Nope, they aren't the most trusted wallet at all, I saw many complaints against them and many crypto enthusiasts lost their crypto assets upon storing this close source wallet. I think there is a failure of their system or lack of customer support.
In addition to TravelMug links of scam alert of this forum.
In short, they are vulnerable to a scam. Buy a hardware wallet if you really want safe storing of Bitcoin OR much prefer to use the Electrum wallet. Less scam complaint.

As we said above, Coinomi is trusted by millions of users, so unfortunately occasionally you will find some having connection issues or who mishandled their seed. Regardless of the issue, we try to help the best we can and will always respond quickly on our official support page.
