[Q] Slow 3G - Xperia Z Q&A, Help & Troubleshooting

Hey guys!
Got a question on internet/browsing performance.
I've got a C6602, and no matter what i do (rom change, internet optimizations....) the 3G data connections lags from reaaaaallllly Slloooowwww to Not working at all.
HSPA and HSPA+ speeds/connections work fine. It's only when the phone reverts to 3G or 2G that internet connection Lags.
Any one experienced this problem and does anyone know the fix?

[02 2g/3g] losing 3g signal and does not fall back to 2g/edge?

Hi Guys
well did a search and couldn't find a topic about this, however if there is Sorry.
Anyways got my 02-Uk simplicity yesterday and set 3g and MMS up all fine, and was working fine, however today I came to work which is a bit out in the sticks so hard to get a 3g signal, and because of this i noticed I lost all signal.
after playing around I noticed that switiching it to "2g networks" i managed to get a full edge connection. My question is how come if it loses the 3g connection does it not revert back to a 2g network? I know there is a 2g connection beacuse if i do it manually it works. is there a way to do it automaticly?
also i do have data roaming connection active, and can post my APN details if anyone thinks that will help reslove the issue.
Thanks
matt
Brought mine in to t-mobile to ask the same question. they said just stick to 2g only when you're not in a known 3g area. They also recommended just turning data roaming off
I have the same problem with my Goophone Y6.
2 solutions I know:
1) Flightmode on/off
2) Reboot
This is very anoying, because the bug apperas again. One question: Do you lose signal when you turn your display off or after approximately 5 minutes?

[Q] Only using 3g connection on hd7

hi everyone ,i'm a new user .
as title i make this question.i often connect to internet by 3g connection.i went to setting/mobile network then i set data connection: on,3g connection: on and my country APN.My Hd7 work well ,but only "use 3g connection when availale". it almost switch to 2g network
Anybody have ideas to solve it ?it really really necessary for me
Sorry for my bad English,hope you understand my problem
Go to the dialer. Type ##3282#. Go to settings, under 'Network Type', choose 3G only. If it's already on 3G only (I think it moves back and forth between 2G only and 3G only while on Automatic mode), change it to 2G only, then back to 3G only. This will keep it on 3G only.
thank you very much.i solved it
hello friends I have a t-mobile hd7 but I'm from Colombia, they know how I can make it work on 3G network here in Colombia because it only works on 2g

[Q] 3G Problem with HO! NO! 7.1.5 ICS Edition.

Hi Guys,
I have been having a problem with Ho! No! ROM. I am in India on AIRTEL 3G. Whenever I switch to 2G Network I tend to loose signal and after sometime the signal gets completely lost (EMERGENCY CALLS ONLY is shown). If I remain in 3G only, everything works fine but battery usage is obviously more. Moreover, recently after HO! NO! CM 7.1.3 I am not getting 3G speeds while internet browsing while being on 3G network.
My Mobile Network Settings are like:
Data Enabled: On
International Data Roaming: On
National Data Roaming: Off
Network Mode: GSM/WCDMA(auto mode)
Use only 2G Networks: Off
Do I need to change my radio/baseband according to India (where to find the same and how to do it?)
I didn't have any such problems on CM 7!!!
Please help me out guys!!!

I used MiniMod to switch my base band and now the 2G Signal loss problem is solved. But internet speed is still all messed up on both 2G and 3G. It seems like that this is a problem with HO! NO! ROM rather than base band as my internet browsing was working flawlessly on earlier HO! NO! ROMs without switching the base band.

Rarely got HSDPA connection

Hello guys. Been using my BS for nearly a month. but i had noticed something strange, that is whenever im on data connection idle, it shows H as in HSDPA connection. but as soon as i load a page using opera mini, or any other apps that needs data connection, the H indicator changes to 3G.. and the page was loaded somewhat slow because it was on UMTS (3G) connection only. Im running Maximus HD rom 3.0.. and this problem also exist on stock rom. It is not my carrier fault because as i insert the sim card into my note 2, it can load page and surf the net on HSDPA connection.
is there any possible fix for my probs. thanks.

im on 4.1 and noticed it wasn't wanting to ring or text or connect to data on 2g but will on 3g
so I tried 4.3 didn't make a difference
what could be causing it not to work on 2g signal im using o2 uk I no spare sims to try another network
some strange reason if bars on 2g less then 3 it wont work could this be a issue with the antenna
