Free SMS OTP Blockchain Questions
How can I get a free SMS OTP for Blockchain?
Sign in to GetSimOtp and select Blockchain. If a free OTP promotion is available for your account, service, and selected country route, eligibility is applied during number allocation. Live availability can change by operator.

Use the controls and timer shown with your active order. Order status, cancellation rules, and any applicable refund remain controlled by the existing GetSimOtp order system.
