Your money is safe because your Mo-opcash PIN protects your MCo-opcash account. You are advised to block and replace your SIM card with your mobile phone service provider. With the new SIM card in place, and as long as you have maintained the same mobile number, you can continue to use your MCo-opcash through *667#. To access through the app on your new phone, you will need to visit the nearest branch in order to re-set your new phone. This is a security measure the bank has put in place to protect you from fraud.
