Why is it key to manage the recharge of SIM card in a good way?

• Your Call Termination solution is sensitive to the remaining credit on the SIM card, as without credit on SIM cards, your business will simply stand still, your revenues will stop and, finally, you may lose your customers.
• As your management of recharge strongly depends on SIM card credit voucher, voucher type, voucher records or voucher assignation, then errors or “bad” voucher pin codes can lead to dramatic losses in your business.
• Buying your vouchers from resellers can be critical for the safety of your SIM cards, as Anti-fraud systems highlight resellers selling too many vouchers being found in “fraudulent” usage. The consequence is getting all your SIM cards blocked once such reseller has been flagged by the mobile operators NOC.
• Managing your vouchers physically with your Call Termination solution is also a leak of security as users may have access to pin codes and steal or misuse them.
• Poor mobile network connection can make topping up SIM cards via SMS, IVR, USSD, credit transfer (or any combination of those) unreliable. Sometimes the network is simply unavailable for hours due to a mobile operator simply changing its network rules or configurations.
