The best 3 auto dialer apps for Android in 2026

RMDialer, for teams dialing their own lists from Android phones: it combines SIM-based auto-dialing, a telecalling CRM on the call screen, per-employee call tracking and automatic WhatsApp follow-up at ₹1,908 per user per year. RMDialer’s free 3-day trial lets you test it on a real list first. Telodial is the alternative if the simplest possible plan matters more than scope.

Yes. RMDialer is an auto dialer app for Android: load a list from saved leads, CSV, Excel or Google Sheets and it places the next call the moment the previous one ends, through the SIM already in the phone rather than over VoIP.

An app that places calls from a list automatically, dialing the next number as soon as the last call ends, so the caller never types a number or hunts for the next row. The better ones also show who is being called and record the outcome, which is the difference between an auto dialer and a random number generator.

RMDialer, Telodial and Dialmio all dial through the SIM in the Android phone, on either slot of a dual-SIM handset. That is what separates them from cloud dialers such as Exotel or Knowlarity, which route calls through VoIP or a rented virtual number and show the recipient an unfamiliar caller ID.

Not with a SIM-based app. There is no VoIP account to open, no virtual number to rent and no IVR to configure, and call minutes come from the mobile plan you already pay for. Cloud dialers work the other way round, which is why they need telecom onboarding before the first call.

RMDialer is ₹1,908 per user per year, which is ₹159 a month, or $29 per user per year outside India. Telodial lists ₹2,028 a year per seat and Dialmio ₹2,148, so the SIM-based field sits within ₹240 of each other and the real comparison is what each plan includes. Cloud platforms usually quote on request and bill telephony separately on top.

Partly, and the free part never expires. RMDialer’s phone dialer is free forever with no account: keypad, contacts, call log, caller ID, spam screening and call analytics. Auto dialing a list is the paid half at ₹1,908 per user per year, and a free 3-day trial opens all of it with no card.

About 18 seconds per call, which is the time spent finding a number, typing it and waiting. A caller making 80 calls a day gets back roughly 24 minutes, and a four-person team around an hour and a half. The larger gain is usually the calls that simply never got made because dialing felt like work.

It depends on the app. RMDialer, Telodial and Dialmio all carry a lead record with statuses, notes and follow-up dates, updated from the call screen. Lighter auto dialers only walk a list and leave the record-keeping to a spreadsheet, which is where pipelines quietly stop being accurate.

RMDialer can, on the official WhatsApp Business API, with a different message per call outcome and the customer’s details filled in automatically. That matters because unofficial tools that automate the consumer WhatsApp app are what get business numbers banned.

Dialing from your own SIM with an auto dialer is ordinary calling as far as the network is concerned; the app only automates the tapping. What regulation governs is who you call and about what, so respect DND preferences for promotional calls and keep a record of consent, exactly as manual dialing requires.

Teams commonly reach 80 to 150 dials per caller per day on continuous dialing, against 40 to 60 when typing numbers manually. The ceiling is talk time rather than the software, so a team having longer, better conversations will sit at the lower end and should.

A SIM-based one keeps dialing, because calls go over the mobile network rather than the internet. In RMDialer notes and outcomes queue on the phone and sync when the connection returns, which is why it suits field teams and basements. A cloud dialer stops entirely without data.

Yes. RMDialer imports from CSV, Excel and a linked Google Sheet as well as saved leads, which suits teams whose list is maintained by someone who is not the caller. Telodial and Dialmio both import CSV as well.

Search RMDialer on Google Play for Android, or ask for the iPhone build at rmdialer.com, where it is supplied on request. The free 3-day trial has every feature switched on and needs no card, and the desktop Web CRM opens in any browser once the app is set up.
