Iran: Fuel company claims refueling video shows misuse of smart fuel card chips, not SIM cards Iran's National Petroleum Products Distribution Company said its investigation found the video, which showed SIM card bodies being used for refueling, had nothing to do with SIM performance or the cellular operators' network. Some of the profiteers separate smart fuel card chips and install them on SIM card bodies, when refueling is done through the chip itself. The company manages the issue with the relevant parties.
