Cel-Fi reviews


Nextivity's second generation 3G repeater is an intelligent indoor coverage solution for 3G/HSPA+, designed to boost your mobile signal from outside and disburse within your home or office.

NOTE: This product will only operate on the Optus 3G 900/2100 network. It will not support the GSM or 4G band.

Cel-Fi differs greatly from the standard indoor repeater due to its ability to not interfere with the mobile network or other users. Often referred to as a Smart Repeater, the Cel-Fi has the ability to provide maximum coverage, be network friendly and can be easily installed by the end user.

The Cel-Fi for Optus is locked to the Optus 3G Network and is also location locked. Once you turn on Cel-Fi it will lock to the towers in your area within 32 hours and will stay locked to those towers. If you change address please contact our support department on (07) 5577 0500.
