Can my working sim card in a idol 3 be put in a idol 4 and work?

Hi, Unfortunately NO it won’t. The SIM card from the Idol 3 is too big to fit into the Idol 4. An Idol 3 uses a micro SIM card. An Idol 4 uses a nano SIM card. SIM cards come in three sizes: Standard SIM (15 x 25mm)Micro SIM (12 x 15mm)Nano SIM (8.8 x 12.3mm *
