How to Increase SMART Internet Speed

SMART is a 4G telecommunication network in Belize that provides mobile phone, calling, internet, and value-added services. If you have a SMART SIM and you are using the internet on your mobile phone or any device, then this post can help you a lot. Sometimes, when we use the internet on a SMART SIM using 3G or 4G, the internet speed goes down. We receive under 100 kbps of internet speed on our SMART 4G SIM.

There are many reasons for slow internet speed, including location, time of day, network signals, and 3G or 4G coverage. The most famous telecom network in Belize, SMART, has 10 Mbps for download and 10 Mbps for upload. So, we will know why SMART’s internet speed is down and how to increase SMART’s internet speed in Belize.

What is Actual SMART Internet Speed?

Internet speed depends on different factors, like location, network signals, and device compatibility. Here are the details of SMART’s real internet speed, which was tested on different sources.

How to Increase SMART Internet Speed: Tips for improving your SMART 4G internet connection

Here are some tips to increase SMART’s internet speed, which will help you have faster internet.

1. Change your DNS settings

You can change your mobile phone’s DNS settings to Google’s public DNS servers, which can increase SMART’s internet speed. DNS can help you browse the web and increase internet speed using cloud servers.

Add the following DNS in your network APN settings:




  • 2001:4860:4860::8888
  • 2001:4860:4860::8844

2. Check the Signal Strength and Area

You can check the signal strength in the status bar of your phone. Connect to the strongest possible SMART 4G signal if signals are weak. You can also check internet coverage by dialing *147#.

Many people use mobile phones in closed places like basements, elevators, or any closed room. Avoid using your phone in such areas and use the mobile phone in an open place where full signals from the SMART 4G network are received.

3. Connect to 4G LTE (Not Auto)

Connecting to only 4G LTE mode can resolve your issue, but sometimes not. If you are in good coverage, set up only 4G LTE mode in your mobile phone network settings. By doing this, you will receive only SMART 4G signals, not others, and it will help you improve the internet.

4. Restarting your phone can resolve the issue

Restart your mobile phone or SMART 4G device (if you have one) to improve the internet speed. Many times, internet caches and cookies are saved on our phones, which causes slow internet. You can also activate airplane mode and then deactivate it in a few seconds to resolve the issue.

5. Use the High-Speed Internet Package and Plans

I have seen this problem in many places, and it has been my personal experience that if you are using free internet on a SMART sim, it slows down. First of all, you need to check that you have an internet package or offer active on SMART SIM. If your internet offer has expired, you will need to renew it.

Like many other companies, SMART also offers unlimited internet to its customers, but its speed is slower than 64 kbps. This leads to a bottleneck on the internet. You can activate premium internet by dialing 1090 or *123# from your mobile phone. Here are some plans that you can activate and check the internet speed.

6. Check the SMART APN Settings

Check the APN settings on your mobile phone to see if they are correct or not. Install and activate a new APN profile using the settings.

SMART APN for the Internet:

Open the mobile phone settings and follow the prompts: Go to Settings > Mobile network > Access Point Names > Tap the + button to create a new APN and enter the APN settings.

  • APN Name: SMART Internet
  • APN: Internet
  • Port: (empty)
  • Username: SMART
  • Password: SMART
  • Authentication type: None
  • APN protocol: IPv4

  • Username: (leave blank)
  • Password: (leave blank)
  • APN Type: default
  • Proxy: (leave blank)
  • Port: (leave blank)

7. Change Internet Usage Time

SMART is the most used internet provider in Belize, which is due to its cheapest plans. When people come home from offices and shops, they use the internet at home. In these cases, the SMART server slows down due to high traffic, and SMART users face slow internet issues. You can use these tips to resolve the issue:

  • The best time to use the internet on SMART at high speed is typically during late-night hours, such as between 11 pm and 5 am
  • Don’t use the internet between 5 PM and 10 PM for downloading because the traffic can be high at this time and you can face slow internet settings.

8. Disable any unnecessary apps

Disable any unnecessary apps that are running in the background. These apps can use up bandwidth and slow down your internet connection. Most of the time, this problem occurs on Android phones due to more apps downloaded and internet usage. You can delete redundant apps and block them from network access by going to your mobile settings.

Troubleshooting SMART 4G internet speed issues

  • Check the SMART 4G signals
  • See the internet speed through any internet speed test tool like Ookla
  • Clear the cache and cookies of your browser
  • Check the SMART internet package or plan usage
  • Restart your mobile phone or SMART device if have
  • Call the SMART helpline 1090


Jaz is one of the best telecom networks in Belize and is present in almost every region. Its 4G signals may not be available in some areas, such as rural and forested areas.

You can also check SMART’s coverage on their official website and talk to their call center representative. If you face an internet connection problem on SMART SIM, please confirm that your internet plan is active.
