EE don't advertise this at all but you can listen to your voicemail for free on pay as you go dialing 1210 rather then calling 07953222222 you will have to top up to call your voicemail number for that.
I don't know about other networks but I think you can dial 1210 on other networks to see if it connects to voicemail for free.
Nonsense...
Calls are only free if you have inclusive minutes in a bundle other then that your looking at 30p a minute
http://ee.co.uk/help/my-account/pay-as-you-go/view-standard-ratesIf you have an EE Phone you only need to dial 1 to access voicemail.
0795322222 is the number you call from a Non EE Phone.
You only Call '1210' from your phone (free call) to stop calls being diverted to Voicemail when your phone isn't answered, is unreachable or engaged..
