SL-8518-23S — frequently asked questions

Which networks does the SL-8518-23S work with?

The SL-8518-23S amplifies 850 / 1800 / 2300 MHz (Band 5 / Band 3 / Band 40). With typical Indian band allocations that covers:

Jio: all of its usual bands — 850 MHz (Band 5), 1800 MHz (Band 3), 2300 MHz (Band 40)
Airtel: 1800 MHz (Band 3), 2300 MHz (Band 40)
Vi: 1800 MHz (Band 3)
BSNL: none of its usual bands — choose another model

Bands in use vary by telecom circle and building, so send a screenshot of your phone’s network info on WhatsApp and we’ll confirm the SL-8518-23S suits your SIM before dispatch.

How much area does the SL-8518-23S cover?

Up to 5,000 sq.ft indoors when the signal outside is usable (at least one or two bars on the roof or terrace); thick walls, basements and a weak outdoor signal reduce it. Extra indoor antennas with a splitter extend coverage to more rooms.

What is a mobile signal booster and how does it work?

A mobile signal booster (also called a mobile network booster or repeater) has three parts: an outdoor antenna that captures the existing signal from the nearest tower, an amplifier that strengthens it, and an indoor antenna that rebroadcasts the stronger signal inside. It improves calls and 2G/3G/4G data wherever at least some usable signal is available outside the building.

Do you provide installation in your home or office?

Every kit is designed for easy do-it-yourself installation, and our technical team guides you by phone or WhatsApp. Professional installation is available in many cities — call or WhatsApp us to check availability for your location.

Will it work if there is no signal at all outside?

A booster amplifies existing signal; it cannot create signal from nothing. If you get at least one or two bars on the roof or terrace, a booster can bring strong indoor coverage. Our experts can check your location’s signal before you order.

What warranty and support do I get?

Siglift boosters come with a 1-year warranty, free shipping across India, cash on delivery, a 10-day return policy and 24x7 technical support.
