How to enter the + (plus) symbol on your mobile phone

How do I enter the + (plus) symbol on my mobile phone?
To enter the + symbol on your mobile, either:
  • hold down the 0 key
  • press * twice quickly.
Each mobile is different, but usually one of these methods works. If it still doesn't work, please check your mobile's manual. If you don't have your manual handy, find out how to view it online.
