Why Does My Phone Hang Up After Four Hours?

Automatic session timeouts, phone system settings, and internet issues can disconnect the calls. Generally, some call disconnections are set by the carrier itself to prevent network overloads and resource management issues for optimal performance.

Mobile carriers have a certain call time limit to avoid network overload for fair usage, which causes calls to hang up automatically. Some prepaid and "unlimited" calling plans have hidden limits or fair usage policies to manage network traffic efficiently.

Phones and devices can overheat after running many applications continuously for several hours. It may cause the phone to hang up the call or restart to cool down automatically, generally protecting and preventing internal damage.

Poor telecom networks caused by bad weather or unavoidable system issues from the provider itself also interrupt the calls. For VoIP calls, an unstable data or wifi connection drops calls unexpectedly.

Generally, VoIP software uses built-in call time limits to manage system load from excessive resource use. Due to internal software settings or provider service agreements, certain apps may disconnect calls automatically after a predetermined time, such as 4 hours.

If you have installed an unverified or malware application on your phone, it may disrupt phone functionality and cause unusual device lagging. Malicious applications can overload your system's processes, causing disruptions such as unexpected call terminations.

Call blocking is when someone blocks or stops your number from contacting them. It stops you from contacting them on their telecom number.

Whether it's a personal or business call, make sure your device is charged and has a strong network connection to prevent calls from hanging up.

• Strong Network Signal: Check for a good signal and relocate to a location with a better network signal where you can clearly hear the other person on the call.
• Phone Charged: Keep your phone charged and turn your battery optimization setting off; some devices might disconnect calls after certain battery limits.
• Software Updated: Keep your phone software updated to avoid issues with outdated applications.
• Remove Background Apps: Remove all the unnecessary apps running in the background, preventing your phone from overheating.
• Sufficient Balance: Ensure you have sufficient balance or data to carry the call for a certain time period. In some countries, phone calls can be paid for through a monthly subscription or payment plan.
• Check SIM card: Check your SIM card and ensure it is properly inserted and not damaged.
• Contact Carrier: If you suspect a network problem, contact your carrier.

If your calls consistently hang up after a specific time, it could be due to carrier-imposed call limits, device overheating, network issues, and software settings. To avoid call disconnections, ensure a strong signal, keep your phone charged and updated, close unnecessary apps, and check call duration limits.
