Can i buy a redmi note 10 s on aliexpress and activate it on tmobile and use it without dropped calls and get 5g?

Phones don’t require activation on the T-Mobile network!  You simply just put your SIM in the device and if it is SIM unlocked and supports the bands and software needed (very crucial) to connect to the T-Mobile network.  Then it will work.  VoLTE is pretty much mandatory for devices to make calls over the T-Mobile network.  T-Mobile uses the same profile for its services that Google does, which is the Android standard.  Companies like Verizon, AT&T, and many others around the world, choose to use different profiles for VoLTE and WiFi Calling services, which make those services not function on T-Mobile.  

Looking at the supported 4G bands for the Redmi Note 10.  You won’t have a very good experience.  T-Mobile uses bands 2, 4, 12, 41, 66, and 71.  Pretty much any deployment in the past more than half a decade has focused on bands 12, 66, and 71, all of which, the Redmi Note 10 does not support.  Xiaomi Redmi Note 10 - Full phone specifications (gsmarena.com)
