SMS Factory has relationships with the tier-1 carriers (AT&T, Verizon, etc.) and our agreements allow us to text-enable most business numbers, assigning the text routing to our SPID (Service Provider Identifier). We, via our resellers, validate that the owner of the number has given us permission to act as their text message provider. We then provision the number, so the customer can start sending and receiving texts. This process ensures safety and takes less than an hour.
