The Belgian Blacklist Mechanism requires companies to handle immediately process STOP opt-out messages sent by consumers.Operators: Proximus, OrangeBelgium, Base, Telenet, Lycamobile, NMBS, MundioMobile, ElephantTalk, Voxbone, JoinExperience, Unleashed" (these are all GSM services) We have direct access to a live MNP database in Belgium. "CM has a direct route in Belgium and direct connections to all Belgian operators. There were a few internet-hits linking Proximus and CM Telecom, but they were in Dutch so I'm not sure what they said :-) It is definitely the case that Proximus is connected to cmTelecom however =. However from what I can tel Proximus is NOT on the same backend as OrangeBelgium, they are a hardware-independent competitor.


It looks like MobileVikings is an MVNO of the OrangeBelgium network nowadays, so you could be experiencing the same STOP-of-cmTelecom-also-inadvertently-blocks-Twilio behavior in #8148.
