First of all, check online dashboard (https://lk.megafon.ru/) to disable all foisted promotions.

Then add "Stop-Content" service to disable some dangerous "subscriptions".

Then check your exact modem name and series (M150-4 or something else). Most of MegaFon modems can be easily unlocked. If you unlock it, it will accept any SIM.
