I just found a neat little trick to bring down the cost of your mobile phone bill. If you have to pay for picking up voicemail, try calling your mobile phone number instead. You get to pick up your messages in the normal way but it bypasses the standard voicemail function and just falls within the usual free minutes allowed on your tariff. So, if you’re like me, and don’t use all your minutes anyway, there’s no additional charge. Could be it only applies to my provider (T-mobile) but it's worth a try!
