Getting Started

Whether you are a new customer or adding a line to your existing account, here’s everything you need to know to set up your phone and activate your service.

Set up your phone

We offer detailed step-by-step instructions for each major phone manufacturer to help you set up your phone

If you brought your own phone (BYOD), you need to follow the steps in the sections below — but first, you must make sure your phone is unlocked. If you haven’t already unlocked your phone, start by connecting with your previous carrier to make sure it gets done.

Connecting your phone to Wi-Fi and enabling Wi-Fi Calling will improve service quality and help you save data. You may also need a Wi-Fi connection to activate your phone.

    • eSIM customers must connect to Wi-Fi to activate their service.
    • Physical SIM customers can access MyMobile from another device to follow the activation steps and skip this Wi-Fi connection step.

Make sure your phone has the most current operating system (OS) installed. We support iOS or Android with step-by-step guides to update your phone. Even after activation, we recommend installing your system updates to help you get the best service—and so we can provide the best support.

Transfer your number

If you want to transfer (port-in) your number to Optimum Mobile, you will first need to provide some information about your previous carrier. Once the port-in is complete, your service with the previous carrier will be canceled automatically.

Please note: If you cancel service with your previous carrier before we complete the transfer, you will lose your number.

You can either choose to transfer your number during your purchase or at a later time.

    • If you opt to transfer your number at the time of purchase, we will send you instructions on when to complete the transfer.

Activating your service

When activating a new number, you need to sign in to MyMobile to complete activation.

    • If you have a physical SIM card: make sure it is inserted into the phone you want to use, whether it’s your new phone or a phone you’re bringing over to Optimum Mobile. Then, use our guide to walk through the steps to activate service. Once you insert your SIM card, accept the Carrier Setting Update (required).
