Tried coinomi before on claiming dogecoin from a physical coin loaded with doge. I’m not sure if this is same with paper wallet but I do import my keys there and successfully retrieve my dogecoins without paying fees.
I remember this wallet is being use to redeem other physical coins such as Bitcoin and other paper wallet too.
Last time I remember, I think coinomi has some unresolved technical issues such as failure to synch properly with the blockchain and another worry is that it's a close sourced wallet that members should avoid as much as possible
