Documented matches
Three kinds of buyer, each written as a short list of requirements. Every vendor is checked one plan at a time, using only what it publishes for that plan, and is named with the plan that decides and that plan's price. A requirement met on one plan and another met on a different plan do not make a match. Nothing is scored and nothing is ranked: vendors are in alphabetical order, and we have not tested any product.

Each mark opens the vendor's exact words and the date we read them (pages read 14 Nov 2026). A vendor's lead plan is the one its row shows in the comparison. Each vendor starts on its cheapest plan you can buy without a sales call that can bill past its included minutes, on the vendor's own pages; a pay-as-you-go plan counts. "Could not be confirmed" means the vendor's pricing, documentation and terms pages did not say for that plan, or two of its pages disagree; it does not mean the vendor lacks it. A match here is a match on paper. It says nothing about voice quality, reliability or support, which we have not tested. To set your own requirements, use the comparison.
