Your first reminder call, set entirely from Claude
A worked first run in Claude: one plain-English prompt, confirm your time zone, create the reminder, then place a test call to prove the phone rings.

You have connected ReminderIt to Claude and now you want to see it actually work. Good instinct: the fastest way to trust a reminder system is to make it ring your phone.
This is a complete first run, from a single sentence to a live test call, so you finish knowing the whole loop works.
Before you start
Make sure the ReminderIt connector is authorised in Claude and that your phone number is verified on your account, since that is the number ReminderIt will call.
Have your time zone in mind as an IANA name, for example Europe/London, America/New_York, or Asia/Kolkata. Claude will confirm it with you, and getting it right is what makes a reminder land at the correct local minute.
Step one: say what you want in plain English
There is no form to fill in. Type something like: "Remind me to call the dentist tomorrow at 3pm." Claude reads the intent and prepares a one-off reminder for that date and time.
You do not need to name a tool or a schedule format. Natural language is the interface; the structured details are Claude's job to fill in.
Step two: confirm the time zone
Claude should check the time zone before it commits anything, because 3pm means nothing without one. If it asks, answer with your city or region and it will map that to the right IANA zone.
If it does not ask, prompt it yourself: "Use Europe/London for that." A few seconds here saves a call arriving an hour off.
Step three: create the reminder, then test the call
With the time and zone agreed, Claude calls create_reminder to schedule it. Ask "What have you got scheduled for me?" and it will run list_upcoming so you can see the new entry in the queue.
Now the satisfying part. Say: "Ring my phone now to test it." Claude calls test_call and your phone rings within moments, reading a sample reminder aloud in a natural voice. A test call does not wait for the scheduled time; it fires immediately so you can confirm the whole path end to end.
What you have proven
In one short exchange you have created a real scheduled reminder and heard ReminderIt place a genuine outbound voice call. That is the full loop, and everything else you do from Claude is a variation on it.
From here you might make it recurring, add more times, or set a wake-up call. You can manage all of it at reminderit.com or just keep asking Claude.
