for those who dont know...if you use a prepaid sim card for your netbook/laptop like i do...you will need to reload airtime and make at least 1 call within 3 months...if you dont they will disconnect the sim card...and then you have to contact them to re activate the card them go to mtn and re rica the sim card with all the details etc etc.

i couldnt understand why i couldnt recharge the sim card and this was the reason...i had not reloaded airtime or made a call...so now every month i have to take the sim card out the netbook reload airtime...make a call...even if it is only 1 second...then reload a data bundle and reinsert the sim...the only way to over ocme this problem is to sign a contract
