No 3G - Bell Galaxy Tab with Rogers SIM card - Galaxy Tab Q&A, Help & Troubleshooting

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] Ridiculously slow internet

Hey peeps,
I have a SGS i9000 connected to Rogers Wireless. I'm running Doc's ROM v7.
I have very very slow wireless internet (3G, if thats what im connected to). I used SpeedTest.net and my downloads are at 33 Kilobits/s... so yeah very slow. I've called Rogers and they said its because I have an unlocked phone?? That is doesn't garuntee that 3G will work but isn't this speed slow for 2G/Edge?
If anyone can help that would be great as im stuck on a 500MB plan with them and I feel like I'm getting no help from them.
It due to reception. I'm on rogers with i9000 as well. Try it at a different location also check if you have 850 band enabled. Places like york dale mall I come to a halt but at work I'm fine.
Sent from my GT-I9000 using XDA App
I will check other areas, but its wierd because I live right downtown in my city and can see more than 3 towers. How do I check that my 850 band is enabled?
Alright so I checked my bands and all are selected.
In the Status bar is a G with up and down arrows, ive read that that means im connected but in GPRS... not even Edge!

No 3G data on Rogers, with overcome ROM

I actually didn't notice at first(since 3g is patchy where I live) but since switching to the overcome rom my tab will connect to 3g but as soon as data transferring begins/resumes it will switch back to "H" which is thier high speed "Edge" network.
Baseband version: I9000UGJK3
Could this be the at&t modem that overcome provides?
Are there any other modems I could test out that might be better?
Thanks for your help.
found what i was looking for here
My toolbar still shows "H" during data transfers ("3G" otherwise) but the speeds seem fine, so I'm not sure what the issue is with that.
H is HSDPA which is faster 3G. http://en.wikipedia.org/wiki/HSDPA
Ok that makes more sense, thanks.
Speeds seem to be the same with the jm2 modem, anybody else done testing on the rogers network?

[Q] Galaxy tab 7" not getting tomibile 3g

Hello,
I have a galaxy tab non branded with overcome installed.. I`m trying to get Tmobile 3g on the tab but no matter what modem i installed i`m always getting edge.. I tried with roto modem switch.. but still no 3g.. Tried to flash with tmobile stock modem but no 3g..
Model number GT-p1000M (SGHI987)
Firmware 2.3.6
Baseband T849UVjjB_ROTO-3G (after useing roto modem switcher)
Kernerll 2.6.35.7
Overcome-v4
I have tried the froyo, gingerbread now trying it to get 3g on overcome..
Please suggest me if i have to make any other changes to get 3g on tmobile network..
Thanks
bell mobility tab no 3g on tmobile
No one is having this issue ?
No 3g, just Edge signal
I too have a similar problem with no 3g signal. I'm in Bolivia and I have 3g coverage with my provider. I had upgraded to Gingerbread in hopes this would solve the problem. No 3g. I then installed the different modems and I still had the same (no 3g) problem. After this didn't work I went back to Froyo as a last ditch attempt since I had rooted Froyo in the beginning and thought maybe something got messed up. I've never seen a 3g signal here and don't know about the U.S since I've only use it here. Is it possible that the Galaxy Tab 7 3g just does not work in Bolivia? By the way, I've checked all settings and done everything to make sure things are correct. Any ideas? Thanks.
for @polapine, this is answered in another thread.
Basically the conclusion is that T-mobile uses different frequency for 3G/HSDPA, that a normal unbranded tab modem hardware is simply incapable of using. (1700 Mhz)
On the other hand, a T-Mobile branded tab can also operate at the "usual" 3G band in other networks in Europe/Asia/Australia (2100 MHz)

[Q] Data on Rogers network

Edit: not sure if this is a switching problem or the way the phone is designed, but sort of figured it out...seems that the Exhibit 4G will auto fallback to UMTS when no HSDPA link is active. Just ran some speed tests and it did in fact hold HSDPA speeds, when done it fell back to UMTS. My GS3 doesn't do this...if I have 4G/ LTE available, it stays with it. Hence the confusion.
I recently purchased a new unlocked Exhibit 4G, have been testing the various roms here...many thanks to the devs...great work! Currently trying AOIP...nice!
My primary usage is on the TMO network, at my RV site on weekends. Unfortunately, 2G is the best I can get in my location, regardless of carrier.
I live in Canada the rest of the time, on Rogers with a GS3.
I was testing out the Exhibit 4G with my Rogers sim, LTE APN's were set up ok, voice & messaging are fine, but data is wonky...I will get the 'H' (aka 4G) icon for a few seconds at a time, but for some reason I keep falling back to 3G speeds. This cycle continues over and over. AFAIK, this phone should support Rogers HPSA+ frequencies (aside from their new 2600), shouldn't it?
So I'm wondering if this is due to an incompatibility with the phone on Rogers, or needing a different baseband, or could the phone's h/w be screwy? This has been happening with all roms I have tried (AOIP, Baked, Slim).
Appreciate any insight.

[Radio] Unnecessary fallback to Edge from LTE. Help needed.

Hey Guys,
I really hope you can help me here.
Some days ago I changed my contract from O2 Germany to Vodafone (which is supposed to have a good LTE coverage here). Anyhow my mobile reverts from 4G/3G most times to EDGE and I don't understand the reasons.
I tried via the hidden code menu to force wcdma preferred or LTE only and I have stable LTE connection. It isn't very fast (2-6Mbps) but at least way faster than edge.
Now the question. Why does my mobile revert to edge? And can I save the setting for wcdma preferred for reboots. Right now as soon as I reboot the mobile will again connect to edge.
I really hope someone of you's got an answer.
Baseband is: MPSS.TH.2.0.c1.9-00102-M8996FAAAANAZM-1.88834.1.89286.1
Thx

Whilst i'm in the UK and not Germany, since the unified builds (e.g works on the 3 & 3T), i have noticed this too. 4G is super fast, like 100mbit down in some areas but 99% of the time it will drop to 3G (my network doesnt support 2G). If i use a copy of LineageOS, i'm totally fine and have 4G in 99% of places.
