thinking of a Galaxy SII. I will buy it used as I am not in the mood of spending much so as I was looking the ads I found several ads stating about faulty phones with a signal issue. Is this a common problem for the phone? What should I look for before I buy one?
Additionally I have another question. I am in the UK, these phones here come unlocked for any network? If not, flashing them with custom roms or firmwares can unlock them?

Phones in the UK are either network locked or unlocked dependent upon vendor check before you buy .
If not, flashing them with custom roms or firmwares can unlock them?
NO custom roms do not unlock see the unlock posts .

Galaxy s2 dosent have any signal issues for the majority of the users. If you feel your signal is poor, you can try flashing different modems and keep whichever you feel good.

HI people...plz plz help!!

Hi people,
Is there an Atrix 4G global version also?
I just ordered an Atrix 4G phone in India through a local, popular newspaper ad by the newspaper's online shop. But now I have several concerns about the same. One of them being, is there even a global version of the Atrix 4G? What if this phone is a rejected device, GSM SIM locked?? Have many other questions, but they are software related...but this is my primary concern..
Can anyone help...
Thanx!
I only think that GSM SIM lock you always can unlock for money through internet. there are many sites with this service.
but if you want to change roms to custom you cann't buy phone from Spanish or Chinese, because you will receive a brick.

[Q] question U.S. sim version

Hey everyone, rare poster frequent lurker...
I seen a few people posting about reviews of the us models so I'm hopeing this is a question that maybe able to answered now?
Does anyone know if at&t and tmobile versions of the phone are one in the same? I mean i know they both use different frequencies for there 4G/LTE / + network but is Samsung installing radios/modems to cover both in the gsm model?
Here is my question in use.. I am interested in the tmobile s3, I have a work phone that is on at&t. I would like to run dual sim so I can just carry one phone or worst case swap sims as needed. Is this possible or would carrier specific models prevent me from accessing high speed internet?
I know its early yet but like I said I know there have been some hands on reports and a lot of talented people here that might know just from knowing the hardware Samsung used? If anyone can shed some light it would really help me out as I am doing my research now on which version suites me best. Thanks in advance!

[Q] Trying to find the right Modem (baseband) file?

Hello everyone,
So I'm not too good with the whole modem/baseband issue. What I'm trying to find out is which modem file works best with AT&T, and since AT&T sells a different version of the S2, I know I can't use the basebands for that model. Does anyone have a recommendation for a baseband that might work. I'm in Manhattan, KS, but I don't need anything tailored to my area in particular, just something that would work US-wide (I'm coming from the korean version of the S2, so my baseband is COMPLETELY different for some reason)..
Thanks a TON for the help, everyone!

You don't wanna get a branded ROM, you are looking for as stock as it gets ROM (super-hyper unbranded). Forget about AT&T, I really don't think basebands differ from one model to another.
I might be wrong- doesn't feel like it, but I might-.

[Q] Verizon-Sprint GSIII

So I looked around the threads on both Verizon, and Sprints side of the fences for an answer to this question and couldn't find any thing.
I have a Verizon Galaxy S3, and my contract with Verizon recently came to a close. I want to switch to sprint due to pricing and other options, but I don't have the money to drop on a new phone at the time, so I have been looking into unlocking the phone to work with Sprint, however I haven't much of luck...
That's when I came to XDA. While I was looking around the forum, I got to thinking.
Is there any possible way that I could take the Sprint version of the Samsung Galaxy S3's ROM, and load it onto my Verizon Galaxy? And has anyone tried this yet?
It's essentially the same hardware, right? To the best of my understanding, the only difference in the phones would be software related according to the carrier.
I am really struggling with this one, and I have witnessed the vast knowledge and great work by this forum before, so I am hoping I'll be able to find the help I need.

Verizon and Sprint do use the same cdma networks but will not activate each others devices on their network so the answer is no I do not think this is going to be possible for you.

Well I did talk to Sprint, and Sprint said they would be willing to activate an unlocked Galaxy. It's just the unlocking process that I am unsure of.

Galaxy s2 poor signal indoor.

Hi i have an Samsung Galaxy s2 and it has verry poor signal,if i go inside house i get no signal at all,only outside i have signal but is not full.Anyone can help me?
Are you sure your network provider provides good coverage in area? If yes, you can try flashing a different modem.
That's normal for any phone/dependent on what spectrum (frequencies) & equipment the carrier uses. I'm in the same situation at home in particular.
Its normal when i enter a building to get no service?
Sometimes. Depends on the building, depends on the topography of the area, depends on the frequencies your carrier is using, depends on the equipment your carrier is using in nearby cells (this can vary widely from area to area even with the same carrier).
Have you modded the phone at all - flashed custom roms/kernels/etc, specifically have you flashed different modems or RIL's ? If you're running the modem that was on the phone when you bought it (or a modem that came bundled with a stock rom released by your carrier if you've done OTA updates), it's either:-
A) One of those carrier-side issues or
B) A hardware problem.
And as Banjara said, the only thing you can do about A (the solution to B is obvious, take it to a mobile repair shop or Samsung service centre) is to try flashing different modems to see if that improves things. If you're already running a modem bundled with a stock rom released by your carrier however, trying modems released with stock roms released by other carriers/in other countries is unlikely to improve things much (if at all) for a very simple reason.
Modems bundled with stock roms released by your carrier have been (one would assume this is the case with all carriers at any rate) tested so they work for most people on your carrier's network most of the time. If you're getting poor connectivity with one of those, switching to a modem meant for another carrier's network probably won't make any difference.
So...Where you go from here depends on your answer to the question I posed in para 2.
Also imei is a generic one.
You didn't answer my question (IMEI's don't disappear all of a sudden on their own for no reason), so I'm going to leave it to other people to attempt to help you here. Nothing personal, but I have no desire to play 20 questions with you/'pull teeth' in order to get the info I need to help you.
Wait until someone else decides to help you.
