I moved to T-mobile 1 month ago for an 18 month 100% cashback deal.
Little did I realise until it was too late that T-mobile charge for voicemail calls. These calls are not included in your minutes, they cost 12p per min or 12p per call if you call is less than a minute.
So far I have spent an extra £6 per on these calls (but had I actually listend to all of my voicemails in full I think the figure would be closer to £20!). By the time my 18 months are up I fully expect to have spent over £100 on voicemails (possibly over £200 if I start listening to all my messages). Had I known they charged for voicemail I would not have switched to T-mobile.
For Anyone else thinking of getting T-mobile I urge you not to do it if you check or recieve voicemail regulary. I usually get 3 voicemails per day as I cannot use my phone at certain times of the day, but if you only get 2 voicemails per day (all of which are under 1 minute - mine usually average 5-6mins) it will add £7.20 per month!
I am gutted about this, but I dont see that there is anything I can do as Im sure it is in the small print. From now on all T-mobile deals are cold for me. I am very bitter and hope whoever thought up this con gets made redundant pretty soon in all the job losses that are just around the corner when Orange eats up T-mobile.
