EDITED TO ADD 01/08/2026 Visited Instant Mobile Fix for the second time and another great customer service from them, got my phone back in less then 24 hours all working thank you :)
Excellent service. Texted me a quote promptly, and came out and collected my iPad on Friday evening. It was ready for collection with a new screen and LCD the next morning. I would definitely recommend this guy if you have an accident with your phone or tablet.
