‘Server Unreachable’ When Making A Call? Methods To Resolve It [2022]

On my mobile phone, it says “Server Unreachable.” What does this mean?

When a mobile phone displays a server unreachable message, it is usually because it is not connected to a network and is therefore not able to access the server. The signal on your phone may be low or not working if your network provider has an outage in your area.

When making a call, try again if you receive an “unreachable server” error. Try calling from another phone after 25-30 minutes, or contact your cellular provider if it doesn’t work.

Further, you may notice that your phone isn’t working properly, such as having too many apps running in the background or having a low battery. 

It is possible that any Facebook service, such as opening Instagram posts, will not work due to the lack of connection to the 3G/4G LTE or 5G networks.


A server is unreachable error on a mobile phone can have several causes:

  1. Unfortunately, the phone you are using does not have an internet connection. 
  2. If you do receive a signal, it is weak or nonexistent. 
  3. It seems that the server is experiencing some difficulties responding to your connection. 
  4. It appears that there is currently an outage in your area, and you will have to wait for it to be resolved.
  5. There is a problem with the VPN you’re using and the app that you are trying to use.
  6. Your phone may experience problems when too many apps are running in the background.

When the phone’s connection with its carrier is down, the error “server unreachable” appears. There may be a problem on your end, or there may have been an issue on the provider’s end.

An unreachable server message is one of the most common errors that is caused by poor cellular connections.

  1. The call is being blocked by the person who is making the call.
  2. Perhaps the person you are trying to reach has changed their phone number. 
  3. Perhaps there is insufficient reception in the area where you are calling from.  
  4. It is possible that the network of your carrier may be experiencing a problem at the time.
  5. You may have temporarily lost contact with your carrier as a result.
  6. The consequence of this may be that your carrier will be unable to provide you with service. 
  7. You might have an issue with your phone’s battery or SIM card.


When your phone says “server unreachable,” what does this mean?

If your signal is weak or the line-of-sight from the cell tower to your phone is blocked, you can see the “server unreachable” error message on your smartphone.

  1. The network connection on your phone might be down.
  2. If this is the case, you may need to check whether you have correctly inserted your SIM card.
  3. In this case, you may need to update the software on your phone.
  4. If you are attempting to call a particular number, then there may be a problem.
  5. Perhaps the airplane mode is on in your phone.
  6. It is possible that the SIM card is not inserted correctly, or that it is damaged. 
  7. You are beyond your carrier’s coverage area.

In some areas, service providers may have limited coverage, or trees and buildings may block the line-of-sight between cell towers, which will result in a weak connection and this error.

Depending on the type of phone you own, there may also be other reasons why you may be experiencing this issue. There is a possibility that your SIM card will need to be replaced or updated with new information from your service provider when the error occurs when you try to make a call. 

When signal coverage has been interrupted for some time and then suddenly restored (increased calls volume), this can occur.
