Tmobile Z3 D6616 poor signal - Xperia Z3 Q&A, Help & Troubleshooting

Hi guys,
My Z3 D6616 Tmobile signal is weak when I travel to Asia country and use the local SIM here. I use the same sim in the HTC One M7 Sprint that was unlocked to use global SIM and the signal is very good but when I put that sim in my Z3 D6616 and the signal is not stable and poor. I tried some other sims but it was the same.
Is there anyone meet this issue ?
What should I do to install or do something with it because I also love my Z3 ?
Thank you very much !

[Q] Question about Xperia Z3 models and service

I was curious to find out what is the difference is between the Z3 models?
I was about to purchase this:
http://www.ebay.com/itm/221566146447...:MEBIDX:IT
But after further research i saw that different models we having an issue using 4g LTE service.
Basically is there any issue running the D5803? I have AT&T and I didn't want to risk dropping $500 on a cellphone that would be restricted by my carrier to 2G.
Any help would be much appreciated!

I would opt for the D6603 first if you can find it and swing the $ or the dual SIM D6633. D6603 has more support for LTE bands ATT and Tmo but the D6633 will also work. I have the D6633 on US Tmobile and LTE and HSPA+ service is excellent.
Thanks for the info, but what is the real difference between the D6633 and the D5803? What would i need an additional sim slot for?
I guess a better question is what are the disadvantages of the D5803?
Thanks
Looks like I figured it out the D5803 is the 4.6" display. I did not know that. Its a good thing i probed a bit deeper. Id much rather have the 5.2"
Is there any particular model of the 5.2" i should be on the look out for?

Which Z3 model to get for ATT for LTE connectivity

Was trying to track down which model of the Z3 I should buy in order to get LTE access on ATT. I have seen some people say to get the 6603 but I was reading a thread that it wasn't working on ATT. Anyone using this phone on ATT and know exactly which model to get in order to use LTE?
The D6603 and D6633 (Dual) both support all of the needed bands for AT&T support. I use a D6633 and have no issues whatsoever on AT&T.
I also use D6633 and get LTE on ATT
D6603 and D6633 will support AT&T LTE. Whatever you do, do not give AT&T your updated IMEI or their system will register it as "unknown" device and you will get 3G only.
I'm using the D6603 on AT&T with no problems (getting LTE just fine).

Thinking of buying unlocked D6603 on AT&T

Hello,
I'm currently on AT&T with an HTC One M7. I've had my fair share of rooting and playing around with this and with my contract ending in 2 months, I've been eyeing the Z3 as my go to device for the next 2 years and intend on buying it before my contract is up to just replace my HTC soon.
1) Currently it would be a hassle for me to call AT&T to get a new nano SIM card, so I guess that purchasing a cutter to convert my current one into a nano SIM would be fine? I wouldn't need to call them up to mess around with a new IMEI or anything assuming I'm basically using the exact same SIM card?
2) I've heard that the D6633 version (dual SIM) has full support for AT&T LTE whereas D6603 is merely only 4G. Can anyone clarify this?
Thank you
I have full LTE on AT&T. I just needed to have a nano SIM card installed at an AT&T store. There were zero issues.

I've also got full LTE on a D6603 on AT&T--speed leaves HSPA+ in the dust. Purchased directly from Sony store and registered as a new line with the guy in the AT&T store scanning the box for the IMEI code. No problems at all although it does seem to need a strong LTE signal. At home I have to switch network mode to WCDMA/GSM or it will constantly hunt between LTE and H+ with a significant battery hit.

D6653

Hi All
just got hold of a second user D6653 ,I read that there might be problems with LTE so rang 3UK my provider who said it should be fine except for the low frequency LTE
BTW I live in non LTE area so cant check
Anyone know have any experience with this thanks
I'm guessing there are no other difference with the D6603
ok the LTE works ok in town on 3UK ...I'm better off with a D6603 for roms?

Xperia Z5 Compact not receiving 4G signal with Rogers Canada

Hi everyone,
I just got my Xperia Z5 Compact from my dad, but the problem is that I can not get 4G signal with Rogers Canada. My Z5 Compact was bought from the US
I asked support from Rogers and they said since Rogers does not carry the Xperia Z5 Compact, and my sim is working properly with other phones, they cannot offer me help.
My phone current settings:
- Preferred network type: LTE (preferred)/WCDMA/GSM
- Rogers LTE - Itemobile.apn
Can someone help me? Thank you!

Check if the bands and frequencies of your carrier match the bands and frequencies supported by the device. There is more to it than just it being 4G LTE. If bands and frequencies don't match, it won't work.
Also, your radio/modem may not be compatible. Some devices that move to a different network have to flash a modem to work on the other network. That doesn't mean that a compatible modem is available for your device though. Some devices switching networks have to live without 4G because the device hardware just doesn't support what the network has regardless of what software you apply.
I DO NOT PROVIDE HELP IN PM, KEEP IT IN THE THREADS FOR EVERYONE TO SHARE
A USA purchased X5 Compact has all the LTE bands that Rogers uses. As long as the APN settings are correct (and I'd assume that these settings come from the SIM card), the phone should work. Does it work otherwise, just not with 4G?
