Nokia 638 Technical Specifications

Nokia 638 released back in 1996. It was one of the iconic devices that paved the way for modern mobile technology. The Nokia 638 included support for headphone usage. Though it lacked advanced connectivity options like Wi-Fi or Bluetooth, it excelled at its primary purpose – reliable and uninterrupted voice communication.

Design and Network

The Nokia 638 was a sturdy and straightforward device with dimensions of 160 x 53.3 x 31.8 mm. It may feel bulky by today's standards, but back then, it was a groundbreaking feat of engineering. This monochromatic wonder operated on the AMPS (Advanced Mobile Phone System) network, a predecessor to modern cellular networks. It supported the trusty Mini-SIM card, and users had the option of a single-SIM configuration.

Display and Colors

The Nokia 638 boasted a monochrome display, characteristic of the phones of its time. While it may not have been the most visually stunning, it provided a clear and legible interface for calls and basic tasks. The phone was available in classic black, giving it a timeless appearance that remains iconic in the mobile industry.

Battery and Talk Time

The Nokia 638 offered users the choice between two battery options: the Slim NiMH Battery (BBT-6L) with a capacity of 470 mAh and the Extended NiCd Battery (BBT-6S) with a capacity of 950 mAh. While the latter added some weight to the phone, it also extended the talk time to an impressive 120 minutes and standby time to 26 hours. The Slim NiMH Battery, on the other hand, offered 60 minutes of talk time and 13 hours of standby time.
