4G So Slow And What Can I Do To Fix It

What Is 4G?

The term “Fourth-Generation Network” was coined by Ericsson in 2008. It refers to the fourth generation of mobile networks, which provides higher data rates for faster cellular connections than their predecessors and is commonly marketed as being capable of broadband speeds.

The three previous generations are First Generation (GSM), Second Generation (CDMA/TDMA), and Third Generation (W-CDMA/HSPA).

What Is A Slow Connection?

A common complaint with the newer radio waves is often attributed to slower connection speeds and intermittent service, which has been coined “slow connections”.

This typically happens when there are too many devices connected to your network at once or when your device isn’t picking up a signal or is not close enough to the router.

Why Is My 4G Internet Slow?

Several factors can contribute to slow 4G internet speeds. Here are detailed explanations and solutions:

  1. Network Congestion:
    • Explanation: High demand in densely populated areas can lead to network congestion, slowing down data speeds for all users.
    • Solution: Try using your device in less crowded areas or during off-peak hours to alleviate congestion.
  2. Signal Strength:
    • Explanation: Weak or fluctuating signal strength can result in slower data speeds. Distance from cell towers and physical obstacles affect signal quality.
    • Solution: Move to an area with better signal reception. Avoid places with interference, and consider using signal boosters if needed.
  3. Device Issues:
    • Explanation: Outdated software, background apps, or device malfunctions may impact performance.
    • Solution: Update your device’s software, close unnecessary apps, and restart your device. If issues persist, contact your device manufacturer for support.
  4. Data Limitation or Throttling:
    • Explanation: If you’ve exceeded your data limit, some carriers may throttle your speeds.
    • Solution: Check your data usage, upgrade your plan if needed, or contact your carrier to inquire about any speed restrictions.
  5. Network Upgrades:
    • Explanation: Ongoing network upgrades or maintenance by your carrier may temporarily affect speeds.
    • Solution: Check for carrier announcements about maintenance schedules. If the issue persists, contact your carrier for updates.
  6. SIM Card Issues:
    • Explanation: A damaged or outdated SIM card can impact connectivity and speed.
    • Solution: Ensure your SIM card is in good condition and properly inserted. If issues persist, consider getting a replacement from your carrier.
  7. Weather Conditions:
    • Explanation: Extreme weather conditions, such as heavy rain or storms, can interfere with signal transmission.
    • Solution: Wait for the weather to clear. Signals may improve once weather conditions stabilize.
  8. Carrier Policies:
    • Explanation: Some carriers may prioritize network resources based on plans or user types.
    • Solution: Check your carrier’s policies and consider upgrading to a plan with higher priority if needed.
  9. Network Compatibility:
    • Explanation: Older devices may not support the latest 4G technologies, limiting data speeds.
    • Solution: Consider upgrading to a newer device that supports the latest 4G standards for improved performance.
  10. Localized Interference:
    • Explanation: Electronic interference from nearby devices or structures can disrupt signal transmission.
    • Solution: Identify and move away from sources of interference, such as electronic devices or large structures.

Why Is My Data Suddenly So Slow?

The most common cause of a sudden data slowdown is that all the cellular towers in your area are experiencing an influx of users, causing congestion and slowdowns. This results in slower connections for everyone trying to use their phone or tablet at once! In general, you should notice this happening when there’s lots of people around (like late-night bars) – but it can happen anytime! Regularly checking how many other devices are connected to your network will let you know if things have changed outside of your home.

Here’s what we recommend: Try restarting both your modem and router; make sure they’re plugged into power outlets as well so they don’t lose connection during the process. If those steps don’t work, head to your nearest carrier store for a free data diagnostic and speed test.

In the meantime, try connecting to Wi-Fi instead of cellular data! That way you’ll be connected through a different network that may have less congestion or more bandwidth available. You can also download apps like Skype, FaceTime, Facebook Messenger – all these use WiFi connections by default so they should work well regardless of what’s going on with the cell towers in your area. And if it turns out there is a problem outside of your home (like construction), our customer service team will let you know about any possible issues we’re aware of!

If none of those solutions work then it might just be time for an upgrade; newer phones support higher speeds than previous versions of the same phone.
