I see the new Z1 Compact phone was announced as being exclusive to T-Mobile in the US. Since T-M and AT&T are both GSM, will the T-Mobile Z1c work with AT&T (GoPhone) if it is unlocked?
Was thinking about joining GoPhone but would really like to have this and/or the S4 Mini (separate thread) as an option.

Based off the specs on the Sony Website, it will work on our network.
However a few notes - It does have the correct LTE bands to work on AT&T's LTE network (2 and 4), but we also use band 17 as well, which this device does not support.
UMTS (3G/HSPA+) access should be fine as the device supports our bands (850/1900).
You may need to program your APN settings into the device manually.

Hope this helps!

Thanks. How would not having band 17 affect coverage. For instance, is it used only in certain regions? If so, do you know where?

Good question. What's the importance of band 17, and which areas would this be more important?

my question is this, i have tried to research a sony phone for the last year or so and have not been able to get a straight answer from sony and forums out there. This is so frustrating because i get several different answers about which sony phone will work with att while getting 4g lte. I wamnt the sony z1 compact when it somes out, i already have att service and just need to know will it work with att and receive 4g service is the us area (philly). If not i will just stick with what i have for now. I know the 6903 and 6906 z1 will work, that is what im being told. I appreciate your input with this.

I would like an answer to this too. It seems like we are completely covered for EDGE/HSPA+/LTE except LTE band 17. I am in the Portland, Oregon area and would like to know if band 17 is utilized here.

Just thought I'd add what I found online:
"AT&T* announced in an 8-K filing today that it has agreed to acquire spectrum in the 700 MHz B band from Verizon Wireless for $1.9 billion in cash and Advanced Wireless Services (AWS) spectrum licenses in several markets, including Phoenix, Ariz., Los Angeles and Fresno, Calif. and Portland, Ore.
The 700 MHz licenses to be acquired by AT&T cover 42 million people in 18 states — California, Colorado, Florida, Idaho, Illinois, Louisiana, Montana, New Mexico, New York, Ohio, Oklahoma, South Dakota, Tennessee, Texas, Utah, Virginia, Washington and Wyoming."
700Mhz equates to LTE band 17, so this should help understand the impact.

Sorry for the delay since I am not on this forum all the time.... I also have a spared AT&T LG G2 unlocked LTE 4G phone when I took my Sony Z1 compact to the local AT&T store for help. I really can't and unable to answer your question in detail, I can tell you this, the AT&T store service rep spent about half an hour on her iPad searching for some info then went back to my Sony "Setting-More-Mobile network settings-Access Point Names-APNs" and did all the data entry there, at first, it didn't work, then she decided to use my LG G2's IMEI instead of the one from Sony, then the AT&T network accepted and the LTE signal came on immediately. My SMS, internet, email and multimidia are all working, as I said, this Sony is lack of LTE Band 17 (LTE 700), therefore, in some area you only gets the H+ (HSPDA) signal, in some area you do get the LTE 4G signal here in Northern Calif. I guess it all depends on which AT&T store service rep you talk to regards this APN setup. Good luck.

Tcharfa, I think that I can provide the Sony Z1 Compact APNs setting that AT&T store rep set for you:
Name - AT&T Phone
APN - Phone
Proxy - Not set
Port - Not set.
User Name - Not set.
Password - Not set.
Server - Not set.
MMSC - http://mmsc.mobile.att.net
MMS proxy - proxy.mobile.att.net
MMS port - 80
MCC - 310
MNC - 410
Authentication type - None
APN type - mms,default,supl
APN protocol - IPv4
APN roaming protocol - IPv4
Bearer - Unspecified
MVNO type - None
OK, That's it, now anyone who has the Sony Z1 Compact can just copy the above info and setup your APN to the same and you will get AT&T LTE 4G network, again it still depends on the AT&T LTE 4G coverage area specific in your area. Good luck.

i have the z1 compact. and att disabled lte on me. so do not call.
I wished i found this apn info.
when i called they removed my old phone from the system and when they tried to get the imei in to the system they couldn't put it in without removing the lte data plan.
so they got me back to the regular datapro.

you seem to know what your talking about, i have a sony z1 c6906 and it works great. I get 4g lte and all is well. I want the Z1 compact but i just would like to know yes or no if im going to get 4g lte or not. I have been reading some people say yes and some say no. I basically want to know should i get this phone??? if i cant get LTE in the us a then i will hjust forget about the phone. I appreciate your input.
the currently available Z1 compact (model D5503) will not have full LTE support on AT&T as it's missing the LTE band 17 that AT&T uses (noted by many other posts in this thread). Judging by the numbering scheme of recent Xperia phones the US model (if ever released) would be model D5506 and will be fully compatible with AT&T LTE. I can't find any references to such model being in existence though

OK GOOD NEWS to anyone who is struggling whether to get a z1c due to LTE compability.
I just received my Xperia Z1 Compact D5503, purchased from eBay, it's a unlocked international model. I plug my sim card in, and only got four bars with no Edge, HSPA, or LTE displayed. I went to APN setting, and it was blank. So I follow the previous post in this forum and input all the APN setting entry manually, as soon as I hit "Save" and the blue dot to enable this APN setting, the LTE icon poped out right away. So if anyone is worried if z1c will have LTE or not, yes it will have, at least in Southern California it will.
Now, to the friend who says he couldn't get picture message through, you need to make sure you have "mms" in the APN Type field.
Some Z1c (very rare) will automatically download the ATT apn setting to their phone, but most cases you need to input them manually.
Let me know if you have any question.
