Hello, does T-mobile in America have an international SMS package? I just want to send and receive short messages from America at home, that's all.

Most domestic mobile phones can receive short messages from the United States, with no restrictions and no special packages;

When you say T-mobile roaming, it seems that you want to use the American telephone package at home, so you can start roaming internationally. I haven't used the specific text message. I hope it helps you.
