[Q] Z1 Compact on ATT 4G LTE Network

Hello,

I just got my new Z1c from eBay. After popping in my ATT micro Sim card the APN was automatically filled in for me. I did double check with the one online and it was exact for LTE use. I was then immediately prompted for kitkat 4.4.4 update which after research, it was safe to do so.

Anyway, i am located in Raleigh, NC and here are the results (Seems to be using Band 4 [1700 MHz AWS]).

(Image attached)


For the most part great LTE coverage in Raleigh, but when i go out to the country i get HSPA+ (where as my ATT HTC One mini gets LTE [Band 17]). However HSPA+ speeds is acceptable and with the Z1c specs i am not complaining at all.



Just a note on signal icons:
ATT Stock Phones = Sony Xperia Z1c

2g = Edge (E)
3g = HSPA (H)
4g = HSPA+ (H+)
4g LTE = 4g OR LTE (This icon will vary depending what firmware region your z1c came from. but both mean the same thing, so if you get a 4G icon on your Xperia on an ATT network, then you are getting their LTE signal)


EDIT:: I will be traveling to Washington DC next weekend. It is claimed that ATT uses Band 2 up there. I'll keep you up to date if i get LTE signal as well as Speed test screenshots.

I'm in DC area, there's no LTE for me. I just switched to tmobile a few hours ago, but data isn't working. #fml

Hi all,

I just to let you all know that Z1c LTE capabilities are good, here in Uruguay(South America, search for it in google maps), the LTE network from provider ANTEL is working very fast, check out the speed in the attached image.

it's nothing wrong with this phone.. it's all carrier related.

Best regards.

Like no Data at all?! Not good. I will be needing data while up there!

EDIT: Did you switch the APN from T-Mobile to AT&T?

I switched from ATT service to tmo, it was just some provisioning issue, tmo LTE is working fine now

I was in DC and Dulles/Reston area, and i was able to get AT&T LTE. Speeds were a bit slow for LTE but it was during the day, perhaps many people on the network.

Question for you guys: I see some of you guys are using the Z1 Compact on AT&T. How does it show up on the Online Account Manager? As an unidentified phone?

I'm currently using the Sony Xperia S (not recognized by AT&T's system), but I think I need a phone with more processing power.

I'm considering purchasing this phone for use with AT&T. Could any people in the GA Sandy Springs area weigh in on the LTE coverage around here?

AT&T will not allow their LTE service on unlocked phones

I have been with AT&T since they acquired Cingular. The Xperia Z1 Compact is my first LTE capable phone. The APN settings automatically downloaded to my phone, but AT&T still needed to activate the data for some reason.

Unfortunately, like what some previous posts mentioned, AT&T does not recognize the IMEI number as being an LTE capable phone. And I was told by three customer representatives and then tech support that, since the phone is unlocked, AT&T will not allow LTE service to be delivered to the phone.

Shockingly I was told this would be the case for ANY unlocked phone! So if you plan on getting this phone or any LTE unlocked phone, in my experience with AT&T, you won't be able to use their LTE network.

Unless, according to previous posters, you give AT&T an IMEI number of a phone AT&T recognizes as LTE capable. Since this my first LTE capable phone on the network I don't have an IMEI number of an AT&T branded LTE capable phone. So I'm out of luck with getting LTE service.

Does anyone have any suggestions? I'm partial to Sony phones so am I basically never going to be able to use LTE if I stay with AT&T? Is T-mobile the same? So frustrating.

I have used a Sony ZL 6506 unlocked and just put my AT&T iPhone SIM card in it and picked up LTE just fine, FYI

I just got my Sony Z1 Compact and I get LTE Band 4 in Baton Rouge and Band 2 in Covington/Mandeville, La. I saw a list of other cities where AT&T uses Bands 2,4,5 so soon as I can find it, I will post...and keep adding cities based on feedback...

Hey all,

Just activated a Z1C on Cricket (AT&T) and was initially only getting HSPA+.

Noticed that by default in the "Mobile network settings" the preferred network type was set to "WCDMA (preferred)/GSM".

Changed this to LTE (preferred)/WCDMA/GSM and I started picking up LTE.

Hope this helps someone.
