The Nokia 215 4G (2024) could be a good option to replace your Nokia 3G, but it has a few limitations. It doesn't have a camera, which could be a drawback if you need to take photos. However, it does have a diary, which is just what you need. The phone is simple, with 4G connectivity, which will keep you connected after 2026. It also has a 1450 mAh battery and a 2.8-inch screen.

Here are some key points to consider:
- Camera: Absent, which could be a problem if you need to take photos.
- Diary: Present, which meets your needs.
- Connectivity: 4G, which will keep you connected beyond 2026.
- Battery: 1450 mAh, which should be enough for moderate use.
- Screen: 2.8 inches, with a resolution of 240x320 pixels.
