Incoming calls while abroad
I am going to India, but will need my mobile number to receive calls from the USA. I have a couple of questions - Will the person calling from the USA be able to call me normally, and will he/she be charged extra for the call? If I receive the call, what would I be charged? If I keep my phone on airplane mode and connect to wifi, will wifi calling work (wifi calling is free as far as I understand)? I am on the ONE plan (family plan) without any add-ons as of now.
International Roaming & Rejecting Incoming Calls
If I'm out of the US traveling and someone calls me and I don't answer the call will I be charged? If that person leaves a voicemail and I don't call to check my voicemail would I be charged? If so, if I disable voicemail would it avoid me getting this charge? Or do I have to disable voicemail and remove call forwarding? There seems to be a lot of conflicting information about this. I spoke to a few T-mobile reps and some say I won't get charged and others are saying I will get charged regardless. So I honestly do not know who/what to believe! Any tips would be appreciated.
