Introduction

If you love having the latest phone technology and if you get your phone service from Xfinity, then you're in luck. Xfinity not only makes it easy for you to upgrade your phone, they make sure you can do it often.

What You'll Need

If you have Xfinity's Mobile Plus or Premium Unlimited plans, you can upgrade your phone anytime you like, as long as it's been at least 60 days since your last upgrade.With other service plans, you can also upgrade once every 60 days, but only if you have paid off 50% or more of what you owe on your current phone. Your Xfinity account must also be in good standing, you must buy your new phone from Xfinity, and your old phone must be returned to Xfinity and also must be in good working condition.Make sure you remove all of your personal information from your old phone before you return it. Read your owner's manual for more information on how to do that.The fee for an early upgrade of an iPhone is $30. Upgrading a Motorola or Google phone early carries a $50 fee. Upgrading a Samsung phone early comes with a $70 fee.If you are enrolled in XMC (Xfinity Mobile Care) then you won't have to pay any early upgrade fees.

Why does GetHuman Write How-to Guides for Comcast Problems?

GetHuman has been working for over 10 years on sourcing information about big organizations like Comcast in order to help customers resolve customer service issues faster. We started with contact information and fastest ways to reach a human at big companies. Particularly ones with slow or complicated IVR or phone menu systems. Or companies that have self-serve help forums instead of a customer service department. From there, we realized that consumers still needed more detailed help solving the most common problems, so we expanded to this set of guides, which grows every day. And if you spot any issues with our What do I do if my Xfinity TV or internet is out? guide, please let us know by sending us feedback. We want to be as helpful as possible. If you appreciated this guide, please share it with your favorite people. Our free information and tools is powered by you, the customer. The more people that use it, the better it gets.
