This is a known issue, you should get a replacement under warranty. Basically the support form should work, if for some reason not, try giving them a call.
Try to take off the display and reassemble the phone. See also here:

However even though the specs say
the phone should work with some frequencies here I cannot use either the travel
sim or my sim from Europe here.

Indeed, numerous carriers should work with the FP2. You can check here which should or may not work: http://willmyphonework.net/. Did you make sure the SIM is unlocked for using it abroad? Check with your provider. Are calls working? If it’s only data that did not work, check your APN settings. Since apparently 2G does not work for most carriers, make sure that the right SIM is set to 3G/4G (only one SIM can use those, the other is then automatically set to 2G only).
