to fix 3g problem in V6 beta do the following:
Dial *#*#4636#*#*
Phone 2 Information -> Select GSM only
Phone 1 information -> Select WCDMA Preferred
Now you can select 3g or 2g at the sim settings
:)
It seems that I cannot select 3G network under prefered network in my Redmi 1S. Even if I selected it switches back to 2G only
Does anyone has the same problem?
Use Go SMS PRO or Handcent to send your SMS message, but you may only use the 1st SIM card, not the 2nd SIM. You have to set the proper settings in Go SMS PRO or Handcent to select you regional/country settings
