Questions about Karos
Yes. Pick a US number, enter it on Karos, and the verification code arrives here in seconds — usually under 30. If a code never comes, you're not charged.
Our numbers are real US mobile lines with physical SIM cards, not VoIP. That's exactly the kind Karos and other strict platforms expect, so they're accepted like any regular phone.
A single Karos verification starts from $0.48 per code. You only pay when a code is delivered — failed attempts are free.
A verification number is for one code. If you need the same line for repeat logins or ongoing Karos codes, choose a rental instead and keep it for the full rental period.
Your real number never touches Karos. You get the code and move on — no personal details handed over, and no spam calls or texts afterward.
It almost always does within a minute. If it doesn't, the number is released and you keep your balance — nothing is charged for a code you didn't receive.
