官网解释：
I used to be able to do a SIM swap online without calling customer care. It seems that's no longer possible*. You just need to get a replacement SIM and call customer service at 1(800)937-8997. You could go to a T-Mobile store and get this done. You can order a SIM-only online.
*This is unfortunate because I carry a spare SIM when traveling and if my phone was lost or stolen, I could do the SIM swap online by myself. Now, I have to be sure to have the setup to make a voice call, which can be expensive if abroad.
简单的解释下：
你先买一张新卡，然后给TMO的客服打电话，1(800)937-8997 让他们帮你把号码转移去新卡上面即可。
