Will a fax get through if the number is a mobile?

Summary

No, whichever operator you choose. A fax transmission requires modem-capable equipment at the receiving end — something no mobile phone has. Faxeroo therefore connects only to fixed lines, across the seven countries covered.

A dialogue played out between machines

A fax transmission opens on a burst of identification tones: each device introduces itself, the two settle on a speed, then the pages circulate — provided a machine picks up on the other end. A smartphone, for its part, presents the call to a human: the negotiation falls through.

Even the mobile network would change nothing

Mobile networks compress audio aggressively to preserve bandwidth. Voice-optimized processing destroys any modem transmission. A fax machine plugged into a cellular router would fail just the same — a matter of physics, not business policy.

Which channels to prefer?

To warn them that a fax awaits them at the office, an SMS suffices. The comparison between fax and SMS helps decide, situation by situation.

Key points

  • Receiving a fax? No smartphone is capable of it.
  • Cellular compression renders the fax signal unusable.
  • Faxeroo targets only landlines.
  • To a mobile, prefer email, messaging or a text.
