In the US, they have a M and T rating for cell phones. M for Microphone and T for telecoil and the higher the number, the more compatible with hearing aids/cochlear implants.
Unfortunately, Australia does not have this rating and our major Telecommunications company has fobbed me off TWICE (once online, once in a shop) as they can't help and don't offer to do any research in it.
Yesterday in the shop, I explained the Iphone (as an example) had terrible sound and I just a blank look with "but that volume is quite loud". Well yes, it might be, but it's not compatable enough with telecoils.
On the US Nokia site I actually found a list of Nokia phones with this high M/T rating, but which Australia doesn't sell.
So I email Nokia, explaining this rating and these phones and do we have anything similar in Australia.
I get an answer that Nokia does not keep records of these ratings and refer to the Nokia pages to search for a phone that suits your needs and preferences.
DUH, this is why I EMAILED YOU.
Obviously in Australia there is a HUGE gap where there is no information available on compatible mobile phones!!!
