We're planning to travel to Europe later this year and would like to take advantage of T-Mobile's free international text/data roaming. However, I saw that incoming calls are charged at one minute even if you don't answer; per T-Mobile's website: "If your phone is on when you get an incoming call, even if you do not answer it, the call is charged one minute for delivery to the phone. (There are no charges if your phone is turned off.)" I get multiple robocalls/telemarketer calls per week, and I don't want to rack up charges for unwanted calls. Is there any way to temporarily turn off incoming calls or route them directly to voicemail to avoid charges? If so, what are the steps to do that?

Great question. The easiest way to do this is to enable unconditional call forwarding. This will tell the network to immediately forward the call to a selected number without trying to pin you first which is where the charge comes from.
To enable unconditional call forwarding, you will need to follow these steps https://support.t-mobile.com/docs/DOC-4041#secondheading
Dial **21*18056377249# from your phone to enable CFU and ##21# to turn it off when you are back in the states and want to resume being able to get calls.
The 18056377249 number is the same number that your calls are forwarded to when you do not answer the phone so that the people calling you can leave a VM. Since we are enabling unconditional call forwarding, the call will be automatically routed there instead of ringing your phone first.
