It says the eSIM can't be added again

An eSIM can only be downloaded once. So if you try to install it a second time, the phone (or the install link) says it failed or "can't be added".

That almost always means the first install worked. The eSIM is already on your phone, just not switched on or not connected yet.

Find it

• iPhone: Settings → Mobile Service. Look for a line called kimsim, Travel, Business or Secondary.
• Android: Settings → Network & internet → SIMs (Samsung: Connections → SIM manager).

Switch it on

1. Make sure the line is turned On.
2. Restart the phone.
3. Choose it for Mobile Data and turn on Data Roaming.

If the Mobile Data option is missing on iPhone, follow this guide.
