How to speed up your slow mobile internet in 9 ways

Whether your phone is downloading too slowly or you are just looking for a quick connection for everyday activities, there are several ways you can improve your mobile data speed. Follow these steps to get a better data connection.

  1. Hold down your power button and slide the power icon on the screen to turn the phone off
  2. Hold the power button to turn the phone back on

Check your data usage limit

Your phone plan may have a data cap, so it’s a good idea to check your limit. Often, even if you have an unlimited data plan, your data has a limit beyond which the speed will slow down. Check with your mobile data provider if you’re unsure what your limit is.  


If you have reached your limit, you may have to wait for the start of the next billing cycle for your data to speed back up. During this time, opt to use Wi-Fi connections for quicker internet speeds.  


Follow the steps below to check how much data you have used on iOS or Android.


For iOS:

  1. Go to Settings > Mobile Data or Settings > Cellular
  2. Under Current Period it will show you how much data you have used
  3. Below that, you can see how much data the systems and apps on your phone are using

For Android:  

  1. Go to Settings > Network & Internet
Android Settings

2. Tap Internet

Move to a new location

Sometimes the fix is as simple as moving to a different location. Your service may not be amazing at your current spot, so moving to an area with a better service connection can help speed your internet up.  

Check if you are using a VPN

Are you using a Virtual Private Network (VPN)? VPNs are great tools to use to connect to the internet securely. Still, sometimes this can slow down your internet speed or even block internet traffic altogether, depending on the settings for your specific VPN.  


Disconnect your VPN to see if that increases your internet speed.  

Reset your network settings

Misconfigured network settings can slow down your phone’s data speed. Apps can disrupt your network settings as well without your ever knowing it. Reset your network settings to see if this helps.  


How to reset network settings on iOS:

  2. Tap Reset Network Settings
