Questions about Glassbox

: Yes. Pick a US number, enter it on Glassbox, 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 Glassbox and other strict platforms expect, so they're accepted like any regular phone.
: A single Glassbox 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 Glassbox codes, choose a rental instead and keep it for the full rental period.
: Your real number never touches Glassbox. 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.
