How to Auto Dial a Number on Android: One Number, or a Whole List

It depends which problem you have. To keep retrying one busy number, use your dialer's built-in redial or RMDialer's free Auto redial, which stops when someone answers: no subscription needed. To have one call happen later, a reminder is enough. To dial a whole list by itself for business, you need an auto dialer app: import the list, press start, and it calls each number in turn.

Install an auto dialer app and make it the phone app, then load a list from Excel or CSV, a connected Google Sheet or API, your assigned leads, the call log or a status filter. Set which SIM to dial from and the gap between calls, then press Start and talk. A good one shows an after-call sheet between calls so the outcome is saved before the next number rings.

Only in the narrow sense of redialling one busy number, which the built-in dialer already handles on most phones. Android will not call through a list on its own, so anything list-based needs an app that holds the list, dials in order and stops when you tell it to.

An auto dialer app calls a list of phone numbers one after another so the caller never types a number. On Android, an app like RMDialer runs the session on the phone itself using the SIM already in it: you pick a list from Excel, a Google Sheet, an API or assigned leads, press start, and the app dials each number in turn while you mark the outcome between calls.

A business dialer app replaces the default phone app on an Android phone with one made for selling: caller ID from your own leads, the last remark on screen when a customer rings, two-tap status and follow-up after each call, automatic WhatsApp, and a call log that filters by lead status. It is a personal CRM for one owner and a team system when several people use it.

The dialer is free forever. Install it, make it your phone app and you keep the keypad, contacts, call log, caller ID, spam screening and your call analytics with no account, no payment and no expiry date. Free WhatsApp sends are included every day once you make a free account. What you pay for is the memory around the call: the lead status, the remark and the follow-up reminder saved against every number, plus list auto dialing, team reports, backup and WhatsApp automation.

Yes. There is an iPhone app as well as the Android one, and it carries every feature except the native call log: leads, statuses, remarks, follow-up reminders, WhatsApp, templates, clients and team sync all work on iOS. Apple opens the call log to no app, so calls made on an iPhone are not recorded into the history by themselves, and only Android lets RMDialer become the phone app that answers with the customer on screen. The iPhone app is free on the App Store for iOS 17 or newer. The Web CRM works in any browser, including Safari.

For small and mid-sized Indian teams the best fit is a SIM-based auto dialer that runs on the phones they already own, because customers answer normal mobile numbers and there is no per-minute bill. RMDialer is that kind: the dialer is the phone app, the lead CRM, WhatsApp automation and team reports are in the same price, and the basic dialer is free with no login.

SIM-based auto dialer apps that publish their prices list about ₹159 to ₹176 per user per month on yearly plans (their own sites, checked 22 Oct 2026); cloud dialers with virtual numbers charge a seat price and add per-minute charges. RMDialer is ₹159 per user per month on the yearly plan, plus taxes, with the auto dialer, lead CRM, WhatsApp automation, team reports and the Web CRM all included in that one price.

Software that handles what happens around every business call: knowing who is calling, seeing their history before answering, saving the outcome after, queuing missed calls for a call-back, sending the follow-up message and reporting it all per employee. In a mobile business it runs inside the phone dialer rather than on a call-centre server.

The app becomes the phone's dialer, reads a list you give it and places each call over the SIM the same way you would by hand, only without the typing. After each call it waits a few seconds (the gap you set), shows a two-tap outcome sheet, then dials the next number. Numbers that did not answer can be rung again in a fresh session later.

Yes. Save the sheet as Excel or CSV with a mobile number column (name and any other columns are optional), import it in the app, and start a session. The dialer calls the rows in order and lets you mark each outcome. The same works from a Google Sheet, which can also be connected as a live source so new rows import themselves.

Five to ten seconds. That is enough to save the outcome of the last call and glance at the next lead's details without breaking rhythm. Set it longer, 15 to 20 seconds, for teams that write a proper remark after every call, and shorter for confirmation or reminder campaigns where the script is fixed.

A power dialer calls one number at a time for one agent and waits for that call to end, so every answered call has a person ready. A predictive dialer calls several numbers at once and connects the ones that answer to whichever agent is free, which needs a call-centre server and causes dropped "silent" calls. Mobile auto dialers like RMDialer are power dialers on a SIM.

In RMDialer the caller can skip any number during a session. For retries, switch on Call again if not answered: each missed person gets a limited number of extra rings at a pause you pick, without holding up the rest of the list. You can also filter the busy and unanswered numbers and start a fresh session later, ideally at a different hour, without re-importing the sheet.
