Jio 4G Speed: How to Increase and Improve It

Updated 6 November 2026 · Standard formula, shown below

This article explains why your Jio 4G speed may be slow and provides practical, step-by-step methods to increase it. You’ll learn about network settings, phone configurations, and common fixes that can improve your data speeds on Jio’s 4G network.

Understanding Jio 4G Network

Jio, launched in 2016, is a major Indian telecom operator that offers 4G LTE services across the country. Its network uses LTE (Long-Term Evolution) technology, which provides high-speed data for browsing, streaming, and downloading. Jio’s 4G operates on bands like 850 MHz (Band 5), 1800 MHz (Band 3), and 2300 MHz (Band 40). The actual speed you experience depends on several factors, including your location, network congestion, device capability, and signal strength.

Factors Affecting Jio 4G Speed

Several elements influence your Jio 4G speed:

Signal Strength: Walls, buildings, and distance from the tower weaken the signal.
Network Congestion: During peak hours (evening), many users share the same tower, reducing speed.
Device Capability: Older phones may not support all LTE bands or carrier aggregation, limiting speed.
SIM Card Condition: A damaged or old SIM card can cause connectivity issues.
Background Apps: Apps running in the background consume data and bandwidth.
Network Settings: Incorrect APN or network mode settings can hamper performance.

How to Check Your Current Jio 4G Speed

Before making changes, measure your current speed to have a baseline. Use a speed test website or app (like Ookla’s Speedtest) to check download and upload speeds. Ensure you are in an area with good signal (check the signal bars) and close other apps that use data. Run the test a few times at different times of day to get an average.

Step-by-Step Methods to Increase Jio 4G Speed

Here are effective methods to try, from simplest to more advanced:

Restart Your Phone: A simple restart can refresh the network connection.
Toggle Airplane Mode: Turn on Airplane mode for 10 seconds, then turn it off. This forces the phone to reconnect to the network.
Check Signal Strength: Move to a window or open area. If you’re indoors, try moving closer to a window or go outside.
Reset Network Settings: Go to Settings > System > Reset Options > Reset Wi-Fi, mobile & Bluetooth (on Android) or Settings > General > Reset > Reset Network Settings (on iOS). This clears saved networks and Bluetooth connections but also resets mobile network settings to default.
Update APN Settings: Ensure your Access Point Name (APN) is set correctly for Jio. Usually, it’s ‘jionet’ with no username/password. Go to Settings > Network & Internet > Mobile Network > Access Point Names. If missing, add a new APN with name ‘Jio’, APN ‘jionet’, and leave other fields default.
Change Network Mode: On Android, go to Settings > Network & Internet > Mobile Network > Preferred Network Type and select ‘LTE (4G)’ or ‘LTE/4G (Preferred)’. Avoid ‘3G’ or ‘2G’ modes.
Clear Cache of Heavy Apps: Apps like YouTube, Instagram, and browsers store cache that can slow down performance. Clear cache via Settings > Apps > [App] > Storage > Clear Cache.
Use a Different SIM Slot: Some phones have dual SIM slots, and one may support 4G better. Try switching the SIM to the other slot.

Advanced Tips for Power Users

If the basic steps don’t help, try these:

Use a 4G Signal Booster: A signal booster (repeater) can amplify weak signals, but ensure it’s legal in your region and compatible with Jio’s frequencies.
Change Your Location: Move to a different part of your home or office. Use apps like ‘OpenSignal’ to find the nearest Jio tower and position yourself closer.
Update Your Phone’s Software: Manufacturers often release updates that improve network handling. Check for updates in Settings > System > Software Update.
Disable Data Saver: If you have Data Saver mode enabled, it restricts background data. Turn it off in Settings > Network & Internet > Data Saver.

Common Problems and Fixes

Here are typical issues users face and their solutions:

Slow Speed at Home: If speed is slow indoors, try using Wi-Fi calling if your phone supports it, or move to a room with better signal.
Speed Drops During Peak Hours: This is due to congestion. Try using the internet during off-peak hours (early morning or late night).
Phone Shows ‘4G’ but No Internet: Check APN settings, toggle airplane mode, or restart. If persists, contact Jio support.
Speed Slow After Recharge: Ensure your data pack is active and not expired. Sometimes, after a recharge, the network takes a few minutes to update.

Frequently Asked Questions

Why is my Jio 4G speed slow even with full signal?

Full signal bars don’t always mean fast speed. Network congestion, your phone’s LTE band support, or background apps can still limit speed. Try the steps above, especially resetting network settings and checking APN.

Does using a VPN increase Jio 4G speed?

Generally, a VPN can decrease speed due to encryption overhead. However, if your ISP is throttling certain services, a VPN might bypass that and appear faster, but it’s not a guaranteed fix.

How can I check which LTE band my phone is using?

You can use apps like ‘LTE Discovery’ or ‘Network Signal Info’ (available on Play Store) to see the current band. Jio primarily uses Band 40 (2300 MHz) and Band 3 (1800 MHz).

Will changing my SIM card improve Jio 4G speed?

If your SIM is old or damaged, replacing it can help. Visit a Jio store and request a new SIM (usually free if under warranty).

Is there a way to increase Jio 4G speed without any apps?

Yes, most methods don’t require apps: restarting, toggling airplane mode, moving to better signal, resetting network settings, and updating APN are all app-free.

Does Jio throttle unlimited data plans?

According to Jio’s fair usage policy, after a certain high-speed data limit, speeds may be reduced to 64 kbps or 128 kbps, depending on the plan. This is not throttling but a policy. Check your plan details.
