I've sent to 8310 the example mentioned in the FAQ nokie forum.
In 3310 it shows perfectly - SMS TEST - screen saver + ringtone,
but in 8310 it shows: "Message cannot be displaeyd here"
Doesn't 8310 support this feature?
8310 does not support downloadable profiles. Phones supporting this feature are: 3310, 3330, 3590 and 5510.
Updated list of supported Smart messaging features will be available shortly at FAQ section.
