Can I use both Nano sim and e-Sim? SIM cards did not always come in the tiny chip formats that we have nowadays. Most current mobile phones and mobile devices that use SIM card technology nowadays use a Nano-SIM slot.
A SIM card is basically a card with an embedded chip that is inserted into your mobile phone. Apple introduced this concept of nano-sim with the iPhone 5 which was the first phone to use the Nano-SIM sized card, in 2012.
Can I Use Both Nano Sim And e-Sim?
An eSIM, as opposed to a physical SIM card, is a SIM that’s already embedded into a device. If you have a dual SIM device with an active plan on a physical SIM and on an eSIM you can use both plans at once by allowing your device settings to select which plan you want to use when making calls, sending texts or browsing the internet using data. If you’re actively on a call using one of the plans, any calls directed to your other SIM will be redirected to your voicemail.
However, you’re using an eSIM but your phone does not support dual SIM service, you have to make sure that physical SIM is ejected from your phone to allow the eSIM to operate.
