Playing account on two phones

Hey, I recently bought a new phone and now I am using the new one to go out to school and work, and the old one at home. I did read a recent message in the game where they explained how kabam wasn't going to tolerate account sharing and stuff, and was going to ban accounts for doing so.
So, I wanna how I can do to play my accounts on my 2 phones without the risk of getting banned? Cause I don't share my account without anyone, I'm the only one who has access to it, but I would need to log in my account on my 2 phones during school or work, and log in the old one at home. So I'm not sharing my account, I'm just using it on my two phones.

So how can I do it safely without getting banned for kabam thinking I'm sharing it?


Also, I do have a mini account which a friend of mine gave to me cause he quit. So I'm just playing just in case he comes back, which I would also need to switch accounted on both phones. Although, I know that could be a bit more risky cause he could enter the game at any moment. So about that I'll just not use that account.


But for my main account yes, I do need to log in on both phones cause of questing, aq and aw,, the normal stuff.

How can I do it without the risk of getting banned?
