Unfortunately, Xiaomi phones are GSM only and won't work with CDMA carriers like Visible, Verizon, US Cellular, and the like. I recommend getting a physical SIM card from Mint Mobile or some other GSM MVNO, which will be a cheaper option than AT&T or T-Mobile postpaid. That way, the student can use their same phone and not have to purchase another phone. Good luck to you!
Thank you for this idea. I put in my address at Mint and it said that coverage for my address is "fair" which makes me a little nervous. I wonder if fair is good enough or if we will end up regretting that.
If you have an old phone, you could do the swap for this phone:
The swap would be free if the old phone meets Visible's requirements.
