Online transaction is a boon for the operators, as there is less commission if it is done via their own recharge portal. It is quite interesting that all most all CDMA service providers (Tata, Reliance and MTS) are offering extra data to their high speed data users if they recharge online.
Tata Teleservices offers 15% extra data on all recharges more than Rs 500 done on their web portal to Photon Plus users.
Reliance Communications, which offers HSD services under Netconnect Broadband+ brand also offers similar benefits. And recently the offer is extended to Reliance 3G (GSM) data plans too.
Though RCom offers 10% extra data, it is available on all packs including STV97 (offers 300MB for 30 days, with web recharge you will get 30 MB extra). RCom users while top uping their prepaid account will also rewarded with extra talktime when they use instant recharge.
Sistema Shyam Teleservices (SSTL), which operates under MTS India brand also offers some special plans for its high speed MBlaze users. These plans are valid on web recharges only done over MTS Online recharge portal.
