sorted quickly once I rang

My first try at getting a new SIM through the website failed without a clear message, so I rang them, and the adviser sorted it in a few minutes. Plan is good value and the signal is fine at home. The only thing is the online sign up could be clearer about what happens next. Otherwise I'm satisfied with the service.

sim only deal done

Honestly really happy with this, signed up for a sim only plan on my phone during lunch and it was live by the evening. Data's been plenty so far and the app makes checking usage dead easy. Would switch again.

Switched for the data rollover

I've been on mobile contracts for years and know the game, so I was looking for rollover data and a fair monthly price. This ticked both boxes and the account set up was quick. I ported my number across and it took under a day. Signal is solid where I live and the bill matches what I was told. Nothing I'd change.

better than my old network

I was with a big name before and the signal was rubbish indoors, so I tried this instead as a cheaper option. The coverage is better where I live and I'm paying less each month. Setting it up took about twenty minutes on my phone. Not a bad switch at all for the money.

Needed a phone line that works at home

We needed a dependable mobile for my wife, who has a health condition and needs to be reachable at all times. The coverage at our house is patchy, which I did not check beforehand, and calls drop more than I'd like. Customer service has been polite but could not offer a fix. The plan is reasonable and the price is fair, though I would look at signal before signing up.

Cheaper than what I was paying before

I was paying a fair bit more with my old network for roughly the same data, so I compared a few and this was the cheapest by a decent margin. Signing up took about ten minutes on the site. The SIM turned up in two days and I was connected the same evening. No hidden charges that I can see after three months. Does the job, saves me money, nothing to moan about.

The bill was a bit higher than quoted

What struck me first was the bill arriving higher than I'd been quoted on the site, because of a charge for a second line I had not realised I'd added. It took a few phone calls to sort, and the adviser was courteous enough, though I did wait a while on hold. Once corrected it has been fine. Good enough for the price, but I'd want to read the small print more carefully.

Bought the sim only plan

Got the sim only plan with loads of data for not much. Ordered it on the app, arrived next day, popped it in and it just worked. Haven't had a single drop yet.

Bought a sim for my son

I bought a sim only plan for my son who is at university and needed a reasonable data allowance without a long contract tied in. The price was sensible and the set up was simple enough that I managed it between other tasks. He has had no problems with the signal in halls and his bill has been as expected each month. A sensible arrangement all round.

Needed something cheaper when I started working from home

I needed a cheaper plan once I started working from home and was using my phone as a hotspot a lot. The rate was lower than I'd been paying for the same allowance. Signing up was quick and the SIM was with me in two days. The only niggle is that the hotspot setting took me a while to find in the app. Once I had it sorted it's been reliable for my video calls.

Needed a proper contract for my mum

We needed a new mobile contract for my mum after her old provider put the price up without much warning, and she found it rather daunting to switch on her own. I rang the team first and they were patient with her questions, which I appreciated. The SIM arrived within a few days and the switch over itself was straightforward enough. Her bill is now clearer and a little lower than before, which pleases her no end.

better than the big networks for me

Compared with the big networks I looked at, this was noticeably cheaper for the same amount of data and I didn't have to tie myself into a long contract. I've been a customer for a couple of years now and the bill has stayed steady. The app is clear about what I've used and the reminders stop me going over. Support has been helpful when I've needed to change my plan. I'd stay with them.

Sim only and the price is right

Went for a sim only deal and the monthly cost is clearly lower than what I was on before, which is the main thing for me. The account was simple to set up online and the SIM came quickly. I've had no trouble with the bill since. Good value for what you get.

Simple and reasonably priced

The first thing I noticed was how clear the price was on the website, with no surprises tucked away in the small print. My daughter helped me set up the account and the young lady on the phone was very patient when I had questions. Everything arrived when it should have and the plan is working well for me.

way cheaper than my last network

My old network wanted nearly double for the same data so this was an easy switch for me. Got it set up in one go on my phone. Haven't had any issues since.

Got a sim only plan

Got a sim only plan for my first proper phone bill and I'm glad I went for it. Ordering the SIM through the app was easy and it turned up the next day in a plain envelope. Set it up on my own with no drama. Sometimes the coverage drops off on the tube but that's to be expected.

Got the 5g one

Got the 5g plan with the most data and it's mint. Speeds are quick in town and my mates are well jealous. Sign up was dead easy on my phone.

Took ages to sort my number

Honestly the plan itself is fine but getting my old number moved over was a nightmare. It sat in pending for nearly a week and nobody on chat could tell me why. Eventually it went through but I was without a reliable signal for a few days. The price is decent so I'm sticking with it for now.
