List of Dialer for Cold Calling: RMDialer + 5 Compared

For cold calls made from mobile phones, RMDialer is the best dialer on this list: it rings one number at a time from your own SIM, keeps a do-not-call status that removes a number from every list, retries no-answers only when you switch it on, and has a free phone dialer to start with. It costs ₹159 per user a month on yearly billing in India.

One that calls from a number a business owner will recognise and keeps a record from the very first call, because business deals take several calls. Every dialer on this list calls from the caller’s SIM; RMDialer adds a status history on each contact and an iPhone app for an owner who wants to follow the pipeline.

Five are common: preview, where you see the record and tap to call; progressive or power, one call after another per caller; predictive, several numbers per free agent; parallel, several numbers at once for one caller; and voice broadcast, a recording with nobody talking. The phone dialers on this list work the progressive way, one call per caller, which never leaves a person in silence.

A dialer that becomes the phone app and uses the phone’s own SIM, so calls look like ordinary calls. Five on this list say they work that way on Android; NLCaller’s site did not say. RMDialer is the only one whose site offers an iPhone app, although on iPhone it cannot dial a list by itself because iOS does not allow it.

Five of the six publish their prices in rupees, and NLCaller published none. RMDialer is the one that also publishes a price for buyers outside India, $29 per user per year, or $12 per user for 3 months, outside India, and its app comes in 40 languages. The others may sell abroad too; ask them for a quote in your currency.

They are close because all six charge per user and none of them carries your calls: the SIM does, on your own phone plan. Four sat at ₹159 a month on yearly billing when this page was checked, one at ₹161, and one did not publish a price. Taxes are extra on all of them.

Calling people and businesses one at a time from your own number is ordinary calling, but promotional calls to strangers are regulated in most countries. In India they fall under TRAI’s rules on unsolicited commercial calls, with DND preferences and registered telemarketers on the 140 series. This list is about the tool; the list of numbers and the rules are your responsibility.

It can help by never leaving silent calls, spacing calls, and honouring do-not-call answers instantly. It cannot stop people reporting calls they did not want. Claim your business name on caller ID apps, call people with a real reason to hear from you, and keep retries few.

On this list, RMDialer’s phone dialer is free forever with no account, and Telecalling Software lists a free forever plan on its site. All six offer a trial of the paid product, three days in each case where a trial length was stated.

RMDialer retries each no-answer one to three more times, straight away, after 5 to 30 minutes or after the list, and can also retry calls that dropped within seconds. Telecalling Software’s site describes a second pass on busy and unanswered numbers. The other four did not state it on the pages checked.

It is written by the RMDialer team, which puts its own app first. The other five are companies this site compares itself with, and every fact about them was read from their own websites on 28 September 2026. Prices and features change; their sites are the final word.

Yes, and it is one of the better uses: people who handed over a business card at a stall are strangers who at least met you. Import the list, call within a few days while the fair is fresh, and save the outcome on each call so the follow-ups do not depend on memory.

At least an outcome, such as interested, callback, not interested or do not call, a one-line remark in the caller’s words, and the date of the next call if there is one. RMDialer asks for all three on a two-tap sheet before the next number rings, and keeps the history of status changes on each contact.

On a phone dialer, typically 150 to 250 dials a day against 60 to 100 by hand, depending on how long conversations run. Cold lists have fewer connects, so the gain from not typing numbers is larger than on a warm list.

Yes, and it is the fairest test. Each offers a trial, so run the same 100 numbers through two of them on the same phone and SIM, and compare connects, time per call and how complete the records are at the end of the day.
