Your post made me try one more “free GPT-4” site and again, hit the SMS wall. Needed a number that works for both the AI portal and a backup email. Used 7sim.cc/en, took a Canadian +1 phone number (real SIM, not VoIP). First code in 60 sec, second in 2 min. Didn’t buy a SIM, didn’t expose my real number. Clean, fast, and actually got past the signup even if it’s still GPT-3 under the hood.
