In-store only, MetroPCS offers an Apple iPhone SE 32GB 4G LTE Prepaid Smartphone for MetroPCS for free when you switch carriers and adopt a MetroPCS Unlimited High-Speed Data Plan (starting at $50/month). That's the best deal we could find for this phone on any prepaid carrier by $160. It's also the first time we've seen an iPhone SE 32GB offered for free anywhere.
