Xfinity Mobile is offering $400 prepaid Visa card to existing customers on any Samsung 5G phone purchase (except A71)
Note 20 preorders through 8/20 also get up to $150 Samsung store credit
Promotion runs 8/6/20 - 9/15/20, limit of 5 rebates per account.
Prepaid card rebate is only on upgrades for existing customers, but since no specific tenure requirement is mentioned,
new customers should qualify by opening an account (with BYOD, for example) and then "upgrading" as an "existing customer" few days later.
It may even be possible to combine this with $50 BYOD port-in promo for new customers.
Cheapest plan is $15/mo for Comcast customers.
