Hey everyone,

I just picked up a new Z3 Unlocked with Dual sim mode and was having a very weird issue. I can make calls when the wifi is on, however, I do not receive incoming calls. It will ring twice and go to VM. Has anyone experienced this or know of way to fix it??

I've set the APN setting and everything works fine. I get LTE with AT&T and I have no issues except the issue with incoming calls on wifi.

Thanks guys.

I don't think you actually have wifi calling, as far as I know only tmo has a Z3 capable of wifi calling and its enabled by them and not Sony. I'm not sure if AT&T has even rolled out wifi calling on any phones yet, they've only stated their iPhones would get it sometime in 2015. Not sure how to solve your issue, but it can't be wifi calling.

Im not sure what it is exactly. It seems as if it wont switch between wifi and the network to receive calls. I cant turn on my wifi at home because ill miss calls.

Anyone have any other suggestions?

The more detail you can provide about what you are attempting to do, what works and what does not, and the settings/state of your phone, the better.

Dumb question first: Are you sure you are on AT&T, not T-Mobile?

Also, is your Z3 T-Mobile branded by any chance? (You might then want to flash debranded Sony firmware... see the Android Development forum).

Do you have cellular coverage in your area? If you turn WiFi off (and be sure Airplane mode is off also!), are you able to send/receive any calls at all? Can you call voicemail? (Note that calling and receiving call is not dependent on data settings, such as APN).

Do you have another SIM nearby that you can try? (e.g. your SO's...)

Are you sure you have not configured your phone for SIP (VoIP)? Go to Settings -> Call Settings -> Internet Call Settings -> Use Internet calling -- make sure that it says Only to SIP address. (Internet calling is great -- I forward calls to my VOIPo number when unavailable/unanswered, where I can also "spoof" my outgoing number to match my cell phone number, receive my voice mails as email attachments, make calls from my computer, etc... but that's probably a couple of steps ahead).

VOIPo.

I also use PhonePower for my "landline". We have a couple of SIP phones at home, and when going on vacations etc. we simply pick up our "home" calls on our cell phones (using the built-in SIP clients in Android and (gasp) Symbian).

PhonePower is better for international calls (VOIPo has a couple of restrictions, and also does not correctly interpret the "+" prefix in telephone numbers, the way I store them in my phonebook), whereas VOIPo is better as a "transparent" replacement for your cell phone number (if your cell phone is out of coverage, or in airplane mode), in that it can "spoof" the outgoing caller ID to match your cell phone number. (You'll have to verify it first of course).
