Some of these requirements aren’t even from Twilio but from upstream, Tier 1 telcos. T-Mobile for example has made many changes over the past few years intentionally designed to make it harder to onboard large numbers of texts, and they’re happy to tell intermediaries like Twilio to get fucked if they don’t play ball. Which in absence of any stronger measures is great, but those stronger measures could at least serve to create a baseline that’s the same and reliable across the industry. If you want to launch a 10DLC-based campaign it can be a real headache.
