** ONLY AFRICAN LOCAL PERSONS ALLOWED. NO OTHER NATIONALITY ** I need to confirm voice routing between Pakistan and Africa. The task is genuinely simple: be in any African country, keep your local SIM active—MTN, Airtel, Orange or whichever operator you normally use—and be ready for two short calls. 1. I will dial your mobile from my Jazz network in Pakistan; you just pick up and confirm the audio is clear. 2. You then return the call to a Pakistan number I provide.
