087 Numbers are not portable between network providers but when the porting to Euphoria Telecom the answer is MAYBE....
ICASA assigns batch of 087 numbers to each network provider and they are not portable. However Euphoria Telecom is connected to multiple provider's networks. So if your 087 number is on one of the networks we use for call termination we could port your number to our platform.
The only way to find out for sure is by sending a request to firstname.lastname@example.org with the 087 number in question so that we may verify and let you know.
Remember all Geographic (i.e 01, 02, 03 ,04, and 05) numbers are portable in South Africa, as long as you have all the documentation necessary that proves you own the number.
