5 Important Things You Must Know

  • 1. OTP didn't arrive? Balance auto-refunded. Wait until the number expires (15 min) or click Cancel after 2 minutes. 100% refund. no need to contact support.
  • 2. Numbers active for only 15-20 minutes. After that, automatically released and balance refunded if unused.
  • 3. Deposit confirmed within 1-5 minutes. If longer than 5 minutes, refresh dashboard or wait. usually just a bank confirmation delay.
  • 4. DO NOT share numbers with others. Virtual numbers are for your personal use. Sharing = privacy risk + others may use your number too.
  • 5. 1 number = 1 platform. Want to register WhatsApp + Telegram simultaneously? Use the Multiservice feature on Server 2 (see Server 2 section below).
