Flew in from Toronto and went directly here via the Heathrow Express to get a UK SIM card for my Android phone. Super friendly, helpful service. Swapped my SIM out for me and didn't charge me anything. Simply directed me to Lebara's online deals. You get twice the data for same price if you buy it online. Got 15GB for £10. More than enough for our 2 weeks in England. Thanks!

Replaced screen. Quick turnaround and professional, they sorted out an initial problem efficiently, providing a detailed explanation of the fix needed and made. Also very good value compared to Apple or some of the other high street chains. Highly Recommended !

Very honest team and good products! My iPhone wouldn't charge anymore and the tech guy said it was simply clogged with dirt and cleaned it for free.. I could've been charged any price for repairs and I wouldn't have known it was just dirt causing the issue! So I bought a charging cable.. price was very reasonable and cable feels to very good quality! A trusted place I would recommend to everyone!
