Getting Internet+TV done being abroad

Hi

I am right now outside of Belgium but going to move very soon

I do not want to lose time and want to get internet and mobile immediately , I am trying to get in touch with sales team of Orange to get this done without any success , it seems this is only possible if you already have Belgium phone number

is there is a phone number that I can call , I tried +32 2 745 95 00 but they were completely useless and have no information , they given me 0800 number which ofcourse you can not reach outside of Belgium

appreciate the help

Regards
