    go here, user said it worked for his Thunderbolt & i can confirm the Dialer code does open the hidden menu on my Thunderbolt

    you're basically going into the phone & telling it to manually switch over to something like CDMA only, or EvDo only

    scroll down, see the SetPreferred Network Type--from which you can choose what Network type the phone will then use

    Network Type options:
    CDMA auto (PRL)
    CDMA only
    EvDo only
    CDMA + LTE /EvDo auto
    LTE MODE

    these options are shown--and any one of them can be chosen.

    to clarify/summarize: Go into testing mode by dialing *#*#4636#*#* > phone information > Scroll down and Select preferred network type to be "CDMA auto (PRL)" rather than the default "CDMA + LTE/EvDo auto" (thanks PandaPaul)


    not responsible if this hurts your phone---putting it out there that there is in fact a way to switch radios


    Edit: note, it also says
    "GSM SERVICE: in service"----kind of interesting
