Hey I was wondering if u unlock sim card on the at&t xperia play if it will connect to tmobiles 4g or at least the 3g, I will be gettin the r800at soon and wanna know if anyone has it on tmobile and if they are getting 3g or 4g.
If someone already posted this I'm sorry I searched but couldn't find anything
Thanks
You'll be getting EDGE or 2G whatever you want to call it. T-Mobile runs on a special frequency that AT&T doesn't.
That sucks that's the reson I wanted the r800at ohwell thanks for the info
Hope 3g or 4g will work once the merger happends with at&t and tmobile lol

T-mobile in the US uses the same band it uses in the UK. Thats why it differs from the other US GSM networks If you buy a EU device you can use T-Mobile 3G.

I dont mean to rain on anyones parade, but i thought id go and check this out because that didnt sound correct.
Tmobile 3g seems to require the AWS band, no available model of the xperia play carries that band.
Tmobiles setup uses one band for uplink and one for down, not one or the other, these bands being 1700 and 2100, the r800i carries 900/2100 and the r800a and r800at carry 800/850/1900/2100.
as you can see theres no 1700 band available on any xperia play model afaik. so it appears you might be sol sorry :/
Thanks for all the info so its stupid tmobile that sucks they should have just came out with a tmobile one when the one for at&t came out such jerks well at least I can play games lol ill just have to conect to wifi when I wanna download stuff or watch videos ohwell
T-Mobile needs to step up and get OFF 1700! NOBODY uses that freq! I WANT 3G
Hell ya I agree I only got tmobile cuz they had the sidekick 2 back in the day and just never changed kept doin the 2 year contract thing ohwell

When I flashed my R800at to 2 different generic stock firmwares (which changed my model number to R800i & R800a)my mobile connection changed to Edge. It also changed when I went into the settings>network mode& change it to "GSM only". It only went back to H or HSPA & 3g when I changed the APN's & changed network mode back to WCDMA (preferred)/GSM. Does that mean that the AT&T XPlay can connect to an Edge(2g) network but not Tmobile's 3g network?? What if we changed the APN? If anyone tries this please post the results here.
Ok so I was wrong & I can confirm that the Att Xperia Play will not work on Tmobile's 3g or 4g under any circumstances. Only edge/2g data will work due to the difference in bands as was mentioned here.

well... that sucks. looks like i'll be getting an amaze 4g when i get back from Africa in spring!
(i only ordered the no-contract AT&T xperia play 4g to use on the "orange" network here, i don't want to have AT&T in the states. only t-mobile and verizon have 4g in my area, and i want to keep GSM for next time i travel, so t-mobile it is)

I guess my cellphone uses EDGE, but I am not sure what it is capable of. My download speeds are so slow, that I would like to change this somehow. Reading the specs on the side of the box, says:
GSM/GPRS/EDGE 850/900/1800/1900& UMTS/HSPA Bands 1/2/5/6
Is it capable of anything other than EDGE? From what I am reading and experiencing, it seems that the speeds are not going to be anything other than slow...
What model?
What network?
Where are you?

Unless you are on 4g or wifi I'm sorry to say... it probably will be slow
Download "speedtest.net" app and check your download speed. If it's around 1.5-3mbps then that's pretty normal for 3G
Have you selected WCDMA/GSM in the Network settings, if it is only GSM you will only get EDGE speeds, if not you will get HSDPA (H Icon), I have data enabled and it works flawlessly, It had hit 6Mbps as well for me.
you will only get edge on t-mobile, ur phone doesn't have the required bands for 3g, if you were on atnt you would get 3g using the r800a.
Man, that sucks... time to change my provider...
just to clarify, im 99% sure you should, globally atnt and other 850mhz 3g band carrier phones are usually compatible, tesltra here in australia being one, and telus in canada. atnt also has their own "4g" play version with its souped up hsdpa+ radio. but technically, as far as i can tell, there is no reason your phone should not run fine on their network.
you cant get t-mobile 3g on any version of the play, tmobile actually uses 2 different bands for 3g data, and usually only phones built for t-mobile will work on its network because the 2 bands are not common anywhere else.
I have CM7 loaded, but doesn't really matter what rom I load, I can't seem to get 3G data speeds. I am getting internet, so that tells me the APN is setup correctly, just not 3G. Any thoughts?
Jason
probably need to look into a different radio
Any ideas? I tried 3 different ones!

The model I have is A7272 and I have an AT&T sim. Do you think the sim tells the phone what band to use for 3G? They have the option of a T-mobile sim, does anyone think that will work?
look up the A7272 on gsm arena to see what 3G band it supports and cross reference it with ATT's 3G band
Sent from my Desire Z via XDA App
I think it was because I had an ATT sim. I got a T-mobile sim and now I'm getting "H" everywhere. Still doesn't seem as fast as Verizon's 3G, but for $45/month I can't beat it. So the A7272 supports HSDPA 900 / 2100, is that why with the T-Mobile sim I can get H, because they have a 2100 HSDPA Frequency?
AT&T uses the 850/1900 spectrum for 3g and the 700mhz spectrum for 4g.
Since your phone supports none of those, that's why.
T-Mobile uses 1700/2100 (requiring both) or 1900 for 3g/4g. now, you only have half of the 2 spectrum requirement so you probably only have "half" 3g. Tmobile uses one spectrum for upload and one for download. I don't know which one is which, but if you only have one, that means you'll only get 3g/4g speed on either uploads or downloads, but not both.
I guess I fell into this trap as well... I bought a desire z thinking I could use 3g on it with my ATT/Straight talk sim. After unlocking and re-roming, I now see the same issue, stuck on Egde, and really slow edge at that.
jch2os, did you see a difference in your service area/call quality switching to the tmobile sim? I've been really happy using an Inspire on Straight talk with ATT's network, do you feel the tmobile service is a downgrade from what you previously had with ATT/Straight talk?
Thanks for the info!
After some research via eBay and Amazon, it turns out that there is two versions of the Desire Z. There is the A7272 which supports the WCDMA 900/2100 MHz bands and the A7275 which supports the 3G 850/1900 MHz bands.
idenlover, if your device is getting EDGE on the Straight Talk sim that runs on AT&T's bands, your device is the A7272 and you should get the T-Mobile Straight Talk sim. I myself am a G2 user on T-Mobile and I can say service and calling is pretty much crystal clear except in school, where there are numerous concrete buildings. Then again, I'm based in Miami, FL so I wouldn't know how service would be on your end. I hope this helps!
if you want AT&T you need the A7275 from bell canada.
Hi all! Look like i have the same problem. I have Desire Z from Russia - with russian symbols in a hard-keyboard. And in FIDO network i have only EGDE signal - never 3G. My question: what a part of phone i need change? Antenna? GSM-module? or something other? Please don't advice me change the phone - i need this keyboard, with russian symbols!!! )
P.S. If anybody know solution this problem in software (any radio, ROM, or etc.) - please, answer me too. I don't want a lot open the phone and change any parts, only if this really needed. )
P.P.S. If it important - my h-boot is 0.84.2000.

From what I get from your problem is that your phone doesnt support the FIDO network 3g bands. I think that is hardware locked. Hopefully somebody can chime in

add another one to the list. how did you fix your problem, if at all? this stupid edge crap is garbage.
Is this phone ever coming to United States Tmobile?
You can use any GSM xperia play model to connect to TMobile using the correct sim card and APN's.
Your phone will need to be unlocked to change the APN's.
The GSM models are R800i R800a and r800AT.
If your tmobile plan includes 4G then id suggest the AT as its AT&T 4g model.
yea but tmobiles hpsa 4g will not work right? you just get edge speeds i though?
That depends, I believe you can achieve 4g speeds if you buy the AT&T Branded R800AT xperia play. Since it is a 4g phone. But you'll have to wait for someone with better knowledge, I use straight talk.
Don't get the r800at model expecting 4g, its not going to work. ATT and Tmo have different frequencies for 4g. I'm on Tmo too and I'm stuck with edge speeds
I would get the r800i model, at least you can unlock the bootloader on that for free
Like above, you can't get 3G for T-Mo with any of them, which would require 1700/2100 band.
T-Mo is doing a deal with ATT to use their 1900 3G band for roaming, but I don't think it means you'll get 3G by default with T-Mo.
You should get the i version which lets you easily unlock the bootloader to install custom rom.
is the phone going to officially come to tmobile?
I will be finishing my contract with VZ in about 2 months and I have seriously been considering getting a R800at (AT&T Xperia PLAY) and unlocking the bootloader to also remove the simlock. So that I can use it on T-Mobile here where I live. VZ has sucky service in my area and I hate them anyways.
My question is are there anyone people here using the AT&T 4G (I know its not 4G but 3.5G Xperia PLAY) on T-Mobile and with TMo converting their 2G to AT&T 3G compatibility are you able to use the 3G service on your PLAYs?
I know the service coverage is all subjective to where you live, just curious if anyone is doing this and what their feedback / thoughts are on it.
Thank you in advance

I have the R800a on T-mobile USA and im stuck on Edge which is 2g. If you want 4G or 3.5G for your play your stuck with At&t otherwise if you go to t-mobile usa your stuck with 2g on your R800at the same boat as me.
I get 4g fine with an att sim on straight talk but sadly only 2g with t mobile sim. Suppose it doesn't matter to me though since in using r800i firmware. Stuck on 3g

An awesome rate stuck on 2G doesn't sound worth it to me.

There's a list of current locations where T-Mobile support the 1900MHz band, you'll have to check it to make sure you're in one of those area, and to be on the safe side, not on the edge but within the city zone. http://www.androidcentral.com/tags/t-mobile
I live in Miami which is one of the supported location so I did exactly that. I cancelled my LG Nexus 4 preorder since it's taking a long time to ship and bought an R800i, talk about vast gap in performance. I will report on it once it get here, but I'm already certain it'll work in my area since already tested it on other devices.
Not sure if it's possible to unlock the R800at through Sony website method though.
I'm using the $30 100min and 5gb T-Mobile plan, usually keep an extra $10 deposited which give an extra 100min, and using the Vonage app to make free outgoing VoIP call.

My brother works for HP, but knows the Utah state Region Director. (Southern ID, and UT) With the deal I would be able to get a plan with 5 lines, 3 with 500 minutes and up to 5gb of data on each, then 200 minutes on the last two phones with only 200mb of data. As it would only be my wife and I, we would be able to set it up for about $45 for both phones with the 500 each, and 5gb of data for about $50-55 a month. Currently we are paying $120 a month for VZ and its service blows.
Yes, currently where I live there is no converted 2G from T-Mobile but eventually it will roll out. I am pretty sure I can live with 2G until its converted, couldnt be any slower then VZ where I live (50-70kbps)
Did some digging, this is T-Mobile USA's spectrum chart for 2G
850 MHz/1900 MHz GSM/GPRS/EDGE/UMTS/HSPA 2G/3G
1900 MHz UMTS/HSPA/HSPA+ 3G/4G
AT&T Spectrum
Frequencies used on the AT&T Network
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
850 MHz UMTS/HSPA 3G
1900 MHz UMTS/HSPA 3G
I realize that T-Mobile service is again, subjective, but I really do love this phone and despite borrowing a S3 for about a week, and a couple other phones, I really just dont have a strong desire to jump to another phone. I really enjoy this phone for what it was designed, gaming. And each time i use a a phone to play touchscreen gaming I want to scream.
On a side note, the Region Director did mention that he estimate sometime between second to 3rd quarter of next year where I live we should go live on the 2G conversion.
Actually 2G atleast on T-Mobile is more like average of 20-30kbps, at least from my experience. You will be able to use email and xda app, and slow webbrowsing, and Google Maps. Downloading apps from the Play Store is out of the question unless its small or you want to wait long.
Edit Note: Actually the speed is faster at 80-100kbps after speedtest.
I was considering rebuying the unlocked version of the S3 as well because of this 1900mhz support, but then there is a thread in its forum with tons of people S3 having hardware death.

As I am always around wifi, at home and or at work (I work about 60 hours a week) I dont generally download from the PLAY store via 3G. And its not VZ's terribly slow data that driving me nuts its their service, I have had so many dropped calls, my wife too (Droid X)
But I guess what I am asking is, when the conversion is completed in my area, would I then be able to have 3G on this device? I guess we wont know for sure until it happens, but again T-Mobile did start converting it to give unlocked iphones on their service 3G.... and to free up spectrum for the planned rollout of their own LTE network.
I will let you know when I get my R800i in a few days, but I'm pretty certain of it. Many people have been utilizing this such as ATT iPhone owners and T-Mobile 3G worked on my Samsung Captivate.
Edit Note: Found out the R800i do not work with ATT nor T-Mobile 3G, but an unlocked R800at does.

You mention R800i. While I am looking at the R800at. Should I be looking into the R800i rather then the R800at for T-Mobile in the USA?
Also any feedback you can provide when you get your R800i would be appreciated.
Here is whats listed as the bands for the R800i:
Band
GSM 850/900/1800/1900 (Quadband)
So guessing that with those bands in mind I should be looking into the R800i if I want to utilize T-Mobile USA's 3G network, and perhaps even maybe their 3.5...?
Actually the bands you listed are GSM bands, GSM are 2G.
The 3G bands for ATT and on the R800at are: 850/1900/2100MHz. Either having 850 and/or 1900 + 2100 support will get you 3G.
For T-Mobile, 3G bands are: 1700/2100 (known as AWS or UMTS). Some area have support for 1900 like we discussed. This is where the interlap come in and where unlocked phones that support 1900/2100 bands can get 3G on both T-Mobile and ATT.
There are different levels of 3G, the coverage area might be different. Lowest level usually is UMTS, have the widest coverage and use less battery, but slowest speed, I usually get an average of 3Mbps. Then there is HSPA and HSPA+, which have a large range of speed depending on the version (check Wikipedia). T-Mobile have Dual Cell HSPA which have theoretical capability of 42Mbps, but realistically you will get half of that, and not all devices support it, I get up to 26Mbps with this, outdoor and close to the cell tower of course. From experience, I find T-Mobile obviously have faster 3G speed, but sometimes poorer building penetration.
The Play support: HSDPA 7.2Mbps and HSUPA 5.76Mbps, so that's the max speed this device will be getting on 3G.
You can check the device specs on gsmarena.com for bands support, but they are not always accurate so beware.
This is also why I recommend Nexus phones, because the last two Nexus are pentaband 3G devices, which mean they can get 3G on every GSM carrier in the world. There are few pentaband devices and fewer good pentaband phones.
Well I got my R800i, but disappointingly it doesn't get 3G with T-Mobile, but I checked the spec again and it seem the R800i only support the HSDPA 900 / 2100 bands, I didn't realize this sooner since all other international phones I have bought do support the 1900 band so I just assumed.
But the AT&T version do support the 1900 / 2100 bands, so I'm still confident if you buy that version and figure out how to unlock it, you will be able to get 3G on T-Mobile in the 1900MHz supported areas.
I did a speedtest of the 2G speed and I get around 80-100kbps download speed. So about 10kilobytes per second.
Side note, on the dialer, you can dial: *#*#4636#*#* which will bring you to a menu where you can set which band the phone will use, although it is labeled by region (you'll have to press the Menu button to bring up the option).

So after that I went on ebay looking for an unlocked R800at. Found one, not great price, but it was at a pawn shop 1.5miles from my house so I picked it up.
Here are the results: (see attached images).
Somethings I found:
-You have to search for the network operators and select specifically the 3G T-Mobile network. Might need to manually enter the APN for data/mms to work.
-With stock AT&T rom, I only seem to see the phone switching between E (2G) and H+. Since HSPA+ coverage isn't as abundant and you might see the signal deteriorate quickly depending on your location coverage. Edit: I see the 3G and H logo with R800i rom, may be it was just cosmetic?
-With stock AT&T rom, I can't seem to log into Google's Market at all regardless with Data or WiFi while using the T-Mobile sim. Maybe a limitation ATT specifically put in? But this is no problem after flashing another rom.
-As expected, Bootloader Status: Not_Rootable. So I can not get into fastboot mode meaning it require the test point method to unlock the bootloader. Still, I can easily flash the R800i ftf which will allow the NXT rom to be bootable (the ftf that work for me is the R800i_4.0.2.A.0.58_Enhanced). Then root it using "SuperOneClick", had to use x-Parts's CWM installer version 5 to correctly install cwm.
Still will have to fiddle with it more to see what else I can find. As for the R800i I will have to suck up the 15% restocking fee.

How did you unlock it for use with t-mobile? I searched the forums to no avail. The only way I can find is to use a code you have to buy or you have to request through at&t and I don't have at&t so they won't provide me with one.
I can find ways to unlock the bootloader... is that the same thing?

With the code your thinking of the sim unlock. Which you can get from AT&T, if you want the bootloader unlocked you need to get in touch with Alejandrissimo to unlock it... its a free service he offers.
Check you PM
From what I know, T-mobile's 1900MHz UMTS Band II is around in my area, but I'm stuck on EDGE. Scanning for networks when I was running the stock firmware that came with the LT26i showed T-mobile 3G along with 2G (and AT&T 2G/3G), but clicking 3G never worked for me. Now I'm running FreeXperia CM10 and it only shows T-mobile and AT&T without a 2G/3G distinction in any of them. Is anyone actually able to get on T-mobile 3G on a non-stock ROM? If yes, then how?
Bump as I would also like to know. I'm torn between getting this phone or the LT28H.
I am wanting to know this too... I am on Straight talk in Dallas TX and really want this phone, but not if I cant use it on T-Mobile's 3G.

This is EXACTLY what I am looking for.
So I just flash Hong Kong ROM (to debrand), and LT28i radio to get AWS HSPA + LTE?????
If so, how?
I have obtained required ROMs.
LT28a is SIM unlocked.
I need it to work on T-Mobile USA
