Hello how may I help you? How many numbers can I add to a single contact? You can have up to 5 numbers for each contact That SUPER is unfortunate. Are you sure? How many numbers did you want to add? 10. I'm not pleased with that number you stated. I'm very sorry. I may have a solution. You could make 2 separate contact listings with 5 numbers each. Like personA and personB so that you could have all 10 numbers recorded Sounds complicated. You mean to tell me there is no way possible to add 10 contacts underneath one identity? I'm sorry, 5 is the most we can do. I apologize for the trouble. I am really disappointed about this. Thanks anyways. Sorry I couldn't be more help.
