Where to find eSIM
| Phone | Menu |

Install with a QR code
Connect to wifi
Open the QR code on another screen, for example a computer.
Open the eSIM menu
Open the menu for your phone from the table above and choose to add an eSIM with a QR code.
Scan the code and confirm
The phone downloads the eSIM. Give it a name, for example Reissaa. If scanning fails, choose to enter the code manually and type in the details from your order message.
Leave the data line for later
Do not switch the data line yet if you are still at home. Check the plan details to see when validity starts.
When you arrive
Turn on the Reissaa eSIM
Open the SIM settings and switch the eSIM on.
Select it for mobile data
Find Mobile data or Preferred SIM and choose the Reissaa eSIM.
Turn on roaming
On a Pixel, open the eSIM settings and turn on Roaming. On a Samsung, it is under Settings → Connections → Mobile networks → Data roaming.
Keep your own number for calls
Your own plan can stay on for calls and messages. Once the Reissaa eSIM is selected for mobile data, your own plan's data is not used. If the settings have a separate Data roaming option for your own SIM, keep it switched off.
