Open your Galaxy’s Settings, then Connections and SIM manager to add the eSIM using the activation details supplied for your Previ line. After installation, choose the intended line for calls, messages, and data.
Have the activation details ready
For a new Previ line, the onboarding team helps with the number transfer and sends an activation link or QR code by text. Start with that message when it arrives.
Connect the Galaxy to Wi-Fi and have the instructions for the intended line available. The steps below show a Galaxy S25 QR-code route. Use it when a QR code has been supplied for your line; menu labels can differ on other models.
Open the eSIM settings
- Open Settings, then Connections.
- Select SIM manager.
- Select Add eSIM.
Install the supplied plan
- Choose Scan QR code and place the supplied code inside the camera frame.
- Continue through the downloaded-plan prompts until the preferred-SIM choices appear.
Choose the line for calls, messages, and data
If more than one SIM is available, choose the line you just installed for the services you want it to handle. SIM 1 and eSIM 1 are example labels; identify your own line before making the selection.
- On Preferred SIM for calls, select the intended line and tap Next.
- On Preferred SIM for messages, select the intended line and tap Next.
- On Preferred SIM for mobile data, select the intended line and tap Done.
If there is no QR code or the plan does not download
Contact Previ support with the line and Galaxy model to confirm the right installation route. Do not purchase another plan from an unrelated setup prompt to finish your Previ activation.
Check that the intended line works
After setup, make a call and ask someone to call your number. Send a message and check that you can receive a reply. Briefly turn Wi-Fi off and load a page to check cellular data, then turn Wi-Fi back on if you normally use it. If the phone has two lines, use the number you just activated for these checks.
If a check fails, contact Previ support with the number, phone model, and the test that failed.

Here’s how to activate your Samsung Galaxy with eSIM.
Connect your Galaxy to Wi-Fi and have the activation information Previ sent for your line. This example follows the Galaxy S twenty-five QR-code route. Other models may use different labels.
Open Settings, then Connections, then SIM manager. Select Add eSIM.
Choose Scan QR code and scan the code supplied for this line. Follow the downloaded-plan prompts until you reach the preferred-SIM choices.
Choose the intended line for calls and tap Next. Choose it for messages and tap Next. Then choose the line for mobile data and tap Done. Match the selection to your own line, not just the example SIM label.
If you have no QR code or the plan will not download, contact Previ with the line and Galaxy model. Do not buy an unrelated plan to finish this activation.
Test calls in both directions, a message and reply, and cellular data with Wi-Fi briefly off. Use the line you just installed. If something fails, tell support which test and phone model are involved.
Use the steps for your own line and device. If the screen or result is different, contact Previ support with the message you see.
