StealthSIM, NextSIM, “Bladox”-SIM, Which one works with Baseband 04.03.13_G

I am seeing different postings on EBAY of people selling SuperSIM and NexSIM cards that claim they can get a signal with Phones that have the iPhone modem Firmware-Version 04.03.13_G (1.1.3) – can anybody confirm these rumors?

Thank you for your Feedback.
