T-Mobile launches eSIM for postpaid customers, but there's a catch4
However, there's a catch, and many T-Mobile customers might not like it. Neither the announcement nor the FAQ mentions any Android smartphones when it comes to eSIM support. For the time being, T-Mobile will offer eSIM support to postpaid customers who own an iPhone XS, iPhone XR, and iPhone XS Max.
If you own one of the compatible iPhones mentioned above, you can visit a T-Mobile store nationwide starting August 28 to have your eSIM set up. It doesn't even matter if you're an AT&T, Sprint or Verizon customers, as the eSIM will allow you to get T-Mobile on your iPhone.
In case you didn't know, the eSIM is a digital SIM that's built into your phone, which can be activated with your account information rather than inserting a physical SIM. Apart from new iPhones, just about every Pixel smartphone starting with the Pixel 2 features eSIM support, but they don't appear to be supported by T-Mobile yet.
