Questions about using a Touch Pro2 from T-Mobile on AT&T

So I have a Touch Pro2 on my personal T-Mobile account. My company has issued me a iPhone for my work phone. Which they pay for 100%. My question is if I unlock my Touch Pro2 and put my sim card from my iPhone in the TP2 will AT&T change my data plan to a PDA one? Since I do not pay my company phone bill I don't want to do anything to change that plan or add more money to it without permission. By the way the iPhone is mine so if I leave the company I take it with me. So I want to get the Touch Pro2 to work on my company line so I can sell the iPhone pocket some cash and cancel my personal line.

At&T data plans
the iphone plan and the PDA plan are completely different features and are not cross compatible. If the company bought you an iphone, in order to make the internet work on the TP2 you will have to have the feature changed out, if it is the company's account, you may not have that access to make the change, and internet won't work until it is changed.

You dont need a pda plan to use a unlocked touch pro 2 from tmobile i have one and im on att, the tmobile version doesnt register on the att network so the most they can charge is the lowest data plan. as far as your plan the iphone plan is probably the only plan that doesnt change on its own, although if you put the sim in your touch pro 2 youll still get data and still be charger the iphone plan. but remember your only get edge dta speeds with a unlocked version.

That is correct. Tmobile TP2 has different 3G radio hardware than ATT. I got a Tmobile TP2 and unlocked it to use on ATT so that they couldnt take away my $19 unlimited data plan. the Edge radio works and thats fast enough for what I use the phone for.

I have tp2 on att network also but i cant connect to aim or any instant messaging programs what should i do. I configured the settings to connect to the internet and it works.but i cant use aim,yahoo,and myspace im.

Well seeing as how my previous company phone was BlackBerry Curve running edge I don't think it would be entirely a problem.

Is it faster or slower?
HTML:

How different? Is T-Mobile chip is faster than AT&T chip or slower? If I'm with T-Mobile TP2 phone and AT&T service what will happen if I'll flash the latest AT&T stock radio on the T-Mobile phone?

3G on TP2 w/AT&T
Is there any way to get the 3G to work on my TP2 (unlocked T-mobile)with my at&t 3G sim card ??? It is so f***ing slow!
Please don't tell me that I have to buy Tilt 2 to have it work!

Buy a Tilt 2.

I just got Tilt 2!

You're taken care of now, but just for the record, the TMo and ATT 3G services propagate over different frequencies. The 3G radio in the TMo phone is tuned to transmit/receive 3G info over TMo's frequencies, and the Tilt2 is tuned to transmit/receive 3G info over ATT's frequencies. It's not a question of which chip is faster, but rather which chip can access which carrier's 3G frequency.
Most GSM phones have quad-band edge, meaning they can access edge-speed data on most carriers. But most branded GSM phones have only their particular carrier's 3g band.
Flashing the ATT ROM onto the TMo phone won't affect the speed of the 3g radio, as it is a hardware difference, not a software difference.

Thanks, I figured it will be easy to buy Tilt 2

damn it !!!
So are u saying that my tmobile phone will never work on ATT with 3G?? this is CRAP! if there is no hardware difference why cant there be a workaround ? radio related maybe to unable the phone to use ATT 3g frequency???

TMOBILE HTC Touch PRO 2 has different hardware -meant to read "band" specifically for Tmobile's 3g.
ATT TILT 2 has hardware specific for ATTs 3g network.
You can use Tmobile phones on ATT using Edge..but you will never get to ATTs 3g network. You simply just dont have the hardware. It's just like buying a phone that has not internal GPS chip and no matter how you flash it or add/remove software, you simply can't use the turn-by-turn navi software (unless you use an external bluetooth device).

Additionally, anyone know about the radio compatibility of a HTC branded TP2? I purchased mine already unlocked, and not sure if I can get 3G from ATT or not...

Yup, that is exactly what I feared...Good to know, and I Think mine will end up on Craigslist before long.

the reason the 3G wont work is because the 2 carriers use different basebands for service. While they both have 3G capabilites, ATT uses 850 and 1900 and Tmobile uses 1700 and 2100... it may have changed but i know thats what it used to be. It is the same reason that (forgive me for mentioning the dang thing) the iphone 3G wont work on tmobile, it will only work at EDGE speeds.

ATT 3G Help me

OK call me foolish but I got fed up with TMobile and switched to ATT because the company offered to pay my data plan to keep me on call. I had been saying no but a billing problem that they refused to fix left me steamed. Anyway, is there anyway to make AT&T 3G work on my Tmobile TP2?

T-mobile is only edge...you cant use 3g unless you have a tilt 2

Let me rephrase that, for all the people that got "confusimacated" at first glance (like me)
The T-Mobile TP2 will work on AT&T's system, but it will only be capable of EDGE, and not 3G due to the fact that AT&T's and T-Mobile's 3G service use different frequencies.

Overseas Version
I have the overseas HD2 (LEO) which in not branded by T-Mobile. I also have ATT, can i get 3g on it?

at&t 3G is on the WCDMA 850/1900 megahertz bands. The Leo operates on EU frequencies, 900/2100 WCDMA for 3G service. Your Tmobile gets 3G on the 1700 MGHZ band. You need a phone with NA 3G frequencies to get 3G from at&t, and those are 850/1900 WCDMA. None of your devices will see 3G here in NA. Europe operates 3G on 1900 and 2100 and a few on 900 WCDMA, Japan and South Korea are on 2100 WCDMA only and NA is on 850/1900, so you need to be really careful of the hardware you purchase for it to work where you want it to and at the speeds you want. Edge comes on the older GSM frequencies and almost all phones have the 4 GSM frequencies, 850-900-1900-1800, but none have all the GSM and all the WCDMA frequencies, could but don't. Most US phones will have 3 WCDMA frequencies, 850-1900-2100. Better to buy an unlocked tilt 2 or sign an agreeement with at&t for a discounted phone.
Good luck.

[Q] switching gsm bands

is it possible or is there a hack or rom to switch gsm bands on a att tilt 2 on a different network to get 3g or hsdpa/hsupa speeds?

Are you kidding me? I answered you not once, not twice, but THREE times!
Let me make this clear:
IT IS NOT POSSIBLE TO USE 3G SERVICES ON YOUR TILT2 ON AN AWS NETWORK. GET A NEW PHONE OR DEAL WITH IT.

my bad....geez.....!

This is a hardware issue, the ATT phone doesn't have the same kind of 3g modem.

Can I use unlocked ATT S3 on tmobile $30 monthly 4g?

I am reading it might work on edge only is that true?

Different Bands... no 4g, just E... Maybe someone know more than me but IMO you cant use 4g

You can use the phone but you will be restricted to Edge data speeds. ATT and Tmo use different freq bands for 3G/HSPA.
ATT uses 850/1900
Tmo uses 1700/2100
You may be able to get 3G/HSPA speeds once Tmo refarms its 2G bands as 3G, but who know when that will be.

You will only get EDGE in MOST areas, T-Mobile is "re-farming" the 1900mhz spectrum from 2g to 3g/HSPA. They are doing this in order to be able to use the iPhone on their network, but it would have the same effect for any unlocked phone. They say they'll have their entire network re-farmed by the end of next year. I haven't found an official map, but this has places where it has been sighted: http://www.airportal.de/

Looks like there are many spots in Bay Area, CA.

I tried this on my att S3 and got the sim card and was on the phone with tmobile tech for hours...it never worked and he was trying to tell me it was my phone....not...my phone works great with straight talk.

It definitely works on the AT&T phones. I unlocked mine and bought a tmobile prepaid sim the other day. Able to get 3g in San Jose but still only Edge where I live. Will be switching and dropping at&T once the refarm hits my area.

[Q] HELP-N7105(LTE) not getting 3G at all with T-Mobile!!!

Hey guys! I brought my international GT-N7105 Note II LTE model from Asia and bought that unlimited cheap 30 dollar plan. I checked the towers and my area does have those refarmed 1900MHz towers from their twitter. Anyhow, first i just thought it was my house and I have drove from pasadena-los angeles - Irvine - Orange County and have yet to see ANY 3G/H/H+ signals! Always stuck on the E (2G). First I thought it was the SIM problem so I put that SIM to an iPHONE4 and guess what?! There is the T-Mobile 3G right on that upper left hand corner and speeds are decent. Anywhere from 1.5mbps-6mbps. I'm sure it can go higher but looking at that dinky screen is already enough for my eyes! Is there some specific settings I should be doing? Somehow it's NOT locking to the 3G towers from my N7105. I am planning to get Straight Talk's 45 dollar deal at Walmart and choose the ATT since it's got better coverage from what I hear. Thanks for the help in advance and Happy Holidays everybody!!!

I don't think the 7105 has 1900 band, I have 7100 and I get 3G coverage.

Thanks for the reply but according to this: http://www.smartone.com/jsp/phone/english/detail_v12.jsp?id=2553
It should have 1900MHz just like the N7100 except there's LTE which won't work. There's absolutely no excuse for it NOT to have 3G! This stinks and is frustrating!

I see that it has 1900 band but under GSM, when looking at 3G bands it has HSDPA 850 / 900 / 2100 - N7105 vs N7100 having HSDPA 850 / 900 / 1900 / 2100
Dont know if it makes any difference but thats why I steered away from the LTE version.
Try this go into service mode: *#197328640# Debug screen Phone Control Network Control & Band Selection. Check if you can enable or see if you have the 1900 band under WCDMA. Might have to go under Combi Bands and select the desired bands.

Just flowing up if it worked out for u or not?

Bumping this since the op didn't respond. I am having the same trouble and I attempted the fix you provided and found that my N7105 lacks the "combi bands"
I mistakenly purchased this phone for pre-paid here in America (should have gotten the n7100) and it seems that Straight Talk doesn't have AT&T cards anymore and I'm stuck on T-Mobile's EDGE service

I have the verizon model and use it with tmobile
So the last two weeks have been the most frustratying and nerve racking weeks ever as I have tried to get tmobile service to work well with the verizon model i have. And although I am definately still irritated, i have to say that I do get 3G and HSDPA on mine, just not anywhere near my house. This has driven me crazy and until today I assumed it was my phone and the lack of certain bands howev er after purchasing a Tmobile 4G hotspot and activating it on a new 300mb plan just to see how well it works, I have found that it was never my phone that sucked at my hopuse, its Tmobiles service that sucks!. BUT... to get the best consistant coverage with the Tmobile sim in my Verizon model I did have to experiment with the APNs quite a bit, and I also upgraded the modem to the newest one released . For anyone tryinbg to do thius with the verizon model, make sure your APN for T-Mobile US or T-Mobile Data (I personally have started using it as T-Mobile Data) has "None" typed in for the username and for APN if your using LTE device type in "fast.tmobile.com" instead of the epc.tmobile...... or whatever it is. Does anyone know if flashing a modem or radio or even just the rom from the tmobile section would help at all? Or would it just **** up the phone..

Despite not getting 3g (since I lack the appropriate physical antenna apparently) I get way better cover with T-Mobile (through Straight Talk) I have to say compared to Verizon. Maybe my Note 2 is much better than my old Thunderbolt or maybe T-Mobile is just a bit better. Nevertheless every building at my university is made of reinforced concrete so you'd be hard pressed to get any reception in the classrooms. I find in places I had no service I have service, and places I had some service I have great service now.
Back on topic though:
I can get the 1900mhz through GSM but that isn't the same and my phone lacks whatever that Combi Bands thing is. So I don't know if it is a lost cause or not. I just figured I'd bring this back up since the OP never responded and I am in the same boat as they are (were?). Maybe a solution can be found or just "it ain't gonna work."

Just following up I have returned my N7105 in favor of a N7100 and get great H+ and 3G through T-Mobile/Straight Talk.

Fwiw, net10 is basically the same as straight talk. When you buy the $15 simcard pack from bestbuy for net10, it comes with 3 different sim cards in it. One of them is a micro sim that fits in the note2 and runs on at&t's network.
