"SCL UNL TT FAM 4 Lines incl"

We have Simple Choice plan. My son bought a 15GB International Data Pass but could not use it. I noticed “"SCL UNL TT FAM 4 Lines incl" $100/mo in the Add-Ons.

    It should be under Settings, Cellular, Cellular Data Options.  Data needs to be on for roaming for VoLTE to work, which should allow calling to work.

Settings -> Cellular -> Cellular Data Options -> oggle Data Roaming ON
