Hi, where we can see or find the telecom vas domain jobs like SMSC, MMSC, SDP, CRBT in UAE and in other middle east countries ?

I hear you for it's hard to find specialized telecom career forums specially for non operators jobs, I think the best is to look for specialized recruitment agencies that focus on telecom. Another way is to search for products such as VAS products, check who is selling them and check their career pages
