Does the network frequency of Arc fit T-mobile? I can use 3G in China, but only GPRS available here in America with T-mobile network.
Anyone can help me?
Thanks
What is your phone code number, in America it is Lt15a, a is American, if you use i, this can be a problem maybe, they have different frequence like you said, first you can ask this to Sony Ericsson i guess?

HI all, thanks here for all your help. I finnaly have my unlock code from T-mobile UK, for 30 pounds, but i think it is workth it.
Now using the PRO as a phone, it is kinds weird to get used to. I live inthe US and i put my T-MOble US sim card in, when i check the settings, i found out for some strange reason that the GSM band it was using was EGSM+DCS1800, i don't know what this band is, but i noticed that i don;t get enought bars, always loosing signal, and i have put the new 1.08 radio rom on it. My SK65 gets better signal.
The only other option i see there for GSM band is PCS1900, so i have manually set it to this. My question is, which band should i be using? whats the diffrence? and when setting up WAP for MMS, do i use WAP1.2 or WAP2.0.
Also does the UTMS2100 mean it will work on Sprints 2100 network?
Thanks.
Search is your friend
All of the Universal forums are full of information about why the MDA Pro is not as useful in the US because it is just Tri-Band. T-Mo USA uses GSM/GPRS 1900 for voice and data. You need to stick to this band alone. Try using WAP 1.2 for WAP. There's no EDGE available on the Uni.
No, Sprint won't work It's different technology using a different standard. You can only use UMTS in Europe, the Middle and Far East. That's why this device is targeted for these markets and was never brought to North America. And it never will be.
Let's hope the successor to the Universal can do it by incorporating the latest technologies prevalent in North America.
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 all,
I have a Sony Ericsson Xperia X10i, but it does not support (activated) HSPA 850 Mhz networks. Is it possible to activate this? I know that the Xperia X10a does support 850 Mhz. Is the 850Mhz HSPA option locked by software. If so, how can it be unlocked.
It's a really great phone. I already use this phone on 2G and want to switch to 3G.
Help please.

Unfortunately, like most cases of this, it is a hardware limitation. This is why they made two completely different models (X10a and X10i). It isn't just software that controls it, but it goes right down to the cellular radio in the phone itself.
Your best bet is to either switch to a network that supports the bands of the X10i (T-Mobile USA and Wind Mobile in Canada) or sell the device. I am sure some people who do use T-Mobile might be interested in the X10i as it works on that 3G network.
Thanks a lot for your quick reply. So now i know i don't have to research the internet for a solution. In my country Suriname, there is only one 3G provider, unfortunately on 850 Mhz).
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)
good staff
Yesterday I was updating my arc via wotan, and some people told me that the firmware works on the arc s arc normally.
I even upgraded to version ultyima and was normal.
but wondered if changes anything, if it can be harmful or not?
you wont access 3G.... the LT18a uses american 3g bands (850/1900) wether LT15 runs Euro 3g bands (900/2100)..
Let me know if you can get 3G after doing this.
