That is not a U.S. number that you would dial "1+". It is an international number, specifically a mobile phone in Nigeria, country code +234. From the U.S., you would dial it as 011-234-etc.
Country code +234 is Nigeria, and a number beginning +234 70, with 8 more digits following, is a mobile. To dial that number from a GSM mobile, enter it beginning with +234 (including the plus sign), and the network will automatically insert the appropriate prefix. Otherwise, dial your international access prefix (most commonly 00, but many countries use other prefixes) and then the country code 234 and the rest of the number.
