10 Ways to Fix a Galaxy A55 that Keeps Losing Cellular Signal

Your Samsung Galaxy A55 relies on a strong cellular signal to make calls, send texts, and browse the internet. When that signal consistently drops, it can be a major inconvenience.

There are several reasons why a smartphone might experience signal loss, from temporary network issues to software problems or hardware damage.

Why Does My Galaxy A55 Keep Losing Cellular Signal?

• Network outages: Your carrier might be experiencing service disruptions in your area.
• SIM card problems: Your SIM card could be damaged or improperly inserted.
• Software issues: Bugs or outdated software can affect network connectivity.
• Temporary network glitches: Sometimes, the connection to the network gets disrupted.
• Incorrect APN settings: Access Point Names (APNs) configure your phone’s network settings.
• Faulty antenna: Your phone’s internal antenna could be damaged.

1. Check for network outages

You need to check for network outages because widespread service disruptions from your carrier can be the cause of your signal loss, and are entirely outside of your control.

How it’s done:

1. Check your carrier’s website: Look for service announcements or outage maps.
2. Contact your carrier’s customer support: Ask directly about outages in your area.
3. Utilize social media: Search for reports from other users in your area.

If it doesn’t seem like a network outage is causing your signal problems, let’s try a simple fix within your phone itself.

2. Remove and reinsert the SIM card

Removing and reinserting the SIM card can help re-establish a fresh connection with the cellular network, potentially fixing signal issues caused by improper seating or minor glitches.

How it’s done:

1. Turn off your phone: Prevent potential damage to the SIM card or phone.
2. Locate the SIM tray: Refer to your device’s manual if unsure.
3. Eject the SIM tray: Use the SIM ejector tool or a paperclip.
4. Remove the SIM card: Handle it carefully by the edges.
5. Reinsert the SIM card: Ensure correct orientation (gold contacts down).
6. Push the SIM tray back in: It should click into place.

Transition sentence: If you’re still experiencing signal instability after reinserting the SIM, let’s try a quick refresh of your network connection.

3. Toggle Airplane mode on and off

Toggling Airplane mode on and off forces your phone to quickly disconnect and then reconnect to the cellular network, potentially resolving temporary glitches that may be causing signal issues.

How it’s done:

1. Access the Quick Settings panel (swipe down from the top of the screen).
2. Locate the Airplane Mode icon (it looks like an airplane).
3. Tap the icon once to turn Airplane Mode ON (this will disable all wireless connections).
4. Wait a few seconds, then tap the icon again to turn Airplane Mode OFF.

If you’re still experiencing signal drops, let’s move on to another solution.

4. Restart your phone

Restarting your phone can clear temporary glitches and refresh the system, often resolving issues like signal loss.

How it’s done:

1. Press and hold the power and volume down buttons: This brings up the power options menu.
2. Tap “Restart”: Your phone will turn off and then automatically power back on.

If restarting doesn’t improve your cellular signal, let’s explore other potential fixes.

5. Select network operator manually

If the above steps don’t resolve the issue, you can try manually selecting a network operator, forcing your phone to connect to a specific carrier’s signal.

Here’s how to do it:

1. Access your phone’s network settings.
2. Find the option for “Mobile networks” or “Network operators.”
3. Turn off automatic network selection and choose “Select network” or a similar option.
4. Wait for your phone to scan for available networks.
5. Select the desired network operator from the list.

If manually connecting to a network doesn’t solve the problem, it’s possible the issue might lie deeper within the phone’s configuration or even the SIM card itself.

6. Reset mobile network settings

Resetting mobile network settings can resolve issues caused by incorrect configurations or glitches related to Wi-Fi, Bluetooth, and cellular data connections.

Here’s how to reset mobile network settings on your Galaxy A55:

1. Open the Settings app on your Galaxy A55.
2. Navigate to “General management.”
3. Tap “Reset.”
4. Select “Reset Mobile Network Settings.”
5. Confirm the reset by entering your PIN or password (if required).

If resetting network settings doesn’t restore your cellular signal, the issue might be with how your phone connects to your carrier’s network.

7. Test the SIM in another phone

Testing the SIM in another phone isolates whether the problem lies with the SIM card itself or your Galaxy A55.

Here’s how to do it:

1. Power off your Galaxy A55 and carefully remove the SIM card.
2. If possible, find another phone compatible with the SIM card’s size (standard, micro, or nano).
3. Insert the SIM card into the other phone and power it on.
4. Try making a call or using mobile data on the other phone.

If you can still make calls and use data on the other phone, the issue likely lies with your Galaxy A55.

8. Check APN settings

Checking APN settings is important because they determine how your Galaxy A55 connects to your carrier’s data network, and incorrect settings could explain the signal loss.

Here’s how to access and check APN settings on your Galaxy A55:

1. Go to Settings on your Galaxy A55.
2. Tap on “Connections” then “Mobile networks.”
3. Find “Access Point Names” (APN) and tap on it.
4. Review the details listed for the current APN.

If checking APN settings doesn’t resolve the cellular signal loss, there might be a more complex issue at play.

9. Factory reset your phone

A factory reset wipes your phone clean and removes any software glitches that might be causing the cellular signal loss.

Here’s how to perform a factory reset on a Galaxy A55:

1. Back up your important data, as this process erases everything.
2. Go to Settings > General management > Reset.
3. Tap “Factory data reset” and confirm your choice.
4. Enter your PIN or password and tap “Delete all data.”

If resetting your phone to factory settings doesn’t bring back your cellular signal, it’s possible there might be a hardware issue with the phone itself.

10. Seek professional repair service

If the previous steps haven’t solved the signal loss on your Galaxy A55, seeking professional repair service is recommended to diagnose and fix any potential hardware issues.

Here’s what to expect when seeking professional repair:

1. Find a qualified phone repair technician or authorized service center for your carrier or Samsung.
2. Explain the cellular signal loss problem you’re experiencing on your Galaxy A55.
3. The technician will likely diagnose the issue and provide a repair quote.
4. Once you approve the repair, they will service your phone to resolve the hardware problem.

If even manually selecting a network and checking APN settings don’t bring back your signal, it’s possible there might be a hardware malfunction with your Galaxy A55.

Final thoughts

By following these steps, you should be able to tackle cellular signal problems on your Samsung Galaxy A55. If the issue persists after trying these solutions, contacting your carrier or seeking professional repair services is advisable.
