Get $300 per line when you switch

Hello, @user_rc9wc7. Thanks for posting on our community forums. Upon reviewing our 2023 Xfinity Mobile promotions, I only see one offer that matches the $300 price you are referring to: 

 

$300 off select Samsung devices
New and current Xfinity Mobile customers can qualify for a promotion worth $300 off the price of select new Samsung devices.

The following phones are eligible:

• Samsung Galaxy Z Flip5
• Samsung Galaxy Z Fold5
• Samsung S22 series (S22, S22+, S22 Ultra)
• Samsung S23 Series (S23, S23+, S23 Ultra)

Note: The Samsung A series phones and S22FE are not included in this promotion.

Current customers must either:

• Purchase a qualified device with a DPP on an existing line of service, or
• Purchase a qualified device add a new line of service and port an existing phone number from another carrier within 30 days of purchase.

New customers must:

• Activate a new line and port an existing phone number from another carrier within 30 days of purchase.
  
  

The promotion will be delivered to the customer in the form of a monthly bill credit spread over 24 months.

Based on the promotion end date, it looks like you would not qualify for it. Is this the offer you are referring to?
