Auto Message After CallAuto Message After Call not working: fixes for missing messages
When Auto Message After Call is not working, one of a short list of settings is almost always the reason. Work down the table, then contact us if it still fails.
When Auto Message After Call is not working, check that the call type is on, a template is active, the caller is not filtered, and battery limits are off.
The app runs six checks after every call and gives up as soon as one says no: the SIM, the call type, the saved-contact and exclude filters, the subscription, the 7-day cooldown, and an active template for that call type. A message that never arrives usually means one of those checks said no, and the app was working as set up. The other common cause is the phone itself: several brands pause background apps to save battery, so the app never notices that the call ended. Messages that arrive late are often queued because the phone was locked when the call ended; they send after you unlock.
Auto message after call not working: fix table
| Symptom | Likely cause | Fix |
|---|---|---|
| No message after missed calls | The Missed trigger is off or has no active template | Settings: turn on Missed; Templates: mark a missed-call template active |
| Saved contacts never get messages | Exclude All Contacts is on | Turn it off in Settings if you want contacts messaged |
| A regular caller got nothing | The number was messaged in the last 7 days | Expected: the cooldown stops repeats |
| Nothing on calls to one SIM | SIM preference excludes that SIM | Settings: choose Both SIMs |
| WhatsApp opens but does not send | Accessibility auto-send is off | Turn on auto-send, or tap Send yourself |
| Works for a while, then stops | The phone stopped the app in the background | Remove battery limits for the app (brand steps below) |
| Message arrives later | The phone was locked when the call ended | Expected: it sends after unlock |
| Nothing sends at all | Subscription inactive | Check the plan on the pricing page |

Auto message after call not working FAQ
Why does Auto Message After Call stop working after a few hours?
Auto Message After Call stops when the phone pauses it to save battery. Remove the battery limits for the app using the steps for your phone brand.
Why did one caller not get a message?
Most often the number was already messaged in the last 7 days, or it is a saved contact and Exclude All Contacts is on.
Can I see why a message was skipped?
Work through the fix table in order: SIM, call type, contact filters, subscription, cooldown, then template. The first one that does not match is the reason.
What does "never auto sleeping apps" mean on Samsung?
It is the Samsung list of apps that One UI never puts to sleep. Add Auto Message After Call there, and avoid other battery modes that can take it off the list.
How to stop Samsung from putting apps to sleep?
Open Settings, Battery, Background usage limits, Never auto sleeping apps, and add the app. Turning off Put unused apps to sleep also helps.
What is autostart permission in Android?
On Xiaomi, Redmi, POCO, OPPO, Vivo and Realme phones, autostart lets an app start by itself after a reboot or in the background. Without it, this app cannot notice calls.
How to allow autostart?
Open the app's info screen from Settings, Apps, then turn on Autostart or Auto-launch. The exact name depends on the brand and Android version.
Why does WhatsApp open but the message is not sent?
Auto-send is off, or Android switched off the Accessibility service after an update. Turn it on again in Android Settings, Accessibility.
Why did the message go to WhatsApp instead of WhatsApp Business?
The target app is set to WhatsApp in the app settings, or WhatsApp Business is not installed, in which case the app falls back to the other one.
Why do some messages arrive a few minutes late?
When several calls end close together, messages are queued about 30 seconds apart, a little longer on mobile data or when memory is low.
Why does the caller name show as a number?
The caller is not saved in your contacts, so the app has no name to insert. Save the contact, or write the template so it reads well without a name.
The attachment did not send. What should I check?
Each template takes one file up to 10 MB. Larger files are rejected; compress the PDF or video and attach it again.
How do I contact support fastest?
Message +91 73750 92569 on WhatsApp with your phone model, Android version and the call type that failed.
Does uninstalling and reinstalling help?
Rarely. Reinstalling resets permissions, which you must grant again. Check the battery and Accessibility settings first.
Why did it stop working after a phone update?
System updates sometimes reset battery and Accessibility settings. Re-add the app to the never-sleeping list and switch auto-send on again.
