I never expected to get services from the staffs in Mobile Relation. Best compared to Singtel Hello stores.
Staff here are genuinely helpful and recommended the best mobile sets
I will definitely recommend more of my friends and relatives to them.

Just bought my 18 pro max from Mobilerelation Aljunied. Tried searching at Apple Store and other places they are out of stock. Was so happy when I found out they have ready stock came down 1 hour after messaging them via WhatsApp. They are friendly and professional, sold my 17 pro max and topped up a little for this new phone!

Small, no frills shop with excellent service. Came in to buy one of the last few iphone 17 on this island and managed to get all the data transfer on the spot. Super friendly and reliable service :)
p.s: went to their outlet in ang mo kio to replace battery for my old iphone and the experience is just as pleasant! :)
