Nope, that is not true.

Voipcheap's automatic dialling prefixes depend on what country you filled
out when signing up. They do not change when you take your SPA-box (and
VoipCheap-account) with you to Aruba, in this case you still dial 10-digits
to dial a number in the Netherlands, so without the 0031.
