Mexico is no longer covered by your units, and is not reachable for now
Mexico was billed at zero even though it is an international destination, exactly like the United States. It now goes through international. In practice, while calling and texting abroad are not available, calls and texts to Mexico no longer go out. When international opens, they will be charged at Mexico's rate and taken from your International Balance. Your units cover Canada. Our pages also said the plan covered the United States. That was wrong, and it is fixed.
