Short answer: for most Indian businesses the answer is a local virtual number from ₹349/month. Toll-free is not an upgrade — it is a different product where you pay for every inbound minute. A second SIM is fine for exactly one person and breaks the moment two people need to answer.
Two questions settle almost every case:
- Who pays for the call?
- What happens when the person holding the number leaves?
The Five Options, Side by Side
| Virtual number | Second SIM | Toll-free (1800) | Landline | Missed-call service | |
|---|---|---|---|---|---|
| Monthly | From ₹349 | Plan + handset | Higher | Rental + install | Usage-based |
| Who pays per minute | Caller | Caller | You | Caller | Neither — call is not answered |
| Cost scales with volume | No | No | Yes | No | Yes |
| Rings several phones | Yes | No | Yes | No | n/a |
| IVR menu | Yes | No | Yes | No | No |
| Call recording | Yes | Not natively | Yes | No | n/a |
| Call logs for missed calls | Yes | Handset history only | Yes | No | Yes |
| Tied to premises | No | No | No | Yes | No |
| Survives staff turnover | Yes | No | Yes | Yes | Yes |
| Signals | Local presence | Nothing | National scale | Fixed premises | Low-friction intent |
Question One: Who Pays for the Call
This is the axis people get wrong, because "toll-free" sounds like the generous option and generosity sounds like good service.
On a local number the caller pays for their own leg. Your bill is the rental, flat, whether you take ten calls or a thousand.
On toll-free you pay for every inbound minute. Your bill is rental plus a meter that runs faster the better your marketing works. A successful campaign is an unexpected invoice.
On modern Indian mobile plans, the saving you are offering the caller is close to meaningless — most callers are on bundles. You are not buying the caller's convenience. You are buying the appearance of being a large national company, and it is worth asking whether that is what your customer is checking.
For an SMB it usually is not. A customer in Pune is more likely to call a Pune number than an 1800 line, because what they are checking is proximity. See virtual number city codes in India.
Toll-free is genuinely right when: you are a national brand, callers are spread across every state with no local anchor, or you are running a recall, helpline or support line where removing every possible barrier to calling is the point. See toll-free numbers.
Question Two: What Happens When Someone Leaves
This is where the second SIM fails, and it fails quietly — eighteen months later, when the person who has been answering the business number resigns.
A SIM-based number is property held by a person. It cannot be reassigned without physically handing over the SIM, and if that does not happen, every customer who has that number in their phone is now calling an ex-employee.
A virtual number is configuration held by the business. Repointing it takes a minute and customers notice nothing.
That is the entire argument, and it is usually worth more than the monthly difference.
Where Each One Actually Fits
| Situation | Choose |
|---|---|
| Solo, want to stop sharing a personal mobile | Virtual number, ₹349 Basic |
| One person, minimal needs, already has a dual-SIM phone | Second SIM is defensible |
| Two or more people answering enquiries | Virtual number — a SIM cannot do this |
| Selling into a city you are not in | Virtual number with that city code |
| Team that changes often | Virtual number |
| National brand, callers from everywhere | Toll-free, possibly alongside local numbers |
| Support or helpline where friction must be zero | Toll-free |
| High-volume lead capture from low-ARPU users | Missed-call service |
| Retail counter with a fixed public number | Landline is still fine, but a virtual number does the same without premises |
| Thirty-plus agents with queues and rotas | Cloud contact centre |
The Second SIM, Fairly
It deserves an honest paragraph, because plenty of advice dismisses it too fast.
If you are one person, you already own a dual-SIM handset, and your only goal is to keep work calls off your personal number — a second SIM does that for the cost of a plan, and you do not need to read any further.
It stops being adequate the moment any of these becomes true:
- A second person needs to answer.
- You want to know about calls you missed, not just the ones you took.
- You want a menu, recording, or business-hours behaviour.
- The number will outlive whoever is holding the phone.
Each of those is a hard stop, not a degradation. A SIM does not do them partly; it does not do them at all.
What About a Landline?
Largely a legacy answer in India now. A landline ties the number to premises, which is precisely the dependency most businesses are trying to remove. A virtual number gives you the same fixed city code, without the install, the premises, or the inability to ring a mobile.
The exception is a fixed retail or clinic counter where the number is genuinely tied to a place and nobody needs it to follow them. Even then, a virtual number does the same job and can also ring a mobile after hours.
Missed-Call Services Are a Different Category
Worth separating, because they get compared to phone lines and they are not one.
A missed-call service captures intent: the caller rings, it disconnects, and you call back or trigger an automated response. It is excellent for lead capture, verification and campaign response at volume, and costs almost nothing per interaction.
It is not a business line. Nobody can actually talk to you on it. Most businesses that use one also have a real number. See missed-call service. For a head-to-head on response channels, read missed call vs toll-free vs SMS short code.
What Most Businesses Should Do
- Start with one local virtual number on the ₹349 or ₹499 plan, routed to everyone who should answer.
- Add toll-free only when callers are genuinely national and you have accepted the per-minute model.
- Keep the second SIM if you are solo and it is working — switch when a second person needs to answer.
- Do not buy a landline unless something specific requires premises.
Sizing is in how many virtual numbers does a business need, costs in what a virtual number should cost in India, and you can start at voice-app.edesy.in.
Common Questions
Can I have both a local number and a toll-free number?
Yes, and national brands often do — local numbers for city markets, toll-free for the national support line. Each carries its own rental.
Is toll-free more trusted by customers?
It signals scale, which is a kind of trust. For a local service business, proximity signals more. Match the signal to what your buyer is actually worried about.
Can a second SIM forward to another phone?
Basic forwarding exists on mobile networks, but it forwards to one destination, gives you no logs of missed calls, no menu and no recording. It is not equivalent.
Which is cheapest overall?
A local virtual number, for any business taking a meaningful number of inbound calls — because the caller pays for the minutes and your cost stays flat.
Can I move from one to another later?
You can add or cancel numbers at any time. What does not reliably move is the number itself, so choose before publishing it on packaging or on Google.
