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

    The only workaround I've found was to enter 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.


  7. 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 )
