You can switch between a physical SIM and an eSIM, or replace your current physical SIM/eSIM with a new one, both before and after activating your phone number.

If you want to change your existing physical SIM or eSIM before activation, you can do so by visiting your Mediacom Mobile home page.

For changes after activation, contact our Mediacom Mobile Customer Care Team at 855-699-6655. A small fee and shipment cost may apply for changing SIM preferences. Ensure your Mediacom Mobile account is unlocked before initiating.

You will receive a time-based One-time Password at your registered email address. Provide this One-time Password to the agent. This step is crucial for verifying your identity and preventing fraud. Once verified, your SIM swap will be initiated.
