对于我来说我觉得最大的问题是。
如果我在AT&T用trade in 旧手机 iPhone 12 and up get up to $1000 bill credits in 36 months
如果提前付清了financed amount，那么bill credit就不会继续apply
所以如果我付清了但是T-mobile不认K&S就很难受
而且略有一些折腾，要自己先付清然后再找T拿reimbursement
就等于有shit hit the fans 的几率
4条线 4x800+ 的前期risk
等于本来分成三年拿回来的credit可以让T-mobile一下子提前拿回来
但是又有什么用呢
美版没有卡槽解锁了带回国也用不了
再加上还有iPhone 13/PM, iPhone 15PM, Samsung S22+ 等等等的备用机
还有移动的无忧行
我觉得有没有卡槽已经没有那么重要了
最完美的可能是以下方案
去AT&T Costco 开户 port in new lines + finance手机(trade in) = 100 Costco Shop Card + 300 bill credit
三个月后付清尾款 申请解锁
再去T-mobile Costco 开户 K&S promotion, 再拿一波reimbursement + VGC(Costco)
然后关户走人 但是很鸡飞蛋打的感觉
毕竟我现在的AT&T 加上税一条线也就差不多27刀左右
三大运营商最便宜的也不过如此了
还在用AT&T天天刷付款次数
跟它搞好一点关系也不错
除了一个自己的Google fi的号码，剩下三个号码都是number barn买的，希望两年之内没有被用过
如果只是普通开户t-mobile的话也许网上能自助
