qw, the use of the term 'unlimited internet' is not a con. It is a marketing gimmick. They are everywhere in every industry. Though I hate them, it has come to be accepted as 'normal' by marketers e.g, airlines stating fares, but in reality it is exclusive of tax which you will have to pay, restaurants the same, etc.
But I do feel they should have informed us that the offer was for only 10mb. When I subscribed I browsed and at the end I was shocked to check my credit and found it to be -0.08(by the way, how do you end up with negative credit? It has happened to me severally)
But Safaricom speeds are way faster than its rivals and this offer is a killer blow to them.
GOD BLESS YOUR LIFE
