Using 411 is a convenient way to get phone numbers that are not in your mobile address book, but it can also be expensive. The fee is $1.99 plus airtime for up to three numbers per 411 call. That can add up to big fees on your mobile bill if you use it much. A great alternative is to use a free Google feature. If you text 46645 with the name and city you are seeking in the message area, Google will send a return text containing the information – typically phone number and address. If you have unlimited texting, it is free. Otherwise, you pay only the cost of the texts.
