Maybe its just tmobile, ive had the same problem for a while now, its just that i rarely get 3g and then some days i get it for ours

Maybe try flashing a different modem. Since you are in Mexico another one entirely might be just what you need.
i try flashing a couple of modems but still no luck is there any modem that you can recomend please

I've got my unlocked Vibrant running on AT&T, but I can't seem to get it to switch between Edge and 3G. I can go into the settings and set it to stay in WCDMA mode, but then when I'm in an area of bad reception I end up missing calls (All through VOIP).
When its setup for Edge/WCDMA it will stay in 3G at first, but when 3G gets too low and it goes to Edge it won't go back to 3G at all.
I've tried switching modem versions but I'm guessing its unrelated to that.. well, actually all Vibrant modems are going to be setup for Tmobile anyway, maybe a Captivate modem is the solution, I'll try that and get back.
Does anyone have any ideas of how I can get it to switch properly?
If this modem install doesn't work I'm all out of things to try.
Thanks.
As far as I know (and I could be wrong), you can't flash a Captivate modem to the Vibrant, it just makes the radio useless.
You will have to use Vibrant modems, since they are designed for the hardware IN the Vibrant.
Hey Guys,
I've got my Vibrant on AT&T but I seem to have a problem with the Vibrant modems, whenever I'm on the 2g/3g mode it'll stay on 3g until theres low reception then it'll drop to 2g. The problem is that once it drops to 2g it won't go back up to 3g, no matter if reception increases.
I saw a post in the development section about I9000 modems working on the Vibrant on the CM7 ROM, I've been trying the modems on the latest CM7 nightly, but even though they install fine I'm getting truly horrible signal. I've also tried a couple Captivate modems but I'm unsure whether they're meant for the CM7 ROM on the Vibrant or not, nothing I've tried seems to work well.
I'd post in the development section but I'm low on posts so I'm not allowed:
Would anyone know if I9000 or Captivate modems would work better on AT&T?
And possibly where I can find the modems that would work on the Vibrant with CM7?
Thanks, this problem has been bugging me for awhile already..
In Chicago area I have very strong 3g signal so it does not drop to 2g. On the other hand, when I was in Florida my phone stayed on 2G most of the time, but it would switch to 3G in more populated areas. I use KB5 modem.
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.

Hi guys. Me and my wife both have gs2 and we both are on tata docomo 3G network. The speeds are good and this phone is awesome, specially for someone coming from a blackberry like me. However there is a peculiar problem both of us are facing. The data xonnection sometimes hangs on 3G and does not move to h or h+, and in 3g therd is no data transfer. The data transfer happens only on h+. That means for all practical purposes there is no data transfer. Sometimes it alsi so happens that the phone is showing the h+ icon but again there is no data transfer and i cannot access any internet related app. In these cases when the data hangs the only option is to activate the flight mode and then again reconnect. Then the data works fine. Off late this has started happening a lot. I have tried a couple of things like deactivating h and h+ and working only on 3g but to no avail. Can anyone help with this. I have not been able to test on other networks so i cannot be sure whether this is a device related problem or due to the network. Any help would be highly appreciated.
Regards

I am also facing this exact issue. I am on Airtel (India) network. For me, it seems to happen when I am at some particular locations, and works smooth at some other locations.
I just deactivate data network mode and re-activate it (long press power) instead of flight mode, takes only 10-15 seconds.
Don't know if rooting and using custom roms will fix this issue, because I strongly believe it to be network-related. I used to have similar problems with HTC Desire with various sense/AOSP custom roms.
He y buddy. But if ur on airtel and i am on tata docomo and we both r having the same problem, maybe it is not a network problem and is rwlayed ro some handset setting. Did u try the *#302179# trick. Did it work for u. Same problem in othe networks and for some of them this trick worked.

And by the way thanks for the data connection mode trick ( long press). Atleast it is a better way to make it work.

i have the same problem i.e data loses connection. after a fresh flash of stock rom and factory reset , it starts working fine for a week or so and then the shyt happens again . i can tell u , its not a hardware issue, it more like a software issue.
i m not good at android but wen i used to run squid on a linux machine as a proxy server , i recall i had to clear a log file to make data flow possible every few days. i think android has a similar issues some logs files build up or some **** like that.
Happening to me as well.
I always thought it was vodafone's poor network as my phone never downloads data when 3G is showing, it will only show upload arrow, then when it change's to H I get both uplaod and download arrows and starts working fine.
One thing I did notice though is when in Gran Canaria 3G was showing and working and data speed were ridiculously fast compared to here in the U.K
Surely this must be related to kernel used???
I have the same issue on my I9100 KI3, KF4, KG2 stock rom with either KG2, KF4, KI3 or KI4 modem. This is a combination of tower and our phone modem or kernel issue. I am having this issue with AT&T USA on KI3 and KI4 quite often in Champaign, IL. But when I went back to my country in Asia(Taiwan) 3 months ago, KI3 rom and modem have no 3G issue at all. I was on 3G 24/7 for 3 months without any issue there. However, I had the same 3G issue in Taiwan when I was on KF4 modem with KF4 rom when I first bought the phone. This is really a funny issue. I tried all the tricks and switching so many rom and modem, but 3g hang still happens to me with AT&T network. Now I am trying to lock the WCDMA band to 850 only, see whether it helps.
having the same issue here, but im quite sure its network related, inside my office the 3g dissapears at all and the same happends to a friend of mine who owns a SGS2 as well. whenever my outside the internet works as intended
also flashed trizillions of roms and modems before i gave up and blamed it on network rofl
Okay everyone. After alot of trial and error. I got my Samsung T-mobile vibrant working on AT&T. I'm running Whiskey Nextgen 2 Rom and everything seems to be working fine except signal strength. I've read about how the Vibrant only picks up 2 of the ATT signals or whatnot but I have NO signal inside the building where I work. My question is whether an AT&T radio can be flashed to the phone so that its basically an AT&T phone with decent signal. Any help would be greatly appreciated.
Yeah, you can flash a captivate radio.

My girlfriend is using her vibrant on ATT without any issues. How good was the reception in the building before getting a vibrant?
T-Mobile Vibrant not working on 3G network from AT&T
Could you use 3G with AT&T network?, because I couldn´t, just Edge, which is very slow,any recomendations on this matter? I heard this device doesn´t support 850 mhz, is there any way to make it happen?

No 850mhz. You can get AT&T 3g in the areas they use 1900mhz though.

Well I had a Captivate but it was stolen from my home during a burglary some months back. I had left it home because it was one of those "shut off" models that would constantly shut down on it own and I was using my more dependable iphone 3gs while at work. That being said, I had 3 bars inside the building. With the Vibrant on the ATT network, I'm sitting at 0. Cannot connect to the market or anything. At home, the Vibrant signal is fine but I need a happy medium and I'm still recuperating from the break-in so I cant just go out and purchase a new ATT phone at this time.
The more I read about flashing radios though, the more concerned I am about doing so. I was under the impression that the radio had to match the kernal and my kernal version is 2.6.32.9 so I dont know if the cappy radio will match.
