Just remember when selecting Prepaid that you are dealing with the Billing System directly. It is programmed to turn off services when there is not enough funds (ie. To collect monthly fees). If you the kind of business person who pays attention to their emails then this is perfect, however if you only like to check in once a month, prepaid might not suit your needs.
Simple Telecom also supports direct deposit payments, please use the bank details and reference number on your payments so we can match the payment to your account correctly.
Additionally, You can view you invoice history and download a PDF of past invoices.
Pre-paid accounts can view their past payments and the invoices that are generated for those payments.
