I've had a very positive experience so far. Far better value for money than my old network and coverage seems a lot better as I no longer experience grey areas of poor signal.

The customer service has been good, I've only messaged them once but they gave a quick and helpful response. It was easy enough to activate the sim and move over my number. Roaming also works smoothly - I've used it in Spain recently and my 4G was working as normal the whole time and with no extra cost.

London Three Mobile  
I had been with Three for some years and found it reliable and cost effective despite some signal drop out issues. I had a £10 per month unlimited texts and calls and 4GB data plan which suited me fine. That was until I got a letter from Three to say that, since my 12month contract had finished they were changing me to a monthly rolling contract for the same service but at £14 per month!!!

I went to my local Three store (Bloomfields Shopping Centre, Bangor, Northern Ireland) and spoke with the store manager, a most unhelpful individual. He told me, quite plainly, that my options were to take it or leave the network. I chose to leave the network but now wish I hadn't.

I found a deal with SMARTY, a wholly owned division of Three, giving me what I had at the price I had been paying and with a monthly contract. I initiated the changeover but quickly ran into issues, not least with their useless customer services agents. I instructed them to terminate the transfer process as they had frustrated me. They assured me it was terminated and I resolved to find another deal.

But they hadn't terminated, the transfer carried on and I was cut off from Three then cut off from SMARTY and left with no service! I had to go back to Three on a whole new deal and get a PAC code from SMARTY to get my old number back.

I gave the PAC code to Three, was told the usual 1 to two business days for transfer and waited. Nothing happened. I contacted Three customer services (SAVE ME from Indian call centres!!) to be told there had been "an issue" with the PAC code so they started again. Three days later, still no transfer so I called them again. Another "issue" with the PAC code so it was started again!

Now, after the third attempt, it's still not done!! And their customer services do nothing but ask the same questions again and again and make the same empty promises again and again. And so, 7 days later, I still have not had my original number transferred back. USELESS!

Northern Ireland Three Mobile  
I went into the Three store in Lewisham. Arrogant staff who were not very helpful and did not provide good information.

First day I have finally got the router and finally managed to get it activated useless instructions provided by the staff at three store and with in the product its self. I had to find a way to contact customer service and talk to a human and not get thrown around the houses to speak to the right person. Waste of time.

Router is now finally working, signal is rubbish even though it says my area should have a super strong signal.

I go on to the website to check coverage and I get this message: "We're really sorry. There's an issue with the network in your area at the moment.
We know that there's a problem with the service in your area and we're working on getting it fixed. Check back within 7 days for an update."

WHAT!? Not a good look, I've never been with Three before and was trying to look for an alternative to a crappy internet service currently provided by Sky over land line.

Thankfully I ordered online and have a 14 day returns period. Something to take note of if you order in store is that you don't get the 14 day return option so make sure you order online if you are going to try their home broadband so if it's rubbish like mine you can return. Will still trial it for the next 14 days and update if anything different from the above otherwise I will be returning everything.

Overall so far, waste of time and effort, not happy...

London, New Cross Gate Three Mobile  
Awful company. 2 years ago I went to the three store in Bedford to do an upgrade. Unbeknownst to me I was also given a whole new contract despite only wanting an upgrade. For over a year I was charged for 2 contracts. As soon as I realised I was being double charged I stopped paying the direct debit that had no correlation to my phone bill. I started receiving letters for a number I've never had asking for money. After receiving a letter stating that the number had now been disconnected and the remaining balance would soon be sent to a debt collector, I paid the balance and considered the matter resolved. I have now received requests for more money. On contacting Three I have been told that they have no record of the disconnection/cancellation letter despite having records of the other letters and I am therefore liable for the £70 they want from me.

Avoid them. Utter cowboys.

Bedford Three Mobile  
Avoid this company at all costs. I cancelled my account in 2016 and moved to EE. They said my account was cancelled. Two years down the line we noticed that three were still taking monthly ditect debits from our account. We didn’t use the phone in two years and was charged £800!! When we initiated a complaint with customer service we ended up speaking to a helpdesk abroad. They said because we didn’t use the PAC code to transfer to EE, they started taking payments from us again. Mobile phone companies have changed their policy as of yesterday and they now have to inform you if they keep your account open. However three should be ashamed of themselves. An absolute shambles of a company...

Coatbridge Three Mobile  
Woefully inadequate customer service, clearly under trained, didn’t understand whether vat was included or not when asked, (three different members of staff), two months in succession spending an hour at a time to try to resolve, but “computer says no”. Six year customer now looking at other opinions

Avoid them if you could. If you get any problem you will end up speaking to different people telling them same story , and no one there to help you. They cancelled my contract without my approval and still have been taking money from my account.

Watford Three Mobile  
I switched from Vodafone as I was lured in by the lower monthly cost and the roaming options. I now regret this hugely as I've had countless issues - data not working at all, extremely slow internet, texts not sending, unable to use virgin media wifi on the tube, phone number not properly transferred over etc. I then had to spend HOURS on live chats/ phone hepline ( the few times it worked) and received 0 help at all! Their customer service is a COMPLETE JOKE! No one calls back when they say they will and I was given the wrong advice MANY times which was a total waste of my time. Rather than help me, 3 customer service asked me the same questions OVER AND OVER again ( cause they clearly can't keep notes) and had to provide very sensitive information to prove my identity WAY TOO MANY TIMES! Customer Service at 3 refuses to be accountable for any faults 3 has and tries to claim there is no issue even when my data won't work at all in many areas. I had to have 8 lengthy, painful conversations to fix 1 problem because 3 refuses to listen. AVOID AT ALL COSTS!!!! WORST SERVICE PROVIDER!! I have been with Vodafone, O2, Virgin and GiffGaff and they are all far better than this awful network.Even when I tried to lodge a formal complaint, no one contacted me. Their customer service and technical teams are ABSOLUTELY USELESS and TOTAL TIMEWASTERS!
