Good to know
What your Luxembourg number does brilliantly — and the few things no second number can do.
Most Luxembourg apps and websites accept HeyNum numbers. Banking apps and LuxTrust verification rely on your identity and bank, not just a phone number.
Your number includes calls and texts to Luxembourg numbers. Calls and texts abroad use pay-as-you-go credit, with rates shown before you dial.
See calling ratesYour number stays yours while your subscription is active. Cancel in one click and it remains live until the end of the period you've paid for.
Like most internet phone services, HeyNum can't call emergency numbers. Keep a regular mobile line for emergencies.
