S3 Network issue! Slow internet! only GPRS. - Galaxy S III Q&A, Help & Troubleshooting

I've Samsung S3 GT i9300 SHV E210 L and when I check my APN settings it does have LTE option under Bearer but currently my Telecom provider doesn't support 4g. However they do provide 3G with a great speed. I hv used it on other mobiles and it works great . It's just this phone gets only G when selected GSM/WCDMA automode. When I manually select WCDMA only it gets 3G but very slow speed and it drops out very frequently. The maximum speed which I have received is around 1 mbps only.*Please provide me with a resolution how I can I get good bandwith/speed. ?

Change modem,is the only thing you can do...control in samfirmware site what's your last stock firmware supported by your device,in you country with your provider. There you can see the base band,use that for looking for the right modem and try to flash it. The wrong modem can drain your battery or could kill your network

S3 Network issue! Slow internet!
And this phone is a Korean S3 with 2GB RAM and 32 GB ROM and it always warns me about data usage in abroad. I use this phone in India.
It gives me error like registration failed contact customer care. And ya my battery drains very quickly. If you can please give step by step process to fix this issue it will be great.. Much appreciated.
thanks.

Give me time start from samfirmware!

I'm sorry but we have 2 problems:
first,your device can't be a GT.I9300 because has 2GB ram...
second, on samfirmware KOREA doesn't exist,so i can't quickly know what base band is used in your country :/
Haven't you the stock rom??

[Q] 2 questions on 3G/H

hi!
i am using a tmous hd2 with the stock 2.13 rom and the recently released 2.15 radio. up till now i havent really bothered using packet data on my phone because i am a wifi guy... only recently did i start using packet data frequently...
i noticed two things out of place:
1) for some reason i have never seen hspa service on my phone. my operator runs a 3.6mbps dl 2mbps ul hspa services. whenever i switch to 3g and connect data, i always get a 3G written over the signal bars. and i have never seen speeds over 42kB/s (~384kbps) in several months of use. i have full signal strength in both 3g and 2g. if i am running 2g, then i get an E as expected over the signal bars. i have put in all the access point settings as defined by my operator (which are common for both 2g and 3g). i have enabled hsdpa/hsupa from winmo settings->connections->advanced n/w. is something amiss with the hspa settings on the phone? i really want to confirm that i have my phone set up right before i muster the courage to call up customer care.
(for someone from bombay, india, i am running mtnl 3g prepaid with following settings:- ap:gprsppsmum u:mtnl pass:mtnl123. this in itself is quite baffling because mtnl delhi has separate aps for 2g and 3g whereas the bombay network has the same ap for both. ap=access point)
2) i have never seen the H/3G/E/G icons on my taskbar. i mean the ones that are NEXT TO the signal strength icons. the space between the headset and the signal strength is always empty. isnt that particular icon supposed to show 'availibility' of the respective type of data connection? i read somewhere a long time ago that the icons are ROM dependent. but i am pretty sure i have seen snapshots of tmous phones with those icons...
i have been using bsnl cellone 3g since feb and i always got H in south india, even while roaming,...in few cities up north, like lucknow, i got only 3g icon displayed..i guess it should be H in mumbai..
from what you say, i think you have not enabled HSDPA/HSPA setting in the phone...do that..it is in settings/menu/all settings/connection manager or ?phone / advanced network ( i think...can't tell exactly where...iam presently on the android side...)

no, i have enabled hspa (both directions) from advanced network. i said that in my original post as well. what windows rom were you running? also did you just get H speeds or see the H icon as well?
both H icon and speeds on 1.48 wwe and 3.14 wwe roms
Hi I use an unlocked TMOUS HD2 here in Italy with the italian carrier PosteMobile and experience the same problem of silenced3 (almost the same as I still haven't tried a cellular data connection): My phone doesn't show the kind of cellular signal available, only when it data connection is activated it says what type of connection it's using. Anyone knows how to solve this?
Thank you for your help...

Modem bad reception in Canada Galaxy s2

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

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.

HSPA issues

I have a International Galaxy S3 I9300 bought in India and i have come to US and have took a TMobile connection. Now the issue is that , im not getting 3g(h,h+) speeds all the time. I have set my device in Auto(GSM/WCDMA) . I have another guy under same roof using same Tmobile conn (Nexus 4) and he is getting 3g speeds and im not. Its showing as Edge('E') in my phone. I can confirm that the 3G is working at some places near my apartment so its not an activation issue or something. Does it has to do anything with the ROM/kerner . I have been using the Foxhound/Persus combo. Should i change the modem settings?
Try setting the Network Mode setting to WCDMA only (instead of auto). I am on AT&T, but was having same problem in certain areas and this fixed it.

Yes, i tried this, but the network goes blank. I'm sure im covered under a 3G area as the other guy is getting awesome speeds under the same roof. Was it because the other guy got his mobile in US(Nexus 4) and i got the international version that it could not read certain spectrum? Really confused.
Did you compare APN settings with other phone? Somewhere here there are probably APN settings that are optimized for T-Mobile. Or may find them on Google.
My gt-i9300 does the same

I'm on omega v35 and I have tmobile as well. it seems I get this edge all around were I live but then I'll go about a mile in any direction and I'll "all hspap??, 4g, 3g., all" I guess thats because of the towers mabey and the fact that I have the international as well. If any one knows why I would like to know as well.

very slow 2g speed

Hi
I'm experiencing very slow 2g speeds these days I think it's modem problem because my brother who's using same network(vodafone) is getting around 3x speed compared to mine, both on same plan but he's using grand and he's on official rom and I'm on neatrom
How can I fix this? If new baseband please suggest me one especially one which works well in India - Mysore
Currently I'm on neatrom 4.2
Baseband xxms2
Switch to 3g.
Sent from the little guy
I got wifi in home so it's waste to spend money on 3g which is costly in India
2g, 3g or wifi? Which one is it?

Mate, staying on 2G is a viable option only when 3G has a poor connection and drains battery. The only difference is the speed with which pages are loaded and data is transferred. The only noticeable difference in the volume of data is if, on a good connection, you browse more pages because they simply load faster.
You may be referring to WiFi, which is another story.

S6 Edge Network Mode

Hi Guys,
I've just flashed EE firmware on my BTU S6 Edge and the network modes now shown are 4G/3G/2G instead of LTE/WCDMA/GSM. I've got double speed package from EE and was previously getting 4G+ sign but not anymore. Please can someone help in this matter.
Thanks
Panesaam
download a speed test app from the Play store and check the actual connection speed. It seems some firmware variants will show LTE and some will show 4G.
I'm on a 925F unbranded on ATT and get the 4G symbol yet I have LTE speeds, as confirmed by a couple of speed test apps.
Hi Devis,
Thanks for reply. I've already checked it and I have lost 50mbs from my download speed on speed test. Normally I would get around 100 mbs download speed with 4G+ but now I getting approx half of it. I have flashed original BTU firmware back and my speeds went up and now shows LTE/WDCA/GSM as Network modes.
You know, here in the good old US of A we're lucky to break the 40 barrier and just yesterday I upgraded my internet at home to a 100mb connection. What I'm saying, with these phones, there is probbably nothing that you can do with 100 that you can't do with the 50. But, yea good find.
We'll that's true. More speed ain't gonna make difference. Instead data will be consumed a lot quicker for no reason. I try not to panic as long as it works. Thanks a ton and A very Happy New Year:good:
