Buying advice for Algeria

Both Samsung Galaxy A37 and Samsung Galaxy S21 Ultra 5G are sold in Algeria, but they fit different priorities.

Samsung Galaxy A37 is 7% cheaper at 65,000 DZD versus 70,000 DZD for the Samsung Galaxy S21 Ultra 5G, leaving room for accessories or a longer screen-protection plan.

Samsung Galaxy S21 Ultra 5G posts a stronger benchmark score, useful for heavier games and multitasking on Algerian carriers' busier 4G networks.

Samsung Galaxy S21 Ultra 5G reaches a higher main-sensor resolution at 108 MP, which helps with crops and lower-light photos.

Above 60,000 DZD, prioritise screen quality, fast charging, and a clear software-update commitment.
