What is JoltSMS?
JoltSMS gives your team dedicated, long-term U.S. mobile numbers (real-SIM, not VoIP) to reliably receive one-time passwords (OTPs) and account security codes from services like Apple, Google, Microsoft, Instagram, and more. Numbers are rented month-to-month and can be shared safely with teammates.
