I am in Brussels for few days and the roaming service is a nightmare, slow, does not respond and I tried to join Proximas 4G or reset the network and now even my normal line does not work.. it is not a service standard I could accept. All the networks are Forbidden.
Have you got roaming activated, on your online account as well as on the phone. That needs to be set for roaming to work. Did you get a welcome text on arrival? And what colour sim card do you have, vm have issued new purple sims since December 2017. If you have the purple sim, you can check/amend the setting.
