I went towards the 'My Tello' account, then for the 'My SIM' portion. There, I discovered a QR code, which I scanned with my camera, in addition to a new 'eSIM2' document appeared in the 'Sim manager' beneath the 'eSIMs' portion (I have already got 'eSIM1' with a different enterprise). https://crossw222ytn6.wikinstructions.com/user
