What is Honest Mobile?

Honest Mobile is a new mobile virtual network provider operating in the UK. The network is using Three’s network to provide 5G, 4G, and 3G coverage, however, they’re not owned by the Three Network.

The carrier also rewards its loyal customers by reducing their bills each month by up to 30%. Thanks to Honest Mobile’s loyalty discount your bills will get cheaper each month you remain a customer. The network also has an app, which you’ll need if you want to use their WiFi Calling feature. The app is also useful if you’re looking to switch between plans, just click on the app and choose your new tariff, it will take effect the next day.

Honest Mobile offers 30-day and 12-month pay monthly plans to choose from. Honest Mobile plans come with unlimited UK calls and texts. Their deals also include free 5G, WiFi Calling, and free EU roaming. Their customer support is quite responsive, and they claim they’ll return to you within 30 seconds online. Honest Mobile’s 30-day deals are commitment-free, meaning there are no credit checks to pass.

Honest Mobile is also the UK’s first carbon-neutral mobile network, meaning they offset all emissions associated with mobile usage (be it making calls, sending texts, or using data), including the running of their HQ. They even plant trees on your behalf and you can track how many trees have been planted under your name!

Network Coverage & Speeds

Honest Mobile 4G Coverage

Honest Mobile uses Three as its main network provider, this means the network doesn’t support 2G, and if you have a 2G only device, an Honest Mobile SIM won’t work with your phone.

Honest Mobile offers over 99% population coverage, but what matters the most is geographical coverage, and Honest Mobile’s provider Three ranks as the worst in terms of 4G coverage in the UK.

As always, we strongly recommend you use the network’s coverage map before you sign a contract with them. If their coverage is weak in your frequent areas, then your mobile experience will be poor

Honest Mobile 4G Speeds

Your data speeds will vary, but looking at Opensignal’s latest network test results, we see that Three’s average 4G download speeds are around 25Mbps, and its upload speed is around 6.3Mbps. Honest Mobile itself wasn’t tested, but the result would be identical.

Please, keep in mind that your experience may greatly differ due to a number of reasons. Even the time of the day can drastically affect the data speeds you can get.

Honest Mobile 5G Coverage

Honest Mobile offers 5G at no extra cost to all their customers, regardless of their choice of SIM tariffs. Honest Mobile 5G piggybacks on Three as well, meaning it is available in over 300 locations covering more than 29% of the UK’s landmass,

In order to get 5G coverage from Honest Mobile, you’ll need to be in an area with Honest 5G, and you’ll need a 5G smartphone, or else you can’t enjoy superfast download and upload speeds.

Honest Mobile 5G Speeds

According to Opensignal’s latest 5G test results, Honest Mobile’s average 5G download speeds are around 105Mbps, and their 5G upload speeds average around 11.6Mbps.

Both Opensignal and OOKLA say Three (Honest’s provider) offers the fastest average 5G download speeds alongside EE in the UK. Having said that, even the slowest 5G data speeds are more than enough to stream 4K videos, and other heavy data activities without any issues, it’s hard to go wrong with a 5G network at the moment, if they offer coverage in your area.

WiFi Calling and 4G Calling

4G Calling (a.k.a. VoLTE) allows you to make and receive calls over your mobile provider’s 4G network. It’s like making a regular phone call, but your handset uses 4G instead of 2G or 3G. Thanks to 4G Calling your calls are clearer & connect faster. Plus when you’re on a call, you’ll stay connected to 4G. This feature also eliminates many indoor blackspots so you can stay connected in more places.

WiFi Calling keeps your device connected by using an available WiFi connection. Your device will stay connected even when you’re not getting any regular phone signal.

Honest Mobile offers WiFi Calling support through their mobile application, but sadly, 4G Calling (VoLTE) isn’t yet available. To benefit from Honest Mobile’s Wi-Fi Calling you’ll need a compatible device and the Honest Mobile App.

If you want both 4G Calling & WiFi Calling, we recommend iD Mobile. Make sure to read our iD Mobile Review to discover all you need to know about their deals and coverage.

Personal Hotspot

Turning your smartphone into a personal hotspot means you can share your mobile data with other people, or to be more specific with other compatible devices such as laptops, tablets, and other smartphones. All you have to do is turn your Wi-Fi Hotspot on and Honest Mobile allows you to tether freely, with no restrictions whatsoever.

As always, we’d like to remind you that you should always stay on top of your usage when tethering as you can burn through your mobile data at a much faster rate. We suggest having a large data plan or even an unlimited data plan if you’re considering tethering to other devices on a regular basis. While Honest 5G is great for streaming shows and movies, their 4G isn’t really that reliable.


Honest Mobile puts each country into a roaming zone: EU Roaming Zone, Zone 1, Zone 2, and Zone 3.

The network lets you use your UK minutes, texts, and data in 43 destinations in the EU Zone. If you ever go over your UK allowances while in one of these countries, you won’t pay more than what you would pay back at home. You can find how much you’d end up paying in other zones besides the EU Zone by checking the Honest Mobile website.

Honest Mobile will only let you use a maximum of 20GB of data when roaming abroad. The network also limits free international roaming to a maximum of 2 months. After the two-month period surcharges will apply.

Honest Mobile’s Features

Loyalty Discount

The carrier rewards loyalty with increasing monthly discounts. The Loyalty Discount increases by 5% each month and it’s capped at 30%. These discounts don’t apply to bolt-ons and additional charges though. Honest Mobile also offers a 10% discount when you purchase an annual membership, but sadly these two discounts can’t be combined together.

No Credit Checks

Honest Mobile’s deals work on a prepaid basis, meaning they don’t require a credit check. You just pay for your tariff and you’re good to go.

Family/Group Plans

You can add as many SIMs as you want to your Honest Mobile account, which is great for families. However, there are no major benefits or discounts offered by the network, except data sharing across multiple SIMs. You can read our Best Family Mobile Plans guide to find out the best deal for your loved ones.

Carbon Neutral

Honest Mobile is the UK’s first carbon-neutral mobile network, meaning they offset all emissions associated with making calls, sending text messages, or using data. They also do the same for running their HQ. On top of that, 1% of Honest Mobile’s revenue goes towards reforesting the world. Their Honest Mobile App even lets you track how many trees have been planted under your name.

Half Cooked’s Overall Breakdown

Honest Mobile is a decent choice, especially if you want to reduce your carbon footprint. The network offers some decent features, plus you get 5G at no additional cost. However, their WiFi Calling is not as great as most other networks and 4G Calling isn’t included.

While their 30-day SIM only plans don’t require credit checks, the prices are noticeably higher than some of the other MVNOs. They don’t offer a wide variety of SIM-only deals either, meaning you have limited options.

With everything combined, Honest Mobile deserves four stars out of five, but mainly because they’re an eco-friendly network and they’re the only UK network doing it right.
