Vodafone is one of the leading telecommunications companies offering mobile services. It is available in 21 countries, including the United States. Customers who make the switch to Vodafone are often able to transfer their existing mobile phone numbers from previous providers to Vodafone. Keeping you old phone number is often more convenient than switching to a new number.
