This study has examined the commercial telecomm services sub-sector as a tool for poverty alleviation at grassroots level. It was conducted on 100 respondents (call centres) randomly selected from Ikosi-Ketu Local Government Area of Lagos State. This paper evaluates, in empirical and quantitative terms, the role commercial telecom services sub-sector has played in depleting the many facets of poverty and its grim hold on the Nigerian populace, especially at the grassroots level. Thus, the paper discusses the impact of the sub-sector on some veritable indicators of poverty reduction such as income stream, living standard, financial independence, decent accommodation, savings stream, and tendency for business diversification at the grassroots level. Data for statistical analysis were elicited via structured questionnaire. The data were analyzed using descriptive and inferential statistics (parametric statistic – Chi-Square). The results showed that commercial telecom services sub-sector has had significantly positive effect on the veritable indicators. Therefore the paper recommends, among others, that commercial telecom services should be an integral part of any policy or programme aimed at alleviating poverty at the grassroots level.
