## Post context

Собственик пита кой сервиз сменя US модем с EU/глобален за LTE, каква е цената и има ли софтуерни проблеми след това.

## Answers from members

A similar job is being done on my car right now. When it is finished, I'll share more.

For a 2023 Model Y specifically, I was told there is a physical slot — so it can work with a mobile-operator SIM the same way.

Ще се наложи да смените модема. При версия 4 на хардуера е с Глобал модем и хваща lte без намеса.
