Confirming previous rumors, the no-contract carrier Cricket Wireless is currently selling Microsoft's Lumia 650 phone with Windows 10 Mobile for free for new customers who switch their old phone number from any carrier other than AT&T. The phone is priced at $49.99 for all other buyers.
Both the free and $49.99 offers for the Lumia 650 come with a one-time activation fee of $25, although our tipster indicated that some brick-and-mortar Cricket Wireless stores could wave that fee. This offer is for a limited time "while supplies last" according to the carrier. Keep in mind that getting the phone from Cricket will lock the user with the carrier for six months before an unlock code can be sent to the phone. That code can also be provided if the customer signs up for the carrier's $70 unlimited plan for one month.
