"Under the 10-year agreement, I.B.M. will handle customer service for Bharti and provide the hardware, software and services to run everything from billing and call-traffic management to delivering new services like music and video. The deal takes the broad partnership between Bharti and I.B.M., begun in 2004, beyond India. I.B.M. is not disclosing the dollar size of the deal, but analysts estimate it at more than $1.5 billion over the decade-long span. The Bharti contract also punctuates I.B.M.’s Africa strategy. The company’s presence in Africa dates back 50 years, but in the last five years I.B.M. has invested $300 million in the region."
