Does this mean that I will be able to place and/or receive phone calls over Wi-Fi when I have Airplane Mode on with Wi-Fi enabled?
Yes as long as the "AT&T Wifi" banner is up and you're connected to a decent enough fully compatible WiFi source then yes both incoming and outgoing calls can be relieved over WiFi as an added bonus benefit not mentioned much you'll also be able to send/receive texts , picture or multimedia messages too
That wouldn't be airplane mode..... airplane mode disables all communications emitting from the device (bluetooth, wifi, etc.)
You do know you can enable/force WiFi on whilst in airplane mode do you not?
It was terrible for both my wife and I during the trial period. Tons of dropped calls and many times when one person couldn't hear the other. We ended up turning it off.
Was the trial time intended for tech fixing? Any chance that it actually works now? I honestly doubt we'll bother trying again. It was a frustrating week neither of us wants to repeat.
There could be a number of reasons why you both had issues non the least if it was early on in the Beta period the expectations shouldn't of been set too high.
That being said possibilities can include:
Not a fully compatible WiFi connection
Poss issues with the WiFi Connection and or ISP used
Were you in a targeted Beta market?
( Upon discussing issues with ATT in the Beta period was informed ONLY Chicago, Manhattan and 2 or 3 other markets were ever intended to be allowed in the Beta yet people found ways to trick/forcibly join )
Persons you both called may not of had compatible coverage/devices on their end
WiFi Calling has improved over the testing period and I would urge you both to give it at least 1 more chance and not completely discredit/discount it if there is potential it could at some point be useful to you
How is battery life on wifi calling. Heard mixed reviews from tmob and sprint users
Pretty good not much noticeable issue or difference
Does this affect the billing in a way?
If you get a paper bill in the mail you'll see a section labeled "WiFi Minutes used" split into night/weekend , Daytime, and Mobile 2 Mobile if applicable
If you get a detailed bill which lists/breakdowns ALL Your usage
WiFi Calling will have a feature code differing from regular calls
If you view your call/usage logs in your online account or the MyATT APP calls will also have a special feature code.
So far on the paper bill I see them listed/coded as WIFI in the online coding it labels em PVWIFI
If by billion you meant costs sorry for the long winded reply. The answer is no
WiFi Calling or WiFi Call Blocking are both 100% FREE Features however looks like all accounts will/must have 1 or the other I'd assume by default accounts whom activated like myself will have "ATT WiFi Calling Feature $0.00" on their account by default while others who've not activated or AT&T records show as ineligible based on plan, region, device etc. will by default have the "ATT WiFi Call Blocking Feature $0.00" added onto their features list
According to Apple, it should be everyone from 5c and on:
https://support.apple.com/en-us/HT203032
Just because the iPhone 5c and 5s are CAPABLE of wifi calling it doesn't mean that ATT is supporting those models. All of their information clearly states that they are not, for whatever reason. This isn't an Apple decision it's an ATT decision.
The reasons for support are both hardware and software related. ATT's WiFi calling has quite clearly been set up in a different manner that either Sprint or T-Mobile and depend on either HD Voice, VoLTE or both preferably to work to their best capacity as ATT intends in short older devices lack the tech.
It's unfortunate but it is what it is in this day and age tech be it computers smartphones etc become outdated in the blink of an eye. Perhaps point to societies tendency to push progress for the sake of progress and the ever evolving changing tech sector as a whole
