Reliable service, consistent savings

I've been with Honest Mobile for over a year now, and I just renewed my Smart SIM plan. It's always been straightforward. My bill has actually gone down, which is the main reason I keep coming back. Switching the plan was super easy online, just like last time. No issues with coverage either, which is a big plus for me.

Decent service, minor hiccup

I signed up for a SIM-only plan and generally, it's been a positive experience. The sign-up process was clear, and my physical SIM card arrived exactly when they said it would. Signal strength has been consistent, and I appreciate the carbon-neutral aspect of the service. However, I did have a small issue with setting up data roaming bolt-ons through the app initially; it took a couple of tries to get it to register, but it eventually worked. Customer service was responsive when I contacted them about it. Overall, good value and I'd recommend them, just be prepared for a potential minor tech snag.

Smooth switch, reliable network

I moved my number over to Honest Mobile last month, getting a 5G mobile plan with an eSIM. The ordering online was simple enough, and they walked me through the eSIM setup really well – it was actually quite easy. I had a small question about international calling add-ons and used their online chat; the support agent responded within minutes and was very helpful. Signal has been strong and consistent, even in areas where I used to struggle with my previous provider. The whole 'carbon-neutral' aspect is a nice bonus, but it's the reliability and easy management through their app that really stands out. My bill also decreased already, which is a nice touch.

Love my new mobile plan!

Switched to Honest Mobile and got their flexible mobile plan, and it's been fantastic! The eSIM setup was a breeze and I was up and running in no time. Their network is super fast, I get great 5G speeds everywhere. Plus, knowing it's an eco-friendly mobile service makes me feel good about my choice. I'm telling all my friends about it!

Fantastic service, genuinely carbon neutral!

I absolutely love Honest Mobile! I got one of their 5G mobile plans and it's been incredible. The speeds are fantastic, and I've had zero problems with coverage, even when I'm out and about. What really seals the deal for me is knowing they're a B Corp and genuinely carbon neutral. It's so refreshing to find an ethical mobile contract that actually works great. I'm telling everyone about them; my friend already switched after I raved about it! The loyalty discount is a nice touch too, my bill gets cheaper!

Easy switch, good value

So I finally got around to switching from my old mobile provider, and my friend told me about Honest Mobile. I went for a Classic SIM plan, and it was pretty painless, honestly. They even helped me keep my number, which I thought would be a nightmare but nope, it was fine. The service has been solid so far, no dropped calls or anything. Feels good to support a company that's trying to do things better for the planet too. Definitely a good move.

Consistent service, easy switch

This is my third time using Honest Mobile, and like before, the experience was smooth. I needed another Smart SIM for a new phone, and the order process was just as straightforward as my first one. The SIM arrived quickly, activated without any issues, and I was able to keep my old number easily. Their loyalty discount is a real plus too, makes staying with them a no-brainer.

thinking about switching from Giffgaff. how's the signal quality with Honest Mobile? same network coverage or better/worse?

A Amber Beaumont 1 month ago
I switched from Giffgaff last year, and honestly haven't noticed much difference in coverage. They both use the O2 network, so it should be pretty similar wherever you are.

C Chris N. 1 month ago
Yeah, pretty sure they piggyback on O2's network, so if O2 is good where you are, Honest Mobile should be too. Not better or worse than other O2-based providers really.

My friend just signed up and got a referral code. If I use it, do we both get something or just them?

D Dan P. 2 months ago
Both of you get credit, I think it's like 10-20 quid each off your bill.

R Rachel Okafor 2 months ago
Yeah, it's a mutual thing. Both you and your friend get some bill credit. I referred my sister and we both saw a discount on our next bill.

hey, was looking at Honest Mobile. i'm in new york, will this even work there? or is it uk only?

K Kate Silva 2 months ago
Yeah, it's a UK network. Like, all their stuff is geared for the UK market. You'd probably have trouble trying to get service in NY.

M Megan Romero 2 months ago
They are based in the UK and their plans are for UK numbers. You can roam internationally with it, but it's not meant to be a primary service if you live outside the UK.

Hey, thinking about switching to Honest Mobile. How exactly does that whole bill reduction thing work? Is it automatic or do you have to do something?

P Phil Marsh 2 months ago
Yeah it's automatic. The longer you're with them, your bill just slowly goes down. Pretty cool.

It's their loyalty discount. I've been with them for almost a year and my bill is noticeably lower than when I started. No codes or anything, just happens.

Any NHS discount for Honest Mobile? Or is it just student discounts?

G Greg Bennett 2 months ago
I think they do have an NHS discount. Check their site, but I remember seeing it listed somewhere.

Yes, they offer an NHS discount! My partner got one when signing up, so it's definitely a thing. Worth looking into.
