If I’m traveling to another country, I might want a local number so that people in that country can call me from without incurring a long distance call charge.

Also, a lot of 2 factor verification systems have trouble messaging international numbers. A lot of the airport Wi-Fi’s I try to log into, for example, almost never succeed in sending me a pin on my international number.

Adding a roaming data plan to my existing number only solves a small number of the problems international travelers face. And even those problems are almost always resolved at a higher cost than getting a local SIM.

Yea I have T-Mobile as well and like it quite a bit. Even if very few customers took advantage of this offering it gives you a sense of safety that taps into the same nerve center that something like the Amex Platinum and lounge access does.
