FAQ
Mobile Signal Booster Kits — FAQs
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.
Will a Siglift booster work with Jio, Airtel, Vi and BSNL?
Yes. Siglift boosters are matched to the frequency bands used by Indian operators, so they work with Jio, Airtel, Vi and BSNL. Because each operator uses different bands in different circles, our team confirms the right model for your SIM and location before you buy — just share a screenshot of your phone's network info on WhatsApp.
How much area can one booster cover?
Coverage depends on the model and on the outdoor signal strength. Siglift home models cover roughly 1,500–3,000 sq.ft, while high-gain models cover 5,000 sq.ft and the SL-850-27DB up to 10,000 sq.ft. Larger or multi-floor buildings add extra indoor antennas with splitters. Tell us your floor area and we will recommend the right kit.
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.
