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.

Hey all! I have a very odd issue with my SGS II i can't figure out.
I bought a SGS II from Telstra outright and rooted it, installed CWM, installed CM9 and had been happy for about a month. Last night i flashed a few different roms to try them out (being a massive MIUI fan). Anyway, after flashing a few roms and playing around a bit i realised my phone was no longer connecting to the Telstra network and the signal icon was grey and no apps could use data and only rarely would it check for messages, often getting 3 or 4 sms's at once.
So i flashed back to CM9 today and still have more or less a mp3 player since it refuses to connect to telstra.
I have tried many many modems including all of the telstra shipping ones and wiped before and after each to make sure they stuck. (An idea from whirlpool in my readings).
Also i have tried many different roms.
Can anyone shed any light on what is wrong? I should get full reception from telstra in my room, it being the dominant network in Australia.
Also, when i choose search for networks it just keeps saying it is looking for networks until you quit it, and i have full bars on the roaming network, presumably optus or vodaphone.
Thanks!
Okay, turns out i just needed to re-seat my sim card (remove and put back).
So yay! Fixed!
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?
Hey,
I've got a Galaxy S2 that used to be locked on Vodafone AU but was unlocked with an unlock code from their website.
I've put a Telstra SIM card in and the phone worked flawlessly.
After I've put CyanogenMod (latest) on it. I hardly get any signal indoors as well as outdoors most of the time. Often it show no signal at all and only emergency calls.
I've tried different modems over the last few days without any luck.
I put a stock Vodafone on it again without any luck too.
My SIM card was replaced by Telstra already, seemed to improve a little bit, but its back to no working again,
I've put my SIM in another S2 and it had full signal this was in the same room where my phone doesn't show almost any signal.
I've seen lots of posts here and other forums with similar issues, but no one seemed to have a solution really...
Does anyone has any suggestions?
Regards
If you bought it from Vodafone either on contract or outright (did Voda even sell them outright ?), there's a fair chance you have an I9100T, which is slightly different from the I9100 so far as the output of the radio is concerned & the modems which work well with it.
Check the bits & pieces you got when you bought the phone (box, receipts, sticker on the phone chassis under the battery). If you do have an I9100T, it's time to try more modems; in particular start with modems bundled with stock roms released by carriers who sold the I9100T (in Australia, Israel, Thailand & NZ). If you try all these & still have no joy, try every & any modem you can get your hands on (there are dozens).
If you have an I9100, it's still time to try more modems, tho the last sentence in my previous para holds I.E try any/every modem you can get your hands on.
And as I've said to several people with similar problems on here lately, I'm (again) surprised that it's assumed this is a phone issue when everything you've said points to a carrier side issue, or at the very least the phone not playing nice with the carrier's setup (gear/spectrum used at individual cell) - I.E it worked for a while then didn't work.
You haven't found a simple solution because there isn't one. All you can do from your end is keep trying modems. This has been the case since the S2 was released 2 yrs ago.
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.

Didin't flash any roms,or modified the phone,its a second hand unit i bought from a guy.
Hey guys,
I have a pretty unique problem and im not sure there even is a solution, but here goes.
The story is that I had been living in Canada for the last 7 months or so and bought myself a shiny new Desire 601 from Virgin Mobile (its a zara_ul). Since then, I have managed to brick it hardcore style, but i was able to ressurect it after 4 months of fruitless attempts through various odd files, sheer dumb luck, and the RUU from mrplowdans google drive (super props by the way, you saved my phone good sir!). I had to SuperCID the phone in order for the RUU to stick.
So it goes without saying that im now running the Telus version of KK (i updated through the usual OTA once i had returned it to stock 4.2.2) on a VM phone. All good, no issues there. Ive since returned home to Australia, unlocked the phone so it works with an Australian carrier, also all good. Im able to make calls and send texts no issue.
My problem is with mobile data. It seems to be having an issue connecting to my carriers 3g/4g. Initially, there was nothing at all, just the bars in the notification bar telling me that i had a good connection to cellular. No little superscript 3G though, and in settings, although mobile data is 'On', it is showing connection failed. Adding a custom APN appeared to work slightly, the 3G appeared in the notification bar and in settings, mobile data was shown to be 'connected', but still no dice when i try to connect to the web or download an app.
Now i vaguely understand the principles involved here, I get that North american carriers use a different radio frequency to, say, Europe, and that differs again to Australia. My question is, is it on the software side? Would it be possible to find an Australian Radio.img for a desire 601 (i dont even know if they sell them here), flash it, and all will be fine and dandy? Or is it the physical antenna inside the phone that is set to receive only a certain frequency? Im not expecting someone to go and find me a working file or anything, i know most of you live in Canada anyway, but im looking for someone with a greater knowledge of these things to find a theoretical fix.
I know I rant a lot, but in the scheme of things im willing to let this problem slide considering i only just un-bricked it a few days ago AND managed to root 4.4.2 (a significant achievement given my non-existent knowledge of android), but it is a nuicance and if theres something simple i can do of course i will.
Thanks in advance for any help <3
EDIT: Ive since done some googling and discovered that they do sell these phones in Australia, and that the Network specs for it and the canadian model that i have are almost identical, many of the frequencies are the same on both. Leads me to assume that its software sided, the telus radio.img is telling the phone to not see non-canadian frequencies.
