[Q] Flashing different modem - Galaxy Tab Q&A, Help & Troubleshooting

Hi guys just a quick question.
​I have a Telstra SGT from Australia and I'm currently travelling around the US and want to buy a T mobile sim to use the 4g network while I'm here. I would like to flash the T Mobile modem during the overcome flashing process but I'm just wondering if this is possible or if it will cause any problems for my tab?

You will only get 2g/EDGE at best. The tab is only a 3g radio. Your tab won't be able to get 3g though because your tab is not comatible with t-mobile 1700/2100 bands.
You can buy an at&t sim and get 3g and voice.

Thanks so much for your help rangercaptain. I was unsure about the tab's bands and was hoping it was the same as the T Mobile ones. Oh well, I guess I'll just stick with AT&T. Thanks again for your kind assistance!

Tmo Tab over At&t tab?

Hey everyone,
Just wondering if there any big difference between between the Tmobile and AT&T samsung tab?
Does one have better features or better pre-loaded apps? Are both easily rootable? If so, which is better?
The only internal hardware difference is that the T-Mobile tab supports the T-Mobile 3G bands whereas the ATT tab supports ATT bands. Also, the ATT tab will be better if you were to travel a lot in Europe as it can support European 3G frequencies.
There are also some changes in design on the back of the tab (mostly in regards to color). As for preinstalled apps, I an unsure as I do not own a T-Mobile tab.

The T-Mobile one will work with T-Mobiles faster 3G HSPA+ network. Not at 4G though, just faster than 3G. However, this it not available everywhere.
In the EU, the T-Mobile version will only support Edge, whereas the AT&T version will support 3G.
The most important piece is AT&T version could be used as a phone w Euro firmware and an existing AT&T SIM card. Sounded like you're not an AT&T user but it's doable.
For Tmob tab, you could also set it up as a phone but you will need a data plan then setup GV+IPKall+SIPDroid if you don't want to pay for Skype.

It can?
I know it wont wont in the UK, as their 3G frequency is 2100 and i believe the T-Mobile tab uses a different frequency for uploads vs downloads (1700 and 2100).

It will work in the UK.
Read the specs. Follow the link, and click on specs.
The TMo US Tab supports:
850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (AWS);UMTS: Band IV (1700/2100)

I got the specs from Samsung's website, they are posted as:
GSM: 850, 900, 1800, 1900; UMTS : Band IV(1700), I(2100) & Wi-Fi
I read the UMTS bands as the AWS 1700/2100, (1700Mhz u/l; 2100Mhz d/l) not AWS(1700/2100) and UMTS 2100 (so only able to download on the 2100, not upload on this frequency).
It does seem a little unclear, but if it really does support 2100Mhz upload and download, that would be awesome!! Would also mean you could unlock it and put a 3G AT&T Sim in it...
Anyone know this for sure?

Trust me, it's fine.
Band IV is AWS and completely separate from Band I. Even the Samsung website explicitly mentions the bands it supports. European 3G uses Band I so it will work.

That is awesome.. The only thing, other than cost, holding me back was that it might not work in the UK.
Now I just have to convince myself that i will get $350 + monthly data use out of it. Price, though expensive, is not really an issue but if I bought it and didn't use it, i would get into trouble from the missus.... :s
Flash T-Mobile Tab to support AT&T Voice
FYI - I followed Rotohammer's directions and i flashed a T-Mobile Tab, then unlocked it, and after I inserted my AT&T sim, I had phone and Edge:
http://forum.xda-developers.com/showthread.php?t=886714
However, I'm trying to figure out if I can load a new modem and get AT&T 3G on this tab (bought from T-Mobile)? I tried the bell modem but it didn't work. Am I safe to assume that the T-Mobile hardware will support AT&T 3G and I only need to find the right software?
Thanks - these forums are great... Sorry if this is the wrong spot.

Don't waste your time and or brick your Tab. Tmo Tab will never get 3G on an ATT sim card because it doesn't do 3G on 850/1900mhz band. Hardware doesn't support ATT's 3G bands.

I understand the feeling. I initially went with the Tmobile version but at a data rate coming up to almost $70 after taxes ($59.99 unlimited data for not having my phone with Tmobile), I took it back, paid the $10 restocking fee and went with the at&t version. After roto's rom to enable phone i just plop in my existing unlimited (grandfathered) at&t sim and i'm golden.
Either way I did the analysis....and i believe it was after like 8 months the AT&T version comes out cheaper and if i recall that was WITH the 2GB data plan included.

Tmo does not have a $59.99 data-only plan. It's $39.99 for 5GB, after which you're throttled past the 5GB allotment. No overages.
But i prefer AT&T's $24.99 2GB plan (don't need calling, already have a phone). The price is just right. Still looking to trade my Tmo Tab for an ATT one...
Yup caught me off guard. The the tmo salesman explained it to me instore. If or when I take my phone with tmo I will get a $10 discount on the data plan. Fishy but whatever, I was never a t-mobile customer so I just went along with it but yes normally its 39.99
Bumping this as I was going to get a WiFi only TAB but with its inferior hardware I'm looking at a 3G TAB.
On Amazon the Tmobile version is a lot cheaper at $475 than the AT&T version at $550, not sure why?
Anyway I'll be using it in Europe so it seems the Tmobile version would do the trick with its 2100Mhz frequency?

The AT&T version has always been more expensive...just the way it's been priced I guess. If your only or mainly going to be using it in Europe you will be fine with the T-Mobile version as it will run 3G on 900/2100 over there
If you're keen on digging around with different roms and are comfortable flashing around then go for it. But if you're looking for a smooth out of the box experience off the bat (with calling etc enable) I'd wait and pick up one over there....just my 2 cents

Will a T-mobile Nexus one work on Bell Mobility (Canada) network

Is it possible to get a T-mobile N1 to support the 3G Bands 850/1900 that the bell network supports? I know it is possible to flash different radios with android phones. I am still a fairly new user to android but i'am trying to learn and u can't learn with out asking questions
Thanks,
Ryan
You won't get 3G. You need the AT&T version for Telus/Bell/Rogers. You could try Wind or Mobilicity.
well that sucks, neither of those are in Nova Scotia where i am located
You could always try to look for someone to trade with, AT&T for Tmobile Nexus.
But it would probably be hard to do in person if there is no demand for it in Nova Scotia.
I don't know how safe it would be to trade by mail.
Any plans that Wind or Mobilicity will come to Nova Scotia? Just curious.
You could get it to work on Rogers GSM network but you won't get 3G, I could be wrong but I don't think Bell or Telus have GSM networks so you're out of luck there.
Oh yeah, there is that little snafu too. Even worse.
It will work on Rogers but you won't get 3G speeds.
It won't work at all on Bell/Telus.

So are you saying his Tmobile won't work on Bell/Telus at all?
But an AT&T will work fine on Telus, with 3G as well?
I am considering buying a nexus one for when I switch to telus next month.
Yes, the T-Mobile version will only work on Rogers/Fido with 2G only.
It will not work on Bell/Telus at all, ever.
It will only work on 3G on Wind Mobile and Mobilicity.
If you want full Rogers/Telus/Bell support, you need the AT&T version.

If you're a Canadian and you want a "Nexus One-like" experience on Bell/Telus/Rogers, and you're having trouble finding one with the right 3G bands...
Get an HTC Desire from Telus. Problem solved. If you don't like Sense UI you can flash it with all sorts of ROMs that will make it feel more like an N1, or you can put MIUI on it, or Cyanogen, etc...
Or according to mobile syrup(can't link) the nexus S will be on the big 3 in march

[Q] getting ATT 3G to work on US TMobile Tab

I have a US T-mobile Galaxy Tab which was officially unlocked by T-Mobile.
I took a data plan with ATT, but I am only getting Edge, no 3G
Doing some research I read that T-Mobile uses a different 3G than ATT therefore the issue I guess.
My question: Is there a way to configure the T-Mobile Tab so that it can Connect to ATT 3G or is there a Hardware impossibility?
Apreciate the help

Hardware limited, unfortunately. T-Mobile uses 1700mhz, whereas AT&T uses 850mhz and 1900mhz for 3G
Sent from my GT-P1000T using XDA Premium App
Thanks, its a bummer as their data plans are more interesting for me ...
May be if they merge they will straighten things out in the plans. One can dream
Look in the dev section, rotohammer has a modem switcher, which gives 2G+voice or just 3G alone.
There is a bounty searching for a cook to work on the modem.bin for us, but no takers.
Look at the Dev section or get an ATT Mobile Hotspot and share the conection thru wi-fi to the tab, the only bad side of doing that is that you can't use Gps navegation
Thanks all.
Dont realy want to go the custom rom yet as I may not keep the tab (waiting for newer models).
So I'll see how good or bad it is on ATT Edge, and switch to Tmobile 3G if it is really bad.

I thought that the SGT used software defined radio (baseband) for it's cellular modem and therefor isn't it possible to flash the at&t modem.bin onto the SGT and take advantage of at&t's 3g services (with the appropriate frequencies)?

nope, which is why I thought the AT&T Gtab to be the most desireable, as it can do AT&T 3G plans, but also take advantage of Tmo's $1.49/day DayPass (EDGE only). The Tmo Gtab cannot use the DayPass (Tmo has locked it out).

[Q] Unlocked galaxy note on Cincinnati Bell apn issues

Hi all, I am having trouble getting my unlocked note that I bought from amazon working on my Cincinnati bell network. I have voice but after searching the internet I tried a few different apn settings but can only seem to get the 2g edge network and not 3g let alone 4g. Any help would be greatly appreciated
i believe 2g is all you will get. cincinnati bell runs 1700/2100 3/4g and your note uses 850/1900. same problem as tmobile usa except the few western states using the 1900 for 3/4g.....
Jesus, how can a country that influent be so totally retarded when it comes to getting a mobile phone to work across the entire country? There's like a million standards and not even the same within a single operator. Get with the times - heard about GSM/WCDMA you know that the rest of the entire would uses?
Sent from my superior GT-N7000 using Tapatalk
Thanks, I heard T-Mobile runs the same network as Cincinnati Bell, would their galaxy s II work then?
tmous branded "should" work.. uses the same freq...
You can get more than 2G. CB has their own 3G network but you have to go to the store and upgrade your SIM card

That does not seem to be the point here... The point is that it seems Cincinnati Bell uses frequencies that are NOT compatible with the N7000 being the 1700/2100 band as opposed to the 850/1900 band that the N7000 uses.

[Q] HSPA+ on T-Mobile

Hi, if I were to get an unlocked Galaxy Note GSM, would I have to do anything fancy to get HSPA+ (4G) to work on it?
Would it be as easy as to pop in my SIM card and go to work like on any T-Mobile device?
Please respond back soon because I am trying to buy one tonight off a guy on craigslist, I don't want to get ripped off!

then you'll need to wait until T-Mobile repurposes their 1900MHz band for HSPA+. I don't know if they're doing it for the whole country, but it has started to happen in some areas already

Sorry but don't count on anything more the edge on TMobile, unless you are really lucky and you are in a 1900 Mhz area. If you want TMobile buy an AT&T Note and you will have to do some hacking to get the radio working on TMobile.

Don't expect the entire US to get 1900Mhz 3G on tmobile, since the radio spectrum is subdivided differently depending on the cities.

So there's no such hack for the international note? I don't understand how an internationally unlocked phone doesn't support USA GSM highspeed. My T-Mobile G1 supports HSPA+.
Does AT&T 4G work with the international Note? I have it now and I'm only getting 2G. It's god awfully slow.

I'm on the Left Coast, maybe should l see if 1900Mhz is in my area.
To be honest, I'm actually happy with me my broadband sim on AT&T. I just had the LTE code added to my account and I got a little boost in speed on HSPA+. I'm seeing 8Mbps down and the speed seems more stable then before. It does seem to be ramping up to max speed a little slower and I have a firm upload cap at about 1Mbps, before I occasionally would hit 1.5 Mbps. HSPA+ does seem to do Skype and Google Voice pretty well, I've been managing to use a a data sim as a phone quite successfully.

The international Note gets HSPA+ on the AT&T no problem. I'm currently enjoying my H+ icon with my Red Pocket sim card.
The International and American Notes have entirely different hardware inside. The American Note has a pentaband radio that can be reflashed for either AT&T or T-Mobile frequencies. The International note does not.

Wrong. The International Note has a pentaband radio. It's the same modem as the Galaxy Nexus GSM.
It just so happens that the AT&T Note shares the almost the same hardware with the T-Mobile S2 which makes it easier in terms of getting the modem from the T-Mobile S2 to work on the AT&T Note. This is why how they got the hack working on the AT&T Note.
This DOES NOT WORK on the Int Galaxy Note as we are running an Exynos/Infineon chip/baseband.
Okay. Instead of arguing with each other about who can spout-off the N7000's and i717's specs most accurately, why don't we just give the OP a simple, comprehensive answer?
Okay. To answer your question, the N7000 (International Note) will work perfectly fine on T-Mobile US. Phone calls, SMS messages, and data will all work perfectly. The issue, however, is not with the services you can get, but the quality of the services you can get. Even though the N7000 is an "international" GSM device, T-Mobile uses irregular frequencies for it's HSPA+ network. Specifically, instead of supporting HSPA+ on a single frequency, T-Mobile's HSPA+ service is divided between 1700MHz and 2100MHz in what is referred to as 1700/2100 AWS (Advanced Wireless Spectrum). Because AWS is a rare and unusual implementation of HSPA+, almost no "international" phone models support it. In most cases, only phones meant specifically for North America support it. What this means, simply, is that the N7000 will never be capable of using T-Mobile's HSPA+ network (unless you have the rare privelege of being in a 1900MHz HSPA+ area).
Now, just because the N7000 won't let you use T-Mobile's AWS HSPA+, it doesn't mean you can't have your cake and eat it too. Granted, it is a small concession, but the i717 is a "more than adequate" smartphone and will (with some minor modification) make neat work of connecting to T-Mobile's AWS HSPA+ network. Preliminary speed tests even suggest that the i717 is faster on T-Mobile's HSPA+ network than the N7000 is on AT&T's HSPA+ network. So, if you're willing to sacrifice the added speed and power the Exynos SoC offers, you could gain T-Mobile 3G compatibility and NFC to boot just by opting for the i717; which, I might add, is only $649.99 off-contract at AT&T.
If I can help clarify any confusion or answer any questions, please feel free to ask. I know there are a lot of people out there who feel very strongly about which version of the Note is superior. However, it's my opinion that when you come across someone who's undecided, you should simply give them the facts and allow them to make their own decision. Passionately mixing facts with opinion only serves to further confuse things.
