Hi guys,
I'm currently an AT&T customer who's thinking to switch to Tmobile's
$30/month for Unlimited text&web plan
After googled some articles regarding AT&T X10a and the Tmobile(USA) 3G
I'm still not really clear about some key facts.
Please allow me to explain my situation now:
Origin: I bought it from AT&T store
Unlocked? YES
Model: X10a (I found this on the sticker located on the back of my phone)
********************************************************
But I flashed to different baseband and ROM
Info. I found in the "About Phone"
Model number: X10i
Android version: 2.3.3
Baseband version: 2.1.71
Kerel version:2.6.29-00054-g5f01537
[email protected]#1
ROM: Wolf_Xperia_6.0.0s (Android 2.3)
I found a thread and somebody mentioned about:
"The AT&T XPERIA X10A supports the 850HMz, 900MHz, 1800MHz, 1900MHz, and 2100HMz bands. So since the phone doesn't support the needed 1700MHz band, the phone will be stuck with 2G speed on the T-Mobile network if you continue using the Sony Ericsson generic world 2.1 (for X10A) firmware."
Currently, I am using AT&T SIM card and data plan as well, and I have NO problem getting "H" at most of the time and sometimes "3G"
Q1: Is that means my phone is STILL X10a but not X10i which was shown
in the "About Phone"?
Q2: I will NOT get Tmobile HSPA/3G working on my phone, unless I get a X10i?
or I can flash it and/or de-brand it?
This question might be asked somewhere, but my case is a bit different,
since I am using different baseband and ROM from stock.
If anyone had same experience and/or you already knew the answer,
please help me out
Thanks in advance
James
X10a will remain x10a even though it shows x10i. For the 3g I am pretty sure T-Mobile is 1900Mhz for gsm? Correct me if I am wrong

Thanks, that helps a lot.
btw I knew that T-mobile uses 1700/2100 for its HSPA

Yes, like jailbroken iphones, an X10a will only receive at about 119kbps (edge) when connected to T-Mobile network.

I have North American version of RAY ST18a (WCDMA / HSPA 850 Mhz, 1900 Mhz) All mods and custom kernels are done for ST18i version. If i will use them i will loose my 3G network capabilities.
How i can flash / port 3G WCDMA radio park of the kernel from ST18a to ST18i ROM?
Hi, you don't have to worry. The bands are hardware. The mods and custom kernels will not affect your 3G capabilities. I have an ST18a as well.
Only thing is.. It will show up as an ST18i on the google market... but that's purely aesthetic
So then is there any SW difference I ans A ? There should be one...
I've installed doom kernel, no problem. But when I try to put CM 7.0x mod in CWM it returns an error that my phone is ST18i and can't proceed...
Hi, My name is Masaki, I'm from Peru, I have a problem with my Xperia X10a, my phone was operator locked (I buy it from my friend, he uses this phone with movistar operator but I have a line with another operator called claro.
My friend say he can unlock the operator lock, for this, he use a program called medusa box, after a few minutes he finally can unlock the phone, but, now, the phone only can connect to edge band, the 3G don't work anymore, somebody can help me?
Masaki
PS:
All work ok in the phone, I tried original rom (android 2.1), updated rom (2.3.3) custom rom... custom kernel, with no result...
when I choose "only WCDMA mode", I lost the singal (phone and data) and a error appear (no operator found), only work when I use "GSM only" or "prefered WCDMA to GSM" (but work in GSM/edge mode only)
the local operator (both) are X10a band compatible
Did you try relocking the phone ?
Maybe a bad unlock procedure.

weird problem
can't lock again with that soft.
You can try this. I found that in some roms it is more easy to change than in others. Miui roms seem to have more settings to change than stock based roms.

Since Claro doesn't use 2100 MHz band you will have Edge only. Or switch to carrier with 2100 band for 3G.

Well, if 850 and 1900 are what is supported in your Country, and both 850 and 1900 are not available in the X10i, it probably would be best for you to sell the X10i and buy an X10a.

Since your OP stated it was an X10i, that would have been the problem with no hspa. I am not sure but perhaps restoring to original 2.3.3 and baseband following the link below exactly might get your hspa working. Good luck.

x10a
My phone is a x10a model from the start, I tried the original rom from local claro (android 1.6 and android 2.1) I tried the SE generic version update (android 2.3.3) custom roms + Kernel: doom kernel 1133 + Xperia S ported to X10 from chickensito (Android 2.3.7)
The problem still remain
I tried to set the apn manually... no result

Tried x10i bands maybe your unlock changed your phone into a x10i what is your baseband I am just speculating

people have helped you and you need to find a new carrier as the one you have dose not support the radio frequencies of the x10a try to trade sell it and buy a x10i or get a carrier that supports the radio of the phone you have.
x10a
My local carrier (both) work with Xperia X10a, X10i don't work here.
try if you can get a band on another carrier preferably does have the the
2100mhz band just to confirm that your radio is working

Found a solution yet?? I have a similar problem with my X10a.
I'm with Telcel in México, simlocked (i got my cellphone from Telcel), but the radio signal is not working, tried with another sim card and got the same result...
carrier
there is only 2 carrier in my country, and don't work with 2100 freq
No, my problem is not solved. any ideas?
tried reflashing x10a baseband? any errors when forcing 3g mode? e.g can't enable radio etc.... ?

Hello all!
I bought a THL W8 in Argentina, and I noticied that it works ok in GSM (QUAD BAND) but in WCDMA it only works in 850/2100.
I just ask if there is any baseband flasheable zip to enable 850/1900 instead of 850/2100 knowing that maybe its included in the hardware but capped by software baseband.
Thanks!!!
Hi, I need help.
So, I bought 2 moto E 2015 model (at&t unlocked) from Ebay - very cheap.
But this phones working with only 2G mode in my country (even theese are LTE models ).
I want to reinstall system to better one - which there is no any at&t default applications or any of carrier applications.
And I also want to change baseband versions - because, this phone working only with 2G network type with my country's mobile carriers. I think it should be for baseband (network standarts) .
is it possible to fix problem with change firmware and baseband to no-contract version?
I asked my mobile carrier, they said, "we are using 900-1800 MHZ for GSM ; 900-2100 for 3G, 2100 for LTE (up to 2100)
Who can provide how to and links?
Thanks.
The AT&T model cannot be bootloader unlocked, so you cannot change the firmware to another version. There's a guide in the General forum about enabling additional LTE bands, you can try tweaking it for 3G, but there's no guarantee that the AT&T model's antenna hardware can support those bands.
