Shifting contacts between Xiaomi smartphones is a challenge that every user faces when buying a new device. Even if both phones run on MIUI, the process can be difficult due to differences in firmware versions or lack of synchronization. Redmi 9T (model M2010J19SG) supports all standard data migration methods, but some require pre-tuning.
In this article, we will analyze 5 proven methods of transferring contacts - from automatic synchronization via Mi Account to manual export via vCard. Particular attention will be paid to the nuances that arise when working with Redmi 9T: the limitations of the version of MIUI 12/13, the features of the Snapdragon 662 chip and compatibility with SIM-cards of nano-SIM and micro-SIM formats (via an adapter).
