Improves calls, SMS and 4G/LTE data on every major Indian network — for every phone brand.
2G · 3G · 4G/LTE · VoLTE calls — matched to the bands your operator uses in your area.
A mobile signal booster is a three-part system — an outdoor antenna, an amplifier and an indoor antenna — that captures the weak signal outside your building, strengthens it and rebroadcasts it indoors. The result: no more call drops, clear voice and faster 4G data wherever you had one or two bars.
An outdoor antenna on your roof or balcony picks up the existing signal from the nearest tower.
The SIGLIFT booster strengthens that signal many times over, on the bands your operator uses.
Indoor antennas carry strong signal room to room — and your calls and data back to the tower.
12 models matched to Indian network bands — from compact home kits to high-gain systems covering up to 10,000 sq.ft.

SIGLIFT boosters amplify the frequency bands Indian operators use for calls and mobile data: 850, 900, 1800, 2100 and 2300 MHz, depending on the model. That covers 2G, 3G and 4G/LTE, including VoLTE calls on Jio, Airtel, Vi and BSNL.
5G phones benefit too. They usually place calls over 4G/LTE and fall back to it whenever 5G is weak indoors, so a strong LTE signal means clear calls and stable data on any phone.
Headquartered in New Delhi, SIGLIFT supplies and supports mobile signal boosters across India — for high-rise flats and basements in metros, offices in business districts, and homes in hilly or rural areas far from the nearest tower.

A mobile signal booster (also called a mobile network booster, cell phone signal repeater or network amplifier) is a device that captures weak mobile signal outside your building with an outdoor antenna, amplifies it, and rebroadcasts it indoors through an indoor antenna. It fixes call drops, cracking voice and slow 4G data in homes, offices, basements and commercial buildings.
It depends on the frequency band your operator uses in your area. Jio mainly uses 850 MHz (Band 5), 1800 MHz (Band 3) and 2300 MHz (Band 40); Airtel, Vi and BSNL mainly use 900 MHz (Band 8), 1800 MHz (Band 3) and 2100 MHz (Band 1). SIGLIFT offers models for each combination — send us a screenshot of your phone's network info on WhatsApp and we will confirm the right model for free.
On Android, install a free app such as “Network Cell Info” or open Settings › About phone › SIM status to see the band/frequency. On iPhone, dial *3001#12345#* to open Field Test mode. Or simply WhatsApp us your city and operator — our team will tell you which Siglift booster fits.
Yes — when your data is slow because of weak signal. A booster raises indoor signal strength so your phone connects on better 4G/LTE, which usually means faster, more stable data and clearer VoLTE calls. It cannot increase speed beyond what the tower itself provides.
Coverage depends on the model and the outdoor signal strength. SIGLIFT home models cover roughly 1,500–3,000 sq.ft, high-gain models cover up to 5,000 sq.ft, and the SL-850-27DB covers up to 10,000 sq.ft. Larger or multi-floor buildings add extra indoor antennas using power splitters. Share your floor area and we will recommend the right setup.
No. Siglift kits are plug-and-play: mount the outdoor antenna where signal is strongest (usually the roof or balcony), route the cable to the booster, place the indoor antenna in the area you want covered, and power on. Our technical team guides you step by step by phone or WhatsApp.
Price depends on the model, the area you want to cover and how many indoor antennas you need. Share your requirement through the enquiry form, a call or WhatsApp and we will send you the best price along with a model recommendation.
Every SIGLIFT booster comes with a 1-year warranty, free shipping across India, cash on delivery, a 10-day return policy and 24x7 technical support.
