Does anyone know how to withold your number when making a call from a mobile?

I need to call double glazing company but have not given them my mobile no and don't want to give it to them, landline is on the blink.

I think you put 141 before the number.

Just tried it on my mobile to my landline and it worked.

you can use 141 on mine. i am on o2 don't know if that makes a difrence or not. thre is another way to block your number but i can't find it on my phone- sorry

If u go into phone settings you can set your phone to not show your caller ID

thanks I'll try it I could always block it in the settings with my other phone but can't work out how to do it on this new one.

141 works on mine - it's T-Mobile.
