Item was delivered promptly and was as described. Only issue on setting up the phone was apple news app was configured for India, so I had to work out why it was initially unavailable.
Amazing delivery time. Phone arrived within 24 hours of ordering it . Not tested the phone yet as it is X-mas present but all seems good . Box is sealed etc. happy. Thank you.
Superb from start to finish - great price - ordering was very simple, delivery was fast and free - what's not to like. Buy with confidence from A1 Tech Deals - I know I will not hesitate to do so again in future.
Very quick standard delivery for a brand new mobile, well packaged. Ordered two items which came separately, the second arrived a day later, but still an excellent first time experience with A1 Tech
Really excellent service, kept well informed by email of order progress and it was delivered in 3 days. I would definitely use again. Don’t buy tech until you have checked A1 Tech Deals.
Needed a new phone so looked online. A1 Tech Deals were cheaper for what I was looking for. They had good reviews so took a chance. Phone came within two days. Really pleased with it. Thankyou
A1 Tech Support get a high score from me - they gave helpful suggestions regarding finding a fix - but also agreed promptly to a return/refund when the suggestions didn’t fix the issue.
