PrefixCall

PrefixCall is a Chrome extension designed to help you add specific area codes or prefixes to your phone calls with just a few clicks. Perfect for business SIMs requiring prefixes like 4146, the extension stores your chosen prefix and allows easy dialing without manual number edits. While Google's new privacy restrictions prevent automatic call interception, PrefixCall simplifies the process by letting you select the prefix in-app before initiating the call. Key features include support for prefixes such as 4146 (business calls), #31# (anonymous calls), 4088 (chargeable calls), and 456 (operator info calls). This tool helps avoid the hassle of changing contacts and ensures compatibility with apps relying on correct phone numbers.
