Only Yota (for modem) offers really unlimited data. There are 2 completely different Yotas - Yota for smartphone (only SIM card, NO unlimited data, strict FUP, mobile number in +7 999, +7 991 area codes assigned) and Yota for Modem (modem or router, no calling, really unlimited data with some mild restrictions like P2P and torrents slowed down, without calling ability, without mobile number, only account ID).

If you unlock the modem (it is possible), it will be able to use any normal 3G/4G SIM card. You can try Yota for Smartphones, MTS, Tele2, or any other operator you want.

I can't promise it will work with Yota for Modems USIM card. They will urge you to buy their own modem with internal USIM carf built-in.

Now about MegaFon. I need to know what kind of promotions and subscriptions they add you. There is no one way to disable them all and prevent.

There are several ways to make your life safe, including very strange ones. Unfortunately without looking through the stats and dashboard ticks for your number I can do nothing for you.

Generally speaking, there are 3 possible types of catches: "services", "subscriptions" and "SIM menu offers". There are very cool and unusual way to stop it. But not very easy for you.

And more, this is abnormal situation, not usual.
