No way, that stays at home. If you need funds while traveling, hot wallet, ledger, or cex.

No but if you needed to you can port your seed to a ledger and use that to sign trnx

I'd love a portable version of GridPlus to use as a @safe 1 of n approval account. From what I've heard the team and product is great.

You'd have to resync your Lattice with every new network you join, so unless connecting to your phone's personal hotspot using the same SIM, it would be impracticable.
