Orange Luxembourg notified us of a wave of fraudulent "Wangiri"-type phone calls sweeping through the Grand Duchy.

Luxembourgish people have been targeted by the "Waringi" phone scam. This is a scam wherein an unknown number will call your phone, let it ring a couple of times and leave you with a missed call.

The idea is that you will call back to find out who the call was from. Do not call back - this may leave you with a hefty charge added to your monthly phone bill.

The scam has been relatively successful in Luxembourg because the numbers in question use a dialing code similar to the Luxembourgish one (such as 352, 33 or 338).  The numbers can often be retraced to the island nation of Tonga.

In short: do not call back unusual numbers.

Orange Luxembourg assures its customers that they will not be charged for these phone calls. The company is also working on blocking suspicious numbers.
