How to troubleshoot EMERGENCY CALLS ONLY bug on Galaxy S10 | fix No Service issue
EMERGENCY CALLS ONLY can occur for a number of factors. Learn how to deal with this bug by following our suggestions below.
EMERGENCY CALLS ONLY fix #1: Reboot the device
Refreshing your S10 is an important troubleshooting first step in this case. EMERGENCY CALLS ONLY bug sometimes occur when a device temporarily loses connection from a cell tower, like when you’re travelling. Once you’re in a location with good service, EMERGENCY CALLS ONLY disappears. In some cases though, this does not happen and the bug sticks. You’ll need to manually turn off the device in order to refresh the system. Make sure to do a soft reset to achieve this. Here’s what you need to do:
- Press and hold the Power + Volume Down buttons for approximately 10 seconds or until the device power cycles. Note: Allow several seconds for the Maintenance Boot Mode screen to appear.
- From the Maintenance Boot Mode screen, select Normal Boot. Note: Utilize the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Also, allow up to 90 seconds for the reset to complete.
EMERGENCY CALLS ONLY fix #2: Check if cellular service is working
If nothing changes after restarting your S10, the next troubleshooting step that you can do is confirm there’s no problem with network services in your area. If you have another phone that’s compatible with your network, use that to check. If the second phone shows the same bug, you must contact your network operator for help. There must be a problem with your carrier’s service where you’re at so it’s good if you can get first-hand confirmation from them.

Afterwards, turn your phone back on and see what happens.

EMERGENCY CALLS ONLY fix #9: Confirm IMEI is not blocked
If you got your S9 as a pre-owned device, or if you suspect that it may be blocked, you can check its IMEI status. Carriers may block a device for a variety of reasons and if that occurs, its IMEI may also be blacklisted. To check the status of your device’s IMEI, you can go to this site: imei.info.
Alternatively, you can check if your S8’s IMEI has been blocked by doing these steps:
- Open the dialer (Phone) app.
- Enter the code: (*#06#).
- If the IMEI says Null, that means that the EFS folder may be corrupted, or may had been blocked. In this case, you can try to reflash the firmware and see if that will restore the default EFS folder. If that won’t work, your S8 will never be able to connect to any network.
Some carriers may block users from accessing advanced menus thru the dialer app. If nothing happens after you enter (*#06#), that means your S8 can’t open advanced menus.
