Hi Vanems,
Thanks for your post and welcome to our community.
Very sorry to hear that you've having an issue receiving calls in Brussels, this ins't what we like to hear.
Can I ask if you're able to use all other services, can you send and receive texts, is data working?
Can I ask what network you're connect too in Brussels?
Let us know so we can help further 🙂
