Frequently Asked Questions
How does SMSKap ensure WhatsApp and Telegram do not ban virtual numbers?
Unlike typical VoIP providers that assign data center IP numbers, SMSKap provisions genuine physical SIM hardware registered directly with Tier-1 wireless carriers in the UK (+44), USA (+1), and Turkey (+90). Meta and Telegram verification algorithms detect genuine mobile network prefixes, preventing automated bans.
What happens if my verification SMS OTP does not arrive?
If the 6-digit SMS code is not delivered before the countdown timer expires, our system automatically cancels the transaction and refunds 100% of the funds back to your wallet instantly.
Can I use these virtual numbers for WhatsApp Business?
Yes. Our UK (+44) and USA (+1) physical SIM numbers are fully compatible with WhatsApp Business, allowing you to set up official business profiles, automated greetings, and product catalogs.
