We supply the SIM card as standard. You will need a router to put the SIM card in. You can purchase a wireless router from us if required. Contact us if you wish us to provide a special router that can support your main broadband service. If you do not have a strong signal indoors, we recommend that you purchase an outdoor aerial or our directional Aerial with outdoor 4G router if you are at the edge of the coverage and need a stronger aerial. If you opt for the directional aerial with outdoor 4G router you would not require the 4G router, but your would need the wireless router if you do not have one and want a wireless signal indoors. Contact us for advice.
