I apologize if this subject has been already raised, I searched the forum but didn't find any info on this subject. I didn't do anything to my phone, like debrand or download some new software update, except for installing GDE but I don't think it's the problem. Phone doesnt seem to connect to 3G anymore, Wifi is ok but not 3G. I don't even see the small arrows on top with 3G icon which usually appear when it's out of Wifi area. MMS & data is checked like it's supposed to be. It was working fine before and just today stopped working. I tried restarting the phone - doesn't help. Any ideas ?
Found the problem. Has to reset APN. Juice defender was intruding. However I decided to keep it.
Unlocked X10 won't connect to 3G
I recently bought an unlocked Xperia X10 from Amazon and used the automatic internet settings to set up the AT&T APNs, but I can't connect to the 3G network.

Hi, since I got this phone and I've been having problem with the data connection, wifi is working fine, but 3G is not, it shows the 3G symbol but keep switching to H symbol and back again to 3G constantly, i never been able to surf the web or do anything online on 3g connection since i got it.
I tried putting in the setting from my provider and got the samsung network app thingy but nothing helped, even after updating to NoDo.
This is really bothering me i cant enjoy the phone when im outdoors, i switched back to my iPhone 3gs temporarily.
I really hope this can be solved.
I'm thinking if there is some way to make the phone only works on 3G and turn the H off.

H is for HSDPA and is far more faster than 3G. I reckon you run ADC on startup using samsung tools and hopefully the problems with connection will be resolved. Alternatively contact your sim provider for network configurations.
Here it also switches between H and 3G, or well it did on my other wp7 phone my (european) omnia uses 3g+. That's normal; the H mode probably eats your battery alive, and it only switches to it when your data connection is active (i.e. data is being transferred)
Your problem appears to be an Access Point problem, you can configure one yourself at the mobile connection settings page. (bottom). Check the web for the settings you'll need.
You see most phones are configured automatically by their providers, but the omnia probably isn't supported.
Hope this helps
the APN for China Unicon is "3gnet"
just add it your 3g connection will work.
I'm having random 3G connection issues on my Samsung Focus.
At radndom times 3G connection is lost and the only way to get it working is to turn off and on the phone.
I tried putting the phone into airplane mode, turn off/on data, turn 3G off/on, nothing works, only a reboot works.
Today I checked my email on my phone and it says;
Last updated 4 hours ago
We're having a problem connection to exchange.xxx.com. Try again later.
Last tried 2 seconds ago
Error code: 80072FA8
This error shows up on all 3 emails I have setup.
IE doesn't work, Zune, any app requiring 3G connection.
And this happens at random times, at least once a day.
The phone has the lastest updates and is jailbroken.
One other thing to mention is, the phone is now having the 3G connection issue but i have it theathering to my computer and the internet connection is working while theathered, cause i'm posting this email.
I have no idea what's happening or how to fix it.
Thanks
same with me. are you using another carrier ???
Mine is unlocked AT&T Focus, when I'm using indosat (IM3) carrier, I'm having this issue. I downloaded Network Profile from Samsung Zone. After reboot the device, the network profile still pick AT&T, and I can't change it to my carrier.
Then I tried change my carrier to 3, after reboot the phone, the network profile changed to 3 INA. And after that I haven't got that issue till now.
Not sure what caused this. But when I looked at the registry there's a bunch of duplicated APN settings.
I had a similar issue, Focus AT&T on EU network.
Chevron unlocked and enabled the 3G toggle.
From time to time, I couldn't download from Marketplace or use the 3G connection. That was before I updated to NoDo. I haven't experienced this again since I updated.
To fix that, I used to toggle 3G off and on again after 15-30 seconds.
Sometimes, even that didn't work and I had to leave 3G off. Any lower data connection was working while 3G wasn't.
Speaking of data connection, not everyone is aware that after updating to NoDo, HSUPA is disabled on AT&T.
I'm having the same issue.
I´m using an unlocked at&t samsung focus at my local carrier.
I have this issue a few times a day, and the only way to restore my internet connection is rebooting.
I have noticed that this happens when my phone changes to Edge and goes back to 3G again. The issue doesn't seems to happen every time, but sometimes I lost connection.
Did you managed to solve this?
Same here
Using it with mtvmobile italy
Have to reboot everytime
I was having the same issue, being unable to connect to 3G. Just go the first page after Googling: set att apn. AT&T users should put in the APN, username and password. Hope it helps! It worked for me. =D
I´ve the same problem, here at Costa Rica with my focus which is not unlocked nor jailbroken

Did you solve this problem, I'm in Costa Rica but have issues with 3G connection... :-(
Hi guys,
I have a problem with the 3G connection on my phone. If I have wi-fi active, 3G doesn't work. If I turn off wi-fi and enable data connection, it still doesn't work (the 3G icon shows up next to the signal icon, but no internet). I have to restart the phone in order for the internet to work (a 3G+ icon shows up, or E, depending on the signal strength). And this method doesn't always work, sometimes I have to restart the phone 2-3 times.
I tried an app (Repair 3G), but it doesn't seem to do anything useful.
Also, I don't know if it matters, but there's no custom rom on the phone, only official updates. For unlocking, I used some website that I found here, I just visited the site from the phone, clicked a button and the phone was unlocked (at least I can install xap's from the PC).
Can someone help me with this?
Thanks!
You can try "Network Profile".
Choose another Profile and than back to yours .
If your profile is not listed in profile manager try some other which is listed for your country (which might use the same network as your provider).
Keep in mind that your IE favorites are also reset when switching profile. At least that's what I noticed.
Hello all,
I have resorted to posting here as i have trawled the web for a solution without any luck. Here is my problem hope you can help.
I have a nexus 4 and am currently in Spain. After traveling abroad and not using data roaming i came back to Spain to no mobile data connection. The usual tricks of restarting, toggling mobile data airplane mode didn't work. It was quite frustrating. I went as far as to cancel my contract and go for a prepaid card - Lebara as they have a decent data tariff - but the problem persisted. I have configured the APN, gone through all the restart procedures, even factory reset the phone twice and nothing helped.
Mobile data is switched on. I have the APN set up as needed. However, the H E H+ never appear next to the bars on top no matter what i do. I have ordered another SIM card from a different operator in desperation but it might not be here for another week.
I really hope it is not the phone but now I really don't know. I am taking suggestions...
Thanks
PS one thing I just noticed is that if I download apps from my browser the device is listed as vodafone nexus 4 although I have never been on vodafone. This might have some relevance

Go to the dialer, press*#*#4636#*#* this brings you into new menu. go to the phone information to see to what network you are connected. if you scroll down you can force the phone to use 3g (WCDMA only) see if this work. this seting will change when the phone goes into reboot.
also if you happen to have the "3g bug" connecting to a wlan might help as stated by some users.
For me starting the hot spot function does the trick.

Thanks for the advice endet. I have done this but to no avail. When I switch to WCDMA only in the field GPRS service it says connecting for about a minute and then disconnected. After restart it is directly disconnected. I have toggled between GSM only and WCDMA only and restarted the radio. Played with the other settings in this screen and nothing. Only once did I get brief flash of the H on top but trying to replicate the steps didn't lead to anything.
Starting tethering didn't help either...
Could be something with my IMEI? Or CellInfoListRate?
Hi all
The past 2 days I seem to be having an issue with intermittent 4G coverage...
It will connect to 4G but have a small X next to it in the top menu. I receive no internet however.
What does the X mean as I can't find the answer anywhere, and is it an issue with my phone or my service provider?
I am on EE UK and running 7.1.1 Beta NPF10C
I have restarted, turned on and off airplane mode, reset my APN to no avail.
Anything else you need to need to know I will provide
Thanks in advance
I have had the same problems occasionally & I think it's an EE fault. It basically means you have a 4G connection but no internet access. Toggling mobile data off, waiting a minute or two, and re-enabling seems to get a new connection.
