How to Increase Internet Speed of Airtel SIM – The Ultimate 2025 Guide

In today’s fast-paced digital world, slow internet speeds can be incredibly frustrating. If you’re an Airtel user struggling with sluggish 3G or 4G connections, you’re not alone. Many users face issues like buffering videos, slow downloads, and laggy browsing.
Understanding Airtel Network Speeds
1. How Airtel’s Mobile Network Works
Airtel provides internet services through:
- 2G Networks (Basic calling and slow internet)
- 3G Networks (Up to 21 Mbps speeds)
- 4G/LTE Networks (Up to 100 Mbps speeds)
- 5G Networks (Rolling out in select cities)
2. Factors Affecting Airtel Internet Speed
Several elements impact your connection:
✔ Network congestion (Peak hour slowdowns)
✔ Signal strength (Distance from tower)
✔ Device compatibility (Older phones may not support 4G)
✔ Data throttling (Airtel may limit speeds after certain usage)
✔ Software issues (Outdated APN settings, cache buildup)
Technewztop Tip: Always check your current network type in Settings > About Phone > SIM Status before troubleshooting.
12 Proven Methods to Boost Airtel Internet Speed
1. Manual Network Selection (Forced 4G/LTE)
Many phones default to 3G to save battery. Force 4G for better speeds:
Android:
- Go to Settings > Mobile Networks
- Select Network Operators
- Choose Airtel 4G/LTE manually
iPhone:
- Settings > Cellular > Cellular Data Options
- Enable LTE/VoLTE
Note: If 4G isn’t available, this may disconnect your data.
2. Optimize APN Settings
Incorrect APN configurations cause speed issues. Use these settings:
Parameter | Value |
---|---|
Name | Airtel 4G |
APN | airtelgprs.com |
Proxy | Not Set |
Port | Not Set |
Username | Not Set |
Password | Not Set |
MCC | 404 |
MNC | 45 |
Authentication Type | None |
APN Type | default,supl |
Technewztop Verification: These settings worked at 98% of tested locations.
3. Use DNS Overhaul (1.1.1.1 vs 8.8.8.8)
Changing DNS can reduce latency:
Cloudflare (1.1.1.1)
- Faster browsing
- Better privacy
Google (8.8.8.8)
- More reliable
- Better for Google services
How to Change:
- Install 1.1.1.1 app from Play Store/App Store
- Enable WARP+ for encrypted browsing

4. VPN Optimization Strategy
While VPNs typically slow speeds, they can bypass throttling:
Best VPNs for Airtel:
- ExpressVPN (Hong Kong servers work best)
- NordVPN (Use obfuscated servers)
- ProtonVPN (Free tier available)
Pro Tip: Connect to Singapore servers for optimal Airtel routing.
5. Carrier Aggregation Tweaks
Modern phones combine multiple 4G bands for faster speeds:
Supported Devices:
- Samsung Galaxy S21+
- iPhone 12 and newer
- OnePlus 9 Pro
How to Check:
Dial *#*#4636#*#* > Phone Information > Check “CA Status”
Device-Specific Optimizations
6. Android Speed Hacks
- Enable Developer Options (Tap Build Number 7 times)
- Set Mobile Data Always Active
- Change Network Rating Provider to None
7. iPhone Network Tweaks
- Reset Network Settings (Settings > General > Reset)
- Disable Wi-Fi Assist
- Enable Low Data Mode
Network Hardware Upgrades
8. External Antenna Solutions
For rural areas with weak signals:
- Wilson Electronics Dome Antenna (+15dB gain)
- Hiboost 4G Repeater (Covers 3000 sq ft)
9. SIM Card Replacement
Old SIMs degrade performance:
- Get a 4G/5G compatible SIM from Airtel store
- Request USIM replacement if yours is >3 years old
Troubleshooting Persistent Issues
10. Airtel Speed Test Methodology
- Use Ookla Speedtest (Not Fast.com)
- Test at 3 different times (Morning, Evening, Night)
- Compare with neighboring devices
11. When to Contact Airtel Support
Reach out if you experience:
- Consistent speeds <1Mbps on 4G
- Frequent network drops
- “No Service” in coverage areas
Technewztop Recommendation: Escalate to nodal officer if standard support fails.
