🚫 Do not reset the eSIM profile

A deleted or previously installed eSIM may not be reissued.
Activation and Usage
We recommend installing the eSIM before departure while connected to stable Wi-Fi.

📶 Turn on the eSIM line
📱 Select the eSIM for mobile data
🌐 Turn on data roaming
🔕 Turn off data roaming for your original SIM
🔄 Restart your phone if the network does not connect
Installing the eSIM before departure does not normally begin the usage period. The plan generally starts after connecting to a supported network at the destination.
