Alarm Call Service: How to Set One Up in Under 2 Minutes
A phone call alarm is the only alarm that wakes heavy sleepers and anyone who silences their phone at night. Here's how to set one up on WhatsApp and try it free for 7 days.

An alarm call service does exactly what a hotel wake-up call used to do — rings your phone at a time you've chosen, so you wake up or remember to do something. The difference is that modern services like ReminderIt let you set these up yourself in under two minutes — ReminderIt starts with a 7-day free trial, no card needed — and you can schedule them to repeat as often as you need.
What Is an Alarm Call Service?
An alarm call service rings your mobile or landline at a scheduled time with a spoken reminder. You don't need an app on your phone. You don't need to be a tech-savvy user. As long as you can receive a phone call, the service works.
When the call connects, you hear a spoken message — either a default wake-up message or a personalised reminder you've written yourself. The call rings until you answer or it times out, making it far harder to sleep through than a phone alarm you've set the night before and forgotten about.
These services have existed for decades in hotel form. What's new is that they're now available to anyone, from a phone, without needing a hotel room.
Who Benefits Most from an Alarm Call Service?
Heavy sleepers who rely on multiple alarms — a phone call rings differently than a standard alarm tone and triggers a different waking response. Many heavy sleepers who sleep through three phone alarms report waking immediately when their phone rings as a call.
People taking medication with a strict timing window — a call is harder to dismiss and ignore than a notification banner. The active engagement required to end a call increases the chance of actually taking the medication.
Older adults or those without smartphones — alarm calls work on any phone, including basic handsets and landlines. There's no app to download, no interface to learn.
Anyone with an important early morning commitment — a flight, an exam, an interview, a medical appointment. When missing the alarm has serious consequences, a backup call provides genuine peace of mind.
How to Set Up a Free Alarm Call with ReminderIt
Open WhatsApp and message ReminderIt at +1 478-606-1901. There's no sign-up form and no card — your 7-day free trial starts with your first message, and the calls go to the number you're messaging from.
Say what you want in plain words: the time, whether it's a one-off or recurring, and the message you'd like to hear. You can keep it simple ('Wake me up at 6am tomorrow') or make it specific ('Call me at 5am — your flight departs in three hours, check your documents').
That's it. No new app to install. When the time comes, your phone rings and a WhatsApp message arrives with Done and Snooze buttons. Pick up and hear your reminder spoken back to you — and if you miss it, ReminderIt tries once more about five minutes later. After the trial, it's one plan at $7 a month.
Alarm Call vs Standard Phone Alarm: Key Differences
A standard phone alarm plays a tone from your device's speaker. If your phone is on silent, the alarm may not sound (depending on your settings). If you're a heavy sleeper, you'll often turn it off without fully waking. If your phone battery dies overnight, you get nothing.
An alarm call comes from the network — it rings your phone the same way a friend calling you would. It bypasses many silent-mode settings. It requires active engagement to dismiss. And because it's a genuine phone call rather than a local alarm, it often triggers a different psychological response — 'someone is calling me' rather than 'that's my alarm again'.
For truly important wake-ups or reminders, using both — your device alarm plus a scheduled call — gives you redundancy that's hard to sleep through.
Setting Recurring Alarm Calls
One of the most useful features of a modern alarm call service is recurring scheduling. Set a call for every weekday morning at 7am. Set a medication reminder for every day at 8am and 8pm. Set a weekly check-in reminder for every Monday at 9am.
Unlike a hotel wake-up call that you have to request each night, a recurring alarm call service runs automatically until you change or cancel it. You set it once and it continues — no nightly setup required.
ReminderIt also lets you skip specific dates — if you don't need the call on a bank holiday or during a period of annual leave, just tell it on WhatsApp and those dates are skipped without deleting the recurring schedule entirely.
