International roaming has been opened. Can I answer calls and text messages with my mobile phone? Can I make and receive domestic calls and send and receive text messages with Xiaomi mobile phone when traveling to the United States? Excuse me, which Xiaomi mobile phone are you using? If it's mobile TDSCDMA, I'm afraid not, as long as it's WCDMA and CDMA2000 in the United States. Mobile phones can only use GSM 2G network. Unicom system is no problem.

Now there is Xiaomi roaming, which is virtual and can be used without changing the card. It is suggested that the landlord open Xiaomi roaming. Not expensive either.
