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.

[Q] Are There Different S3 versions for ATT and TMobile?

I found out quite late that Tmobile is limited to 2G data on IPhones.. (or atleast IPhone 4S). I use TMobile prepaid 3$/day package as my usage is limited and sporadic.
Considering the S3, can anyone please tell me if Samsung has released distinct versions of the S3 for the two networks, or the same model covers both?.
Thanks.

I believe att has the lte version. Yes different phones.

I suppose, the question I really wanted to ask was, is one network's version more of an international phone than the other with regards to data?... i.e if I were to take the phone to a)UK/Europe, b) Pakistan,
Would both phone be able to get atleast 3G, or, would the TMobile version still be restricted to EDGE?.
Thanks.

There are different versions of the S3 for both the ATT and TMobile. On the S2, the difference was in the apearance, where the ATT was a little more square like, and TMobile had rounded edges. In the S3 though, the only difference is the name printed on the back (where it has either the Tmobile or the ATT logo). As for the mobile network support, I think that only the radio is different. Even now, you are not limited to 2g by your phone, but rather whatever TMobile decided to give you. Both phones will get atleast 3g. I know that TMobile version does not have LTE support, but im not sure about the ATT version.

If you bring an AT&T phone to T-Mobile, you will not get 4G.
You can best 3G if your AT&T Phone has the 1900 range, you can get 3G on T-Mobile's service. Not sure how well it will be since it's only picking 1900 without others.

If you unlock your T-Mobile S3 you should be able to get 3G/HSPA+ on AT&T. The T-Mobile S3 is a pentaband device.

If you are using an iPhone you might as well do the $2 a day since the $3 will only affect you if your phone gets 4G. They will be exactly the same performance on the $2 since it will just be on unlimited EDGE.

The AT&T version does not get 3G on T-Mobile save for a few sporadic locations across the states. And yes, it also has LTE.

[Q] Which version to buy for T-mobile T-zones Users?

Hi - I have the T-mobile U.S. T-zones grandfathered plan, which phone version can I buy to get 3G speeds on that data plan?
I know Note 2 has several models. Someone told me I could use the AT&T US model if I live in a area that has been refarmed (I live in Orlando, FL).
Someone then told me I should get the Canadian model but I am having a hard time finding a site that sells the Canadian model from Wind/Videotron/Mobilicity.
Thanks

Start paying for your internet like the rest of us
Nah, just kidding. But the last time I checked on the whole "smartphones with T-zones" thing was a few years ago-.at that point, it worked with any phone that didn't need a special apn(like danger or rim devices). If that still holds true, it won't matter which model of note 2 you get. Good luck.

actually I think the frequency 1700 available for T-mobile is only available on the Canadian Wind/Videotron/Mobilicity.
The U.S. AT&T device based on what I read here works if you are in T-mobile area that is reframed.

...or international version (N7100).

I purchased the 7100 and I have T-Zones. If your in a good refarmed area you will get H/H+ I'm pulling about 5-8 Mbps here in California

Hi - how I can tell if my area is refarmed, my zip is 32828. Also, will it then stay that way, I mean will T-mobile ever change the refarmed area?
Basically am inquiring if I get the 7100 model will it be useless for me with T-zones in like a few months,etc.

[Q] T-Mobile Galaxy S4 best S4 in the US?

After considering a number of things I've been led on deciding I'd probably want to get an S4 over the other currently available smartphones. I've held off because I had wanted a more premium feeling phone other than plastic, but I realize now I can easily buy an aluminum backing+bumper replacement to give it that look and feel.
Anyways now to the question part of it... I was preferring an unlocked device, but the Internationally sold i9505 and i9500 do not have faster than 3G in the US, or so I've read.
I'm not looking to get a specific phone service right away, for now I want a solid device I'll be happy with for some years to come. Mainly as a portable device with storage and apps, and a little down the road to use it as my mobile phone.
I need some confirmation, but from what I understand the T-Mobile version would probably be the best? Due to once unlocked you can use it on both T-Mobile, or AT&T with 4G/LTE speeds. Also I am led to believe the AT&T S4 does not have the right frequencies for T-Mobile 4G/LTE.
Aside the above wireless speed question, I'd like to know:
1. What would be the point in flashing the i9505/i9500 ROM on the T-Mobile version? To remove T-Mobile association more from the phone... boot screen/software?
2. Does T-Mobile actually sell their version of the S4 at full price, not linked to any plan? Will they provide an unlock code same day, assuming I don't use the free method posted publically. I'm dreading the possibility of having to jump through hoops.
Below I have summerized what I understand about a few non-carrier specific phones....
i9505: International LTE "not working in USA", quad core CPU.
i9500: International 8 core CPU, better GPU.
S4 Google Edition: 4G/LTE capabile, Quad Core CPU, No touchwiz, comes in white color only.
Anyways looking for S4 owner's knowledge, experience and opinions here!

if youre going to pay full price you might want to consider the LTE-A version aka snapdragon 800 version
http://www.ebay.com/itm/Samsung-Gal...1271471972?pt=Cell_Phones&hash=item3384ceb764
32gb+snapdragon 800

According to that auction, it says it wont have 4G/LTE in the US? "I'm a frequency noob" One of my concerns was having something I could use on either TMobile or AT&T so I have options... if I was just looking at a 3g phone and cpu power I could just do this, or the i9500 "8 cores".

it gets hspa+ on tmobile and att it might be able to use LTE-A when tmobile and att add it to their networks
and the 8core isnt really 8 core its 4+4 = 4 low power 4 high power cores, only 1 pair of cores work at a time so its only quad core

Several threads say the 9505 can work on TMobile if you flash a compatible kernel but the 9500 is not compatible. With regard to AT&T vs. TMO compatibility, search for AWS mod. A T-Mobile salesman told me he got his girlfriend's AT&T phone to work on TMO network using that patch.

@OP
My experience is that yes, I could buy the S4 from TMO without plan, just pre-paid with a small credit. I do not live in the US,and had no problem with documentation or payment. Of course it is full price.
What the sales person told me is they will give you an unlock code only after 3 months if you are using it, reloading credit I guess. This doesn't work at all for me, but unlocking is actually real easy with the Samsun embedded app. I bought the phone and tried, it worked immediately (if it doesn't you can hand it back and have it refunded, for the restocking fee of 50USD).
Recently I used the ROM code here from Jamal (http://forum.xda-developers.com/showthread.php?t=2348272), to turn the M919 TMO into a i9505 Nexus. For me it is a massive improvement as I just cannot stand bloatware. It also free up much memory, and battery lasts longer.

The 9505 and 9500 will not get you LTE nor H+ on T-Mobile.
They will ONLY *possibly* get you 4G on AT&T.
The AT&T S4 is locked, yes. Your best bet is the T-Mobile S4.
You can flash 9505 ROMs on the T-Mobile version as well as some other ones.

Additionally, the development for the T-Mobile s4 is outstanding.

I hear the Verizon S4 has a SIM card. Aren't SIM cards for GSM phones?

Hi,
I m also freq noob and as much as I have searched the forum I cannot find the answer...I have SGH-M919 TMO and I am using it in Serbia but have network problems: receiving missed call TXT msg from operator, dropping out of network and difficulty in reconnecting to home network (need restarting).
Since TMO version supports all bands what can be the problem that phone is acting like that?
It works fine when i m on the network...we dont have LTE here nor will we for some time...
Please some help/direction to the thread dealing with this kind of problem...
Thanks

I had a stock unlocked att s4 on T-Mobile getting LTE without any mods.

[Q] Best way to get a phone that will work with Verizon and all LTE bands overseas

I've really enjoyed my S7 and want to upgrade to the S9. Later in the year I'll be overseas for almost a year, so I want something that will work with all Verizon bands of LTE, but also not have a firmware lock that would cause it to not work on other bands of LTE overseas. (planning to just use prepaid dataplan sim cards overseas)
I think my two options are to either get a US 'unlocked' version or wait for the 'international' version. My understanding is the primary differences between the unlocked and international version is the 2G/3G coverage for CDMA and possibly slightly different hardware. I'd rather have a phone with CDMA backwards capability, but my prime concern lacking full access to all LTE bands available wherever I am.
I'm not really interested in going any route that would require me to root the phone if there is a way to do it without.

Well the only way to get VZW compatibility is the VZW phone or a US unlocked model. So you're looking at the US Unlocked model at this point.

A listing of all the different model numbers available (per country and carrier) is available here: https://www.techwalls.com/samsung-galaxy-s9-sm-g960-g965-model-number-differences/
You will probably want to get the phone that works with your primary location the most. I am not sure which countries use which frequencies for LTE in Europe; you will need to research that to see what you may be missing out on.
With my T-Mobile S7, I haven't had any issues when traveling in Europe or Asia. It connects to LTE usually.

So I just did a deep dive of that list:
It looks like the Verizon and Unlocked versions are almost identical (the unlocked US version has B46(5200) 4G TDD LTE, but I'm not sure anyone who uses it)
Looking at 4G FDD LTE it looks like a Verizon or US unlocked phone will have almost complete coverage around the world, notable gaps are B30(2300) in China/Canada/US AT&T, B32(1500) in UK and B71(600) (US Tmobile). I thought that was a bit confusing as you'd expect a US Unlocked phone to service all LTE bands available in the US yet it lacks AT&T and Tmobile bands.
So based on all that information looks like I should just get an unlocked US phone to be totally safe, and I'd likely also be fine getting a Verizon version also.

So I'm new to Android but i use Verizon prepaid. Will I lose anything by going with the unlocked version or should i stick with a Verizon S9?
I don't use video calling. All i do is text and talk but I've heard that people on Verizon prepaid have issues with unlocked Android phones.

Would Wifi Calling work with the US unlocked on verizon? I thought that required a Verizon FW to be flashed. I imagine all the other features such as voLTE / HD calling, etc to work on the US unlocked.

I did a cursory review of the wifi-calling FAQ on their website. They don't mention anything about compatibility with Unlocked versions of phones (that I saw). I'd call tech support to ask, but I'd expect there to be a 50% chance of getting the wrong answer from the tech based on my interactions with their support.
There might be some good experience based anecdotes in the Galaxy S8 forum, if it works on an unlocked S8 its a safe bet it will work on an unlocked S9
I think I'll ask in the Verizon subreddit, it seems like they normally have really good information as well.
I'm mostly curious about the LTE TDD Band 46 (5200) - its the only band an unlocked US phone has that a Verizon phone doesn't. 5200 is in the U-NII frequency range, no cellphone service providers use it, but I wonder if it may be used for local LTE networks in the near future. The other advantage is avoiding all the verizon bloat wear, but that may be what allows the Wifi Calling to work!

All this has me thinking I might have to add the extra $80 and just buy the Verizon version. I don't get phones on contract and I've always just paid full price. (Page 2 404 error?)

Apparently the Nov/Dec Samsung s8 firmware update added an option for BYOD carrier provisioning for unlocked s8. Given the similarity, I'd imagine the same to be true for s9. Can someone who has an unlocked s8 confirm?

Well after a little more research I see that if you use Verizon prepaid you lose visual voicemail and WiFi calling even if you use a Verizon phone so there's no need in me paying extra for a Verizon S9. Unlocked it is.

You might wanna check this as Verizon is starting to implement network locks on some devices as to deter thefts more
Dont know when or what devices but it was a statement Verizon made

So, you're saying the prepaid SIM might not work in an unlocked S9?
I don't think Verizon is keeping Verizon prepaid SIMS from working in unlocked phones they are just locking their phones like Sprint and AT&T still do.
I had no problems with my unlocked Pixel 2 XL that I purchased from Google and my Verizon prepaid, just no visual voicemail.
