What 5SIM is
5SIM is a marketplace for single-use virtual phone numbers used to receive SMS verification codes, with prices advertised from $0.008 per number and new numbers added daily. The site describes use cases such as keeping a personal number away from data brokers, receiving local SMS while travelling and testing SMS flows in development. Buying a number requires logging in or signing up for an account. The pages read for this review do not list the accepted payment methods or describe any identity requirements, so those fields are left empty; users should check the top-up options inside an account.
