Hi there! You need to go to an MTN store or Rica the prepaid SIM you bought from PNP. You will need your green ID book or ID card (Driver’s license wont work unfortunately) and a proof of residence. This will activate your SIM on the MTN network. Once the SIM is active you can sign up for your Mobile Voice or Data account on the Afrihost website. Alternately you can order from the Afrihost website and they will deliver you a new SIM and they will RICA you when they deliver it. If you need more details regarding RICA if you order via Afrihost then you can see that here: https://www.afrihost.com/site/page/rica_information . Hope this helps!
