I am Facing this   

SIM card prepared Problem with my Default Frimware

And 

Firmware Version: 1.1.0 0.9.1 v0001.0 Build 200417 Rel.75138n Beta Frimware

Why This Much of Troubles Occurring In the Products..

Pls Release the Official Frimware to Select LTE Band's Manually,

And Pls Solve Vodafone Simcard Not Detecting MR600 Device,

I am Very Much Disappointed with the Device,

When I get Worst thing, there is Signal Strength for BSNL 3G,

Indoor No Signal,

While Going Outside Home 50% Signal, Just one  Brick Wall Blocks That 50% Signal also, Penetrate Power for Included Rubber Ducky Antenna is Worst,

Even my Smartphone Catching Best Signal inside Home..
