How do you get a '+' sign when dialing a phone number?

[x.alotlikevegas]

I'm currently trying to get twitter on my phone. If anyone doesn't know what twitter is, its a website that you can update what your doing and fallow other peoples updates. Anyway, I'm supposed to send a verification number by sending a text message to this number;+447624801423. But I have no idea how to get a '+' sign where I insert the number. Does anyone know how?

Hold down the "0" key

depending on the phone! sorry i can't really help. it could be a QWERTY phone or just a plain different phone. i know you can do it just try your best usuallyy there is a button that says symbols or click the pound button or the ones at the bottom near the 0

it varys on different phones. on mine, i have to hold down the * key. the best advice i could give you, is to try the bottom three keys, one at a time *, 0, and #.

Press the * key twice or put 00 instead (0044etc).
