My new work route has so many blackout spots... Smart SIM fixes that. It's been a no-brainer lifesaver and can only get better. I couldn't recommend enough!

I was right out in the sticks, my network had lost all bars and I was lost. So I switched to my Smart SIM and boom! Enough service to get maps to show me the right direction. I truly do thank my Smart SIM for saving me!

As soon as I turned off airplane mode, Smart SIM kicked in and I had maps, messages, and data in seconds. I found my route, messaged the hostel, and got there without stress. I couldn't believe how easy and reliable it was. Total lifesaver.

“Smart SIM is a game changer and incredibly good value.”

Josh - Honest Customer

How is Smart SIM so affordable?
Unlike other multi-network SIMs, Smart SIM is just for your essential apps (including WhatsApp, Maps, ChatGPT, and hundreds more). So you have peace of mind about staying connected, without the sky-high costs.

Use your main SIM for

  • Social Media
  • Open web browsing
  • Video calls
  • Regular calls (WhatsApp calls available on Smart SIM)

We were fed up with rubbish signal and expensive roaming. So we built Smart SIM.

It works alongside your main SIM to give you 500+ apps on EE, O2, Three and Vodafone, plus free global roaming.

So you have peace of mind about staying connected, without worrying about unreliable signal, dodgy wifi or sky-high bills.

More than 43,000 happy customers have already joined us. We'd love to welcome you onboard too.

Unlike the big networks, we believe it's time for change.

It's time for mobile done right.

Straight from our team of (extremely friendly) experts

Smart SIM is the ultimate back-up eSIM. It's a data-only eSIM that works alongside your main SIM to give you:

📶 Unbeatable UK signal – 500+ apps on EE, O2, Three and Vodafone

🌎 Free global roaming – 500+ apps with unlimited data in 180+ countries

So whether you’re deep in the countryside, mid-commute, or holidaying in Cameroon, Smart SIM keeps you connected when it matters most.

Set up once then switch in a few taps whenever you lose signal or go abroad. No more rubbish signal, relying on wifi or expensive roaming fees 👋

Easy. Switch to Smart SIM in just a few taps or wait for it to kick in when your main SIM completely loses signal.

Good question. We’ve always done things differently at Honest in our mission to build the best mobile network on the planet.

After introducing Classic SIM to thousands of happy customers, we knew people everywhere still faced two big problems: rubbish signal and expensive roaming. So we built Smart SIM.

All the most essential ones: WhatsApp, Google Maps, Uber, Citymapper, Monzo… the list goes on. Check out the 500+ apps on Smart SIM here.

Smart SIM is £10/month on our 30-day plan, or £45 for the year if you choose our annual plan (that’s just £3.75/month 😮).

We wouldn’t recommend it. You'll need your main SIM for calls and texts, social media and streaming, and open web browsing.

Smart SIM works alongside your main SIM, ready for you to switch to whenever you lose signal or go abroad. Think of it as your trusty back-up, there when you need it most.

It sure is. Consider it the all-you-can-eat buffet for apps including WhatsApp, Google Maps, Uber, Monzo and many more 📱

You can WhatsApp call and message, but if you're going old school, you'll need your main SIM for texts and calls.

Smart SIM is eSIM only, so you can add it to your phone and start using alongside your main SIM right away.

Just check your phone is eSIM compatible before ordering.

We thought you’d never ask 🤩 Click here to get your Smart SIM – you’ll be up and running quicker than you can say ‘unbeatable signal and free global roaming’.

Smart SIM is the ultimate back-up eSIM. It works alongside your main SIM (on any network) to give you 500+ apps on EE, O2, Three and Vodafone, plus free global roaming in 180+ countries around the world. So you never have to worry about rubbish signal or expensive roaming again.

Classic SIM, on the other hand, is your essential everyday UK SIM for texts, calls and data. It piggybacks on VodafoneThree to give you the UK's fastest 5G. For the ultimate peace of mind when it comes to your signal, we recommend using both.

Not yet. Smart SIM doesn’t support VPNs right now, but we’re working hard on new features. Watch this space 👀

To keep Smart SIM affordable, we’ve limited it to apps that don’t gobble up endless data. That means social media and streaming are off the cards (for now, at least). On the flip side, you have more than 500 apps (and counting) at your fingertips, whether you’re on the train, on your travels or out on the town. Plus, it’ll give you a break from all that doomscrolling 😉
