Tmobile 3G on International Edition (GT-P1000)

I am testing the International Edition of the Samsing Tab (GT-P1000, with the phone functionality built in out-of-the-box and the white backplate). Here in the US, when I insert an AT&T SIM card I get 3G speeds (peaked at 6 MB downstream recently), but when I insert a Tmobile SIM card I seem to only get EDGE speeds (not 3G, around 0.1 MB downstream). The Tmobile SIM card works at 3G speeds on another phone, so I know it's not he SIM card. I can get voice calls on both Tmobile and AT&T with no problem.
Does the International Edition (GT-P1000) have the US 3G Tmobile bands?
Any input is welcome, thanks.

Welcome to the fray. Grab a beer and get comfy... because the Euro version does not play with TMobile's 3G network in the US.
If you are technically inclined, it seems we could use some more hands trying to figure out a fix for this issue.

The T-Mobile Tab does not have the hardware to support European 3G bands... That's why I believe the euro firmware people are flashing only works for voice/edge on T-Mob...

That would make sense that the International (Euro) version does not have US Tmobile 3G bands... it makes me wonder if the limitation is in the hardware or software.
Do we have any indication that the limitation is in the software, other than the fact that a US Tmobile version exists?

I am certainly no authority on any of this, but this looks to be incorrect. From my reading of the posts on this issue... the Euro version of the Tab (specifically, its modem.bin file) isn't set to work with TMobile's 3G network as the that network operates on a frequency that isn't used in Europe.
User rotohammer looks to have the most knowledge on what it is going to take to make this happen -- but keep in mind that most of us have TMobile Tabs and are needing a solution with that fact in mind. The general thought was that we could use the firmware from a Euro version to give us voice-calling capability, and then hack-in support for TMobile's 3G network.
sheesh, I wish I would have paid attention in school because I want to be a bit more useful with all of this.

According to what I have figured Out....it disappointed me too, But!!
GT-P1000 is not capable of running 3G Tmobile network
The Hardware CPU, Radio Chip...is capable and is switchable to the band of 1700/2100 MHZ.
The Radio Amplifier is not Capable of 1700/2100 MHZ bands....so us who have International Version of the Tab is Screwed!!!
The proof = I flashed my GT-P1000 using Tmobile Modem to switch and ENABLE 1700/2100....I can only have Edge+Voice...when I flash to T849 modem....the Tab gives No Signal
if the GT-P1000 was capable of handling 1700/2100 Bands easily then my Tab should do 3G only by using T849 TMobile Tab modem Bin
I am a google nooby and is doing what I could....those are what I found out...seem like I have to sell my GT-p1000 Soon.

This is the only way...yeah...wait til TMobile release Phone + data on tab...or switch to ATT
The international version and the ATT tab is about the same....the 1700 mhz band is shot out.....
Samsung exclusively included 1700 for US tmobile just as they exclusively make cdma tab for the sprint and verizon.......
No hope....m selling mine, or return to the place i bought from and lose 200 usd
****If buying this tab for phone call and edge only***** I rather go for the Ipad 2 or Iphone 5 in a few months
US tmobile have a unique stupid bands on their 3G....and all of the phones or tabs they have suck monkey *****....

Hi everyone I was reading Motohammers post in the developers form about being able to get 3G on a GT-P1000.
My question is this... It's my friends tab and I am not able to get 3G at all. He doesn't care about being able to use the phone, but would like to use 3G data if he is out of wifi.
info in the tab:
firmware= 2.2
baseband= P1000XXJHA
Kernel ver= 2.6.32.9
[email protected] #1
build number= FROYO.XXJMA
I followed Rotohammers T-Mobile Modem Switcher, but am getting
stderr: Unable to chmod /data/local/tmp/
redbend_ua: No such file or directory
stderr: /data/local/tmp/redbend_ua: not found
I followed the directions exactly and still no go... followed another guys post to install files on the internal sd card and still can't get 3G to come up no matter what.
The SIM card I am using is from a Galaxy Captivate S with voice and Data (6gig plan) on Rogers....
Any ideas?
Thanks very much!
M.

@fishguyis
Have you tried flashing a Rogers modem? At the end of your post you say you are using a voice/data sim on Rogers, not sure if you have tried this or if it will even work but as far as I know if you flash a modem that doesn't work you just won't have a signal, and you can just flash back to a modem with signal, if you got the modem switcher working and you just don't get a signal or if you only get edge, most of the time you can rename another modem to match roto's modem name in the switcher and swap the modem you want to flash with the modem that roto includes with the switcher, like if you want to try a Rogers modem just rename it to match and swap with roto's included 3g modem, I hope that is not to confusing I can't think of any other way to explain it, I hope this helps in anyway and I hope you get it working.

hey what worked for me is i put the modemswitch folder into the INTERNAL memory[main folder] and i also put the switch.sh file into INTERNAL..
iono why it wasnt working on my external SD[got same errors as you] but once i did this...everything worked fine and i didnt get the error you got.
let me know if that helps you. as of right now my modemswitch folder is still located in my internal memory and i can switch back and forth easily.
edit- didnt see that u did this already. umm try to do it a few times. last night it wasnt switching for me.. so i charged the tab all the way up, switched my wifi off and did it again this morning and it switched for me..

Hey magnum,
I have tried at least 50+ times hitting the switch shortcut and i always get the same error...
I noticed in the post there was a problem with the switch.sh file from the OP but he said he fixed it... I re-downloaded the zip and tried everything again and still get the same error. ARGH getting frustrated LOL

idk, try to switch over to the overcome rom/kernel[if you haven't already] and try it that way if you want the 3g..
i must say the euro tab is nice and the 3g works good, i was video chatting earlier with no lag and even hit H speeds, not sure the big difference between 3g and H tho.
oh yeah my sim was from my tmo vibrant/g2 so it seems like we have the same set up, just dont understand why you are getting that error.
oh heres the info for my tab
model - gtp1000
firmware-2.2
baseband-t959tjl3 roto-2g
kernel version

I am not sure if this makes a difference but the GT is from Bell Mobility and if I go to "wireless/network", "mobile Networks", network mode, I get GSM/WCDMA (auto mode)
GSM only
WCDMA only
Does that mean there is no 3G available at all?
Thanks for your patience, I have been reading like crazy...

I think I may have a problem here....I flashed my Tab with the JJI latest firmware from Samfirmware....and I failed to reflash it to another PDA....I doubt that I could reflash everything to what u have now
What makes you have the 3G anyway ? is it the modem ? or is it the Rom ? Kernel

[Q] Which Tab best for Unlocking ?

I have been reading the unlocking / voice calling threads about the galaxy tab and they are really informative. However, with the thread growing so long and so many different carriers being discussed, I lose track of which version is doing what.
So, since I am buying one today, I would really like to know which carrier would be the best to unlock here in the US. Should I buy the AT&T or T-Mobile vesrion? Does unlocking or flashing one or the other provide better use or functionality than the other?
What are your thoughts?
Thanks,
JT

^from what i have read on here the tmo version is not compatible at the moment with the unlocks;
hence the at&t version is best in usa; and the bell canada version in CDA..
enjoy!

i would go with att because it will be compatible with Euro 3G frequencies also you will be able to hack to get phone calls AND 3g. I believe Tmobile is only getting voice and edge at the moment...

Because they are obviously more difficult to unlock and are probably less compatible with any other countries network. Almost every carrier worldwide uses GSM, sim cards. So version nor sprint wouldnt be a good choice since they don't use sim cards.

1. Both at&t and tmobiles tabs can be easily carrier (network) unlocked. Verizon and Sprint are CDMA and will not work in Europe. Also I am not sure that anybody knows how to switch these tabs from one carrier to another.
2. Another story about getting voice and 3G in the US. So far the best case for using tmobile phone sim presents at&t tab. Tmobile does not recognize this tab and their broadband device and allows for voice calling.
I could have voice and EDGE on tmobile using at&t tab with flashed EUR firmware and bell modem.

'I'm with Verizon's tab in SF, USA. Rooted with 4Zroot.
Using Droid X overclock application (market) on other extra features only.
GV & Skype (mod for 3G), can make calls & receives with both 3G (data plan $20-1Gb) & Wifi plane mode. I hope this helps.

I am new to all this and just want to be 100% clear.
If I have a TMob Tab I have to use an ATT sim. If I have a ATT Tab I can use either ATT or Tmob sim.
If I use the ATT Tab with my current Iphone 3gs sim (unlimited everything) I will have full voice and 3g function?
If I use the Tmobile Tab with my ATT sim (unlimited everything) I will full voice and only 2g data?
Im sorry for asking such a simple question but I just want to be sure before I buy a Tab today.
Thank you all in advance.

Att and tmobile are using different frequencies thus 3G won't work if you are not using sim and tab from the same carrier. You can get only EDGE.
Att tab allows for voice and data when using t-mobile sim with voice and data plan.
I don't have knowledge of whether t-mobile allows the same with att sim.

Thanks, that cleared it up for me.
I'd be happy with a TMob tab that had voice and Edge at this point. I'm almost always in WiFi anyway.
I picked up a Tmob tab today, if things dont look up soon I will return it and get the ATT.

How compatible is the atrix with T-Mobile?

Sorry if this has been answered but I'm on the xda app and can't search. I'm thinking about getting this phone and unlocking it to work on T-Mobiles network. How cross compatible is it? Will it work with the T-Mobile "4G"?

Nope, you will only get 2G (EDGE).

t-mobile and at&t use different 3G frequencies, so if you unlock it you will only get EDGE speeds. Not worthy IMO, you have lots of options in your country, i would recommend to wait for the samsung galaxy s II phone.

Will work on the network but data will be at Edge speeds, not 4G.

On the new Nexus S - if you run out of internal storage - what size memory card can you add? Oh, wait they left off the SD card slot on that model. But those super AMOLED screens are really easy on the battery right? Oh wait, if the screen is black they use less juice but not otherwise.

nowhere do they say you can use an att phone on t mobile 3G. it's been known for years that their frequencies are different and incompatible. you just didn't do your homework before purchasing.

That code process is to unlock the phone to enable it to be used with networks other than AT&T. But that doesn't get you data speed any faster than 2G/Edge using an Atrix on T-Mobile's network.

I'm a little confused here. You guys are saying that the Atrix will only get 2G/EDGE speeds on TMobile because the frequencies are different.
I am currently using the Nexus One.. how is it that I'm getting 3G speeds with a phone that is compatible with both AT&T and TMobile then??
Doesnt this mean that the Atrix should be able to get 3G speeds as long as it has the appropriate software? or am I not understanding something..

There are 2 kinds of nexus ones.. one with AWS bands (tmobile) and one with the regular 850/1900 (ATT). That's why you see them work on both tmobile and att. But a single device won't work on both bands.
It is a hardware issue. No software flashing will be able to fix it. If you bought the wrong one then you're stuck with it.

False. There's not a chance in the world that is true. T-Mo USA and AT&T use mutually exclusive bands. No carrier-branded phones carry both bands. The only modern phone that carries bands necessary for 3/4G on either network would be the upcoming, not-for-sale/developer-only Nokia N950.

The Nokia N8 and E7 also have the 3G frequencies necessary for both At&t and T-mobile, as well as Europe/Asia (850/900/1700/1900/2100). However, I agree with you that no At&t/T-mobile branded device carries all the needed bands.

Ah, I see. I didnt realize that there are 2 types of the Nexus One.
I had assumed that since they are not branded by any carriers that they were all the same device.
Thanks
I was really hoping to have my TZones internet plan, which runs at 3G speeds on the Nexus, run on an unlocked Atrix but that doesn't look possible.
Are there any phones newer than the Nexus One that will work with Tmobile 3G and are unbranded by Tmobile?
The branded Tmo android phones lock out my Tzones.

Here's a list of phones that will work with tmobile 3G. Take your pick. You may have to source it from somewhere else if you wish to buy it unlocked and unbranded.
The Nexus S is unlocked and unbranded even if you get it from tmobile. But since you are coming from the Nexus One, it is up to you if its worth the upgrade. Other than the Nexus S, have a look at dual core phones.

I have a thought as if you could change the phone frequency settings with sqlite editor i mean if you can disable the entitlement_check to enable theathering with AT&T's 2gb plan then we should be able to figure out how to change the frequency ratings of the phone to be able to run on t-mobiles 4g ... I wish that someone with a little more Knowledge could help out with this..

using AT&T phone with T-mobile SIM card

Would it be a problem using the AT&T branded SGH-I337 sim-unlocked phone with the T-Mobile SIM card here in the States?
I was told at T-Mobile store today that the voice calls and SMSs should be no problem, but mobile internet would be a big issue.
I don't know whether it's worth or even possible to reflash the phone with T-Moblie firmware.
The reason being I have 1 bar or signal at home (or even less when it rains), regular phone with international SIM card does not even pick up ATT - T-M only...
They gave me free ATT 3G MicroCell - got the full bar but in the weak areas other party still hears mostly distortion.

no,it be a problem, i bought my GF a T-Mobile unlocked S4 model M919 and she uses it on LTE here in canada all the time. Rogers and ATT have very similar networks so NO, it would def not be a problem

Everything will work. However data will only be 2G while you are on t-mobile

Would it be slower?

I'm currently using my I337 on t-mobile. Have no issues with anything, getting LTE data also

You need a few things to unlock all the bands for full coverage on T-Mobile.

What are the things you need to do? Thanks. Trying to do this now.

It will work regardless. But if you want to make it pick up all of tmobiles bands you need to unlock aws.. I did it yesterday. Worked fine without it but works way better with it... Didn't take long and was easy. Just follow the steps
FYI you Dont need tmobiles firmware. You just need your phones frequency's unlocked so its more compatible to T-Mobile. Att uses 1900 frequency and T-Mobile uses 1700, 1900 and 2200 I believe. Atts phone dont have the other frequencies unlocked without you doing it

[Q] Not getting 4G speed on iWireless (Tmobile affiliate) using ATT SGS4

Yesterday I tried to switch to iWireless (a Tmobile Affiliate in Iowa) and to my surprise I was getting Edge connection from them on my unlocked ATT Galaxy S4!
I was aware about ATT iPhone working on edge speed if we use under tmobile but samsung too?
I tried the free method available on this forum to unlock the phone. Should I request a full unlock from ATT or this is (edge speed on iWireless-Tmobile) what I should be expecting even though I get full unlock from ATT (if the method I used is not unlocking the phone fully).

Unfortunately, for 4G, iWireless uses the AWS Spectrum (1700/2100) which the Galaxy S4 doesn't support. Even the T-Mobile version doesn't due to the switch to the 1900 frequency.
Next time if you want 4G on your phone, look at the Tech Specs and make sure under UMTS it says 1700/2100. If you want 4G, your phone HAS to support that frequency.

So I guess what jd1639 suggested in above lunk will not work based on what you are saying? Because if the hardware doesn't support then unabaling it wont work.
Any comments please.

If I'm not mistaken the MF3 update unlocks that freq. I'm pretty sure I saw in some release notes on either the MF3 or the one before that unlocked that.

I have no idea, I don't have a GS4. I have a Galaxy Nexus.

Already.... This is resolved!!!
I tried unlocking all bands based on the link above and it was smooth. Bought new prepaid sim card from iWireless. And woila a nice 4G sign on status bar and the speed justified the sign
Thanks too all who took time reply. I really appreciate it!!
