BSNL APN Settings 2026: Correct Internet APN for 4G & 5G (Step-by-Step)
If your BSNL internet is slow, keeps disconnecting, or doesn’t work at all even though you have a valid recharge, the problem is almost always your APN (Access Point Name) settings. The good news: fixing it takes less than two minutes once you know the right values.
Quick answer: For almost every BSNL SIM in India, the correct internet APN is simply
bsnlnet. You don’t need a username, password, or proxy , just that one word, typed in lowercase, with no spaces.
In this guide, you’ll find the exact BSNL APN settings for Android and iPhone, how to set them up manually or automatically, what to do if your internet still doesn’t work, and where BSNL’s 4G and 5G rollout actually stands in 2026, so you’re not following outdated advice.
What Is an APN, in Simple Terms?
Think of your phone and the internet as two different countries.
The APN is the customs checkpoint your data has to pass through to get from one to the other. It tells BSNL’s network three things: which gateway to use to send your data, what kind of service you’re requesting (internet, MMS, or both), and how to handle your IP address.
If this checkpoint has the wrong address, your data doesn’t get through, no matter how strong your signal bars look, or how much balance you have left.
Why Getting the APN Right Actually Affects Your Speed
A wrong or corrupted APN doesn’t just slow you down; it can stop mobile data from working entirely while voice calls and SMS keep working fine. That mismatch confuses a lot of people, because it looks like the SIM is “half-working.”
A correctly configured APN does three concrete things for you:
- Lets your phone register on BSNL’s data network in the first place
- Routes your traffic through the right gateway, which reduces unnecessary latency
- Avoids the connection drops that happen when an old or duplicate APN entry conflicts with the one BSNL’s network expects
In short: the APN is the foundation. Network mode, signal strength, and site congestion matter too (more on that further down), but none of it matters if the APN itself is wrong.
Correct BSNL APN Settings (2026)
This is the only table you really need. Use it for both 3G (where still active) and 4G data on any Android phone, iPhone, dongle, or 4G router.
| Setting | Value |
|---|---|
| Name | BSNL Internet (or anything you like) |
| APN | bsnlnet |
| Proxy | Not set |
| Port | Not set |
| Username | Not set |
| Password | Not set |
| Server | Not set |
| MMSC | Leave blank (see MMS note below) |
| MCC | 404 |
| MNC | Varies by telecom circle; usually auto-filled by your SIM. Common values include 38, 51, 53, 54, and 70–75. Leave it blank if your phone doesn’t ask. |
| Authentication type | None / Not set |
| APN type | default,supl |
| APN protocol | IPv4 (or IPv4/IPv6 if your device offers it) |
| Bearer | Unspecified |
| MVNO type | None |
A note on MMS: Multimedia Messaging Service (MMS) settings used to need a separate APN entry (bsnlmms) with its own MMSC URL.
In practice, almost nobody sends MMS anymore. WhatsApp, Telegram, and similar apps have replaced it, and BSNL’s MMSC server addresses have changed over time and vary by circle.
If you genuinely need MMS working, it’s safer to call BSNL customer care (1503, toll-free) and ask for the current MMSC URL for your specific circle rather than relying on a number that might be outdated.

How to Set Up BSNL APN on Android (Step-by-Step)
The menu wording differs slightly between Samsung, Xiaomi, OnePlus, and stock Android, but the steps below work on practically every Android phone sold in India.
- Open Settings and go to Network & Internet (on some phones: Connections).
- Tap Mobile Network (or SIM & Network), then select your BSNL SIM if you have two SIMs.
- Tap Access Point Names (sometimes hidden inside Advanced).
- Tap the + icon, or Add new APN, in the top corner.
- Fill in the fields exactly as shown in the table above. Leave anything not mentioned blank.
- Tap the three-dot menu and select Save.
- Go back to the APN list and make sure the new BSNL APN has a filled (selected) radio button next to it. This is the step most people miss.
- Restart your phone, or simply toggle Flight Mode on and off, to apply the new settings.
Brand-specific quirks worth knowing:
- Xiaomi (MIUI/HyperOS): the APN menu sometimes sits under SIM cards & Mobile Networks → [Your SIM] → Access Point Names.
- Samsung One UI: look under Connections → Mobile Networks → Access Point Names.
- Stock Android (Pixel, Nothing, Motorola): it’s usually a straight path; Network & Internet → SIMs → Access Point Names.
If you can’t find the APN menu at all on a heavily customised Android skin, search your phone’s settings app for “APN” directly. Almost every manufacturer keeps the search bar functional even when they rearrange the menu structure.
How to Set Up BSNL APN on iPhone
iPhones running iOS 15 and later usually detect and apply carrier APN settings automatically the moment you insert a BSNL SIM and connect to the network for the first time. If that hasn’t happened, or your data still isn’t working, set it manually:
- Open Settings and tap Mobile Data (or Cellular Data, depending on your iOS version).
- Tap Mobile Data Network.
- Under the Mobile Data section, enter:
- APN:
bsnlnet - Username: leave blank
- Password: leave blank
- APN:
- Leave the LTE section completely blank. BSNL does not currently require a separate LTE/4G APN. The same
bsnlnetvalue carries your 4G data. - Go back, and toggle Mobile Data off and back on, or restart your iPhone.

Getting BSNL APN Settings Automatically (No Manual Typing)
If you’d rather not type anything in by hand, you have two reliable options:
- Let the SIM push it automatically. When you insert a new BSNL SIM and connect to the network, BSNL usually sends an APN configuration message automatically. Just accept the prompt when it appears. Most people who think their “APN settings disappeared” actually just dismissed this notification by mistake.
- Use the BSNL Selfcare app. The official BSNL Selfcare (or “My BSNL”) app can refresh your network profile and push settings without you touching the APN menu at all.
If neither works, your last resort is to remove and reinsert the SIM after a phone restart. This often re-triggers the automatic configuration push.
Does BSNL 5G Need Different APN Settings?
Short answer: not yet, and likely not even when it arrives. As of mid-2026, BSNL has completed its pan-India 4G rollout and is targeting a 5G soft launch starting in Delhi, with wider expansion to follow gradually rather than all at once.
Because BSNL is upgrading its existing 4G radio equipment to 5G through a software and minor hardware update rather than building a separate 5G network from scratch, the same bsnlnet APN is expected to continue working once 5G goes live in your area in the same way 4G didn’t require a new APN over 3G.
If you’re in a city where BSNL 5G eventually becomes available, your phone will simply pick up the 5G signal automatically (assuming your phone supports 5G and BSNL’s specific 5G bands). There’s no separate “5G APN” to chase down.
Troubleshooting: When the APN Is Right but Internet Still Doesn’t Work
This is the situation that frustrates people the most. Settings are correct, but data still won’t load. Here’s how to work through it systematically.
Quick Checklist Before You Do Anything Else
- Mobile data toggle is switched on.
- The correct SIM is selected for data (a very common issue on dual-SIM phones)
- Your BSNL SIM has an active data pack with balance remaining
- Network mode is set to 4G/LTE Preferred or Automatic, not locked to 2G/3G
- Flight mode has been toggled on and off once since the last change
- You’re not connected to a VPN or aggressive data-saver/battery-saver mode that blocks background data

Common Mistakes That Cause “APN Looks Right but Doesn’t Work”
- Multiple saved APNs with the same name. If you have an old, broken
bsnlnetentry and a new correct one, Android sometimes keeps selecting the wrong one. Delete duplicates and keep only one. - A stray space in the APN field. Typing
bsnlnetwith a trailing space (easy to do with autocorrect) breaks the connection silently. - Wrong SIM slot for mobile data on dual-SIM phones. Check Settings → SIM Management to confirm BSNL is set as the data SIM, not just the calling SIM.
- Restarting expectations, not the phone. Saving a new APN doesn’t always apply instantly. Always restart or toggle Flight Mode.
Step-by-Step Fix
- Verify every character of the APN :
bsnlnet,lowercase, no spaces before or after. - Reset network settings to default, then re-enter only the correct APN (this clears any conflicting or duplicate entries).
- Restart the device: not just the data toggle, the full phone.
- Check signal strength and network mode. If you’re stuck on 2G/3G in a weak coverage area, switch network mode to Automatic so your phone can fall back gracefully instead of getting stuck searching.
- Confirm your data pack is active, not just your main balance. BSNL (like most Indian telecom operators) requires a separate data add-on or plan for internet to work, even with sufficient talktime balance.
- Call BSNL customer care at 1503 (toll-free) if the issue persists. Ask specifically whether there’s a known outage or maintenance window in your area. This is more common than people expect with a network that’s still actively expanding its 4G footprint.
Warning sign to watch for: If your data works fine on Wi-Fi but never connects on mobile data even after all the above, and this started suddenly without any settings change on your end, treat it as a possible network-side issue (tower maintenance, SIM registration problem) rather than something wrong with your APN. Confirm with customer care before spending more time tweaking settings.

Beyond the APN: Other Things That Actually Affect BSNL Internet Speed
People often assume APN tweaks alone can transform their internet speed. In reality, the APN gets you connected, but these other factors determine how fast that connection actually is:
- Network mode setting. Manually forcing “4G only” in a weak-coverage area can backfire by refusing to fall back to 3G/2G when 4G drops, leaving you with no connection at all instead of a slower one. Automatic mode is usually the safer choice unless you know your area has solid 4G coverage.
- VoLTE. If your phone supports it, enabling VoLTE (under Mobile Network settings) lets voice calls run over the 4G network instead of dropping down to 2G/3G, which otherwise interrupts your data session every time you take or make a call.
- Physical obstructions and location. Concrete walls, basements, and being far from a BSNL tower will throttle your speed regardless of how perfect your APN is. If you consistently get poor signal indoors, a mobile signal booster designed for Indian 4G bands can meaningfully improve in-home reception without needing a network upgrade.
- Background apps and data savers. Some battery-optimisation tools silently restrict background data for specific apps, which can look exactly like a network problem.
- Device and SIM slot. Older phones limited to single-SIM 4G (no simultaneous 4G on both SIMs) will quietly fall back to 3G/2G for your second SIM while the primary one uses 4G. Check which slot your BSNL SIM is in.
If you’re using a BSNL SIM inside a dongle or pocket router rather than a phone, the same bsnlnet APN applies, but device placement matters even more.
A dedicated 4G Wi-Fi router like TP-Link TL-MR100 [view on Amazon] can pull a noticeably stronger signal than a phone or basic dongle, especially in semi-rural areas where BSNL’s coverage is still expanding.
BSNL APN vs Other Operators (Quick Comparison)
If you’re switching SIMs or managing multiple connections, here’s how BSNL’s APN setup compares at a glance:
| Operator | Internet APN | Username/Password Needed | Notes |
|---|---|---|---|
| BSNL | bsnlnet | No | Same APN across most circles |
| Jio | Not required (auto-provisioned) | No | Jio uses a different provisioning method entirely |
| Airtel | airtelgprs.com or airtelhsdpa | No | Varies slightly by circle |
| Vi (Vodafone Idea) | www or vinternet | No | Auto-detected on most modern phones |

Myth vs Fact: BSNL APN Settings
| Myth | Fact |
|---|---|
| “Changing the APN type to ‘hipri’ guarantees faster speed.” | APN type tweaks can occasionally help on specific devices, but they don’t override actual network congestion or signal strength. Treat speed claims from forum tweaks with healthy scepticism. |
| “You need a different APN for 4G than for 3G.” | No; BSNL uses the same bsnlnet APN across 2G, 3G, and 4G data. |
| “A wrong APN can damage your phone.” | No. Changing APN settings is completely safe and reversible. Worst case, your data simply won’t work until you fix it. |
| “BSNL 5G will need a completely new SIM and APN.” | Based on how BSNL is upgrading its network, your existing SIM and the same APN are expected to continue working once 5G becomes available in your area. |
Expert Tips for Getting the Most Out of BSNL Internet
- Keep a screenshot or note of your original APN settings before making changes, so you can always revert if something goes wrong.
- If you frequently travel between circles, don’t worry about changing the MNC manually. Your SIM card itself carries circle-specific identification, and the network handles this in the background.
- For home use with a BSNL SIM in a router, place the device near a window facing the nearest mobile tower direction where possible; even an extra two signal bars can noticeably change your download speeds.
- If you manage BSNL connections for family members on older phones, write down the APN steps specific to their phone brand (Settings menus differ enough between Samsung, Xiaomi, and stock Android that “just go to Settings” often isn’t enough guidance for less tech-savvy users).

Conclusion
Getting your BSNL internet running fast really comes down to one thing: making sure the APN is set to bsnlnet, entered cleanly with no extra characters, and selected (not just saved) in your phone’s APN list.
From there, network mode, VoLTE, and your physical location do the rest of the work.
If you’ve gone through every step here and your data still isn’t working, the issue is more likely a network-side problem, congestion, a maintenance window, or a coverage gap in your specific area than anything wrong with your settings.
In that case, BSNL customer care (1503, toll-free) or the BSNL Selfcare app are your fastest paths to a fix.
Frequently Asked Questions
Configuring BSNL APN settings is necessary to guarantee that your device is correctly connected to the BSNL network and that your internet speed is optimised. By appropriately configuring the APN, you may enjoy quicker and more consistent internet browsing.
No, the APN settings on Android and iOS devices differ. To establish BSNL APN settings effectively, it is critical to follow the precise instructions provided in this article for your operating system.
If you are having trouble with your BSNL APN settings, make sure you have entered the right settings according to the instructions. If the problem persists, consider troubleshooting procedures such as rebooting your device, checking for software updates, or calling BSNL customer care.
Changing your BSNL APN settings is typically safe and poses no danger to your device or network. However, it is suggested that you save your original settings before making any changes so that you may restore them if necessary.
The correct APN is bsnlnet, typed in lowercase with no spaces. No username, password, or proxy is required.
Usually because the correct APN exists but isn’t selected, there’s a duplicate APN entry conflicting with it, the wrong SIM is set for mobile data on a dual-SIM phone, or there’s no active data pack on the account.
No. BSNL uses the same bsnlnet APN for 2G, 3G, and 4G data; there’s no separate “4G APN.”
Based on BSNL’s current network upgrade approach, the same bsnlnet APN is expected to continue working once 5G is available, since BSNL is upgrading existing 4G equipment rather than building an entirely separate 5G network.
Go to Settings → Network & Internet (or Connections) → Mobile Network → Access Point Names. The exact wording varies slightly by phone brand.
Go to Settings → Mobile Data → Mobile Data Network, and enter bsnlnet as the APN under the Mobile Data section. Leave the LTE section blank.
Yes, completely. Changing APN settings doesn’t damage your phone or SIM. At worst, incorrect settings simply mean mobile data won’t work until corrected.
It used to be bsnlmms with a separate MMSC URL, but since MMS server details vary by circle and have changed over time, it’s best to confirm the current value with BSNL customer care if you actually need MMS to work.
Many phones support 4G on only one SIM slot at a time. If your BSNL SIM is in the secondary slot, it may silently fall back to 3G/2G, or fail to connect to data at all depending on the device.
No. APN settings only control data/internet connectivity. Calls and SMS use a separate part of the network and will keep working even with a broken APN.
Insert your BSNL SIM, connect to the network, and accept the automatic APN configuration message BSNL sends. You can also try refreshing your network profile through the BSNL Selfcare app.
MCC (Mobile Country Code) identifies the country; 404 for India. MNC (Mobile Network Code) identifies the specific operator and circle; for BSNL, it varies by circle and is usually auto-filled by your SIM.
Check for duplicate APN entries, confirm BSNL is selected as the data SIM, verify your data pack is active (not just talktime balance), and restart your phone after any change.
It can occasionally help on certain devices by prioritising data traffic, but it won’t fix slow speeds caused by weak signal or network congestion. Those are the bigger factors in most cases.
As of mid-2026, BSNL has completed its nationwide 4G rollout and is working toward a 5G soft launch starting in Delhi, with broader expansion expected to follow gradually. Commercial 5G isn’t yet available across most of the country.
You can reach BSNL customer care at 1503 (toll-free) for APN, data, or general connectivity issues.
Yes, the same bsnlnet APN setting applies whether you’re using a phone, a USB dongle, or a 4G/5G Wi-Fi router with a BSNL SIM.
This is usually network congestion at peak usage hours (evenings especially) rather than an APN issue, since more users on the same tower share the same bandwidth.
Generally no, unless you’re certain your area has strong, consistent 4G coverage. Locking to 4G only in a weak-coverage area can cause your connection to drop out entirely instead of falling back gracefully to 3G or 2G.
No, the APN settings are identical for prepaid and postpaid BSNL connections. The difference is only in billing, not network configuration.
