TL;DR
- Wi-Fi calling: free if you have broadband; fixes your calls only, not mobile data or visitors’ phones.
- Signal booster: fixes calls and 4G for everyone on the covered networks; needs usable outdoor signal and a one-time purchase.
- Changing operator: worth it only if another network is clearly stronger inside your home — test a SIM first.
- Operator complaint: free and worth logging, but new towers rarely arrive quickly.
- Cheap unbranded booster / antenna-only: often the wrong bands or no amplification — usually money wasted.
All the options compared
| Option | Fixes calls | Fixes mobile data | Helps everyone in the building | What it needs | Typical cost |
|---|---|---|---|---|---|
| Mobile signal booster | Yes | Yes (4G) | Yes, on covered networks | Usable signal outside; correct bands | One-time, ~₹5,000–₹35,000 market range |
| Wi-Fi calling | Yes | No (uses Wi-Fi instead) | Only phones on your Wi-Fi with the feature on | Stable broadband, supported phone and operator | Free with existing broadband |
| Change operator (MNP) | If new network is stronger | If new network is stronger | Only you | A stronger network at your address | Free to port; new plan |
| Complain to operator | Sometimes, eventually | Sometimes | Yes, if fixed | Patience | Free |
| Cheap unbranded booster | Often not | Often not | — | Luck with bands | Low, but often wasted |
| Antenna / “network catcher” only | No | No | — | — | Wasted |
| Femtocell / small cell | Yes | Yes | Operator’s users only | Operator deployment | Rarely offered to homes in India |
Wi-Fi calling
Wi-Fi calling (VoWiFi) lets your phone make normal calls over your broadband when mobile signal is weak. Jio, Airtel and Vi support it on most recent phones; availability for other operators varies, so check with yours.
Pros: free if you already have broadband; nothing to install; works even in a basement with no signal.
Cons: only helps phones connected to your Wi-Fi with the feature switched on; doesn’t improve mobile data, SMS/OTP delivery can still depend on mobile signal in some cases, calls may drop when you walk out of Wi-Fi range, and nothing works during a broadband outage or power cut unless the router is on backup. Visitors, staff and customers usually can’t use it.
Best for: one or two people at home with reliable fibre broadband who mainly need calls.
Mobile signal booster
A booster takes the usable signal outside, amplifies it and rebroadcasts it indoors — see how it works.
Pros: fixes calls and 4G data; works for every phone on the covered networks, including visitors, customers and staff; no broadband needed; runs on an inverter during power cuts.
Cons: needs usable signal outside; must match the operator’s bands; one-time cost; needs an outdoor antenna and cable.
Best for: families, offices, shops, clinics, basements and anywhere mobile data matters. Start with network booster for home or network booster for office.
Changing operator
Porting your number (MNP) keeps your number and takes a few working days.
Pros: no hardware; can fix the problem if another operator has a much stronger site near you.
Cons: often doesn’t help, because the problem is the building (concrete, glass, basement), which blocks every operator. Other family members or staff may still be on the old network.
Best for: people whose friends on another network get clearly better signal inside the same room. Borrow a SIM and test before switching.
Complaining to your operator
Pros: free, and worth doing — complaints help operators prioritise upgrades.
Cons: fixes for indoor coverage usually need a new site or equipment, which rarely happens quickly for a single address.
Best for: everyone, alongside another fix. Log the complaint and keep the reference number.
Cheap unbranded marketplace booster
Pros: low upfront price.
Cons: frequently the wrong bands for your operator or circle, optimistic coverage claims, thin cable, no automatic gain control (which can cause oscillation and disrupt the network around you) and no installation help. See why the cheapest can cost more.
Best for: buyers who already know their exact band and are comfortable troubleshooting on their own.
Antenna only (“network catcher”)
An antenna has no power, so it can’t amplify signal, and phones can’t connect to an external antenna. Stickers and chips have no effect. Details in network catchers, explained.
Femtocell or small cell
A small operator-owned base station connected to broadband. It works well, but in India it is typically offered by operators for large enterprise or campus sites rather than to individual homes.
Three real-world scenarios
A working couple in a 2BHK with fibre broadband
Both phones support Wi-Fi calling and the problem is only in the bedroom. Switch on Wi-Fi calling first — it costs nothing. If calls still drop in the lift lobby or on the balcony, or mobile data matters, a small home booster is the next step.
A joint family in a three-floor kothi with a basement office
Six phones on different operators, elderly parents who don’t change phone settings, and a basement with no signal at all. Wi-Fi calling would need every phone configured and every corner covered by Wi-Fi. A booster matched to the family’s main operators, with a splitter and an antenna per floor, fixes calls and data for everyone at once.
A shop in a basement market without broadband
There’s no Wi-Fi to call over, and customers’ UPI payments keep failing. A booster is the practical fix here — see basement signal booster.
How to decide in two minutes
- Check the signal outside on the roof or balcony. No signal at all? Use Wi-Fi calling and log an operator complaint.
- Only you need calls, and you have reliable fibre? Turn on Wi-Fi calling first — it’s free.
- Several people, visitors, customers or mobile data need to work indoors? A booster is the more complete fix.
- Does a friend’s SIM on another network work well inside? Consider porting.
You can also use both: many SIGLIFT customers keep Wi-Fi calling on as a backup. Check your reading with our signal strength checker, then try the booster finder.
