Normally, when you join SMARTY, all your settings will update automatically and everything should work fine. 

However, if you can’t access the internet when you’ve got available data (yet you can still make calls), let’s check your Access Point Name (APN) settings.

In all likelihood, you’ll need to replace your current APN settings with SMARTY’s details.

This article reveals how to find your APN settings and tells you what to enter. Please ensure that you read this guide in full because, if you’ve got an iPhone, there’s an extra step to complete.

Also, if you’re using an iPhone or a Sony Xperia device, then you’ll need to enter different details. We’ve listed these settings below, too. 

Here’s how to find your APN settings:

  • On Android: Settings > More… (under Wireless & Networks) > Mobile Network > Access Point Names > 3 > Edit Access Point
  • On iOS: Settings > Mobile > Mobile Data Options > Mobile Data Network

Found your APN details?

Next, replace what’s there with the information below. Remember, if you’ve got a Sony Xperia device, you'll need to follow the link below.

An additional step for iPhone users

If you’ve got an iPhone, you will also need to change the 4G settings so that it reads ‘Data only’ instead of ‘Voice and data’.
