How To Fix LG V40 ThinQ Cannot Connect To Mobile Data Network
Problem: Hello, I’m hoping that a solution is available for my problem. I bought a Amazon LG V40 Thinq smartphone to go with a new service I am currently with which is Firstnet, provided by ATT.The phone was on their website as compatible and unlocked to ATT and Verizon. I recently noticed that I was getting internet on WiFi only. So I worked it out with Firstnet and they sent me out a new sim card to fix the problem and it did no good.ATT sim card had the same results. no internet connection, open the browser and no server found because I have no mobile data access to use with the phone. Phone has been updated and can make calls but no internet unless on wifi. Worked with Firstnet again and all setting are ok, it’s just not seeing or blocking my access to my network. Hope you can help. Thanks.
Solution: Before performing any troubleshooting steps on this device it’s best to make sure that it is running on the latest software version. If an update is available then I suggest that you download and install it first.
What you should do first in this case is to make sure that you have an active mobile data subscription and that your phone is getting a strong data signal, preferably LTE.
You should then make sure that the APN setting of the phone is set correctly to the Firstnet network.
To access the APN setting of your phone
- From the Home screen, Settings.
- Tap the ‘Networks’ tab.
- Tap More > Mobile networks > Access Point Names.
- If available, tap the Firstnet APN (the bullet point fills with green). If not available, tap the Menu key, and then tap Add APN.
- A separate APN must be added manually for the Reset to default option to appear.

In case the issue still persists then proceed with the additional troubleshooting steps listed below.
Check if the problem occurs in Safe Mode
Sometimes an app you downloaded can cause this problem. To check if this is what’s causing the problem you will have to start the phone in Safe Mode as only the pre-installed apps are allowed to run in this mode.
- With the screen on, press and hold the Power key.
- In the options menu that displays, press and hold Power off.
- When prompted to restart in Safe Mode, tap OK.
- After your device restarts, it displays Safe mode at the bottom of the screen.
If you are able to use the mobile data network in this mode then the problem could be caused by an app you downloaded. Find out what app this is and uninstall it.
Wipe the cache partition
Your phone will store temporary data in a dedicated partition in its storage space which helps the device run apps smoothly. If this data gets corrupted then issues can occur on the device. To make sure that this is not what’s causing the problem you will have to clear the cache partition of the phone.
- From the Home screen, tap Settings.
- Tap the ‘General’ tab.
- Tap Storage > Internal storage.
- Wait for menu options to finish calculating.
- Tap Free up space.
- Tap Temporary files & raw files.
- Select the following options: Cached data, Clip tray temporary files, Raw files from camera
- Tap Delete > DELETE.
Check if the issue still occurs.
Perform a factory reset
One last troubleshooting step you can perform if the phone is still unable to send an MMS is a factory reset. Take note that this will erase your phone data so it’s best to backup the phone data before proceeding.
- Back up data on the internal memory before performing a factory reset.
- From the Home screen, Settings.
- Tap the ‘General’ tab.
- Tap Restart & reset.
- Tap Factory data reset.
- If desired, tap the Erase SD card checkbox.
- Tap RESET PHONE – Delete all – RESET
You can also perform the factory reset using the hardware keys.
- Backup all data on the internal memory before performing a master reset.
- Turn off the device.
- Press and hold the Power and Volume down buttons.
- When the LG logo appears, quickly release and then re-hold the Power button while continuing to hold the Volume down button.
- When the ‘Delete all user data (including LG and carrier apps) and reset all settings’ message appears, use the Volume down button to highlight Yes.
- Press the Power button to reset the device
Once the reset is complete you should setup the APN settings of the phone again then check if the issue still occurs.
