7 Working Ways to Speed Up Slow Jio 4G/5G Internet

If your Jio internet speed feels slower than it should, you are not alone. Millions of Jio users in India report speeds dropping to 1–3 Mbps on 4G, even in cities with full signal bars. The good news is that most slow-speed problems on Jio 4G and 5G are caused by phone settings, not the network itself. Learning how to increase Jio internet speed often comes down to fixing your APN settings, choosing the right network mode, clearing cached data, and avoiding tower congestion traps.

Before anything else, be honest with yourself about what is realistic: no APN tweak can turn a congested tower into a fibre connection. But the steps below routinely take users from unusable speeds to smooth YouTube and WhatsApp video calls. Run a speed test on fast.com before you start, so you can measure the improvement yourself.

1. Fix Your Jio APN Settings (The jionet Method)

APN (Access Point Name) is the gateway your phone uses to reach Jio’s data network. Jio’s official APN is jionet, and Jio’s own support page confirms you should enter “JioNet” in both the Name and APN fields. Many slow-speed cases trace back to a wrong or corrupted APN after a SIM swap, phone reset, or software update.

Here is how to set it correctly on Android: open Settings, go to SIM cards & Mobile Networks (the name varies by brand), select your Jio SIM, tap Access Point Names, and either tap “Reset to default” or create a new APN. Enter these values: Name: Jio 4G, APN: jionet, APN type: default,supl, APN protocol: IPv4/IPv6, APN roaming protocol: IPv4/IPv6. Leave Proxy, Port, Username, and Password as “Not set”, and do NOT touch MCC or MNC — those are filled automatically from your SIM, and a wrong value can make the APN disappear. Save the APN, select it as active, toggle Airplane mode on and off, and restart your phone.

A warning about “speed booster” APNs: dozens of blogs promote custom APNs with strange servers, usernames, and bearer lists claiming to unlock hidden speed. There is no technical basis for these — the APN is just an address label, not a throttle control. Stick to the official jionet APN. If a third-party APN ever asks for a proxy server or username, it is at best useless and at worst a privacy risk.

2. Lock the Right Network Mode and LTE Band

Jio is an all-IP network — it has no 2G/3G fallback for data. If your phone is set to “5G/4G/3G/2G (auto)”, it can waste time hunting between modes, especially at the edge of coverage. Set your Preferred network type to “5G/4G/3G/2G auto” if you have 5G coverage and a 5G plan, or “LTE only” if you are on 4G and notice the signal dropping to weaker modes.

Advanced users can go further with band locking. Dial *#*#4636#*#* on many Android phones to open the hidden Phone information menu, where you can see which LTE band (Band 3, 5, or 40 on Jio) you are connected to. Jio’s Band 40 (2300 MHz) usually gives the fastest speeds in cities, while Band 5 (850 MHz) travels further and works better indoors. If you are stuck on a slow band, some phones let you force a band from this menu. Use this carefully — forcing a band that has weak signal at your location will make things worse, not better.

3. Switch to a Faster DNS

Every website you open starts with a DNS lookup, and your carrier’s default DNS is not always the fastest. Switching to a public DNS can noticeably speed up page loads and app connections. On Android 9 and above, go to Settings, search for “Private DNS”, and enter dns. google (Google DNS) or one.one.one.one (Cloudflare DNS). This encrypts your DNS queries too, which is a small privacy win.

Alternatively, install the free 1.1.1.1 app by Cloudflare, which applies faster DNS with one tap and adds their WARP option. Many Jio users report snappier browsing and lower ping in games like BGMI after switching DNS, because Jio’s default DNS routes can be congested during peak hours.

4. Clear Cache, Disable Data Saver, and Update Everything

Three small settings silently throttle your experience. First, Data Saver: if it is on (Settings > Network & Internet > Data Saver), Android restricts background data and compresses images, which can make apps feel slow. Turn it off when you have an active data plan. Second, clear the network cache by going to Settings > Apps, showing system apps, and clearing cache for “SIM Toolkit” and your browser. Third, keep your phone’s software and carrier settings updated — manufacturers regularly ship modem firmware updates that improve Jio compatibility.

Also check that you have not hit your daily data limit. Jio’s prepaid plans throttle you to 64 kbps after the daily quota is exhausted, and no setting on earth will fix that — only a data voucher or the next day’s quota reset. Open the MyJio app and check your remaining high-speed data before doing anything else.

5. Beat Tower Congestion With Timing and Position

The single biggest cause of slow Jio speeds in Indian cities is tower congestion: too many users on one tower between 7 PM and 11 PM. If your speed is fine at 6 AM but terrible at 9 PM, that is congestion, not your phone. Practical workarounds: move closer to a window or step onto a balcony — concrete walls and low-E glass kill LTE signals; avoid keeping your phone in a metal-heavy case; and schedule heavy downloads (system updates, Netflix downloads) for off-peak hours.

If you use Jio as a hotspot, position the phone itself well and keep it plugged in, since hotspot mode drains the battery and some phones throttle the modem when hot. An overheating phone genuinely slows its radio — if your device feels hot, let it cool down before judging speeds.

6. Reset Network Settings (The Clean Slate)

When nothing else works, reset all network settings. On Android: Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth. This wipes saved Wi-Fi passwords and Bluetooth pairings too, so note them down first. On iPhone: Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.

After the reset, your Jio APN will be re-provisioned automatically in most cases. Re-run your speed test. If speeds are still bad after a clean reset, the problem is almost certainly the tower or your plan, not your phone.

7. Check Your Plan, 5G Eligibility, and Tower Coverage to Increase Jio Internet Speed

Finally, check the things no setting can change. Jio 5G (Jio True 5G) requires a 5G smartphone, 5G coverage in your area, and an eligible plan — the MyJio app shows a “True 5G” badge if you qualify. If you are on an old 4G-only recharge, upgrading your plan is the only fix. Also verify your SIM is in the primary SIM slot; on dual-SIM phones, the secondary slot sometimes gets weaker modem priority.

To rule out a tower fault, ask a neighbour on Jio to run a speed test at the same time. If everyone is slow, raise a complaint in the MyJio app under “Network issues” — Jio does act on clustered complaints, and you will get an SMS with a service request number. Persistent area-wide slowness for weeks is also a legitimate reason to consider porting, and you can check whether your handset supports 5G properly with our guide on how to check if your phone is 5G compatible before blaming the network.
