is moshimoshi used on the phone only?
Usuallly. Check out this article:

Saying yes to it only being used on the phone seems inaccurate based on that article. That article says itâs also used to get somebodyâs attention even when youâre not on the phone.
Youâre not going to use moshi moshi off the phone too much. But when you do itâll usually be to get someoneâs attention. If your friend is spacing out, you can wave your hand in front of their face and say, âmoshi moshi.â
Or, if you see someone passed out on the sidewalk, you can tap their shoulder and say, âmoshi moshi!â
Huh, guess I didnât read the whole thing carefully enough.
