WHich sim? Slot1 or Slot2? I tried both (i only got 1 SIM), but only data and voice works. SMS doesn't. I tried the *#*#4636#*#* and my SMSC number is wiped but I can't set it. I keep getting update error.
I can't access the Multi SIM settings > SMS settings since I only have 1 SIM. It might be a bug if you only have 1 SIM installed?
Not a bug. That setting only allows you to choose the default sim for SMS. So it's only active when both Sims are present.
