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.

So the T-Mo Touch Pro2 doesn't work on AT&T 3G?

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.

Is there a 1700MHz/2100MHz Rhodium Available that is NOT T-Mobile branded?

I have T-Mobile service and I want a non-TMO branded HSDPA capable Rhodium (TP2). T-Mobile thinks it is reasonable to charge $25 per month for data, whereas they have a $10 a month plan but they don't let you use that plan with the TP2. Having a non-branded HSDPA 1700/2100 capable Rhodium will allow me to get the $10.00 data plan on the Rhodium with T-Mobile service because they would not know the phone's IMEI.
Does a phone like this exist? Possibly in another country? If so, where can I get one?

no. tmobile is the only carrier that uses the 1700 band. if they force you into a plan when buying the phone from them, you can buy it branded but from someone else.

In the US it's the only carrier that uses 1700MHz but are there companies in other countries who sell Rhodium that use that frequency?
Would HTC ever develop a phone that uses 1700MHz that is not specifically designed for T-Mobile (ie: a generic, non carrier specific phone)?

I'm running the T-Mobile Shadow Unlimited Web plan for only 10$ a month.
What are they responding to you asking for your plan?
T-Mobile has no reason to charge you what you don't want.

Changing the ROM of your phone will NOT change the IMEI.
You'll have to use a non T-Mobile Rhodium in order to get the $10 data, but then of course you won't get 3G.
Edit: Misread the post and thought the OP was looking for a ROM to solve the problem. Oops.

I don't know what you're talking.
I'm getting 3G with the 10$ plan.
The shadow supports 3G, and I'm running it right now as we speak through internet modem.

You have a Shadow. I'm talking about the Rhodium. The Shadow is obviously not one of the phones that T-Mobile restricts from the cheaper data plan. If you had a TMO Rhodium and put your $10/month data plan SIM card into it, it would tell you, "This device is not compatible with your data plan." That's why it's in the Rhodium forums. It's not related to the Shadow.
They restrict certain phones from accessing their internet2 APN (the $10/month plan). Walk into a TMO store and try to get a new Rhodium or an Android phone... they'll tell you that you need a $25/month data plan. Even though all the data is accesible through any of their APN's, they restrict certain phones from accessing data using the cheaper data plan.

Update: The HTC Rhodium 100 (RHOD100) world version of the Rhodium supports all frequencies EXCEPT 1700. Bummer.

they dont support the 1900 too and all of the cdma frequencies. so if you want to use att, tmobile, verizon, sprint, telus, or many others, you have to use a carrier branded phone.

Thinking of purchasing a One X with Tegra 3... Sprint Carrier question

Will I be able to get it to work on Sprint's network here state side? I live in California and can get a great deal while I am here in Taiwan
I just know sprint doesn't have sim cards but there must be a way right? Also if not on sprint if I had to last resort go to another carrier?
Thanks in advance.

Sprint
No you can't use a gsm phone on cdma system. Sprint uses a different system then att or tmobile, which are gsm. The only hope for you if on sprint is if sprint themselves release this phone and if I have read correctly it might not be the quad variant. So save your money till you get home.

alternate carrier might be at&t. you can buy a micro-sim on amazon and even go for a relatively cheap prepaid phone plan. or buy the micro-sim from net10 and go for their $50/month everything "unlimited" plan - which we all know for most carriers still means limited data, you just have to find out at which point they kick you off. from what i've read, there's a similar possibility on straight-talk. i think net10 and straight-talk use the at&t towers on gsm. (on cdma, net10 where i live uses the sprint system.) i went for the at&t plan - $2/day unlimited talk/text when used (i don't talk or text that often) and a data plan (they come in different sizes/prices).

As stated, Sprint uses CDMA. Most of the world uses GSM. The international One X will never work on Sprint.

[Q] Which model is best?

I read the wiki entry http://en.wikipedia.org/wiki/Samsung_Galaxy_Note_II and there are the usual different models for each carrier and region of hte world. I have AT&T so my choices are obviously going to be either the model for AT&T or some international version that uses AT&Ts bands. Is there anything broken about the AT&T model? Any reason to consider some other model? I know some models don't have wirelsee charging and other lack the FM radio. So, which one is best?

I like the international versions . They seem to get all the attention on xda. They have many ROMs out there for the lte 7105 and it seem to get updates fast . Just my opinion

true opinion. but a few of the international ROMs have been ported to work with the ATT variant. I chose the ATT model because of warranty/LTE compatibility. i'm not sure which, if any, international variants have ATT LTE bands enabled. if some new feature/functionality is available on the international version, it will get ported to the ATT version at some point. just my 2 cents opinion.

Thank you both for your feedback.
What is LTE? Is it a band that enables faster upload/download? If I get an international one that does not have LTE will my speed suffer? Warranty isn't an issue as I'll be buying and paying full price and not getting it from AT&T (They think I still use a flip phone with unlimited data plan).

LTE provides much faster internet uploads/downloads. since i'm accustomed to seeing downloads speeds averaging 31 Mbps (uploads 20 Mbps), anything else would be much slower. three caveats: to get LTE speeds, you have to (1) be in a LTE supported market (2) use a phone with LTE radio bands compatible with ATT and (3) have your device provisioned - by ATT - for LTE speeds/access. you can keep your unlimited plan.
regarding warranty, consider who provides service should something happen with your phone. with ATT, if you have an issue within the first year (notwithstanding abuse) they'll swap with another (likely refurbished) device. that's my additional 2cents answer to your questions!
EDIT: Added a recent picture showing LTE upload speeds.

OK< thanks. That decides it then. I will get hte AT&T model. One quesiton though about #3 above. What do you mean that AT&T has to provision my device? They think I have a non-smart phone and I don't want thtem to know about my new phone since I am paying $15 a month for unlimited data (A plan they don't offer to smart phone users). On my existing phone I can get around 250kb per second speed so do you think my account is already 'provisioned' for high speed access?
Oh, I found out both the AT&T model and the international one lach the FM radio so that's one less concern I would have had about choosing the AT&T model.

i had trouble connecting to the internet and obtaining LTE speeds until they provisioned me for LTE (e.g., did something on their end). the other thing i forgot to mention is that you'll need a micro-sim card. if you had no need for LTE speeds, then i doubt you've been provisioned for it. and, if my math is correct, 30 Mbps (or 30,720 kbps) is more than 100 times faster than 250 kbps. i'll put it this way, when i tether my phone to my laptop (e.g., use my Note 2 to access the internet), it's faster than my Verizon FiOS wireless connection.

International use

Hi i want to buy a sprint lg g5 from ebay but im not sure if it will work in greece.
Does any of you know if i can use the sprint variant in greece with greek sim?
Thank you.

According to this:
https://en.wikipedia.org/wiki/List_of_LTE_networks_in_Europe
...the Greek TelCo's use three bands for LTE: 3, 7, and 20.
As reported here:
http://forum.xda-developers.com/sprint-lg-g5/help/domestic-international-lte-bands-g5-t3343645
Sprint variants of LG G5 have LTE bands 3 / 4 / 12 / 25 / 26 / 41
Three observations:
1. Unlock your LG G5 before going abroad by calling Sprint and telling them to unlock your phone
2. GSM should work as intended for voice, SMS, and slow 2G speeds of data
3. You need to be on a carrier that uses band 3. Otherwise, you'll be stuck with very slow data speeds

I unlocked mine through Sprint for international use, however do note I am a current user of Sprint. I also attempted to unlock it for domestic US use and was declined since I have wait 50 days after my current 2 year contract is complete.
You may be better off purchasing the International version or phones like the Nexus or MotoX.
