What is a 4G Super-Voice compatible phone?

A 4G Super-Voice compatible handset is one that Three has made compatible with the technology.

As long as your phone supports 4G and has a Three SIM card in it it’s likely that it could theoretically support 4G Super-Voice, but right now the list of 4G Super-Voice compatible phones includes: iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone XS, iPhone XS Max, iPhone XR, iPhone X, iPhone 8, iPhone 7, iPhone 7 Plus, iPhone 6, iPhone 6 Plus, iPhone 6S, iPhone 6S Plus, iPhone SE,  Samsung Galaxy S10, Samsung Galaxy S9, Samsung Galaxy S8, Samsung Galaxy S8 Plus and many more. Check if your phone is compatible

However, if you’re using an Android or Windows handset it must have been bought from Three to be compatible (though this may change in the future). iPhones are exempt from this, so your iPhone can have been bought anywhere as long as you’re now using it on the Three network.

Check if your phone is compatible with 4G Super-Voice

Any phone you buy from this page will be compatible with 4G Super-Voice. If you already have a handset it needs to be one of the ones from the list above and needs to have come from Three (unless it’s an iPhone). It also, of course, needs to be on the Three network/using a Three SIM card.

Three has said it’s aiming to ultimately make Android and Windows handsets that weren’t bought directly from the network compatible with 4G Super-Voice too, but hasn’t done so yet.

How do I activate 4G Super-Voice?

Once you’re sure you have a 4G Super-Voice compatible phone you simply need to make sure it’s running the latest software to work with 4G Super-Voice. There’s a good chance 4G Super-Voice is already active, but to be sure head here to download the latest software for your handset.

Once done, 4G Super-Voice should work automatically when in an area with 4G Super-Voice coverage. There’s no app and no settings you need to toggle (aside from ensuring mobile data is turned on).

Are you in a 4G Super-Voice coverage area?

Three coverage checker

4G Super-Voice is available in many of the same places as standard 4G, including most cities and large towns.

To know whether Three has 4G Super-Voice coverage in your area, head to the network’s coverage checker and enter your handset and location.

If not, don’t worry, as Three’s 4G Super-Voice coverage is increasing all the time, so it might arrive where you are soon.

Benefits of 4G Super-Voice compatible phones

If your phone is 4G Super-Voice compatible that means you’ll be able to make and receive calls over 4G. That’s good for a number of reasons, but most notably because it means you’ll have coverage in places you never used to (as there will be areas that have 4G coverage but not 3G or 2G).

That will be especially useful for rural areas and indoor blackspots, and 4G Super-Voice will also boost signal in areas where there already was some. So, if you previously had poor signal (potentially leading to crackly or dropped calls) it might now be strong.

Other benefits of 4G Super-Voice include superior voice quality so calls are clearer. Calls should connect fast too over 4G Super-Voice, since 4G itself can carry data faster, and you might even see a slight boost in your battery life.

Best of all, 4G Super-Voice is seamless – there’s no separate app and you can keep using your normal Three number.


Does 4G Super-Voice cost anything?

No. 4G Super-Voice comes at no extra cost on Three.

How will I know when 4G Super-Voice comes to my area?

If you’re already a Three customer then the network will send you a notification when 4G Super-Voice is available in your area. You can also use Three’s coverage checker to check for yourself.

How will I know if 4G Super-Voice is working?

Since 4G Super-Voice is essentially 4G calling you should see a 4G symbol in your status bar when on the phone. You may also have an idea that it’s working because there will be coverage where there wasn’t before, or your signal will be stronger.

Is 4G Super-Voice available on all Three plans?

Yes. Whether on Pay Monthly, SIM Only or Pay As You Go, and whether you have an Essential Plan or an Advanced Plan you should be able to get 4G Super-Voice on compatible phones.

Is there any downside to using 4G Super-Voice?

No. It’s just one more great bonus to being on Three.

My phone isn’t compatible with 4G Super-Voice, will it ever be?

Quite possibly. Three is adding to the list of compatible phones all the time, so yours might be added one day assuming it supports 4G. The newer and more popular your handset is the more likely it is to be supported in future.
