spusu UK Reviews 

Excellent initial experience. I needed an eSIM to get me online when away.
Customer service could not have been more helpful.
Signal, speed, everything excellent.
Only used them for a month or two myself but signed my Mum up and it continues to be excellent for her.
My contract was up so decided to swap to Spusu. Stupidly I chose a low plan, 5Gb, to start and get my number ported to them. Once this was done I tried to upgrade to a more generous plan only to be told that yes I could upgrade to that plan but not at the advertised cost.
This because I was already a customer.
Valued customer? It doesn't appear so.

Long story, short, this must be the quickest port in then port out of a number with me leaving Spusu.

The App also needs some work, but that's incidental, showing nearly a Gig of EU roaming when the nearest I have got to the EU was drinking a bottle of French wine!!
Yes, it was only about £5 a month but that's not the point.
Take a leaf out of Giff Gaff's book

Value your customers, grow long term business.

You pay for what you get and this is a cheap mobile service. Most of the time I used Spusu I had issues, mostly I could not make outgoing calls. I also had issues setting the eSim up which took ages to sort out. Customer service is really, really slow and frustrating (I don't do calls to call centres so I was reliant on messaging to get help). If you just want data and texts (with no images) then I guess it's ok, otherwise not worth it.

Phone answered very quickly, and Julian answered both of my queries to my complete satisfaction.

I've just signed up to Spusu and had a query so phoned Customer Services. They answered straight away and responded super helpfully to my query. So far I'm very happy I've switched over to them.

If you lose your phone on a Sunday what do you do when your customer service is closed?

The good part is they answer the phone promptly. That’s about it.
I ported my number to Spusu and was subsequently unable to sign in to iMessage. I’ve not had this problem when switching before. Followed all the steps and it is not resolved. Customer support, though friendly, basically read out the Apple help page.
They also set the eSIM’s default to LTE. Not 5G. You have to manually choose 5G. So while they advertise 5G, you don’t get it by default, in other words they are trying to save money by having you not use 5G.
I’m going to immediately move back away from them.

Update 5/5/26: Spusu was adamant that they had ported the number correctly and it wasn’t their problem. So I moved to Smarty and ported my number again. Everything immediately worked with Smarty, iMessage, 5G.
Spusu is now trying to bill me for the whole of May when they couldn’t provide a full service and that’s the reason for cancellation. Terrible company, stay clear.

Alex was great, he went straight away into service mode and gave me the best customer service experience

I’ve been with Spusu since January 2026, I have been impressed with my sim only deal. So today I checked out roaming charges for my trip to Florida in September, and found out that calls will cost 20 pence per minute. Now Spusu is even better, anyone wanting to move from another network should look at Spusu, I would say you won’t be disappointed!

Spencer dealt with my request to upgrade quickly and efficiently

Carl was fantastic and so friendly and helpful . Sorted out what I needed another 1 g each for myself and kids and all for an extra £1 each! Amazing deal, thanks Carl, top bloke! 👏👌😃I won't use any other company now only spusu which does best deals ever!

Ryan at Spusu was fantastic. He answered my call incredibly quickly and was clear, friendly and polite. He fully understood my request and actioned it instantly, confirming I had what I needed before closing the call. Excellent customer service from a company I’d highly recommend.

Wanted to port am old number from EE to Spusu. Julian was patient and guided me through the process to port. Excellent service highly recommend

Alex resolved issue straight away in a friendly and efficient manner

Excellent customer service. My query was answered quickly and professionally. Answered all my questions without hesitation. Just what you need from a customer service.

Service is poor and even asked for the postcode of a field I was in when I still had no service - despite constantly telling me I had 5G. Just not as good or as fast as EE or O2 direct and for not enough of a saving to make it bearable.

I spoke to Julian who helped me to set up my spusu account.
He was extremely helpful - friendly, clear and patient. This was my first contact with spusu and I already have a very good impression of the organisation. Julian answered the phone within a couple of rings - so no being put on hold in a long queue and, best of all, no interaction with an AI chatbot or some other automated system. What a pleasure to be able to speak to a real human from the start of the call with no waiting time!

Easy setup, UK reception good, roaming EU worked. Good customer support when am eSIM transfer to a new phone was needed

I've was with EE for years over many handsets. Switched to Spusu as they were so much cheaper. Even though they run on the EE network I get better 5H signal than I ever did with EE direct, go figure that one. Would recommend.

Ported my number, texting doesn't work, spoke to spusu, bad customer service, I'm leaving.

I read the reviews, i agree with them.

I switched to Spusu because I work in the countryside and Vodafone had almost no reception there. Spusu is cheap and reliable wherever I need it. I also use it for roaming in Turkey, and the pay-as-you-go roaming has been reliable and cheap too.
