8ta LTE router availability

I use 8ta for internet.

I use a Huawei B683.

I would like to buy a new router with is LTE capable in the 2300 Mhz band so I can enjoy the benefits of the LTE coverage I have. I have been to 2 8ta/Telkom stores and they seem to have no idea what device I might be able to purchase which will fill this need.

Is there anything available on the market which is compatible with 8ta's network?
