Hello,

I'm looking to inquire some help on enabling otherwise blocked bands on these devices. I live in the U.S. and could greatly benefit from it. I looked at some posts on using the QPST and QXDM tools for Qualcomm devices, however I am a bit out of my depths as far as this goes. I know that 888 has a built-in modem (x60) but I couldn't find any material on all the bands it supports. If anyone of you could help point me in the right direction, it would be very much appreciated. Thanks :)

    They're was some ussd codes posted in this forum recently that supposedly unlock carrier aggregation in the China model, maybe some one can remember where and link you to them.....

    I get :

    No VOLTE , maybe it isn't in this country
    *#*#86583#*#* (VoLTE)
    *#*#869434#*#* (VoWIFI)

    These worked for me. It will say turned carrier check off then you can find the option to turn VoLTE/VoWIFI on under the sim section (for each sim installed).

    However, I'm trying to enable blocked bands on the snapdragon's modem. Some of them they don't enable on different phones because of legalities and some just aren't supported by the chip.
