Is Apple Watch available on any prepaid plans yet? I'd love to use the cellular model for its intended purpose of reducing phone use but there seems to be no affordable options, at least in the US. E.g. the prepaid T-Mobile Connect plan costs $25/mo, whereas the cheapest postpaid plan with T-Mobile that includes the watch surcharge comes out to $60-70/mo and is on worse terms.
