I am staying in Japan now and I got bars (docomo).
I visit Japan often and last time I was here 4 months ago, there was no roaming so it looks like they started it recently. I actually do not want to use roaming and I turned the data off. However the bars are still there and I got a call from a Ontario number(where I’m from, but I don’t recognize the number). There is a voice mail message too. I did not apply for “easy roam” etc. so I wonder why I get a call. My questions are
(1) why do I get calls from Canada and how much does it cost if I pick them up, and/or listen to voicemail?
(2) how can I entirely turn off any kind of incoming calls? My phone is very private and anyone who knows my number knows I’m out of the country and I want to shut off all the calls. My phone is IPhone 6s and I cannot find any settings for this except cellular data off, which I had already done before getting the call.
