Radio Question - Galaxy S III Q&A, Help & Troubleshooting

I have had several Samsung phones and they all seem to have weak signals compared to other phones.
When you get your phones please let us know how your signal and reception is on the sg3.

Radio
Currently running I9300XXLEF - Omega v3.0-ZSALED. CWM & rooted yesterday using Chainfire's procedure. Radio seemed ok from stock and post rooting. Then yesterday evening started dropping out. Lined up all families phones on kitchen table! Desire 2 bars, HOX and SGS2 2 bars however SGS3 "No Entry " sign, all phones on Orange/T Mobile. This S3 is an unlocked phone from carphone warehouse.
Having now flashed Omega v3.0 same problem persists, reception weak at best. -107dBm - 1 asu both before and after flashing Omega v3.0.
Any comment appreciated.

HTC Hero && Vodafone whats the best Radio rom

Hey people,
I always had an HTC with windows mobile.. i always had non-provider limited/customized devices.
Always had problems with the normal radio's that i didnt get much signal, always under the 3bars.
So i always looked on this forum what should be the best radiorom for the device to get better signal.
Now i have an HTC Hero with android, never flashed, never done anything with android eighter.
Its now 8 days ago that i bought myself this hero and always am under the 3 bars signal. some times i dont even get signal.......
Is here someone with the same problem?
I have Vodafone NL, they always change the radio-rom to the best fit when the phone is branded, but the hero doesnt even have an branded vodafone NL Hero!
So please help me with chosing the rom and point me to the best direction of an how to flash radio rom
I've looked around and didnt realy get an answer on this, so thats why im asking.
Thanks in Advance!

I'm not using the same provider as you. But I find:
63.18.55.06_6.35.05.31 saved a lot of battery compared with others
63.18.55.06IU_6.35.08.22 seemed to have better signal
63.18.55.06JU_6.35.09.26 the lastest one, seemed kept a good balance between signal and battery.
NOTICE: Signal bars do not mean everything, with 63.18.55.06IU_6.35.08.22, if I've got only one bar, that means I can hardly make a call, but 63.18.55.06JU_6.35.09.26 will give me better performance even with only one bar.
That's all I've got. And am talking about gsm Network, not 3G.
Legend....
This topic is old... bu tmy post is a little off topic... so....
I have the same question regarding the legend.
I bought a stock standard HTC Legend, but Vodafone has bad reception, even no signal.
Tried 2 SIM cards from Vodafone, and one Telfort, the Telfort/KPN Sim card works fine.
So, i am also wondering if there is a special Radio ROM to use with the legend.

Three UK branded S2 default modem?

Hello all
I'm just wondering what modem do the three branded s2 handsets come preinstalled with in the uk? I'm trying to find good modems for my s2 but cannot find something that would work as well as I would want it to. For example the other day my mate with a wildfire, on the same network had full bars of signal, whereas I had barely 1 bar. I was using Ki4 at the time, now I changed back to kl1 (im on checkrom v6 atm, but planning to go to cm9 again). Can anyone direct me to the modem.bin file or a stock rom file from the Three branded handset, i'd like both a gingerbread stock and ics stock rom from them if possible. If they are modems which are easily available please share the names with me.
Thank you
EDIT:
I tried a number of modems, which includes NELP2 which is meant to be good with three, although I don't know why I have had this problem on several roms before, where my signal randomly dissapears and goes to emergency only calls. Can anyone help with that also?

I recommend NELP4. It is designed for Three but many UK users use it as it supports great battery life and speeds + signal strength. I'm on O2 and using NELP4 and have great reception in places where there was no reception on LQ5/LQ6
modem signal dropping
hi,
You could try using ki4 modem ive been using this even after rooting my phone (originally used on GBrom) and had no probs with signal drop or overheating as some users have iasues with various modems.

[Q] Weak/no signal

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.

[Q] Poor Note II throttled to death by verizon..or something, horrible 4G speeds!

Im not really sure what is going on but my Note II which used to get 25-30mb/s now gets at best about 1.5mb and more like .8 most of the time. To fix the problem I called verizon and swapped a previously working SIM card out of a Galaxy S3 and activated it in the Note II. Interestingly while the activation was happening I got between 4-6mb/s but could still not make calls. After the activation was complete I am back to piss-poor speeds which makes me think my account is being throttled.
I also swapped the SIM back into the Galaxy S3 and test speeds and they were identical to the Note II so I think the phone doesn't matter. Meanwhile, 2 feet to the left my wifes HTC One M8 is getting near 30mb/s download.
Is it the SIM or am I being throttled to death. The phone shows 4G properly and has great signal strength (4-5 bars). I also disassembled the phone and checked the antennas and connections and everything seemed good. Oh and I am totally rooted running SR1 KitKat ROM which is touchwiz stock based and never gave me issues before.
So stuck and unhappy.:crying: Any help is much appreciated.
In case anyone runs into this type of thing. The fix ended up being a total ODIN back to stock/locked 4.12. Then I ran Casual, unlocked everything, and loaded SR1 4.4.2 and after booting everything is perfect. Nice fast speeds again.
According to other posts flashing tons of ROMs, Ie, TW, AOSP, CM, etc can eventually lead to this slow 4G behavior. The fix is Odin back to 4.12 stock and Re-unlock!

I'm new to the S2... my vs980 got crushed and this thing is a learning curve.
It does WIERD ****! Like, it demands I turn on "Data" to send a picture MMS, or recieve a group message , or God Forbid somebody on iphone (which I think sends mms by default) send me MMS.
I mean, it demands mobile data when me Wifi is "ON and STRONG"
Is this a Samsung thing, I verizon thing, a ROM thing, and will rooting it and dropping somethine that's not BROKEN into it help?

4G connection problems. Help!

Good afternoon,
I have a galaxy s6 925i,
I'm having problems on the network,
Performing some tests and realized that the problem is with the cell phone.
Before my phone took the 4G network normally, after I switched to the NN4 ROM I realized that my 4G signal did not work anymore. I thought it was cell phone coverage issues.
I changed operator and continued with the same problem.
I changed the ROM, did the wipes and nothing.
I put the original ROM, I installed the MODEM file and CSC and it did not work.
My wife owns a Galaxy S7 and I use my chip normally in 4G.
At the moment I am with the ZTO ROM my signal is very intermittent and I do not know what to do.
If anyone can help me.
I thank you all.
