Nokia 5110 – Back from the Dead (2022)
Reviving a classic Nokia 5110 with modern 4G hardware proves far harder than the original blog post from 2022 suggested, with no follow‑up ever appearing and commenters noting the deep technical and regulatory hurdles involved. The exchange broadens into nostalgia for robust 2G-era Nokia handsets and frustration that network shutdowns, VoLTE whitelisting, and carrier policies are rendering many otherwise functional devices obsolete, generating e‑waste. Several contributors describe mixed experiences with modern “dumbphones” and Nokia-branded reissues, arguing that today’s market still underserves people who want durable, simple, long‑battery‑life phones with basic LTE connectivity.
Project concept and feasibility
- Original article proposes reusing the Nokia 5110’s separate UI board (screen, keypad) with a new 4G modem+MCU board inside the old case.
- Several commenters say this is effectively building a new phone that just reuses case/buttons/display, not “just” swapping a modem.
- Many note that the promised “Part 2” never arrived (over two years later), reading this as evidence the task was harder than presented.
- Prior art is mentioned (e.g., DIY phones and kits) showing it’s possible in principle, but time‑consuming and non‑trivial.
Technical details: modems, VoLTE, and architecture
- Old feature phones often used a single CPU for both UI and radio; newer designs typically use modular 4G modems accessed via AT commands over serial/USB.
- For modular designs, a 4G module can sometimes present calls/SMS in a 2G‑like way, but VoLTE compatibility and carrier quirks complicate things.
- Several point out 4G voice is SIP/VoIP over a prioritized data channel (VoLTE); some argue it’s “proper” telephony, others criticize poor standardization and whitelisting.
- One commenter clarifies the project’s approach: replace the whole logic/radio board, not re‑use the original firmware.
Networks, shutdowns, and e‑waste
- 2G is gone or going in many western markets (notably North America and Australasia) but persists in parts of Europe and elsewhere.
- 3G shutdowns (e.g., Australia, parts of Europe) are causing problems: VoLTE‑incompatible or non‑whitelisted phones become unusable for voice, creating e‑waste.
- Some still successfully use old 2G phones where 2G remains and legacy SIMs are still valid.
Nostalgia and modern “Nokia” issues
- Strong nostalgia for 5110/3210/3310/6310‑era devices: robustness, week‑long battery life, instant boot, simple UI, and memorable models like n900, E‑series.
- Several want a 5110‑like phone with modern LTE/VoLTE and a modern battery, preserving the old UI/feel.
- Multiple reports that current Nokia‑branded feature phones (by HMD) feel cheap, have buggy firmware, poor call quality, and short lifespans; others report acceptable or good experiences, so quality is viewed as inconsistent.
Alternatives and “dumbphone” recommendations
- Commenters discuss modern rugged or minimalist phones (Sonim, AGM, CAT, etc.) as partial replacements: calls/SMS, hotspot, sometimes Android Go and sideloading, but not week‑long battery.
- Trade‑offs: availability by region, VoLTE support, band compatibility, price, and vendor support (some brands’ makers have gone bankrupt).
