Customer Reviews
Good deal on a tablet contract
I was looking for a good deal on an iPad contract and Three had one of the best offers at the time. I checked a few places, and their monthly cost was lower for the data allowance I needed. The upfront cost was also reasonable. It felt like good value for money overall. The sign-up process was simple, making it worth the purchase.
Smooth switch for Home Broadband
I recently switched my Home Broadband to Three and the experience was surprisingly smooth. I ordered the 5G Hub online. The website clearly explained the different plans and the ordering process was straightforward. Delivery took about 3 days, and setting up the hub was easy with the instructions provided. I did have a quick question about my existing contract termination, and their online chat support was responsive and gave me clear answers. The speed has been consistent so far, and it's definitely an improvement over my previous provider. No issues with connectivity or drops. I'm happy with how it all turned out.
Good SIM only plan
I got a SIM only plan from Three a few weeks ago and it's been pretty good. Switched from another provider, and the process was easy enough. Coverage seems fine where I usually am. No complaints, it just works, which is what I wanted. Definitely makes things simpler.
Decent phone, slow delivery
I ordered an iPhone contract from Three last month. The phone itself is great, exactly what I expected. The price was competitive compared to other networks. However, the delivery took about 5 business days, which felt a bit long. It wasn't urgent, but it's something they could improve on. Customer service was helpful when I called to track it.
Fast SIM delivery
Needed a new Pay As You Go SIM. Ordered one from Three. It arrived in two days. Put it in, worked straight away. Good service.

Anyone know if Three usually has good Black Friday deals? Looking to snag a Pixel.
Thinking of switching to Three for a new iPhone. How long does delivery usually take to, say, Miami?
