What Causes Dropped Calls and How to Fix Them

Dropped calls occur when a phone conversation is interrupted and disconnected before either party hangs up. The main causes include poor cellular signal, network congestion, hardware or software issues on devices, and interference. For small-business owners relying on phone communication, dropped calls can mean lost sales or frustrated customers. This article covers why dropped calls happen, how to check for problems, common mistakes, and a practical example.

Why this comes up / what goes wrong

Small-business owners often face dropped calls during important sales or customer service conversations. This can happen when sales teams use mobile phones in areas with weak cell coverage or when multiple calls overload the network. Sometimes, outdated or malfunctioning phones cause calls to drop. If your team uses text messages, email, and spreadsheets alongside calls, dropped calls can disrupt your workflow and cause missed opportunities. Understanding what causes dropped calls helps you improve your communication reliability and customer experience.

Step-by-step

1. Check Cellular Signal Strength: Look at the signal bars on your phone. If they are low or fluctuating, dropped calls are more likely. Move to a location with better reception or use Wi-Fi calling if available.

1. Inspect Network Congestion: During busy hours, cellular networks may be overloaded. Try making calls at different times to see if dropped calls decrease.

1. Test Your Device: Restart your phone and update its software. Faulty hardware or outdated software can cause call drops.

1. Verify Carrier Service Status: Contact your mobile carrier or check their website to see if there are outages or maintenance affecting your area.

1. Reduce Interference: Avoid using phones near electronic devices that cause interference or in buildings with thick walls that block signals.

1. Use a Built-In CRM Dialer: Switching to a built-in CRM dialer that integrates calls with your sales software can reduce dropped calls by optimizing call routing.

1. Consider WhatsApp and SMS CRM: For businesses operating with multiple communication channels, using a WhatsApp and SMS CRM helps maintain contact even if calls drop.

1. Monitor and Log Dropped Calls: Keep records of when and where calls drop to identify patterns and address specific issues.

Example (fictional figures)

A plumbing company in Austin, Texas, tracked customer calls over a month in 03/2024. They noticed dropped calls were causing lost revenue but did not have exact percentages. They estimated the average revenue per call is $250.

They recorded 300 calls and identified 30 calls dropped during the month.

Lost revenue calculation:

Lost calls = 30 Average revenue per call = $250

Lost revenue = 30 × $250 = $7,500

After addressing signal issues and switching to a built-in CRM dialer, the company reduced dropped calls to 10 calls in the following month with 320 total calls.

Lost calls = 10 Average revenue per call = $250

Lost revenue = 10 × $250 = $2,500

Revenue saved by reducing dropped calls:

$7,500 - $2,500 = $5,000

This example shows how identifying and addressing dropped calls can directly impact business revenue.

Common mistakes

• Ignoring signal strength issues: Not checking or moving to better reception areas leads to repeated dropped calls. Prevent this by testing signal before important calls.

• Delaying device updates: Using outdated phone software can cause call instability. Regularly update your devices.

• Overloading the network during peak times: Making many calls at once can congest the network. Schedule calls to avoid peak hours.

• Not tracking dropped calls: Without data, it’s hard to find patterns or solutions. Log dropped calls systematically.

• Relying solely on phone calls: Missing out on alternative communication channels can hurt customer contact. Use tools like WhatsApp and SMS CRM to complement calls.

• Using separate tools for calls and sales: Managing calls outside your CRM leads to inefficiency. Integrate calls with your sales process via a built-in CRM dialer.

Frequently asked questions

What is the most common cause of dropped calls? The most common cause is poor cellular signal strength, often due to distance from towers, obstacles, or building materials blocking signals.

Can Wi-Fi calling help reduce dropped calls? Yes, Wi-Fi calling uses your internet connection to make calls, which can improve call stability in areas with weak cellular signals.

Does network congestion affect dropped calls? Yes, when many users access the network simultaneously, it can become overloaded, increasing the chance of dropped calls.

Are dropped calls more common on mobile phones than landlines? Yes, mobile calls depend on wireless signals that can fluctuate, while landlines use wired connections that are generally more stable.

How can a CRM dialer reduce dropped calls? A built-in CRM dialer can optimize call routing, maintain call logs, and integrate communication with sales data, reducing manual errors and improving call reliability.

What should I do if dropped calls continue despite good signal? Check your device for hardware or software issues, contact your carrier for network problems, and consider alternative communication methods like WhatsApp or SMS.
