Roaming
When I did the automatic installation using the QR code, I clicked on the primary chip and selected it as secondary. Then I clicked on the eSIM where it said secondary and switched to the primary option just so I knew which one I had was the one I had to use since I'm outside my country and it would charge loads of money if I used roaming from the operator where I live. Today, after 10 days, I discover that something went wrong and I was using the wrong SIM card roaming. However, customer service, even after a long conversation to try to understand where the problem was, managed to help me and resolve it by WhatsApp! And now I’m F!ck to pay what will appear on next month's bill for my official number!
