Simcard just cut-off

<p>I was away for the weekend in the Drakensberg with limited cellphone access. I usually get my new settings on the 1st of the month with my normal top up amount and data. This month I was just cut from the network. Meaning, they billed me, and I have data ect to use but I have been completely unable to log on to the network since. I have tried phoning to sort this out. They tell me that the simcard needs to be swapped. With no warning or reason it has expired. Now I must go and fork out my money to reconnect to something that worked just fine last week.</p>
