I have blixit on my iphone. It works but your channels will be zombies when its not open, so i would only open 1 or 2 channels. Also, for the OP, you dont need a 1 TB card. The node will be on your phone, so its not gonna be private unless you are running like GrapheneOS. You might as well just use a public node for the btc node, and blockchain so you dont have to download the chain.
Also, blixit would connect to your personal node or a public node. It technically cant be a full node, its just running LND.

Yes, you wouldn't be able to receive a payment when it's offline/powered down.

But that's only a lightning node. I meant a full fat bitcoin node :).
