Sign in and get 14 days free

On the first screen you choose how to get in:

  • 1„Sign in with Google”: pick your Google account and get 14 days free. No password, no card.
  • 2„Try 3 days free, no sign-in”: if you just want a quick look.

Tip: go with Google sign-in. You get 11 more days, and they stay with you even if you change phones.

🔔 Turn on notifications. Right after sign-in the app asks for them: tap „Turn on”, then „Allow”, so important messages from us reach you.

Get to know the home screen

  • 1Automation: the main switch. When it's orange and says „Automation is on”, MerkurSMS replies to missed calls.
  • 2Trial period: how many days you have left (14 after Google sign-in). Tap „+” to add more: 790 RSD for 31 days through Google Play, no subscription.
  • 3Set up main message: a shortcut to the message sent on a missed call (more in step 5).

In between is the „Messages answered today” counter, so you can see how many people MerkurSMS took care of while you were working.

Permissions: why they're needed

The first time you turn on Automation, the app explains why it needs permissions. Without them MerkurSMS simply can't do its job:

📞 Call log

To know a call was missed, and from which number.

✉️ Send SMS

To send your message to that number.

💬 Receive SMS

To see the reply, but only in conversations MerkurSMS started (e.g. someone writes „price”). It doesn't read or store your personal messages.

👥 Contacts

Only to check whether a number is in your contacts, so it doesn't text your family and friends.

🔒 Everything stays on your phone. Nothing goes to servers and nothing is sold.

  • 1Tap „Continue”. The phone then shows a few windows, one per permission. On each one tap „Allow”.

On a phone set to Serbian the button says „Dozvoli”.

My rules

In the bottom menu tap „Rules”. This is everything MerkurSMS sends on your behalf.

  • 1First message: what everyone gets when they call and you don't pick up.
  • 2Continue the chat: ready-made replies to the most common questions (price, appointment, catalog, other). Switch on the ones you need. These are the follow-up messages from step 6.

New: below is also „Phone automation”. MerkurSMS can work on a schedule, silence your phone at night and add a reminder to your calendar to call back. Turn on what you need, whenever you want.

Write your first message

Tap „First message”. This is the most important message, because everyone who calls you sees it.

  • 1Message text: write it in your own words. Not sure what to say? Tap „Use suggestion”.
  • 2When to send: right after the missed call, or after 30 seconds to 15 minutes, so it looks like you typed it yourself.
  • 3Which numbers: by default only numbers not in your contacts, and only first-time callers. We recommend leaving it that way.
  • 4„Save” in the top right. Don't skip this one 🙂

The trick that makes the difference: end your message with a question, e.g. „Are you interested in the price or an appointment?” People reply, and MerkurSMS can keep the conversation going.

Follow-up: MerkurSMS keeps the conversation going

A follow-up is the second message. It's sent only when the caller replies to the first one with a keyword from your rules. It looks like this:

📵 Missed call · 14:05
First message
Hi! I'm at work right now. Are you interested in the price or an appointment? 🙂
How much is a water heater replacement?
Follow-up: „Price question” rule
Water heater replacement starts at 3,000 RSD, depending on access. I'll get back to you as soon as I'm done here. 👍

To set up your own follow-up, in „Rules” tap a rule, for example „Price question”:

  • 1Keywords: the words the rule reacts to. MerkurSMS recognizes them without diacritics and in every grammatical case (cena, cene, cenu…). Add your own with „Add keyword”.
  • 2Automatic reply: what MerkurSMS answers. Put your real price here, or a link to your price list.
  • 3Continue the chat: if the caller replies again, MerkurSMS can continue using your other rules.
  • 4„Save”, then go back to „Rules” and check that the rule's switch is on.

No spamming: by default one number gets at most 3 messages (first + 2 follow-ups). And you still close the deal yourself: MerkurSMS doesn't book anything for you, it just keeps the person interested and sends them the info.

Turn it on and test it

Go back to „Home” and turn on the Automation switch (number 1 from step 2). When it says „Automation is on”, you're done. 🎉

🧪 Test it right away: ask someone to call you from a number that isn't in your contacts. Don't answer. A few seconds later your message arrives. Have them reply „price” and watch MerkurSMS keep going.

Stuck somewhere? Give us a call.

We'll set it up together in a few minutes. Really, call.
