Customer Reviews
Reliable service again
I ordered an unlimited data SIM again last month, just like I did for my last phone. It arrived fast, within 3 days to Manchester. The setup was smooth, and the speeds are consistent with what I got before. Good to know they're still reliable, that's why I keep coming back for SIMs.
Got a new Pixel
Needed a new phone. Got a Google Pixel on contract. Order process was quick. Phone shipped in 4 days. Working fine.

Anyone know if Three does those NHS or student discounts? Been looking at a new SIM plan and saving some cash would be sweet.
Thinking of switching to Three for a new phone. I'm in Manchester. How long does delivery usually take for a handset?
