3G not working ( intermitten )

Phone shows 3-4 bars of 3G and I get nothing but errors like , Page unavailable...this app needs data connection....etc. Sometimes if I disable mobile network and re-enable it it will work for a few minutes but then gone. Am I the only one ? I searched briefly . Nothing informative . Help please .

Call att and tell them to connect you to the specialist, i had the same problem and i was literally on the phone with him for 10 seconds and he fixed it

Sometimes it does similar to me. It will sit there and go from 3g to edge to 3g to edge. I've taken to just using 2g when I have wifi, then 3g when I want mobile data. Although now that I had the phone for a while, I kind of know where 3g is strong.

Need Help !!!

My phone has stopped working 3G for one day until now( i've used for 1 month) even I try everything such as active, deactive ,reboot, up rom,...but it didn't work at all. I can't see the signal of 3G on the top bar. I don't know the reason is. Could you please help me ?
(I use Vodaphone carrier network in Australia)

Factory reset?

I've done that but it did not work even though in stock rom or cook rom.

Could also possibly be a problem with the network... Masts do break down. Have you tried your sim in a different phone?

Signal help

So I bought this phone about a week ago, and have noticed something rather odd...the signal is never locked, it is either emergency calls only or mobile network not available or it does work...but when it does work it lasts for like 3 minutes... I live in Honduras and don't know what the issue might be.. I used to have a captivate and had the best signal one can ask for...any help?

Try flashing a different modem. Check siky_dudes thread in dev section.

silkys thread is only for cm7/cm9/miui modems!

Im running ics aokp milestone 4...the problem persists...is there any modem thread you guys can refer me to?
Sent from my GT-I9000 using xda premium

It'll not help to flash another rom or modem! I had the same problem, tried almost every modem/rom but couldn't solve it. I think one out of 100000 i9000's has signal problems.
I don't recommend to do this;
I used to solve it by plugging in an isolated copper wire into the coaxial input on the back of the device. Here's a link to the thread I started with two videos.

Dude, give that thing back if you can!! Nothing will help! You can do whatever you want, but you'll never achive more than 7-15% more signal and that's nothing relevant!!

i have same problem after new ICS updates it take like 1-3 minute to get network signal i tried different modems and still nothing

It has improved inside the city, i go to school outside of town and there I have no signal...at least I can call and text from home...

First of all you should determine what might have caused the error.
Signal problems can be caused by hardware, software or network provider:
- If the problem occurred after a software update (which is usually change the modem driver) You should flash back the old modem
- If you didn't update or change firmware or the modem it can be a hardware issue (dropped phone, water damage etc.) If you don't experience hw you wouldn't disassemble.Give it to someone who has experience in this topic.
- Sometimes signal problem can be cause by the network provider (network error or upgrade) It is usually temporary problem you have to wait and get good signal few hours/days later.
I hope I helped in the first step to get to the final solution.

Constantly losing signal. Am I alone?

Hi everyone, I've noticed a small problem on my phone ever since I've purchased it. Many times the phone's signal simply goes off, what really annoys me is the constant packet data loss, sometimes I havs to reboot the phone to get my mobile networks back on. Changed kernels several times same with ROMs but that doesn't seem to be a solution. I did not make this thread to ask for help but of curiosity if I'm the only one with this. Kind of reminds me of an iPhone video I've seen long ago about how it loses signal once you put your finger on the corner.

It happens. Usually, if my signal is lost, I'll activate the flight mode then deactivate it afterwards. Its like "restaring the signal". Otherwise, search at google play for signal booster.

i get it too and do the exact same method but you're right it doesnt work all the time

How could have Samsung missed out on this problem..

I have the same problem here, I had another phones that has signal almost everywhere I go, but my Galaxy Y loose signal even when its not moved! My sister has a LG E400F, and the signal is preety good. Really annoying.
Btw, I have a bug, when I am only in emergency call, my phone shows signal bars, like if I had signal. Anyone have this bug too? And is only on stock rom.
EDIT: The bug that I have is from the firmware UTKL from Brazil, I tried another firmware version and have no bugs.

Think I'm gonna send an email to Samsung. Wonder if it's hardware related.

good thing I have good and consistent signal with my SGY.
I have two SGY cellphones, both have strong signal even when I'm inside a building.
I hope you can find answers to your prob.

my signal is like that last 2 weeks ago... my brother and classmate who own SGY lost signal also but its now back to normal i think its our phone has a problem maybe if they released a new firmware.. it will solved this

same problem here bro...my SGY loosing signal too even you are not moving i can get signal in the office but other places i cant get signal

im with you

well from my observation mybe this is related with busybox version you have installed. I recall you mentioned using custom kernel right. try reflashing stock rom or try another custom roms. i previously have signal related problem with chobits rom when I updated the busybox.

I'm also losing the signal of my SGY.
And sometimes it is in weird state that my signal is at 3 bar but status says that it is for 'Emergency Call' and I can't call or even text.

Defy signal problem

well, its simple.. i got defy plus, in stock rom my signal and 3g works good... when i put a costum room like saphire light edition , cm 7 or jelly mokee, or whatever rom my signal and 3g get ****ed up... in some roms i got telephony layer problems, in other roms just cut the signal and no call working or sms or 3g... i see some people with this problem, i dont wanna use it 2g, or GSM , i want to repair this damn problem and use any costom rom with no worries,
sry for bad english im from argentina...
plz, give me a solution :/
