display

1.77-inch, 128x160 screenThis is a small monochrome-style display with 116 ppi, suitable only for basic calls, texts, and time checks, not for browsing or video.

storage

64 MB internal, microSD slotThe 64 MB on-device storage holds almost nothing; you will need a microSD card (up to 32 GB) for any media or apps beyond the essentials.

battery

2500 mAh Li-Ion batteryWith this capacity and the tiny screen, you can expect roughly 3 to 5 days of light use, or around 2 days with regular calls and texts.

connectivity

Dual microSIM, no 4G listedSupport for two SIM cards is useful for work and personal lines, but the lack of 4G specs suggests this is a 2G/3G device only, limiting data speeds to pre-smartphone standards.
