☎️ You're using phone number verification to protect your app or service from bots and scammers? You do well! But here's the thing: obtaining disposable phone numbers to receive one-time passwords (OTPs) is quite easy. Numerous websites out there provide free virtual phone numbers solely for the purpose of receiving OTPs and bypassing phone number verification. This essentially makes your efforts ineffective.
