Brilliant

Bought the top end S21 ultra 16ram and 512GB and it is a beast. You won't regret for sure. Cheapest price on the internet. And it is tracked, which is always good to follow your order.

Samsung Galaxy S21 Ultra 5G Dual Sim Black | 512GB | 16GB RAM

Very happy to purchased this flagship phone. After ordering it on Black Friday, found a good deal when compared to other online retailers. I was little sceptical at first about this site and seller but after going through some reviews and researching about this website authenticity, i made up my mind to go for the the kill. I also verified that your money is protected with PayPal so i would have peace of mind if anything goes wrong. Now i have been happily using this phone since last 2 weeks and very happy to be OnBuy customer and seems like i made a good decision. Although, the delivery of the phone took nearly 2 weeks to arrive at my destination in UK

Now, to the phone, the 16Gb RAM and 512 Gb storage backed with 5000 mah battery is a beast of a device. Its working flawlessly for last 2 weeks and have not had any complaints.
I will be using the phone further over coming days and will update of any changes.
Thanks Onbuy for the lovely device i own right now.

I think very good phone, very fast, light, beautiful colors in the pictures.The phone itself is very beautiful!The cameras on the back could be in a plane with the back cover, but I’ll get used to it.I don't know anything about battery life yet.But definitely better than my previous phone(S10+)!10star star to the merchant!Thank you very much OnBuy!

Great Phone !

Difficult to get the Snapdragon processor in the UK (which is faster) and also impossible to get 512Gb RAM - so went to Onebuy. Camera in this device is phenominal !

galaxy S21 ultra

one of the seal's on the box had been cut . which means it had been opened. but all of the items looked perfect ie unused (I hope) . Apart from that it looked perfect. I'm over the moon with it . Delivery estimate was spot on . I have had 3 items delivered in one week all spot on or delivered before estimated time . Never used ONbuy before but will be my first to go to in the future . Thanks OnBuy

I was very nervous about buying this as its a lot of money but much cheaper then other sites and then after ordering I discovered its was coming from Hong Kong and would take a week to arrive !!!
But I was able to track it all the way and its perfect in every way no problems at all very pleased and will buy from them again very Good service thankyou This is true and not written by one of their staff lol
