how to disable SIM Activation Service in Xiaomi smartphones

Any operating system is a complex constructor, which contains a huge number of hidden and system processors.

Often, such system processors seem not obvious to users. We are trying to clarify and make them more accessible to the general public. The MIUI shell used on Xiaomi, Redmi, POCO smartphones has a built-in SIM Activation Service. In simple terms, this service is responsible for registering in the Xiaomi system to get some exclusive features. At the same time, SIM Activation Service does not affect the performance of your device and communication in any way – you can make calls and send SMS messages without it. Thus, SIM Activation Service is only an additional level of protection for providing access to personal information.

What does the SIM activation service give the user? For example, you can send messages via the internal Mi Messages system to other owners of smartphones running MIUI, free of charge and via the Internet. You will also get the option to save and sync your messages to your Mi Cloud account. Another useful feature is Mi Find Device (analogous to Find My Device from Google), which allows you to locate the lost device.

To activate the SIM Activation Service, you will need to send a paid SMS, so you must have funds on your SIM card account. If the user receives the message “SIM card is not activated”, then this only means that it is impossible to register in the SIM Activation Service, but for other tasks, his SIM card works quite correctly. This happens when you use your SIM card on a new Xiaomi device. If you want to turn off the annoying message about the impossibility of activation, then go to Settings> Applications> All applications> enter the word “Xiaomi” in the search field> select Xiaomi SIM Activation Service> turn off all permissions and completely limit the use of data.
