Mozillion vs EE: do you get the same network experience?

✔ Coverage is completely identical between the two

Mozillion are a budget provider that piggyback off EE’s network for signal. That means you’ll get identical 4G/5G data coverage on both providers (including band 20) as well as 2G call signal.

Well, EE have the largest 4G coverage of all UK networks. You’ll get 4G basically everywhere in built-up areas and in some surprisingly rural locations. You’ve got the best chance of staying on 4G on both.

You’ll also get 5G in these 1000+ UK towns and cities. And EE only claim a location once they cover 50% of its area, so coverage in these locations will be very widespread and you can get 5G in even more places.

Finally, 2G is also identical on both. But EE are replacing their 2G transmitters with 4G ones to improve coverage. That’s fine if your phone supports 4G calling, but if not you may have issues making calls.

✔ Data speeds are technically identical between the two

Mozillion don’t have any speed caps or built-in differences on their plans while EE actually do on most of theirs. That technically means that, on most plans, Mozillion offer faster data speeds than their hosts!

On both, we've had 4G speeds as high as 130+ Mbps in the city on EE’s full speed plans, while speeds went down to 5 Mbps in the countryside. Mostly we sat around 30-40 Mbps, which matches Opensignal’s result of 45.9 Mbps.

For 5G, Opensignal measured typical speeds of 96.8 Mbps while Speedtest got typical speeds of 114.39 Mbps with healthy peak speeds of 324.42 Mbps. That puts them both in joint third for 5G speeds of all networks.

Seeing as EE only offer full speed data on their higher end plans, you’re effectively paying more just to get the full network experience which is something Mozillion offer on all their plans as standard.

✔ WiFi calling is the same but EE have more features

WiFi calling and 4G calling let you make calls and send/receive SMS texts with WiFi and 4G signal rather than conventional 2G/3G call signal. These are essential now that old fashioned 2G/3G call signal is being removed.

Thankfully, both providers have it. In fact it seems that Mozillion have got their WiFi calling off-the-shelf from EE directly. From tests, we’re pretty sure their features are just the identical technology and will work on the same devices.

Both providers also let you join on an eSIM rather than taking a physical SIM card. But the process is more slick on EE as it took a few hours for our eSIM to work on Mozillion. Still, it’s something they both have.

Other than that, both support call forwarding. But only EE offer visual voicemail, which is expected as it’s mostly only the bigger networks that offer this. Still, it’s a pretty good showing from Mozillion.

✔ Inclusive EU roaming is only on Mozillion between them

EE removed inclusive EU roaming from most of their plans a while ago, while Mozillion include it on all their plans. That means you can only roam in the EU at no added cost on Mozillion between the two.

The amount of data you can use in the EU on Mozillion depends on your plan. On 1GB plans you can use 50% (500MB), on 3GB+ plans you can use 25% of your data and on unlimited data you can use 25GB.

That can be restrictive on smaller data plans, but on larger data plans you can use quite a lot of data before you run out. For short trips we think few people will hit their limit, so it’s a good scheme overall.

EE only include EU roaming on their expensive premium plans, or else you’ll pay per day. You do get inclusive roaming outside the EU on their most expensive Full Works plans, but for us EU roaming is more important.

✔ Mozillion have no credit checks on their plans

One big advantage Mozillion have over EE is that you can join any of their great value 12 or 24-month contracts without passing a credit check. That makes them an excellent choice if you’ve been rejected by EE.

Mozillion also have a range of great value 1-month plans with no contracts. These let you switch plans month to month or leave Mozillion altogether for any reason. EE have some too but they’re very expensive.

You also can’t accidentally overspend on extras on Mozillion as you can only use what’s included in your plan. But we’re not sure you can even top up to use extras, which is a bit frustrating.

In all, the way Mozillion structure their plans is their main benefit. They’re a great choice if you don’t have the best credit history or just want a flexible plan without paying a massive amount like on EE.

✔ EE offer a good amount of extra benefits

If you’ve got family members or close friends that want to join on a plan, you may like EE’s family plan scheme. This gives you a generous 30% off extra plans on your account and lets gift data between users.

And you’ll even get a 1GB data boost on your plan for every user you add to your account. You can then gift that data to help prevent users for hitting their data limit.

EE also let you continue using data even when you’ve used up your allowance with their stay connected data. This helps you avoid extra data charges, but speeds will be restricted to 0.5 Mbps for this.

Finally, EE offer some nice benefits on their premium plans. These include things like a subscription to one of these entertainment services or these music streaming services, on top of things like EU roaming.

✔ EE offer more flexible phone contracts at higher prices

You can take a phone contract from both EE and Mozillion. But Mozillion offer theirs on more traditional 24-month contracts where you pay for your phone and usage plan (mins, texts, data) as one bill.

But EE split your bill into one credit agreement (basically a loan) for your phone and a separate one for your usage plan. This gives you the freedom to pay off the cost of your phone to upgrade whenever.

You also get the choice of a 24 or 36-month contract to suit your budget. The downside is that it will be harder to pass a credit check for these as EE have to be sure you can afford to pay them back.

Mozillion do tend to offer lower prices on their phone contracts, however. And these won’t go up in price at all, while EE’s usage plans will. So it’s a trade off of lower prices for less flexibility on Mozillion.
