I went today and got new batteries for my son’s iPhone and my iPhone. I also received valuable information on my kids phone. The battery has basically exploded and it wasn’t charging because I was leaving it on the charger too long because I was using cheap chargers. They were extremely friendly, professional and quick! I believe it was Han who worked on our phones and again he was extremely helpful and informative. I was charged a fair price for two new batteries a new case and a sturdy charger and cord. They are still setting up so things look a little unfinished, but don’t let the distract you. Soon they will be popping and there will be a line out the door for services . My Apple care lapsed on both phones so the price I would have paid at my provider or Apple would have been way more. I highly recommend this place

Hai Technical from Du Mobile did a great job. He fixed my phone’s battery and power button after another technician at the mall damaged it. The service was quick, professional, and very affordable. He explained everything clearly and really knew what he was doing. I’m very grateful for his help and would definitely recommend him to anyone needing reliable phone repairs.

New address is 37675 Niles Blvd Fremont, CA 94536; mixed with the Farmers Insurance; next to the pizza shop. Du and his brother were trustworthy. Du works the morning shift, and his brother works in the evenings. They fixed my Samsung A52 phone screen within a day. Pricing was $120. Background: My screen was complete black and wouldn't turn on. My alarm clock was functional, but the screen wasn't functional. FYI they do not accept credit for repairs, do take Zelle, and payment is completed prior to repair. It was a little concerning at first, but after the repair, I was satisfied with their work.

This is my second time using Du Mobile. They are quick, great price, exceptional service and friendly. New Ipad screen in about 20 minutes. I would recommend them for all electronic repairs.
