FAQ about Triangle
Is the service available at my address?
Contact the provider with your building and neighborhood. A nationwide licence or a published package does not confirm installation at every address.
Do the listed prices include VAT and equipment?
Tax is labelled for each package when the official source states it. Equipment and setup charges remain unknown unless explicitly listed in the package conditions.
Are these tested download and upload speeds?
No. These are advertised provider figures. Measured performance depends on the network, device, Wi-Fi conditions and test endpoint.
Sources and methodology
Historical registry does not establish current licence or address-level coverage.
Research starts from the supplied historical nationwide licence list and follows official public websites. Inclusion does not certify current licensing, independent service quality or address-level availability. Source check dates and tariff effective dates are different.
