FAQ’s

Can I get SMS on my Naperville virtual phone number?

Yes, your Naperville FlyNumber can receive SMS — incoming texts are forwarded to your email for a small per-segment fee. You can also send personal, person-to-person texts to numbers outside the US — though delivery depends on the receiving carrier accepting texts from US numbers. Texting US numbers is coming soon and will run as A2P, the registered route US carriers require. Full list of SMS enabled numbers here.

Can I use my Naperville virtual number for 2FA or other verification services?

This really depends on the company/service sending the SMS to the FlyNumber; it's up to them to actually send the text. We can't guarantee 2FA or short code SMS will work. Texts from regular mobile phones should work fine though.
