Why not use a free online SMS site?
Free shared SMS inboxes are publicly readable — anyone can see the codes sent to those numbers. Every major platform (WhatsApp, Google, Instagram) has already flagged the entire number ranges used by these free sites and will reject them.
VRNUM OTP numbers come from real licensed mobile carrier allocations. They are not flagged as VoIP or shared-inbox ranges. Your assigned number is private — only your VRNUM account can see the incoming SMS.
