Where can I signup for a monero debit card without a phone?
There are a number of "cryptocurrency debit card" providers -- services that issue you a traditional visa/mastercard/etc debit card that allows you to pay for purchases in fiat, but where the balance of the card is automatically converted from your cryptocurrency balance stored on their custodial wallet.
Note that a "cryptocurrency debit card" is distinct from gift cards in that the balance lives in an account below the debit card, not on the card itself. This is important because otherwise you may end-up with tons of different cards with low balances. It's important for my business that I can pay invoices with a single card, and if that card expires then the balance can simply be spent on the card's replacement.
Unfortunately, I've been unable to find any providers that do not require a phone to be linked to the account.
For security reasons, I do not mix insecure devices like my phone with high-risk accounts like financial services. Therefore, it's important that I find financial services that don't require a phone number to be linked to the account (shudder at the thought of implementing 2FA over SMS) or an app.
Coinsbank requires a phone number. Wirex requires a phone number. Cryptopay requires an app (which grants access to the account to a phone). Unbanked (Ternio) is dead.
Where can I get a "monero debit card" without a phone?
It's unlikely a company could legally offer such a thing if they wanted to.
Any bridge between the fiat banking system and crypto has large AML and KYC requirements.
If your only worry is device security, link a phone number and then remove that phone sim card keeping it in a secure location.
Thank you for your input, but I think it's worth mentioning that that's absolutely not true.
To be clear: I'm not asking for a no-KYC solution. I'm happy to auth with my company's official government-issued registration records, with my personal government-issued ID, etc.
I'm not aware of any regulations that require a phone number. There are regulations (eg UK's PSD2) that effectively require 2FA -- and many banks chose to implement this requirement via phone numbers.
Hopefully one day the regulations will explicitly prohibit 2FA OTPs from being transmitted at all (ie so banks are forced to use secure 2FA methods like TOTP or U2F instead of insecure methods like SMS, email, etc). But currently I'm not aware of any KYC regulations that require a phone number from the customer.
If your worried about sim jacking use a locked down google account(i.e. must use security keys) and Google Fi / Google voice for the phone 2 factor.
