A + at the beginning of an international telephone number is different... that's the E.123 "international prefix symbol", which is shorthand for "insert your countries international dialing code here" (e.g. 011 if you're calling out from the US). Cell phones will let you insert a + directly in the beginning of the number (by long-pressing the 0 key), which will let the phone dial the correct number if you're roaming internationally. In this case, the + is at the end of the number, which is not really a standardized thing. Landline phones won't have a + printed anywhere on them, for example. And you definitely don't want to long-press 0 to actually insert a + at the end of the number, because that's invalid.
