Hey jsut wondering if anybody on this site is in the Ontario area and where they got their phone + when..
I cant seem to find an xperia play that works on local frequencies.
I recently received the one i ordered off Amazon. But it is not accepting my SIM, it cant even be unlocked cuz its an international phone..
Is there anything I can DO?
These are the frecuencies supported by Xperia Play in its GSM version:
GSM GPRS/EDGE 850, 900, 1800, 1900
UMTS HSPA 900, 2100 (Global except Americas)
UMTS HSPA 800, 850, 1900, 2100 (Americas)
Probably the UMTS frecuencies for America are supported by the R800a and the other ones by the R800i.
If you need a R800a and you have a R800i maybe you can flash a R800a rom to modify the supported frecuencies. Search this issue in the forum, you could find something about it.
Try flashing the R800a firmware and see if the phone will accept the card. Otherwise you are out of luck. Should have bought an R800a from rogers and simply unlock it.
I dont think this will work as an R800a can flash an R800i firmware and the frequencies still run on the R800a frequencies.
Edit: I bought my phone off someone from Kijiji for $200 a year and a half ago. It was locked to Rogers. I bought an unlock code for it and unlocked it. Then put in my Bell SIM card and input the Bell APN for data/MMS. Then I got my bootloader unlocked. So I am using a Rogers R800a, with a Bell SIM running MIUI v2.9.21 r1 from cosmic DAN.

i bought this ARC from hongkong and now im in canada
but i never found the 3G network, and then i go to Fido store
i changed a SIM card.But nothing change.
and finally i found the problem: My Lt15i is only support UMTS/HSPA 900/2100
And i wanna to know if i can fix by change CDA or the driver of baseband?
no way to change the band compatibility... it's hardware related. your best bet is to sell that one and buy the arc from rogers
I had the same issue. I did receive the LT15i so it only works on EDGE.
eBAY is going to refund the money when I return the phone
I will then buy a LT15a which will work on our bands.
I'm amazed you don't know this. You buy a Hong Kong phone or a European phone, it is not 3G Canada. Hey, this is XDA. This is where they're supposed to know.
Here's a pro tip regarding Sony Ericsson phones.
last letter a = North American GSM frequencies (850/1900/2100)
last letter i = Global GSM frequencies (900/1800/2100)
last letter c = Chinese GSM frequencies and may be TD-SCDMA
LT15a is Xperia Arc for AT&T/Rogers/Fido/Bell/Telus frequencies.
LT15i is Xperia Arc for Europe, Asia, Africa and Australia GSM frequencies.
SO-01C is Xperia Arc for Japan.
Is there an LT15c?
What about Brazil?

Brazil uses the "a" version.
I'm just wondering to the OP what did you do?
I realize I have the same problem.
I too bought an arc in hong kong. Actually it was meant for my mother, but I traded her with my x10.
My arc LT15i network only works on edge.
I think it's funny how my x10 works great in hong kong while the arc can't connect to 3g here.
Is there a service provider that would be in that same frequency?
I'm currently with fido.
[Edit] Excuse me for reviving dead post.
Switch to LT15a_3.0.1.A.0.145_NAM
maybe works
Here in Brazil, works with LT15a
But works LT15i
But if 3G is hardware problem, I'm sorry!
Greetings
Do not buy a internation version phone unless u clearly know the phone 3g band. It is because most of the international version wont work in most of the carrier in north america. I believe it is because frequency 850 only used in north america, so they have to make a "special" edition for north america carrier.
Also you can't change the baseband to get the 3g network, since it is hardware problem, not software.
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
Sent from my R800at using XDA Premium App
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)

I live in the UK and have an O2 Xperia Play. Its an r800i and now its unlocked.
Hello everyone!!
I have a R800i with these networks: UMTS HSPA 900 (Band VIII), 2100 (Band I) GSM GPRS/EDGE 850, 900, 1800, 1900
Unfortunately I have just seen that the country that I am now, supports only 850 (Band V) and 1900 (Band II). I see that these are supported on R800a, but unfortunately I do not have that model, only R800i. Is there a way I can get it to work on these bands? Maybe flashing the radio or something like that? Can you please let me know your thoughts on this?
Thanks for your help!
Are you in the states? I have the same question since I have att service. I just want to know if 3G will work with a R800i. I've read on these forums not to get the R800i if you want 3g but Amazon only carries the R800i. SIGH~~~~
You have to flash R800a firmware.

Could you tell me which firmware works? I have the same question.
Moved to Q & A
The firmwares are in a thread I made in the development section. Link in my signature. Go grab one and try it out.
Also, make sure you have the right APN settings.
You could also try using the 36 baseband, which is hanging around somewhere in the forums.

Does it matter which firmware runs on which phone?
For example, running LT15i firmware on LT15a, or LT15a firmware on LT15i?
We know the radio ability is different on both phones, would that cause an issue?
Does using a wrong FW disable some radio abilities?

Yes it does matter. I think you can still use it because they have the same GSM bands.
BUT you cannot use 3G or HSPA if you use the wrong firmware. LT15i and LT15a have different 3G bands. Better check what your network provider is utilizing.
Or check the cellphone shops whether they sell the i type or the a type.
LT15i = UMTS HSPA 900 (Band VIII), 2100 (Band I)
LT15a = UMTS HSPA 800 (Band VI), 850 (Band V), 1900 (Band II),
2100 (Band I)
The UMTS bands are provided in the white paper of arc at SE developer world site.
i have a rogers branded LT15A and i flashed it with the generic firmware for the LT15i and 3g works fine. so far so good. when i used to have the x10 it ran fine with either version of software. i am not saying that there couldnt be an issue, just not one that i have had that i can directly attribute to using the international software instead of the north american one

I think firmware interchangeability is a one way deal for the LT15i and the LT15a, in the sense that you can flash an LT15i ROM on your LT15a device and still use 3G (I'm on rogers, and 3G works), but flashing a LT15a ROM onto a LT15i will not give you the 3G bands of the LT15a
I also flashed my Rogers LT15a with the LT15i 2.3.3 World Generic firmware
All running fine

Are you sure about this?
I just too, like the above two posters, flashed a world generic LT15i to LT15a and working fine on Rogers.
According to Wiki, rogers UMTS is operating on 850 and 1900 bands, both not supported by LT15i.
Is there something hidden in the drivers etc?

This is somewhat confusing. I used Xperia X8 before going to Xperia arc.
They mentioned that flashing the i or a version incorrectly will make 3G connection not possible (http://forum.xda-developers.com/showthread.php?t=875688)
I didn't even try to flash the a version before because my network provider is using the 2100 MHz band for UMTS (2100 frequency is present in the two versions)
I've checked Rogers wireless and noted that the network is indeed using 850/1900 bands for UMTS. Kinda weird that LT15i firmware is working.
It shouldn't matter what firmware you flash onto your phone.
Since v2.1, all firmwares have included the software portion of both "i" and "a" radios meaning you can run any firmware on any phone. (However, this DOESN'T mean that flashing an "i" firmware onto an "a" phone will give it "i"-frequency 3G when in an "i" coverage zone and vice versa. The hardware is what determines what 3G frequencies the phone is capable of handling and that is fixed.)
It's how people are already flashing the latest 2.3.3 update on North American arcs.
Make sure that you enter in your APN settings correctly once flashed. I've never had issue running any ROM and getting 3G data connectivity.

you beat me to it. you are correct
Do you think that this would work for a Neo (MT15i) phone too?
(would be a bless as f/w patches are more quickly available for the arc)
Just bought Xperia arc LT15A but when I check phone version it says LT15I. So i called the seller and im told that it was flashed with LT15I firmware thats why its showing as LT15I. Is that possible that it will show as LT15i? Box shows lt15a by the way and im a little confuse. Also what are the settings for APN I will be using it with Rogers network (data/mms). Thanks in advance.

Yep, flashing a LT15i firmware on a LT15a will change the name under "about". This is normal and should not affect the functionality of your phone. Rogers APN below:

Thanks pre I cant wait to add tweaks and apps to this phone.
What means (CDMA) and (GSM) In Title of Rom? And I live in Brazil and my 3g is not working.Thanks
GSM is when it needs a SIM card for it to work, CDMA the SIM card is built in and is part of the device, and locked to a specific CDMA based network.
Have you tried changing the APN settings to match that of your carrier's?
Thanks, researched it, my carrier operates in the 850 MHz frequency, and the xperia play r800i not have this frequency.
I believe it can operate at the 850 mhz band, you just need to flash the correct baseband for it. I have no idea which one you need to flash on your phone though...
