Wish I could help ya out but I still haven’t used the 3 cold cards I have yet lol

You have the mk4 i have that in the cart right now there is a deal. Should i get the usb call the sell as well the non data cable. My question is simple. With the mk4 can i spend bitcoin from my phone like with bluewallet and mk4 as the signer. Very basic question

I honestly don’t know my man I’ve never used it…

Now im watching Natalie brunells coldcard tutorial hahahaha

I hope you get the answer you’re looking for…

I don’t think I understand the question there might be a typo in there. Happy to help but what is the “call the sell”

I’d guess "cable they sell"

Yes you can, with nunchuck wallet
