问了一下charGpT， 第一条推荐也是prepaid When it comes to selecting a cell phone plan for a high school kid, there are a few factors to consider, such as the cost, the amount of data, and the coverage area. Here are a few options to consider: Prepaid plans: Prepaid plans can be a good option for high school kids because they are typically cheaper than traditional plans and provide a set amount of data that can be used each month. This way, kids can learn to manage their data usage while still having access to a phone for emergencies. Family plans: Many carriers offer family plans that allow multiple lines to share data and minutes. These plans can be a cost-effective way to provide a phone for a high school kid while also providing service for other family members. Unlimited data plans: If the high school kid uses their phone frequently for streaming videos or playing games, an unlimited data plan might be a good option. These plans allow for unlimited data usage each month, so there's no need to worry about overage charges. Pay-as-you-go plans: Pay-as-you-go plans are another option that may work well for high school kids. With this type of plan, users pay for minutes and data as they go, so there's no need to commit to a long-term contract. This can be a good option for kids who don't use their phone very often. Ultimately, the best cell phone plan for a high school kid will depend on their individual needs and usage habits. It's important to do some research and compare plans from different carriers to find the best fit.
背景：家里的大小孩要给她搞个手机。
我自己以前的sprint老计划很合算，被tmobile 收购后，还保留税后30块的好价格。我问电话公司，被告知我这个plan不能加人。只能换plan 说我和小孩两条线90+tax，大概100块， 我觉得小贵。后来得知我还有个小孩，说索性3条线也是同样价格，90+tax=100。 签约2年的话， 新iPhone 50% off.
我觉得这个plan还行。但是小娃还在小学，貌似平时不需要手机，一个smart watch应该就够了, 不需要data, 好像也不需要加一条线？
还有，我在电话上的时候，rep说他可以自己给我定。我不需要去店里。听着蛮方便，这样可靠吗？
谢谢提议！
我对新手机也没感觉，只是因为小孩手拿不住东西似的，刚刚把电话摔烂了，我觉得修起来可能不会便宜，所以想买一个新的。当然，也可以把我的手机给她，我用新的。
mint听上去很合算。我去研究研究。

刚刚看到是$15/月，3个月后得续约6个月或一年的. mm的好deal是不是可遇不可求的？

真便宜，我刚刚看了一下。 8刀这个没有data
如果以后想转出容易吗？知道有的公司进去容易出来难，找不到客服，好不容易找到了，各种麻烦转不出。
Tello 转进转出很容易，自己账户里操作一下就可以看到转出需要的账号，自己设转出需要的pin。data偶尔不够用的话，也可根据需要随时买新plan。不怕麻烦每个月到期前操作一下换plan的话，剩余data和通话时间可以累积到下个月。具体规则可以看官网的faq。
我几年前用tello，中间转到其它公司一年拿promotion，不久前又换回tello，喜欢它的灵活价廉，下次有其它公司好deal的时候可以再转出去。
