If you are out there asking yourself, can I swap turbonet sim cards on the MTN Turbonet router, then you have to visit any MTN customer care office, present to them your ID card, the previous number you are using on your Turbonet router and the new number you want to change to. But swapping SIM Cards in your Turbonet device like removing and putting different SIM card is not allowed and can get your SIM card blocked for 6 months. This can get your Turbonet device locked, unless you visit any MTN office located in your area to unlock your Turbonet router for you.
