At first we need make clear what the eSIM it is. Embedded SIM (eSIM) is just a physical SIM gone digital. Like a physical SIM card, an eSIM provides your connection to the T-Mobile network. An eSIM is built into your device just activate it with your account information rather than inserting a physical SIM.

Is there an industrial router built-in eSIM? The answer it is “yes”. E-Lins Communication Co., Limited owns model H685f and H900f support eSIM.
But you need inform E-Lins you require eSIM before place order. The end user can provide their ISP’s information to let E-Lins help embed into H685f and H900f’s hardware; or the buyer can express the eSIM chipset to E-Lins and require E-Lins to help embed eSIM chipset into routers.

Both H685f and H900f are excellent 5G industrial routers, as for more information, you can contact with E-Lins’ Team.
