Default Using Motorola XT 926 Verizon on LTE 4G network

Hello i have a Motorla Razr XT926 Verizon ( this was designed to also be used on the LTE network 4G on Verizon
Im in the Uk and have a 4G LTE simcard the network is EE Orange and T-Mobile
It automatically goes on 2g & 3G H+

however does not allow the 4G gsm simcard to provide a the 4G network. I want to confirm that its not my provider as If I put this in another 4G handset the LTE nework is 4 to 5 bar signal strength


I have been in network work settings selected global & also GSM/UMTS and done a manual network search no 4G is to be found

I have contacted Motorola who advise that possibly it does not work on GSM simcards only on CDMS

Is there anyway of providing a solution to allow the LTE 4G to be used I presume something to do with the hardware ?

Please expalin in simple form

Many thanks
Neil
