Query related to WWAN on android device(Zebra TC75x model)

[nallamahesh1]

I have android devices that have issues with Cellular signal bars not showing up.

SIM cards activated, OTA verfication done.

I think its something related to WWAN enable. Does any one know how to enable WWAN directly on a android device ?

Can any one throw some light on *#*#4636#*#* Phone information details or any related links

*#*#4636#*#* will let you choose the network type, but unless you've tried to put it on a CDMA network (Verizon, Sprint) - it's GSM-only, it works with all GSM networks, so you don't have to fool with that. (If it's Verizon or Sprint, change carriers - it can't be made to work with CDMA networks.)
