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.

Hello. This post will be changed depending on the needs of the topic.
So I use Bulgarian network sim card in Netherland that is in roaming with Vodafone network.
I buy SGS2 in Bulgaria. The phone came in Polish and is scored by Poland. Modem is KI4. whatever...
So what is the best modem for me? Bulgarian network mtel connected via Vodafone Netherland.
Yes, I understand that my answers to the most logical to have my data with users who have tested various modems.
But how to understand different types of modems specifications.
I understand that there may be no big difference in modems operating in roaming, but instances to me is that the phone works and only works in roaming.
I hope if you are constantly roaming as I to describe modems and networks that you are using.

I dont really understand you, try adding a dutch version of what you want to say?
As always just try all the modems .
jje
Are there any criteria?
Phone does not use 3g, only wifi.
In all modems made a call, how to know if there is palpable delay or otherwise.
And I suppose important is battery life. This test will take months until all test modems and I guess the difference is unlikely to be large which is why I want someone to explain the operation of any modem while roaming. What resources are used while roaming.
Not long ago I flew from Oslo to Moscow and my phone had one of the latest GB-ROMs. In Oslo my phone worked like it should, but when I landed in Moscow I couldn't get any connection. Fortunetly I had several modem files on my phone and I flashed one of them and got connection.
This time with an ICS-rom (LP2) which is Russian I have no problems in Norway nor Russia.
How can we know if our phones with the installed modem version will work when we are travelling Wordwide? For us with rooted phone we can stack a bunch om modem files when we are travelling but for those who haven't rooted they will have a problem.
I can't beleive it should be like this. Or maybe my experience was out of the ordinary and a one time case?
You can't know for certain, apart from other users' experience with using various modems with different networks (or your own). Different modems work better with different networks sometimes. Fact of life.
If you've got a rooted phone, keep your modem collection on your SD card so you can flash them with CWM when you travel.
People without rooted phones, bad luck. They can talk to their carrier about poor reception or data speeds. Us who like to mess around with our phones can do something about it (try different modems).
SGS2 is no different to any other phone, some networks & in some areas you're going to have problems with reception/data.
I'm creating this thread for anyone running on a 3HG network. There seems to be problems with custom firmware not being able to differentiate between the 2G and 3G networks.
I'll explain. I'm currently using a custom ROM and very happy, however, the stock rom seems to have some built in special features to detect the 2g and 3g portion of the 3 network separately and ban roaming unto other networks. (For example, O2, vodefone etc say (not allowed) next to them when searching with stock rom.) I know 3 does not run their own 2g network and the 2G portion is "roaming" onto vodefone without charge. Even though the phone detects the 2G portion as "3", whenever you connect to it the phone goes into Roaming mode. However the stock rom default is to "Allow National Roaming" (An option not present in my custom rom) and the stock rom then bans other networks besides 3 so that you can't accumulate massive data charges.)
I assumed that this feature was built into the .csc portion of the stock ROM. However, this is not the case.
I was able to download the csc portion of my rom from androidfirmware.net.
Unfortunately, I did not solve me problem. I'm on 3 Ireland. My stock rom can breakdown the network information into two networks:
3 (3g)
3 (2g)
It then selects the best one based on signal.
Unfortunately, myl custom rom (omega 13.1) just see two networks named as:
3
3
It doesn't switch back to 3g ever. It's a shame, I thought flashing the csc and modem from stock rom would fix this but it doesn't. I might have to always run stock firmware.
On another note, for those interested in modem files, regardless of which 3 Network you are on, you MUST run either NELF1 or NELE modem on your rom. I have extensively tested all modems and 3UK/IE are setup to specifically work best with these two modems. The download speeds are very fast, but more importantly they are consistent. I was able to obtain better speeds with some other modems but it would stall and hang and drop. These speed bursts did not make it faster overall. My signal was about 1/3 of the 3uk modems with all other tested modems. If you flash any custom rom you will notice a vast improvement in battery life, signal and consistency using one of the above modems

I have not tested between the two, I tried the latest version NELF1 and was blown away by the difference so just kept it. Cheers!
Any help with the above network differentiation problem would be appreciated. Feel free to post your thoughts or comments or suggestions.
Thanks.
Its well known that the NE modem range are better and even better than stock for some on non 3 networks
First general release was. 3 Ireland
Firmware info: PDA: XXALE8 | Phone: NELE4 | CSC: 3IEALE3
UK 3
Firmware info: PDA: XXALE8 | Phone: NELE4 | CSC: H3GALE4
Same modem different CSC
jje
I run every sort of Rom on my phone and never have those problems.
Using XXDLH9 modem now and pulling 6mbps down and 2-3mbps up and I live in the country, haven't used NELE4 since the day I got the phone.
Also in regards to the roaming and the massive charges, you won't incur any charges when you roam in Ireland, it will use Vodafone and that's it, even then they only let you use 2g data too and that's not charged either.
You must get poor signal where you are seeing as it keeps dropping back to 2g, try going into settings > more settings > mobile networks > network mode and changing it to wcdma only wait a few minutes and see how you get on.
To add to that: as far as I know NELE4 and NELF1 won't work on new firmwares. Voice calls get messed up, you can't hear them or they can't hear you.

Hi there, I have exactly same problem with I9300 and Three Ireland, did you find a solution ???
I have two Three simcards and problem is only with one of them, I even replaced this simcard for another one but with no luck
any help?
thank you

Hey lads,
Did anyone ever find a solution to this problem. I'm on three ireland. I've an old galaxy s young with always stays on H/H+ and never drops to egde no matter where you are where as my new S4 consistently drops to edge over H when coverage is low.. is there any solution to this problem? I've flashed on the three firmware from sammobile but it's no fix!
Eoghan.
I'd also like to find out if a solution was found for this? Does anyone know how to go about modifying modems or something along those lines that could solve the issue?
I'm in Japan for this year and I've just purchased a B-Mobile Free Data Sim (with voice), and while I can use the phone service, I can't use Data. After looking at b-mobile's GUARANTEED to work devices (bmobile.ne.jp/english/devices.html) other versions of the Galaxy S2 are listed, but not the i9100. However, in the list of acceptable bands, the following is written:
"Your device must support one of the following frequency
LTE Band 1 (2100MHz), Band 19 (800MHz), Band 21 (1500MHz)
W-CDMA/HSDPA/HSUPA Band 1 (2100MHz), Band 19 (800MHz)"
My Galaxy i9100T (From Vodaphone) should, as far as I know, support the W-CDMA Band 1 (2100MHz), but nonetheless, I can't use data.
I've made sure my APN settings are 100% correct, as according to the bmobile website.
Should I give up on trying to make this work, or is there some way I can get this going? Is there a particular radio or modem I can flash in order to get better connectivity? Otherwise I'm planning on buying a second hand Galaxy SC-02C or something which is on the list of devices guaranteed to work and relatively inexpensive. If you are knowledgeable on this subject, please lend a hand.
If there's any other information you require about my phone, please let me know.
Cheers
To the best of my knowledge, the phone wasn't sold there by carriers (neither the I9100 or the T), so there's no stock roms released by carriers in the country, and no modems bundled with those stock roms which would have been tested with the carrier's network as would normally be the case.
Sooo....You're probably stuck with trying a bunch of different modems unless a search throws up someone who's posted saying they had good connectivity with whatever modem on that network. If it was me, given the other relatively cheap option you mentioned (and my lack of patience with this sort of thing these days), I'd be buying the other phone if having a working phone without fuss was important to me (which it is).
Cheers,
I managed to get it working, on a stroke of luck. Flashing a few different modems didn't seem to get it connected, but after looking more extensively through the japanese version of the site, i found this page (bmobile.ne.jp/devices/setting_other_androidos.html) which suggested an alternative server to connect to for the APN (dm.jplat.net instead of mobile.ne.jp), even though this is the only page it seems to have this alternative server listed on. My reception isn't amazing, so maybe I'll continue as you suggested, flashing modems, until I can get better reception. Thanks for your help .
Anyway, for anyone who happens to have a similar problem, please try connecting to the above server and see if it works for you.
I am a ATT user with a T-Mobile S5. I have the TMO NF6 Modem but the other day I was in a location with poor reception. My ATT S4 got better reception and I wondered if the ATT modem in the S4 was what gave me a better reception. I then thought would it be possible to flash a ATT S5 modem to my TMO S5 to potentially improve the reception. Is this possible without bricking the phone?

Flashing a non-Tmobile modem to this phone WILL brick it. Even if it were possible, the modem would only be set to demodulate ATT signals, so you would likely not get reception at all.
Umm. sort of. The poster above represents the majority view. And encompasses a number of misconceptions at the same time.
Flashing a modem from another carrier is possible, but neither recommended, nor likely to work well. It may not necessarily brick your phone. But it could if the partition is overwritten. Being tailored for another varient model, it's not at all guaranteed to work as well in your phone. And you would probably find it difficult to get Odin to proceed with the flash. In short it's hard to imagine it worth the risk.
I doubt that the perceived difference between the modems is as large as you believe. And even if it is, your native carrier will update their modem in due course. Or you can try an alternate e.g. older modem in many cases.
