Social tariffs have provided relief for some at a time of household income squeeze and otherwise unavoidable high inflation-driven telco price increases.
Adoption has risen but remains very low, limiting their effectiveness, and more widespread adoption would expose their shortcomings, with the risk of penalizing low cost operators and significantly increasing prices for non-adopters (by up to 20%).
A better approach might be to recognize that affordability issues are narrower but deeper than current social tariffs can address, with fuller, centrally funded subsidies targeted more narrowly at those most in need.
