- For Android, install your two SIM cards. Because every model is different, you might need to check the manual. Then go into Settings > Connections > SIM card manager. You’ll then be able to select if you want to only use one card or both at the same time, and set the default SIM for calling, messaging or accessing the Internet. You can also assign one to each of your contacts in your phonebook.
- For iOS, if your iPhone supports eSIM, go into Settings > Cellular/Mobile Data > Add Cellular/Data Plan and scan the QR code that was provided to you by your new operator or tap Enter Details Manually.^{[4]
