If you bought your IQOS device in Hungary, in a national tobacco shop that sells IQOS devices, and you did not register in the tobacco shop, you can register yourself and your device as a new customer on the website www.iqos.com. Under certain conditions, you can also start the registration of an IQOS device purchased abroad here. More information:
