It depends on the cell signal booster model you need. Is it for a vehicle, or for an indoor space like your home or office? If for a vehicle, does the signal need to be boosted for the driver only, or for passengers also?
For example, a driver-only vehicle booster like the weBoost Drive 3G-S can be purchased for well under $100. The Drive 4G-X that provides 4G LTE coverage for multiple simultaneous users plus max uplink/downlink power for reliable connections at long distances from the nearest cell tower will likely cost over $400.
If for an indoor space, how many square feet of signal coverage do you need?
These and perhaps other questions need to be answered before anyone can estimate how much a booster that fits your situation might cost.
If you are not sure which booster model will provide the signal coverage you need, please contact weBoost Customer Service. Our trained service reps will ask you a few questions and based on your answers, make a recommendation. This service is free.
