After completing your purchase, you will receive a QR code via email. You can either print the QR code or open it on your computer. Next, on your cell phone, navigate to Settings > Mobile/Cellular Data > Add Data Plan and scan the QR code. Your phone will prompt you to assign a specific name to this data plan. Once configured, you can seamlessly switch between your RUGO data plan and your original plan from your provider. Please note that the RUGO data plan will only become active upon reaching your destination. Upon arrival, enable data roaming in your cellphone settings and activate the RUGO data plan. For detailed instructions on adding a data plan, consult your phone's user manual. Additionally, each eSIM product includes comprehensive setup instructions.
