Send text messages is a basic, yet crucial feature of any smartphone. It’s a simple, fast, and reliable way to stay connected with friends, family, and colleagues. 

But what happens when your Samsung Galaxy Z Flip 4 suddenly stops sending text messages? This can be incredibly frustrating, especially if you rely heavily on SMS for communication.

But don’t worry, in this guide, We have included every possible solution to address and fix this problem. Let’s get started!

Fix 01: Restart the Device

This basic troubleshooting step can resolve minor software glitches and temporary bugs that may be preventing your Samsung Galaxy Z Flip 4 from sending text messages.

Here’s how to restart your Galaxy Z Flip 4:

  1. Press and hold the power key and volume down key together until the device starts to turn off and display the Samsung logo.

Once your phone restarts, try sending a text message to see if the issue has been resolved.

Fix 02: Check the Signal Strength

A good cellular signal strength is a must for sending and receiving text messages. If your Samsung Galaxy Z Flip 4 is still not sending text messages, it could be due to poor or no signal strength.

Here’s how you can check the signal strength on your device:

  1. Open the notification panel by swiping down from the top of the screen.
  2. Look at the top right corner of the screen, you will see the signal strength indicator. If you see no bars or just one bar, that means the signal strength is poor or non-existent.

If you are in a location where the signal strength is typically good but currently experiencing issues, try moving to a different location. Buildings, walls, and even weather conditions can affect cellular signal strength.

In case the signal strength is consistently poor, it might be an issue with your network provider or the account. Follow the next solution where we will guide you through how to resolve them.

Fix 03: Check the Account Balance

It could be possible that your device doesn’t send text messages because there is not enough balance in your account. This is especially true if you’re using a prepaid mobile plan. There are still some carriers and plans that charge per text or have a certain limit on the number of texts you can send within a billing cycle.

Note: This step is only applicable if you’re on a prepaid plan or if your postpaid plan has a limit on text messages. If you’re on an unlimited text messaging plan, you can skip this step and proceed to the next one.

To check your account balance:

  1. Open the dialer app on your Samsung Galaxy Z Flip 4.

If your balance is zero or not sufficient to send a text message, you’ll need to recharge your account. Once you’ve added funds to your account, try sending a text message again to see if the problem has been resolved.

Fix 04: Contact Network Provider

Sometimes, the issue of not being able to send text messages on your Samsung Galaxy Z Flip 4 may not be due to the device itself, but rather a problem from your network provider’s end. This could be due to network congestion, maintenance, or even an issue with your account.

Contact Network Provider

Therefore, before going into more technical solutions, contact your network provider. They can check if there are any known issues with their service or if there’s a problem with your account that could be causing the issue.

Fix 05: Clear Messages App Cache

The cache is a component that stores repetitive processed data for future use. It helps in speeding up the operation of apps and reduces the lag while switching between apps. 

However, over time, this cache can become corrupted, leading to various issues including not sending text messages. Clearing the cache of the Messages app will potentially resolve this issue.

Here’s how you can clear the Messages app cache on your Samsung Galaxy Z Flip 4:

  1. Navigate to the ‘Settings’ menu on your device. You can do this by swiping down from the top of the screen and tapping on the gear icon.
  2. In the ‘Settings’ menu, scroll down and tap on ‘Apps‘.
  1. In the ‘Apps’ menu, scroll down until you find ‘Messages‘. Tap on it.

Here’s how you can reset network settings on your Samsung Galaxy Z Flip 4:
