Do you experience dropped calls or choppy, incoherent conversations on your GCI Wireless cell phone within your home/office or in car/truck? GCI Wireless offers very good cellphone coverage but housing materials such as concrete, metal, low emissivity or tinted glass windows, etc. block cellular signals and prevent good mobile reception indoors in homes/offices and outdoors in cars/trucks. Our signal boosters listed below and/or our cell phone booster installation service can help.
