[Q] Sony Xperia Z T-Mobile to AT&T - Xperia Z Q&A, Help & Troubleshooting

I have a T-Mobile Sony Xperia Z and I'm about to unlock it from T-Mobile. I was wondering if it will be compatiable with AT&T and what kind of speeds would I get. I live in Houston Texas.

[Q] C6603 only gets edge in US?

I just bought a UK version xperia z model: C6603
A lot of people proved that Xperia Z DOES work on ATT's 3G network
It is so weird that my xperia z only has edge
I‘m currently using Straight Talk in USA ( I don't think it's a problem of Straight Talk, because its network is also powered by AT&T, my lumia 920 has LTE using exactly the same sim card)
I tried factory reset, LTE/WCDMA preferred/WCDMA only, flash another ROM - not work
Is there anyone having the same issue? The speed of edge really freaks me out
Anyone can help me? THANKS!!

im on h20 with the xperia z c6603 in the states. currently get an abysmal 0.15mbps d/l, & 1.12u/l.
if any one is using one of the other mvnos and receiving better numbers, please share your experience.
If you wanted full HSPA+ support you want the C6602. The C6603 will only get HSPA in areas that are running the right frequency which is spotty.

Depends on the frequencies used by your carrier for which modes. The 6603 does not cover the 1700 & 1900MHz bands for 3G used by quite a few carriers in the US

Xperia TX LT29i on Wind Mobile

Just to let everyone know that my Xperia TX LT29i is running nicely without any issue on Wind Mobile (Canada).
This phone will run on AWS (1700MHz and 2100MHz), but unfortunately Wind is not selling this model.
Device support for AWS is limited, message here if you have any questions.

[Q] AWS 1700/2100 Wind Mobile (Canada) on the Z, via ZL radio?

Hey all. it looks like Wind mobile is now selling the Xperia ZL.
http://shop.windmobile.ca/ProductCa...s.aspx?id=SONY+Xperia+ZL(WINDCA)&color=orange
Go figure. However, does this mean that we can flash their radio to our Z and get access to wind's frequencies? I haven't tried my wind sim since flashing another ZL radio earlier this week for better telus compatability, does anyone have any experience with this, or a rom dump of Wind's ZL?
It came with 4.2 pre-installed once they got it.

xperia t lt30t att 4glte

basic question? I thought the att phones were called "Xperia LT lt30at."
if a phone on ebay says "Xperia T lt30at," is that the same? will it work on att 4glte as well?
what's the difference? thanks
The first one is wrong, the second one Is correct.
LT30at is the Xperia T from at&t which works with specific LTE bands (good only for the at&t network)

Yes, I meant TL, sorry.
Have a look at my list here: http://forum.xda-developers.com/showthread.php?t=2648320
I wrote Xperia TL [LT30at], I didn't remember anymore
Xperia T [LT30p] = international xperia T without LTE bands
Xperia T LTE [LT30a] = international xperia T with LTE bands
Xperia TL [LT30at] = xperia T with LTE bands for AT&T network only
So on eBay it's better you contact the seller before buying...
