The issue can arise for bugs in installed firmware, or incorrect phone number identification, or device failures running under custom ROMs. In any case a user gets either “Your SIM card is not activated” or “SIM card activation error” message.

Method 1. Activate SIM card on Xiaomi official site
It is an easy and effective method if the cause of this issue is an error has made in registering a Mi Account. To employ this method one has to enter Xiaomi official site https://account.xiaomi.com and enter his/her Mi Account login and password.

This message will contain a code which is to enter into the website. Sometimes these actions are enough to activate SIM card.

Method 2. Enter the number manually
This method can work if the cause of the issue is the number identification error. When you get the SIM activation error message, tap on it. You will see a failure SMS message. Then you should keep tapping a repeat button for 3-4 times until phone number input window opens. Enter your phone number in. Hopefully the issue of the SIM activation will be fixed.

Method 3. Activation via mobile operator
Usually a SIM card is activated by sending a system message to another country. This kind of messages are often blocked by cellular network providers. Thus before trying to fix the issue employing this method one better call provider’s tech support service to find out whether this service is available on his/her phone. One more point. One has to have enough budget on his/her account (this service is not free of charge).

  5. I think this problem is country related.
    nothing worked for me from my phone.

    The only workaround I've found was to enter i.mi.com website from my laptop, logging in from there and activating cloud, sim card, and all the necessary settings from there.

    Hope it'll work for you guys too.

    cheers

  6. The solution is simple. For this, no languages ​​or other manipulations are necessary. According to his recommendation: Settings – Sim cards and mobile networks – Internet in roaming – set to "Always" (do not worry, this is necessary for several minutes) – then you need to start the SIM Activation request again (I just rebooted the smartphone and into the status This request appeared again at the bar) – I clicked there – SMS sending apparently went (of course, the balance should be replenished) – and a message about successful activation was instantly displayed. After that, the Internet in roaming – put "Never", that's it 🙂 the SIM card item finally sees the phone number! It was precisely the solution to the situation that was sought – and this is definitely a fresh working method, probably the matter is in the sim and operator, the "roaming" option helps, and in none of the articles and videos on youtube this method was used. (Use google translate! Sorry if there are errors )
