> Would it be easier if I just built this service in-house (SMS and phone number validation)? If you have to ask, probably not. Ultimately when you’re dealing with large companies like this, you’re constantly being watched by algorithms to see if you’re doing anything remotely spammy. They suspend first, ask questions later. This is not a Twilio-specific policy; you’ll see it with payment processors, social media services, and more. If Twilio doesn’t act fast to prevent potential spammers, the FCC would get really stern with them, so they have to play it safe, even at the risk of annoying their paying customers. Three hours is also not that much time when it comes to this sort of thing; some platforms take a few days, since humans need to look over what you submit.
