Dual mode = GSM and 3G.
No, dual mode = switching between umts and gsm, whichever has a stronger signal.
umts = forcing 3g regardless off it's signal strength.
switching between umts and gsm usually results in a dropped connection, which in the case of a video call would result in a dropped call.
My N73 network mode has no option for UMTS - only GSM and Dual mode - I therefore cannot make video calls unless UMTS is available - please advise
No UTMS option??
Yeah you could use dual mode then but that presents the problem of switching between the 2 modes. I though all N73's came with the 3 options.
GSM
UTMS
Dual Mode
Well that's what mine has
Is it not possible to upgrade the firmware to change this?? Even if that means changing the product code?
