I purchased my phone from other then T-Mobile and found that the T-Mobile Visual Voicemail would not work.
I opened a ticket with T-Mobile only to find that this phone was not compatible with their software and since I did not buy it from T-Mobile they would not support it.
Now I have been with T-Mobile for 12 years and just in the last three years their service department has gone so far downhill that it is now worse than AT&T who held last place for decades.
Now this brings up a new question as buying unlocked phone is not a guaranty that the phone is compatible.
This will kill the free market yet again, what can a buyer do to make sure the new devices are compatible without having to pay the providers inflated prices?
