Design and Build
The Siemens U10 features a substantial design compared to modern standards, with dimensions of 154 x 55 x 29 mm and a weight of 184 grams. This gives it a solid presence in the hand, typical of early 3G phones that included numerous features in a relatively small form factor. The phone accommodates a Mini-SIM, the standard for the time. Its construction suggests durability, with a titanium finish adding a touch of elegance often sought by business users.
