[Q] O2 Xperia Play...R800i/R800a/R800at, which one?

Hi guys...just curious if anyone here have bought the phone from O2? Would love to know if the one u get is R800a or R800at rather than R800i (which is most probably not the case rite?)? I'm travelling to the US a lot and the network interoperability is the issue here. Would love to have the phone coz I could kill a lot of time during flights and stuff but 3G is a real issue here coz my trip is usually for work so e-mail/web is ultimately unavoidable -_-''

Unless I'm mistaken, the R800a and R800at (not even released anywhere), are sold only in North America - in Canada or on eBay. I think everywhere else gets the R800i. And the R800i is definitely not 3G capable in the US. It will only work on EDGE.

O2 Uk/IE/GER etc will be the R800i be it generic or with their own bloatware.
as stated R800a and R800at are US/Canada. Not sure what the model in Asian markets is.
European market is always an i with Sony Ericsson

Some people have the r800x

R800x is Verizon Wireless, 'a' is always Americas with SE and at is AT&T device.
Still not sure of model number in Asia (Japan) market

Fwiw, the "AT&T" variant they gave out at Google I/O is the R800a.
Which of course doesn't mean the AT&T consumer model will be anything similar if/when such a thing exists.

thanks guys....just in case if there's any one found an odd case (e.g. in europe but got R800a/at), pls post here...would be great to learn of those stuff...lol

Mine is an att play. Has the boot with att images and apps. Just wish I could root it but comes on 2.3.3 so no luck yet

I think japan is also the r800i the only ones with custom models are the Usa - R800a, R800at, R800x and china z1i? Everyone else seems to have got the r800i

I know this is an old forum, but.......
can anybody tell me the differences between the models? well i suppose i dont want all the differences; the main thing i want to know is:
will the digitizer for an r800i work for and r800a? i have a strong feeling it will and a little bit of evidence that shows that it should, but i thought i would ask to see if anybody else would know. thanks.

Someone can probably back me up or correct me but I think really the only difference between the models is just the region they come from(The r800x is a Verizon Wireless version and it is stock android vs the Sony skinned one the r800i or r800a has)

Help Please! Will the galaxy nexus work with Mobilicity?

Hey Everyone,
I recently pre-ordered the Galaxy Nexus from Bell on contract for three years thinking that Wind and Mobilicty are CDMA. (I know, I'm crazy). I have just figured out that they are in fact a GSM network. My question is that if I changed my order from bell from a three year contract to unlocked, will it work on Mobilicity's service? I know there probably won't be 4G speeds but if I can get a plan with unlimited calling and data for $17.50 per month instead of the 500mb and 200 minutes im getting with Bell for $50 a month, I'd rather get it unlocked.
Note: If you say it will work, please provide some evidence of some sort, e.g. some specs that state that the Galaxy Nexus will work with Mobilicity's network
Thanks so much everyone, and if you could reply as fast as possible it would be extremely appreciated as the promotion that they have for $17.50 might be over really soon so I'll buy it right away.
-Mosh

Galaxy Nexus is penta-band 3G phone...so the HSPA version will work on that network.
You're ok with it,enjoy the phone.

Are you sure? I don't mind having slow speeds (HSPA) but my budget is really low and I really want to make sure that the phone will work with Mobilicity out of the box

Yes it will work. Relax

Thanks, but could anyone point me to specifications for the galaxy nexus which tells me what frequencies or radios they use? I'm really bad at this kind of stuff
Thanks again all

Even though you would have a hard time finding any GSM/UMTS/HSPA network it doesn't work on you could always check the list on Wikipedia.
http://en.wikipedia.org/wiki/List_of_UMTS_networks#Americas
It says Mobilicity uses the same frequencies as T-Mobile US, a frequency that is both listed in the official specs and is something some people is already using it on without issues.

Edit: So the Galaxy Nexus works with 1700 band IV (AWS)? http://imgur.com/NJrCK
Edit2: So, according to http://www.gsmarena.com/samsung_galaxy_nexus-4219.php, the galaxy nexus has the following:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1700 / 1900 / 2100
So Mobilicity definitely supports this?
Edit 3: According to a Wikipedia page on Mobilicity:
"Network
The company also has a cell-site sharing agreement with Bell Mobility to share cell tower space in all Mobilicity zones[12]. The network uses the UMTS IV frequency band, also known as AWS, to provide UMTS (with HSPA) service[13]. Using this band, user equipment transmits at 1710–1755 MHz, and receives at 2110–2155 MHz. AWS is the same frequency as Wind Mobile and Videotron in Canada and T-Mobile USA. Like WIND, Mobilicity does not have a 2G, EDGE, GPRS GSM Network.
Mobilicity's network is compatible with the same handsets and devices as Wind Mobile and Videotron networks, and UMTS handsets and devices offered by T-Mobile USA.

I already said so, yes. Should be no problem. My mention of T-Mobile US was only if you wanted to know actual users who are already running it on those frequencies.
Yes, it's a UMTS handset that works with T-Mobile USA. I don't know how I can make it any clearer.
EDIT: Well, to clarify it a bit more I can say that HSPA (HSDPA and HSUPA) HSPA+ are improvements upon UMTS. In other words, every HSPA device is a UMTS device.

Perfect, thanks so much!Also, according to other websites it has UTMS 1700/2100 or HSDPA 850 / 900 / 1700 / 1900 / 2100 or Network (3G) HSDPA 850 / 900 / 1700 / 1900 / 2100 so basically it will work for sure right?
Sorry for repeatedly asking the same thing, I just want to be sure. One more yes, and I'm going to change the order from 3 year term to unlocked

How many different ways do we have to say this? It has quadband GSM and pentaband 3G, if you put in a North American SIM in the phone, it will work.

[Q] Can the HTC One X be used with T-Mobile?

Hi, I was just wondering if the HTC One X (Unlocked) be used with T-Mobile, because I'm currently using a Samsung Galaxy S2 (Hercules) and the lack of ICS is pi**ing me off, I miss my HTC Sensation in which I had ICS months ago; I don't think T-mobile is planning on releasing ICS for the SGS2 somewhere near the future.
For now I'm stuck between Samsung Galaxy Nexus, Galaxy Note and The HTC One X but I don't know if either of the will work on T-Mobile . Can someone please let me know. Sorry for my english.

Puerto Rico I travel a lot to the states as I work for U.S Deparment of Defense.

This is a very good question. Tmobile claims to use 1700/2100 band for 3g/4g
The specs for the ONE X are : WCDMA/HSPA 850/900/1900//2100 MHz
And GPRS/EDGE/GSM 850/900/1800/1900 MHz
From this information I am unsure whether it will be fully compatible. These numbers look more like an ATT phone than tmobile. Im assuming it will work with edge but 4g is most likely not going to happen. I ordered a one x and intend on using it with t-mobile, so it would definately be beneficial if someone was confident it would work on tmobiles network. Hopefully someone will have one and test it on tmobiles network before I get mine in the mail.

420kushking is correct regarding the spectrums.
However, there are reports that T-Mo iPhone users were able to use 3G on T-Mo network. I've also checked T-Mo spectrums, PCS 1900 mhz 3G spectrums are available on T-Mo on areas in the US. If you're planning to use T-Mo and plan to get the phone, you should probably call T-Mo to see if 1900 mhz is available in the areas you'll be going to most often and make sure that you'll be able to get 3G coverage on your phone. If you ask if the phone will work on T-Mo, the customer service will probably say something like the phone will work on T-Mo but they can't guarantee if the 3G will work on the phone. So it's better to ask of the spectrum is available instead, that might be a safer bet. Even tho the spectrum may be available, but that probably doesn't mean that the 3G will definitely work. These are just some information for you to consider.
I'm also planning to get a One X to use on T-Mo, and hopefully what they say about the 1900 mhz spectrums are true. I couldn't test the 1900 mhz spectrum on my Desire HD because of the 900/2100 bands on the phone.

Well yeah it will work but will it be able to utilize the 4g network I think is the question here. I have already pre-ordered the one X unlocked version and I do have tmobile. I will be doing extensive data speed tests when I get the One X, but I do not expect anything better than an EDGE connection on T-mobiles network.
To me this is a big deal because if the One X does not work with 4g on tmobile, It also wont work with 4g on ATT because its the Tegra 3 version, and if you have been looking at specs the tegra 3 unlocked version does NOT support LTE... If I dont get the speeds I need then it will end up on eBay.

The one x will get 4G speeds on att. "4G" as in HSPA+ not LTE. So you'll get decent speeds, just not LTE speeds. I Wouldn't bet that the one x will work on tmobiles 3G networks let alone their 4G networks. Edge seems about right.

Thanks to you all for answering my question, I was about to pre-order it on when I read that it was "Sim-free", what does that mean, does that mean it has no sim card slot. Im kinda confused here.

Never mind after a bit or reading I've learned that sim-free means it comes with ail, but it does has sim card slot.

SIM-Free means you can use whatever network uses GSM

I don't think the One X will support Tmobile AWS band. The only hope for this phone to work on Tmobile 3G/4G is if Tmobile has switched 3G/4G over to the 1900 band in your area.
Sent from my HTC Incredible S using xda premium

Realistically? No, since it doesn't support the AWS Band (1700 AND 2100).
However, if you live in an area when TMo has deployed the 1900 band, it will work. If you live in that area, that is.
Also, "sim-free" means it comes straight from the manufacturer, without a carrier's SIM card.

Nope 1700mhz/2100mhz in here... Sad but true

I was looking for the specs at gsmarena and I found that the at&t versions supports the following bands:
2G Network
GSM 850 / 900 / 1800 / 1900
3G Network
HSDPA 850 / 1700 / 1900 / 2100
4G Network
LTE 700 MHz Class 17 / 1700 / 2100
I'm not too familiar with this subject but I believe that T-Mobile uses 1700/2100mhz, does this means the At&t is a true candidate for T-Mobile Compatibility?

I think the version of the phone you would be referring to is the one X att version, It has a dual core qualcomm s4 krait instead of the tegra 3 processor. There is some debate over the performance of the krait vs the tegra 3. I know from a benchmark video that the tegra 3 outperformed the transformer prime. I think the krait outperformed the tegra 3 though by a bit. I ordered the unlocked one x that has the tegra 3 so it doesnt support tmobile 4g or att 4g based off the specs. When I get it I will test on both networks. My concern is that since I ordered the tegra 3 version, it wont be supported by ATT 4g OR t-mobile 4g. We will see I guess.

Ok good to know. Does anyone have information about speed tests on their regular 4g network? Is the LTE that much faster to where it would be worth it to invest in an LTE based less storage model? I have both att and T-mobile but I think the 4g on t-mobile is faster based off my speed tests. I do NOT have an LTE device to test the differences. I am in Los Angeles/ Orange county area.

I'm considering switching to T-Mobile with an unlocked One X, and appreciate the info in this thread. One question: some are saying it will work with HSPA+ on ATT. Will the phone roam to ATT if it sees an EDGE network in range, or will I be stuck with the lower speed? Oh, and does TMob charge for data roaming to ATT HSPA+?

specs conflicts

i've researched this phone for sometime now and i've noticed many contradictions and confusions with specs from different websites online
1- lt28h is the NON LTE model, official white paper says that it has the hspa+ bands 850/900/1700/1900/2100 with download speeds of 42Mbps
( 4g capable which isnt brought up anywhere) also the 1700mhz band is omitted from all major review and seller websites that i've seen, i
emailed gsmarena and they just fixed it (1700/2100 as of now will run T mobile USA 3g/4g until re frame is done )
2- lt28i has hspa+ bands 850/1700/1900/2100 and LTE 700/1700 from white paper, which also all websites that i came across omit the hspa+
1700mhz band which with 2100 can run t mobile hspa with download speeds up to 21.1Mbps and future LTE development
3- many reviews and sellers are confusing the 3 versions lt28i (international with LTE) lt28at ( at&t locked, hspa+ Bands 850/1900/2100, LTE
700/1700) and lt28h ( international hspa+ 850/900/1700/1900/2100, non LTE)
4- sony store lists the battery for lt28at as 1500mAh Vs ("1900mAh typical and 1840mAh minimum") for lt28i and lt28h
hopefully this clears things up a bit, all specs are available at sony white papers
any insight or corrections are welcome

Sent my contact at Sony an email to see if he can't clear up the issues regarding battery size on the LT28at and whether or not the LT28i supports 1700/2100 (and if it does, does the LT28at also support those bands even though its carrier locked)

Okay just got an email back. The website listing the ion with a 1500mAh battery is a typo. Should be 1930mAh. He will check on the network bands (1700/2100) and is gonna see if there is a white paper for the LT28at specifically.
His thinking and mine was that AT&T just didn't want people to see that the LT28at had T-Mobile supported network bands.
Will let you know what more I hear.

White paper doesn't list the 1700 band but my friend is gonna check still.

Received a new version today of the white paper: https://docs.google.com/open?id=0ByrrmqPijqISM2dBcFpwNUpaTG8

thank you for all the info
so there is quite a bit of wrong information spread across major cell phone websites, engadget, cnet, gsmarena, phone arena...
so lt28i can run t-mobile hspa+ at 21/5.8 Mbps and is future proof for lte
lt28at is at&t locked and what is sold through sony store in usa
lt28h is the non lte model and would run on t mobile hspa+ at 42/5.8 Mbps
maybe the failed at&t/t-mobile merger explains how the lt28i was available for a while and then a revised at&t version had to be done

Just wondering. If all versions actually have 1700/2100 bands, would it be more beneficial to purchase the lt28i over the lt28h and be able to run it on an AWS network like t-mobile?

Yes because the LT28i can be purchased unlocked but the LT28at can't be and there are no ways to unlock it currently.

I had the same problem when I was shopping for the LT28i. I was really hoping it was 850/900/1900/2100. GSM arena seemed to be the source of this misinformation and it spread to eBay. I emailed many sellers and they refused to look at the box to check since it is printed on there. I checked Sony Taiwan's website (the only place the LT28i was sold at the time) and it said 850/900/1900/2100 so I took a gamble. I was wrong. It is, as you say, 850/1700/1900/2100, making it the weirdest band frequency ever. A bit of a disappointment for me since I live in Sweden and my provider had 900 coverage, but whatever. Their 2100 is perfectly fine.
If you want more confirmation, I attached a screenshot of the configuration info screen from my LT28i.

I meant I was missing UMTS 900, not GSM. My carrier is a 3G-only network with UMTS 900/2100.

so this model has 1700/2100? i've been looking for xperia's with this band.

What? Weird. The LT28i is available here. No UMTS BC8 (900)? Oh my. Might as well check the Sony shop here if they will release the LT28h variant. I don't know if my carrier is using the 900 band for HSPA. Fingers crossed that it is 2100.
I might encounter a problem with that 900 band when in roaming, too.

Relative to the other major UMTS bands, 900 is scarcely used. Nearly all operators of UMTS 900 networks primarily operate a UMTS 2100 network and they're using 900 for rural coverage or to augment urban coverage for the purposes of building penetration and capacity.
My home network (3 Sweden) has a 900 network but as far as I can tell I'm not missing out on anything by having the LT28i. My last couple phones had 900 and I'm not noticing any difference.

[Q] R800at for USA T-Mobile - Anyone using this setup?

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.
I would look into: Sprint, Boost Mobile, Metro PCS.
(Not sure if Virgin Mobile and Straight Talk are CDMA tho)

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
