In today’s digital world, fast internet is not a luxury—it’s a necessity. Whether you’re streaming, downloading, working remotely, gaming online, browsing social media, or attending online classes, slow internet can be extremely frustrating.
Many people think slow internet is only caused by their mobile network provider. But in reality, the problem is often from:
✔ Wrong phone settings
✔ Incorrect APN configuration
✔ Low signal strength
✔ Outdated SIM card
✔ Background apps consuming data
✔ Network congestion
✔ Browser issues
✔ Weak device performance
The good news is:
There are many easy and effective ways to boost your 4G or 5G mobile internet speed instantly—without cheating or illegal tricks.
This article provides the most complete and updated 2025 guide to increasing mobile internet speed on Android and iPhone.
Let’s begin.
1. Switch Your Network Mode to 4G or 5G (Most Important Step)
Many phones automatically fall back to 2G or 3G when network conditions fluctuate.
This drastically reduces speed.
✔ Here’s how to fix it:
Android:
Settings → Network & Internet → Mobile Network → Preferred Network Type → Select 4G/5G
iPhone:
Settings → Mobile Data → Voice & Data → Select 4G or 5G Auto
✔ Why this helps:
4G is 10x faster than 3G
5G is up to 20x faster than 4G
If your phone supports 5G but your SIM or area doesn’t, your device may struggle to maintain stable speed. Always choose the highest network mode available.
2. Check if Your SIM Card Supports 4G/5G
Some old SIM cards only support 2G or 3G.
Signs your SIM card is outdated:
❌ 4G option does not appear in settings
❌ Phone stays on 3G even in strong 4G areas
❌ Slow browsing despite full bars
Solution:
Visit your network provider and upgrade your SIM to 4G or 5G ready.
This alone can increase your browsing and download speeds dramatically.
3. Put Your SIM in the Correct Slot
Most Android phones only support 4G/5G in SIM Slot 1.
If your data SIM is in slot 2, you will get slower speeds.
✔ Solution:
Move your internet SIM to SIM Slot 1.
A simple but powerful fix many people ignore.
4. Use the Correct APN Settings (APN Fix)
Incorrect APN (Access Point Name) settings reduce speed drastically.
Below are the correct APN settings for Nigerian networks:
✔ MTN Nigeria
Name: MTN
APN: web.mtnnigeria.net
✔ Airtel Nigeria
Name: Airtel
APN: internet.ng.airtel.com
✔ Glo Nigeria
Name: Glo
APN: gloflat
✔ 9mobile
Name: 9mobile
APN: 9mobile
After entering the APN:
✔ Save
✔ Restart phone
Your internet should become faster and more stable.
5. Reset Network Settings (Fix Hidden Problems)
This is one of the BEST fixes for:
✔ Slow browsing
✔ Network drops
✔ YouTube buffering
✔ Apps not loading
✔ Incorrect network configuration
✔ Android:
Settings → System → Reset → Reset WiFi, Mobile & Bluetooth
✔ iPhone:
Settings → General → Reset → Reset Network Settings
This restores your phone’s networking system to factory default—solving up to 70% of internet issues.
6. Turn Airplane Mode ON and OFF
This forces your phone to reconnect to the:
✔ Nearest
✔ Strongest
✔ Fastest
network tower.
Steps:
Turn ON Airplane Mode → Wait 5 seconds → Turn OFF
Your network will refresh and often become faster.
7. Disable Battery Saver Mode
Battery saver slows down internet speed to reduce power usage.
When battery saver is ON, apps load slower and browsing becomes unstable.
✔ Turn it OFF:
Android: Settings → Battery → Battery Saver → OFF
iPhone: Settings → Battery → Low Power Mode → OFF
8. Turn Off Background Apps Consuming Data
Apps running in the background steal your bandwidth.
Top offenders:
- Snapchat
- TikTok
- Play Store auto-updates
- Cloud backups
✔ Disable background data:
Settings → Apps → Data Usage → Disable Background Data
This instantly boosts your browsing speed.
9. Clear Browser Cache and Cookies
Browsers accumulate junk files that slow loading speeds.
✔ Chrome:
Settings → Privacy → Clear Browsing Data → Cached Files
✔ Safari (iPhone):
Settings → Safari → Clear History & Website Data
Clearing cache improves speed and frees storage.
10. Use a Fast Browser Designed for Speed
Not all browsers perform the same.
🚀 Fastest Browsers for 2025:
✔ Chrome
✔ Opera Mini
✔ Brave
✔ Samsung Internet
✔ Firefox
Opera Mini is best for slow networks because it compresses data.
11. Turn Off Auto-Download in Social Media Apps
Auto-download slows your internet and consumes data.
Disable auto-download:
WhatsApp:
Settings → Storage → Media Auto-download → OFF
Telegram:
Settings → Data & Storage → Auto Download → OFF
Facebook & Instagram:
Disable HD auto-play.
This frees bandwidth for faster browsing.
12. Use Data Saver Mode (Optional)
Data saver reduces page size and loads sites faster.
✔ On Chrome:
Settings → Lite Mode (if available)
✔ On Android:
Settings → Network → Data Saver → ON
Useful in areas with weak signal.
13. Restart Your Phone Regularly
Restarting refreshes:
✔ RAM
✔ System processes
✔ Network drivers
✔ Background apps
This improves both phone and internet speed.
14. Check for System Updates
Phone manufacturers release updates to improve:
✔ Network performance
✔ Signal handling
✔ Bug fixes
Always update to the latest software.
15. Update Your Apps
Outdated apps slow down performance and browsing speed.
Open Play Store → Manage Apps → Update All
16. Remove and Reinsert SIM Card
A loose or dusty SIM card can cause:
❌ Slow speed
❌ Poor signal
❌ No 4G/5G
Clean the SIM gently and reinsert it.
17. Move to a Location With Better Signal
Your environment affects speed.
Best spots:
✔ Near windows
✔ Open areas
✔ Outdoors
✔ Upstairs floors
Avoid:
❌ Basements
❌ Thick-walled rooms
❌ Crowded areas (network congestion)
18. Keep Your Phone Cool
Overheating slows the processor and internet.
Avoid:
❌ Playing heavy games while browsing
❌ Charging while streaming
❌ Using phone in direct sunlight
A cool phone performs faster.
19. Use WiFi Assist / Dual Channel Acceleration
Some phones support “dual acceleration,” which combines WiFi + mobile data for faster speed.
Settings → Connections → Dual Channel Acceleration
This improves video streaming and downloading.
20. Limit Hotspot Users
Sharing your hotspot divides your bandwidth.
Disconnect unwanted users for faster browsing.
21. Disable VPN or Proxy (Unless Premium)
Free VPNs reduce internet speed by 50–90%.
If browsing is slow:
✔ Turn OFF VPN
✔ Use only premium servers if needed
22. Switch to a Less Congested Band
Some networks allow switching between:
✔ 4G LTE Band 3
✔ 4G LTE Band 7
✔ 4G LTE Band 20
✔ 4G LTE Band 28
A less congested band = faster internet.
23. Use an External 4G/5G Router (Advanced Option)
Routers have stronger antennas and connect to faster frequencies.
You can then connect your phone via WiFi.
This is very helpful in rural or weak-signal areas.
24. Contact Your Network Provider
Sometimes the issue is NOT your phone.
Call customer care and report:
✔ Slow browsing
✔ Poor signal
✔ Network congestion
They can refresh your connection or provide coverage updates.
25. Change Your Network Provider (Final Option)
If one network is consistently slow in your area, switch to a stronger alternative.
Some networks are better depending on your location.
Why Mobile Internet Becomes Slow (Common Reasons)
✔ Poor signal
✔ Network congestion
✔ Wrong APN settings
✔ Old SIM card
✔ Too many background apps
✔ Weak phone hardware
✔ VPN slowing down
✔ Outdated software
✔ Browser cache overload
✔ Fair usage policy active
Knowing the cause helps you fix the issue faster.
