No 3G - Bell Galaxy Tab with Rogers SIM card

Hello all,
I am using a Bell Canada GT on Rogers in Canada (with JPZ modem).
All works good (I have internet and phone) - however I never seem to use 3G.
The 3G indicator comes on for a second or two, but then the GT switches over to a non 3G data mode.
I would think 3G is the fastest - and it would be great to use it.
Do I need to use a different modem file? Or maybe different settings?
Please help.
Thank you all!

What is it switching to? H, or G, or EDGE? There is a Bell modem - JK3. Maybe try that? Takes only a few seconds to find out.

It switches to H

H is a half-step faster than 3g. It's short for HSPA (high speed sumpin-sumpin).

Thank you so much for explaining. I googled hspa and you are right. I have learnt something from you.
Also, it seems then that there is no need to touch the modem file.
Thanks again!

I wouldn't change it - it sounds like you get good results.

[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.

i9000 cannot make or receive calls. modem problem?

Hi everyone, noob here so dun wanna start a new thread with my question since it is related to this matter and I was wondering if anyone can help me because I really can't figure it out anymore.
I have an International GT-i9000 purchased with Hong Kong and system specs I have running are
Gingerbread.ZSJW4 (recently flashed the official ROM from Hong Kong cuz I am anal and want to keep the same languages)
Kernal: 2.6.35.7-I9000ZSJW4-CL1147074
[email protected] #2
Bandbase version: i9000ugkg3
And I use AT&T in New York (I know, worse plan to use in dead zone capital of the US)
I had flashed the ugkg3 modem on it because the JW1 modem that was with the official ROM wasn't working out for me and I had heard this modem was the best for my area. Before it would either not pick up a signal when coming up from underground or the signal just go dead, which did not happen when my phone was on Froyo (on Froyo I did not have 850mhz enabled and it worked alright outside and sometimes in the house)
At first, the KG3 modem worked wonderfully, I was able to receive data in my house and was on 3 bars (compared to none to one before). However, I now notice that while I do have full bars, I cannot receive or send messages or phone calls (even though my brother's Note is able to do all that and it was next to my phone).
I also happens when I am outside as well.
The other day I was standing in front of the AT&T store near where I am and I still don't pick up a signal.
Or it would lose the signal and never pick it up again.
Unless if I really can't use 850mhz on my phone, which does not make sense because AT&T uses 850mhz.
I am real hesistant to try another modem, and I cannot figure out if it is a hardware issue or network issue, or is it just the wrong modem?
Can someone please share any insight?

[Q] slow mobile data connection

Hi, I have problems with my mobile data connection. It shows 3G or even H connection but it is very slow.I tested the speed with an app and I get max 192kilo bits per second with H and E connection.
I use on my I9001 SlimBean 4.2.2 build 7.8 with Kernel 3.0.89-K^Kernel JB4.2.2 OV UV 360.
I tried three different Basebands XXKQP, XXKP4 and XXKPM.
I'm in the US and my cell phone provider is simplemobile which uses the T-Mobile network.
I use theAPN settings which my cell phone provider suggests.
At the beginning I used my phone with the stock rom 2.3.6 and evything was fine.
After flashing to custom rom I got this issues.
Have anybody an idea how I can fix the problem?

maybe flash a different modem see if that helps

I thought base and is the modem driver? Are there More basebands then in the i9001 wiki page?

Try XXKPO-Baseband. It works fine for me. If that doesn't help, your provider could also be the problem. Can you take the sim-card of a friend or family member who has an other provider than you and try if this solves your problem?
Sent from my GT-I9001 using xda app-developers app

I tried XXKPO-Baseband but the fastest download was 120 kilo bits per second even with 3G.
The thing is, everything was fine before I flashed to the custom rom.
I will try a stock rom and will report if I fixed my issue.

Have you tested an other custom ROM, for example CM? Maybe it is a prob of SlimBean ==> have you written this problem in the development-thread?

Depending on your area, built up? middle of nowhere?
These are things you need to tell people
Try any of these 2 : ZSJPG or BUJP5
I use ZS as I stay in the UK and gives excellent battery as well as signal strength
Hope it helps :laugh:

I tried also liquid smooth and a stock rom. But the data connection is still slow.
I tried a t-mobile prepaid card which uses the same network as simplemobile and I got 3500 kbits.
So called my provider three times but they could fix the problem.
The last guy told me that my phone won`t work with simple mobile. But it worked with 3G and H in the past ...
And every time I test my speed it has 120 kbits. Seems to me they throttled my speed.
Where can I get ZSJPG or BUJP5?

Maybe a stupid question:
Is your Internet data consumed and your Internet is because of this throttled...???

OK, before trying these modems are your APN settings set up correctly for your network provider?
LINK TO MODEMS HERE

OK, I called the support service line three times.
Yes, my APN settings are correct. My plan has 500 MB 4G then "only" 3G but "unlimited" what ever that means!
I think the best way is to change the provider ...

Or trying another modem first only AS a test...
The idea the others had...

WCDMA basically reffers to 3g
are you confirmed that the 3g service that you wanna use works in your area
you should confirm this by asking about this to the network provider through customer care
if that 3g service is not available in your area then you cant get signals in WCDMA mode

...?
So you are using WIFI, have you contracted a data rate on your mobile?

Where do you live? There might be some issues with different WCDMA signals in countries

As long as it is the firmware for the model (S5830 firmware->S5830, nothing else), there should be no problems.
