Does iPhone support DUAL eSIM

You can use Dual SIM by using a physical SIM and an eSIM. iPhone 13 models and later also support two active eSIMs. iPhone models without a physical SIM tray support two active eSIMs.

If you already have an eSIM from your home country, and your iPhone is from before iPhone 13, you have 2 options:

1) You can disable your home country eSIM, and use Bikago Mobile eSIM

2) You can request a physical SIM card from Bikago Mobile. This way you can keep using your home country eSIM for phone calls and SMS, but use the Bikago Mobile physical SIM card for internet data while you are in Bali and Indonesia.
