performance

1.1 GHz quad-core, 512MB RAMThis processor and memory pairing runs basic calls, texts, and simple apps only; do not expect to run modern smartphone apps or multitask.

battery

2500mAh, roughly 2–3 days standbyLight calling and messaging over a week is realistic, but screen-on time is roughly 6–8 hours in active use.

display

2.4 inch 240×320 TFT screenSmall black-and-white or limited-color text and icons; reading is tolerable only in low light, and scrolling feels slow.

connectivity

4G LTE and 3G UMTS bandsWorks on most GSM networks worldwide, but slower than modern phones; coverage depends entirely on which bands your local carrier uses.

durability

IP68 rating, waterproof to 1.5mCan survive accidental submersion in shallow water and dust; useful for work in wet or dusty environments.
