The document discusses an international business expansion into the Brazilian mobile phone market. Brazil has a large, growing mobile market that is dominated by prepaid phones. The expansion strategy is to partner with Telecom and acquire their stake in VIVO, gaining a 31% market share. This would allow aggressively advertising their 3G broadband network to capitalize on Brazil's growing economy and increasing demand for high-end smartphones and internet access. The factors for consideration include the acquisition costs, substantial initial investment required, extensive growth opportunities in Brazil's expanding economy and telecom sector, and VIVO's low price due to debt levels.
