Customer Reviews
Reliable service again
This isn't my first time with Three; I've had several SIM only plans and now this Home Broadband. What I really appreciate is the consistency. Every time I've ordered, the setup has been easy, and the service has been reliable. My 5G Home Broadband arrived just as expected, and the connection has been solid, same as my last SIM. They always deliver what they promise, which is why I keep coming back.
Super fast delivery!
I just got my new iPhone contract from Three, and it arrived so fast! The whole process was smooth from start to finish. I ordered the new Google Pixel contract, and it was here in like 3 days, delivered to my door. Seriously impressed with how quickly it got to me. I'm definitely going to shop here again for my next upgrade, and I've already told my friends about it!
Quick SIM only plan
Needed a new SIM only plan. Ordered from Three. It came in a few days. Setup was easy. Works fine. Satisfied with the service.
Good value for my money
I was looking for a new tablet for a while and came across Three during a sale event. I picked up a Samsung Galaxy Tab contract. The overall cost felt really fair, especially with the discount that was running. I compared it to a few other places, and this was definitely the best deal. The tablet came quickly, and the plan seems to be exactly what I need. It felt like a smart purchase and I saved a good bit of cash, which is always a win.

are the 'refurbished' phones from Three actually good quality? Or are they usually dinged up?
Thinking of switching from O2 to Three. Anyone done it? Is it a lot of faff to keep my number?
Is Three's 5G actually good? Like, compared to Verizon or AT&T speeds? I'm in downtown LA.
Hey guys, thinking of grabbing one of those new Pixel phones from Three. How long does shipping usually take to New York?
Anyone know if I can use my UNiDAYS discount for a new phone contract AND get one of those cashback deals? Or is it one or the other?
