Barclays has a USSD mobile banking service called "Hello Money". Try it *224#
Works OK for bill payments, Transfer to MPesa, Transfer to other bank accounts etc.
I find it easy to use and I actually never visit the banking hall or their ATM.
They also have "Retail Internet Banking" for retail clients and "Barclays Integrator" for corporate clients which can accomplish virtually all banking instructions.
I don't work with Barclays"..I am because we are. "― Ubuntu, Umtu,
