Resolution Playbook: VOIP Carrier Bypass Protocol

1
Switch to a physical Tier-1 mobile SIM: Promo activation endpoints explicitly query Twilio/Telesign Lookup APIs for carrier line type. Virtual numbers (Google Voice, Skype, VoIP.ms) are automatically dropped to prevent promo abuse.
2
Initiate Shortcode Handset Unblock: Text START or ALLOW to 24444 or 83224 from your mobile device to clear carrier anti-spam filters.
3
Request Support Manual Override / Auth Link: Escalations can be submitted to billing support with this diagnostic log attached to issue a direct tokenized activation magic link.
