Is a particular mobile handset or service provider required to make or accept a mobile payment?
Absolutely not. Your existing mobile handset, even if it’s the most basic one can be used to make payments via PayMate/GiftMate and SBI Mobile. It does not require any SIM change, or GPRS connectivity. PayMate/GiftMate and SBI Mobile works across all operators (GSM or CDMA) so you needn’t get a new connection.
