Samsung Galaxy S21 FE 5G vs Samsung Galaxy S25 Enterprise Edition
Our Verdict: If you've got the Galaxy S21 FE 5G, the Galaxy S25 Enterprise Edition is four years of updates on from it. The S25 Enterprise Edition has a far higher-resolution main camera, 50MP against the S21 FE 5G's 12MP, and the S21 FE 5G has the bigger battery of the two, 4500mAh against 4000mAh, which should mean longer between charges in day-to-day use. The S21 FE 5G goes up to 256GB of storage, where the S25 Enterprise Edition tops out at 128GB, and the S21 FE 5G has the bigger screen, 6.4" against 6.2". If you're on the S21 FE 5G, the S25 Enterprise Edition is a real step up, but only worth it if the changes above matter to you.
If you'd rather pay up front, the S21 FE 5G is the cheaper buy at £130 SIM-free.
