1. Real SIMs vs. VoIP Numbers: Avoiding the Carrier Filter

Major tech platforms employ real-time carrier lookup APIs (Twilio Lookup, Telesign) to inspect the line type of incoming phone numbers. Virtual numbers derived from cheap VoIP trunks (Google Voice, Skype, bandwidth aggregators) are immediately rejected with the error: "This phone number cannot be used for verification".

Nolimit SIM integrates exclusively with physical SIM card pools and Tier-1 non-VoIP cellular carriers (T-Mobile, AT&T, Vodafone, Singtel), ensuring 100% acceptance rates across all tier-1 platform compliance gateways.
