To call and text with an eSIM, follow these steps:

Using Your Regular Number: If you have an active primary SIM, you can continue using your regular phone number for calls and texts. Just ensure your primary SIM is enabled on your device.

Using iMessage and Apps: If you’re using an iPhone or iPad, you can send and receive iMessages over Wi-Fi or mobile data, even without a traditional phone number. For other messaging options, you can use apps like WhatsApp, Messenger, or similar platforms.

Remember, when traveling internationally, check your roaming settings to avoid unexpected charges.
