How To: These Auto-Redial Apps Can Call Busy Phone Lines Over & Over Again for You Until You Get Through

These Auto-Redial Apps Can Call Busy Phone Lines Over & Over Again for You Until You Get Through

Busy phone lines are nothing new. Just ask any radio station that holds a viral call-in contest. These days, however, the most active lines around aren't so fun — your state's unemployment office is receiving record-shattering numbers of calls, making it extremely challenging for you to get through. However, there are apps out there that can help you break through the noise.

They're called "auto redial" apps, and they perform just as they sound — the app dials a number for you, but if the line is busy and the call disconnects, the app simply redials on its own, saving you the trouble of doing it yourself. Let the app continue to redial and redial, and eventually, you should break through to a real human on the other end.

Why We Need Auto Redial Apps

Auto-redialers are great for calling your state's unemployment office, a local radio contest, the DMV, a state representative or another government official, or even just your grandmother who's still using dial-up internet. If you're getting a busy tone over and over again, they help reduce your workload.

For those of you who've used landlines before, you may know the feature as "continuous redial," but phone companies use different names such as repeat dial, busy redial, or busy number redial. It even has its own national shortcut that works with most landlines — *66 to start it after a busy signal call and *86 to stop it.

However, cellular carriers do not provide the same service codes as landlines, and continuous redial is one that was skipped by wireless providers. Also, smartphone manufacturers have yet to embrace a built-in software tool to help you auto redial numbers, even though Samsung appears to have had an auto-redialing feature in the past on some Galaxy models.

All major phone manufacturers have the double-tap redial feature in the built-in phone app, where you tap the green call button after ending a call to bring the number up again, then one more tap to call it. But that's a lot of tapping on your part, and that's where third-party auto redial apps come in.

Which Auto Redialer Apps Are Best

These types of apps are only available on Android. If you're an iPhone user, you're out of luck as far as apps are concerned. The reason? Android has fewer restrictions than iOS when it comes to apps that take advantage of your smartphone's system. So Android has no problem with apps using the OS and phone functions on their own, while iOS makes that impossible.

If you simply search "auto redial" on the Play Store, you'll be met with a literal sea of options. Seriously, there are a lot of apps out there. For the most part, all these apps do the same thing — auto redial when the line disconnects. But some are better than others, offering some useful features you might like to take advantage of. We take a look at five popular options from the Play Store, to see what makes these very similar apps different from each other.

You should know, according to a few auto redial app developers, Android makes it impossible for their apps to recognize a busy signal. That means that the apps won't end the call automatically if it hits one of these tones. Instead, you'll either need to hang up manually or simply wait for the call to time out. Either way, the app should begin dialing again once the call is disconnected.

App 1: Auto Dialer Expert

If you're looking for pure customization with your auto redialer, Auto Dial Expert might just be the app for you. The program offers the ability to tweak almost all of its settings, from the number of calls to call duration and even custom themes.

While other options on this list offer maximum calls anywhere from 101 to 9,999 calls, Auto Dialer Expert places no limit here whatsoever. That said, you can choose to limit how many calls the app places, anywhere from one call, all the way to, seemingly, infinity.

The same can be said for the call duration. You don't need to decide to limit your call duration, but if you want to, you can choose for the app to hang up the call immediately after a connection, all the way through cutting the call off at 23 hours, 59 minutes, and 59 seconds.

However, there are three ways to take advantage of its auto-dialing capabilities. First, you can use your regular phone app with it, but you cannot set the duration of a call this way. Second, you can use it as your default dialer, where you make calls via it and not your phone app. One way to do so is to dial until you get through, so when someone picks up, it ends its process. The other way is to set parameters such as call duration, number of calls, delay, etc.

If you have a lot of calls to make, Auto Dialer Expert has your back. It supports an "auto redial list," which lets you string together a list of numbers that the app will work through. Each number on the list also has its own settings, so you can choose how many attempts the app will make with each call, as well as how long each call will last once connected. The app also lets you import and export CSV lists, which will save you a ton of time from having to enter each number by hand manually.

If you dive into Auto Dialer Expert's settings, you'll find some extra features that really round out the app. You can choose either a light or dark theme, or you can match the system default; you can control whether or not the app is your phone's default phone app; and you can choose whether the speakerphone is enabled by default when placing a call.

The app does contain banner ads, but they aren't annoying enough to care. It also includes three in-app purchase options for the full premium version without ads ($2.49), a premium version with ads ($0.99), and an ad-free version without premium features ($1.49). What those premium features are is unknown at this point.

App 2: Auto Redial Call | Fast Call ReDialer

Auto Redial Call has one main issue — ads. The ads plague the app, popping up without notice. Of course, they're full-screen ads, too, not just banner ads like you see in Auto Dialer Expert. Still, if you can look past these interruptions, you might find Auto Redial Call is a good option for you.

A big sell for this app is the number of calls you can place. It's not technically limitless, but the app lets you set up to 9,999 recurring calls. I can't imagine how much time placing 9,999 calls would take, so it's effectively a limitless amount. On top of that, you'll find you can choose to auto redial anywhere from one second to 5,000 seconds.

While the app boasts about a feature where you can auto-end a call after one to 500 seconds or one to 500 minutes, reviews don't speak too kindly about how well the feature really works. The developers acknowledge the feature might not work "on specific devices," but offer no mention of which devices those might be.

Like Auto Dialer Expert, Auto Redial Call offers a dial list. With a little effort at the start, you can set up a list of numbers you'd like to redial. However, unlike Auto Dialer Expert, you can't customize your settings per individual number. Your overall settings apply to all numbers in the list. However, you can import a CSV file, so you don't need to enter all these numbers in the first place manually.

Unfortunately, there is no in-app purchases to remove ads or gain other features.

App 3: Auto Redial

It certainly isn't the flashiest app on this list, but Auto Redial is only second to Auto Dialer Expert when it comes to customization. It's also dual-SIM-compatible if you're looking for an app that can take advantage of your smartphone's two SIM cards.

Firstly, let's check out our limits: The app enables you to go up to a maximum of 2,001 calls, and while far from being limitless, it's a lot of calls. You can choose to make the time between each call as little as one second or as long as 300.

While the app doesn't have a traditional call list like the first two options here, it does have a function for scheduling calls for the future. As an alarm, you can choose to either schedule a call for a specific time and day or schedule one that recurs as many times as you like.

You'll also find useful features here like automatically turning on speakerphone when initiating your calls, alerts before the app starts to dial on schedule, and auto-ending dialing if the call duration exceeds five minutes. Like Auto Dialer Expert, the app is compatible with light and dark mode, as well as a setting to match the system theme.

We've had friends that have used this app for reaching their unemployment office, and they've had success with it. So while it's not as feature-filled as the previous two apps, it gets the job done. The app has banner ads, but it does have an option to purchase a no-ads version for a hefty $7.99 price tag (the banner ads aren't that annoying).

App 4: AutoRedial - Fast Redialing Made Easy

AutoRedial isn't a flashy app in the slightest. It has a modest UI and feature set. That said, it's not a bad choice if you're looking for something simple to place call after call on your behalf.

With the first three apps on our list, the name of the game was either customization, a variety of features, or a combination of the two. AutoRedial is about as simple as it gets. Enter your desired phone number, choose whether to enable or disable speakerphone, then pick how many calls the app will place (anything between one and 101). The three buttons below "Enter Number" allow you to place a call, end a call, and access your contacts. That's about it.

Well, at least as far as the main screen is concerned. If you head to the settings, you'll find a few other options. You can choose to auto redial after zero seconds, all the way to 60 seconds; enable or disable the display while redialing; have the speaker on or off; use "Smart Audio Redial," which does not explain how it works; and choose your number of call attempts, from one to 101.

But that's not quite all Auto Redial has to offer. From the hamburger menu, you can clear your call history, view recent calls, and check out your favorites. You can even see any new features the developer wants to highlight, although it's unclear how old the list really is.

This is the only app on our list with zero ads and zero in-app purchases.

App 5: Auto Redial | call timer

If you thought AutoRedial was simple, just wait until you see Auto Redial (not to be confused with App 3's Auto Redial name). The app's main screen is the definition of bare-bones, offering just enough features to call through to whatever number you need to. That said, dig deep enough, and you'll find some other settings that might make this Auto Redial worth your while.

When you first boot up the app, you'll see a straightforward screen — you can choose to auto end the call, anywhere between zero and 60 seconds or zero and 60 minutes (zero meaning the call won't auto end). Underneath that, you can choose your auto redial intervals, anywhere between one and 60 seconds or one and 60 minutes.

You wouldn't be mistaken for thinking these are the only features the app has to offer, as it's not obvious where to find any others. But if you tap that plus (+) button, and head to Settings, you'll find a lot more options hidden away. Here, you can choose to set a vibration and/or sound alarm 10 seconds before the end of a call, which is only useful if you set a time limit for ending a call on the main screen.

You can also control whether the speaker kicks in automatically, choose from ten different background colors (no light mode option), and a priority number for contacts with multiple numbers. But the real gems are the last two options — "Enable keep talking button," which allows you to keep chatting if you have auto-end enabled, and "Call Recorder," which will record your phone calls directly to your device.

The app has ads, but you can pay $0.99 in the app to remove them.
