Yes — we're open Sundays. Phones don't wait for Monday to break, so neither do we. If your screen shatters at a Saturday-night barbecue, you can have it fixed Sunday before the work week starts — most phone repairs take about an hour while you wait. We're one of the few repair shops in St. Charles County open every day of the week.

How do I get to Sam's?

We're on Mexico Road in O'Fallon — one of the easiest addresses in St. Charles County to reach:

  • From Highway K: Head toward I-70 and turn onto Mexico Road. We're at 8621 Mexico Rd — just a few minutes from the K & I-70 interchange, with easy parking right at the door.
  • From I-70: Take the O'Fallon exit, drop south to Mexico Road, and you're practically here. Mexico Road runs parallel to the interstate, so we're a quick detour on any commute between Wentzville and St. Peters.
  • From Highway 364 (Page Extension): Follow 364 toward Mid Rivers, head north toward I-70, then west on Mexico Road into O'Fallon. Most of St. Peters, Cottleville, and Dardenne Prairie is within a 10–15 minute drive.

Prefer to talk to a human? So do we. Call (636) 294-7770 and the person who answers is the person who'll fix your device.

What should I bring?

Just the device — and your passcode if you'd like us to test everything fully before and after the repair. If it's a console with "no signal" issues, the console alone is fine (leave the cables and controllers at home unless you suspect they're part of the problem). For data recovery jobs, bring the device and, if you have one, the computer or drive you'd like your photos moved to.
