T-Mobile and Google both do it in 215+ countries for unlimited basic data (not 5G). T-Mo charges between $75/mo for that and $90/mo for 5G data internationally (not unlimited). Google charges $35/mo with unlimited data (doesn’t guarantee 5G). It’s not difficult for them to do or even expensive. Most just choose to make it more expensive.
