Hey all, i thought i would start a thread about an issue that many canadians seem to have with the GS2, it seems to have been beat to death but there is no actual solution.
Im currently using the GS2 with Telus, its a wcdma/3G/H/H+ carrier using the frequency 1900 mostly and 850 at times on the cdma network, i used so far KG3-KG6 i placed them in that order because KG6 is the latest i tried and has proven to give me better coverage but its still really bad..
I can connect to data but only outdoors or only when the reception is full bars, if i start to lose any bars there goes my data connection and i can no longuer use any services data/sms/mms/calls i literaly cant do anything..
This is a big issue as i know for a fact that you dont need a data connection to send sms. but it seems the galaxy s2 under the current modem firmware im using KG6 wont allow me to unless im on full data coverage...
My question is this, what is the best modem firmware to use according to the frequencies that i meantioned earlier 1900/850 WCDMA i dont mind using another country's modem as long as they are oriented towards the same frequencies that i need
My phone came from Korea and i know they use 2100/900 could that be the issue? Is my hardware oriented towards that? At this point anything could help and please feel free to post thanks

Hmm, I'm a SGS2 owner on TELUS as well and haven't had any problems so far, besides the GPS Lock Time which most people seem to complain about. It takes about 1 minute for the GPS to lock for me, but my data is fine. No dropped calls or sms problems here. My download speed as I checked last was at 8.31 Mbps down and about 2 Mbps up.
But again, having horrible GPS issues. Wish I could figure that one out
Sobai can u post your results to *#1234#
so i can compare my settings to yours.
I'm using KG6 on Rogers network and don't have fantastic reception either. For most situations it holds calls -- but buildings with lots of concrete I lose the signal completely. It's as if I'm not truly on the 850 band ... my G1 had the same problem until I flashed a Bell-specific modem, that solved the problem. I guess we'll have to wait until Bell launches the G2 here, we'll be able to swipe the modem again.
i have an imported gs2 that i am using on rogers and it doesnt drop calls, but i have had times in the past when it would show 3g but not download any data. once i turned airplane mode on and off data would work fine again. the best radio for me has been the kf2 modem in terms of not having the data stalling issue. i find that even if i show no bars of strength i can still download data with no issue.
if you are on telus i would make sure so set the wireless settings to 3g only so the phone doesnt try to look for a 2g signal.
KG2 on a Bell SGS2 on Rogers/Fido network in Vancouver.
GPS locks in seconds. no dropped calls. H+ all the time, never once saw a 3G symbol. no data dropouts.
over 7Mbps down on this network with the SGS2, when i had 1/3rd the speeds an HTC Desire. great reception in my office downtown, my apartment, everywhere i've been so far.
KG2 (not the stock canadian though), in Montreal on the Virgin/Bell network. So far no complaints on the data. Since I started messing w/ the firmware however, the connection is on 3G when idle and only switches to H+ when actually in use. From what i've been reading many people have been noticing this when flashing over the stock Canadian firmware.
On the other hand however, the GPS has been having a hard time establishing a lock (whereas it used to be quite speedy and precise before I flashed). Won`t be able to test whether this is a firmware problem untill the stock Canadian is released by Samsung.

Wow guys I appreciate the feedback I thought I was the only one with this issue! I will definitely give kf2 a try right now and I'll also download the 3G only data app and give it a try and I'll get back to u guys with some feedback. Thanks again
Btw I'm using, touch x 3.2 rom that has kg5 on and I did notice a little improvement in the reception but the data connectivity is still very spotty so I'll give kf2 a try but so far kg5 modem is definitely the best one I seen so far to use on telus. Btw anyone trying to use the galaxy s2 on fido, I was never able to get 3G at all to work I was stuck on edge.

Do you know how I would be able to set it up so that it stays locked on 3G? I tried the *#301279# trick and disabling hsdpa and hsupa with revision 99 but to no avail. Even if it shows full bars and 3G I still get no data connection and also I can't send or receive texts unless there is a data connection for some reason, have you guys had this issue??

i have never needed to mess around with that menu. you should be able to go to
settings
wireless network
mobile networks
network mode
select wcdma only
that will lock it to 3 only. if you keep having issues you might get a new sim card from telus as that might be causing you some issues
Do you have your apn configured properly for your provider? If it isnt your data definitely work. Other then that I havent had these issues in edmonton on kg6 or maybe I just dont know what to expect reception wise. I do notice it hops from 3G to hspa to hspa+ a lot so i switched to only 3g. If anyone finds anything that improves that or reception though I would be interested

This information would be great because I am also experiencing spotty data connectivity (browser loads data, stalls, resumes centuries later) which results in severe crappy data speeds of 0.8mbps down and 0.07mbps up (done on in-browser speakeasy test and speedtest.net app.

I wish there was a way to extract the modem.bin file from the bell sgs2 this way we could simply distibute it around. Someone should root their phone, install cwm4 and make a backup and we could simply pass the backup around so we could all have the modem
Bell modem has already been posted to the forum.

Coming from a HTC Desire, I bought a 6 month old Galaxy S II off a colleague.
I used to run CM7 on the Desire, and was happy with it. So I wanted to install it on the Galaxy as well.
Figuring out Odin and installing CWM was fairly easy, so I was set up with CM7 in no time.
The issue I have is that no matter what modem I use, I can't get a reliable cell signal out of my phone. I've tried some (10ish) different modems from this page.
All of them get 'emergency calls only' sometimes, and dBm values of -95 at best, sometimes going over -106 before dropping connection (emergency calls only).
Signal bars usually stay at 2/4.
If I have connection, I do seem to be able to max out my 3G connection (capped at 1Mbps by the operator) with some modems, but not all.
After restoring stock firmware, I get -77dBm and better, 4/4 signal bars most of the time.
Stock firmware uses XXKE7 modem.
When I tried to use that modem in CM7, I got the same bad results.
I am in Belgium on the Mobile Vikings carrier, which uses the BASE network.
Any ideas on how to troubleshoot this problem?

I'm not sure if you have to tinker with the phones APN settings there in Belgium. Sometimes that is the way to troubleshoot poor data connectivity.
Google "apn settings" and the name of your carrier and see what you can come up with.
Other than that I'd just suggest trying different modems. Hope that helps

It is the open source drivers CM based roms use. I see the same on every device I have run CM based roms on. The generic drivers have less radio and wifi signal strength. They don't use the built in hardware to the Max like OEM drivers do.

I have an SGSII on Telstra running darkyrom XXLPQ with KH3 modem. I've got an issue where data works fine on H+, but whenever the phone drops back to 3G I get absolutely nothing. I've tried disabling fast dormancy etc, but that just seems to reduce how often it falls back. Is there a modem I can use or a tweak that will let it get data on 3G as well as h+?

I think you are better off on T-model modem, like DVKF2 by telstra as that will work on your I9100T model best.
I have the same problem on stock 2.3.4, xeu. But it just about never drops back to 3g in Melbourne. So haven't bothered with telstra modem yet.

I have a feeling you don't understand this very well and if I'm wrong I'm truly sorry. Either move to an area that you know does not have hspa coverage (otherwise known as 3g+ or 3.5g or h+ or 4G in North America depending on the phone model,manufacturer and provider) but rather only 3g and test there and come back to us or disable hspa in hidden settings (phone control/nas control/hspa control/choose r99 hspa off),which should disable hspa/hsdpa and hsupa and test and come back to us. That should give you data while 3g symbol is lit at reduced speed of course.
Right now all you seem to notice that when you engage data it is h+ and when it falls back to 3g, the symbol is only for voice over 3g therefore no data arrows.
Yeah, I'm talking about when I'm I'm an area that has poor hspa coverage and it drops back to 3g. Btw, my old xperia had no problem getting hspa in these same areas, so my radio performance is generally pretty bad with the sgs2.
Try all the I9100T modems until you find one that works well for you; they do generally work better with the I9100T than I9100 modems. And if that doesn't work, then you might as well try all the I9100 modems.
I've got an I9100T & found there's 2 or 3 I9100T specific modems that I get great signal strength/data speeds with (and granted 1 I9100 modem), and the rest are ordinary for me.
There is no simple fix for this. It's a trial and error thing. Unless you want to spend hours on the phone to your telco for probably zero result ?

Threw me off, because of mentioning 'fast dormancy'.
Good that I apologized in advance then.
I would still recommend testing it the second way I suggested just to see whether it works at all. I also sometime end up in an area that while seeming to have full strong signal, due to a congestion at a peak and other factors, has no or very little data throughoutput (this being in canada).
As suggested by others, testing other modems may help as well.
Don't even get me started with sgs2 and nokia's regarding radio.
Hey all. I am running Seraphim with ICS KID T-Mobile modem. The 4G is very inconsistent and I know there are people trying to working on modems to make it better but in the mean time I found that when my phone drops to the "E" signal I get a stronger signal and its a very workable speed. Now I was like some other who made the decision to just go back to the stock AT&T modem until a better T-Mobile 4G modem can be found but I found that the ICS KID modem on the non-4G data signal is faster (for me anyway) than the non-4G data signal on the stock AT&T modem. I asked the question of how can I get the ICS KID modem to just stay on the non-4G signal but the only answer I got was "Go back to stock AT&T modem" but I figured out on my own and just wanted to share with other T-Mobile users that rather than flashing modems over and over again while waiting for a better 4G modem if you go to the
*#2263# menu selct [3] GSM Band Preference and then select [5] GSM 850/1900 you can keep your phone on the non-4G signal. Like I said in my area I just found it to be faster than the stock modem.
good stuff.
im like you dude. flashing every ics rom with every ics modem over and over changing every setting just to get a useable data connection outside wifi

Hi guys,
I'm running I9300XXEMB5 but have been noticing poor data performance, phone constantly goes down to 3g mode even in places I know I have good signal, I assume this is a modem issue? How do i go about finding the right modem? If I install modems I notice no difference in speed, and at my house signal is great so it always stays in H. but its when im out and about I start noticing it, but I don't want to have to keep trying different modems for days on end to see which one is "maybe" better.
Phone is New Zealand based 2degrees model, anyone have experience with this?

There is only one thing you can do: test the modems, you can find flashable files in the General section's modem collection.
Another thing you might consider is that certain providers turn down e.g. H+ to 3G or whatever while you are not using mobile internet, but well that is provider related. (called fast dormancy if I am not wrong)
