An e-portal system that allows mobile phone users to recharge their phones online without necessary purchasing any recharge card is proposed. With this e-portal system, users simply provide the amount to be loaded on the specified phone number and some series of validation are performed before finally recharging the phone with the specified amount. This e-portal system also eliminates the burden of generating random numbers as recharge cards and the subsequent huge database accompanied with the storage of these randomly generated numbers. Mobile service providers are still faced with the challenges of inefficient bandwidth utilization and congestion in the transmission channel.
