Xfinity Mobile Activate – Getting Started with Xfinity Mobile
For new Xfinity Mobile customers activating their mobile phone using their new phone number or current phone number can easily be done online at www.xfinitymobile.com/activate. The entire process is easy to do as long as you follow the instructions laid out here.

Steps to Activate Your New Phone Online
Before doing anything the first step to getting started is the unboxing of your new device. Unbox your new device including any other accessories that came with the device or that you ordered.
Other accessories could be your phone charger, SIM card, etc. Before activating your phone, make sure it is turned off.
The SIM card for your new iPhone must be inserted into the phone at this point.
The Xfinity Mobile SIM card mailed to you after you decided to BYOD (Bring Your Own Device) can be used with your existing phone. Insert your new Xfinity Mobile SIM card into your existing phone and eject your old one.
With Android, SIM cards are preinstalled.
You can also use Xfinity Mobile’s SIM labels to ensure no SIM cards get mixed up if you’re activating phones for the whole family.
