What Is Honest Mobile?

Honest Mobile is a UK mobile network that launched in 2019 with one goal in mind: to do things differently. It runs on Three's network, which means you get solid 5G and 4G coverage across the UK. But what makes Honest Mobile stand out is its values: no mid-contract price hikes, loyalty discounts, and a strong commitment to the environment.

Honest Mobile was the first UK mobile network to become a B Corp, a certification given to companies that meet high social and environmental standards. It is also carbon-negative, meaning it removes more carbon than it creates, and donates 1% of its revenue to climate causes. So if being green matters to you, this network is worth a look.

Why Choose Honest Mobile SIM-Only Deals?

There are a few things that make Honest Mobile SIM-only deals different from the rest:

No Mid-Contract Price Rises

Unlike the big networks that often raise prices each year, Honest Mobile promises your bill will not go up while you are with them.

Loyalty Discounts

Your bill actually gets cheaper the longer you stay. You get a 5% discount every year, up to a maximum of 30%.

Month-by-Month Plans

All plans are on a rolling monthly basis, so there is no long-term commitment. You can cancel or change at any time.

Free EU Roaming

Every plan includes 5 free days of EU roaming per trip, so you can stay connected when travelling in Europe.

No Credit Check

Honest Mobile does not run a credit check, making it accessible to more people.

eSIM Support

You can order a physical SIM and swap it to an eSIM, giving you a faster and more flexible setup.

Honest Mobile SIM-Only Plans at a Glance

All Classic plans include unlimited UK calls and texts. Prices shown are approximate starting prices; your bill gets cheaper over time thanks to loyalty discounts.

Network Coverage: Powered by Three

Honest Mobile uses Three's network infrastructure, which covers 99% of the UK population outdoors and offers some of the fastest average 5G speeds in the country. Whether you are in a busy city or a smaller town, you should get reliable data speeds and call quality.

If you already use Three or a Three-powered network like iD Mobile or SMARTY, switching to Honest Mobile will give you the same signal, but with better pricing benefits over time.

How Does Honest Mobile Compare to Other Networks?

Switch makes it easy to compare Honest Mobile SIM-only deals alongside other UK networks. Here is a quick look at how it stacks up:

Feature	Honest Mobile	SMARTY	giffgaff
Powered By	Three	Three	O2
No Price Rises	Yes	Yes	No
Loyalty Discounts	Yes (5%/year)	No	No
EU Roaming	5 free days/trip	No	Selected plans

Unlimited Data From	~£25/mo	~£15/mo	~£20/mo

SMARTY offers cheaper unlimited data, but Honest Mobile wins on loyalty rewards and guaranteed price stability. For people who stay on the same plan for 2+ years, Honest Mobile often works out better value in the long run.

Who Are Honest Mobile SIM-Only Deals Good For?

Honest Mobile SIM-only deals work well for a range of people:

Light to moderate data users who need between 4GB and unlimited data per month

People who hate surprise price increases and want to know exactly what they pay each month

Long-term customers who want to be rewarded for staying loyal

Eco-conscious users who want their money to go to a carbon-negative company

Travellers who visit Europe regularly and want free roaming included

Anyone who does not want to pass a credit check to get a plan

Honest Mobile Smart SIM: What Is It?

In 2025, Honest Mobile launched a new product called the Smart SIM. This is an eSIM designed to work alongside your main SIM card. It connects to multiple UK networks, including EE, O2, and Three, and switches automatically to the best available signal.

The Smart SIM also includes unlimited data for over 200 essential apps and free global roaming in 180+ countries, making it useful for frequent travellers. Pricing starts at around £10 per month on a rolling contract or £45 for the full year.

This product is separate from the Classic SIM plans listed above and is aimed at people who want a backup connection or who travel internationally often.
