Question about LTE settings on iPhones

[aces99]

I have a question about LTE settings on a iPhone. If I go to “Settings” then “Cellular” then “Cellular Data Options” and click on “Enable LTE” there are a couple different options to choose from. There is “Voice and Data” and “Data Only”. Right now it is set to “Data Only”. But under the different options it says “Using LTE can load data faster and improve voice quality”. What is the best option to choose. Should it be set to “Voice and Data” or should it just be set to “Data Only”?

It should be "Voice and Data." Most (perhaps all) of the Canadian carriers support Voice over LTE (VoLTE), which will allow you make calls over the LTE network as well as the switched network.

You didn't say which carrier you're using, but here's Telus' explanation of why you want VoLTE:

and here's Rogers':

I am on Telus. But it was set to “Data Only” I wasn’t sure if a person set it to “Voice and Data” that it might use a lot more of your cellular data and might make it more expensive using the voice and data setting.

That's a common misconception. In the Telus reference I gave, it says:
"There are no additional fees for using the VoLTE service and does not use any of your allotted data."

As far as I know, this is true of all North American carriers.

In poor reception areas I switch my LTE to data only and the phone gets better reception for calls, this is on Verizon and in areas where there is really bad service

What about the option that says “Wi-Fi calling on this iPhone” Should this option be enabled or not? I am not sure what the advantage would be to make and receive call over Wi-Fi compared to the regular way.

If you have a poor cellular signal or perhaps no cellular signal then being able to make or receive calls via WiFi would be useful. It's all more or less fairly straightforward.

WifiCalling also enables you to make phone call outside your country and not be on roaming, as it uses Internet until the servers of your supplier.

That's only true on some carriers. The OP’s carrier, Telus, blocks Wi-Fi calling and messaging outside of Canada.

Thanks for all the information. Yes my carrier, Telus, blocks Wi-Fi calling outside of Canada. Which is kind of a bummer.
