How To Fix Xiaomi Sim Activation Service

Last Updated on March 24, 2022 by Ramon Walters

What’s the first thing that we do after buying a Xiaomi device? Set up the sim card, right? But what if you cannot set it up and an error message is shown? It’ll be undoubtedly frustrating.

But there’s a reason why you cannot setup your sim in Mi devices. The reason behind this is device security. Due to this, sometimes, the manufacturers use this method to ensure the Mi device’s or user’s safety. But almost in all cases, it backfires!

So if you’re one of them who is facing the issue of setting up a sim card in their Xiaomi device, then you’re welcome. Here, we’ll talk about the common problems related to Xiaomi Sim Activation Service and solve them.

Sim Card Activation Failed in Xiaomi Devices: Why it Occurs?

Initially, you might end up thinking this sim card error issue is a hardware problem. But trust me, it’s not. It’s more of a software issue from the very own Xiaomi phone manufacturers. But why’ll they do it on their own device? Well, that’s what we’re gonna talk about in this part.

1. Using Invalid Sim

Before we insert a sim into our Xiaomi device, you need to verify it first. It’s seen that, in many cases, people use invalid or expired sim cards. As a result, the Mi devices cannot read them. And ultimately, a Xiaomi Sim Activation Service is shown.

Considering this, you should always check if the sim card is valid or not before inserting it into Mi devices. If there’s a problem, contact the sim companies. It’s not the fault of Xiaomi devices or the manufacturer’s side!

2. Inserting Damaged Sim

This is another common phenomenon that’s seen often. When we use a specific sim card for years, it can easily get damaged. Moreover, the sim can be damaged while inserting them on the devices as well.

So when you’re using a damaged sim in your Mi device, it’s quite common that the device will not be able to detect it. So every time you insert your sim or try to remove it from your device, be careful so that you don’t damage it.

3. Security Issue

Unlike the other two reasons, this is a fault or issue from the Mi phone manufacturers. The Xiaomi devices are sent globally and used by people across the world.

Often manufacturers add “EXTRA” security features to some of the Mi devices. So when you get one of these Mi devices with extra security features, you need to manually activate the “Sim activation” part. But if the process goes wrong, the device will show an error sim card activation message!

The first and the second issues can be easily solved by you or by contacting the respective sim company. So you need to either solve these on your own or get a new sim card. Now coming to the third problem, how would you solve this? Well, we’ll help you with this troubleshooting guide!
