Modem Repair: Estimated Labour Charges and Prices in Nairobi
Provider: Pro-Logic Technologies, Kangari Building, Nairobi
The cellular modem is the component responsible for all mobile network communication — voice calls, SMS, and mobile data (3G, 4G LTE, 5G). On most modern smartphones, the modem is integrated into the SoC (for example, the Snapdragon X-series modem built into Qualcomm SoCs). On some devices, particularly older iPhones, it was a separate Intel or Qualcomm chip mounted independently on the logic board. Modem failure means the phone cannot connect to any cellular network, regardless of SIM card or network settings.
Symptoms of Modem Failure
- No network signal despite a working SIM card confirmed in another phone
- "No Service" or "SOS Only" displayed persistently and not resolved by network settings reset
- Calls failing while data and Wi-Fi work normally (or vice versa)
- Baseband software errors appearing in diagnostic reports
- Phone worked immediately before water damage and now shows no signal
Estimated Modem Repair Costs in Nairobi (2024–2025)
| Service | Labour (KES) | Parts (KES) | Total Estimate (KES) |
|---|---|---|---|
| Modem re-flow / BGA rework (integrated in SoC) | 3,500 – 7,000 | N/A | 3,500 – 7,000 |
| Standalone modem chip replacement (older iPhones/Androids) | 4,000 – 8,000 | 4,000 – 12,000 | 8,000 – 20,000 |
| Full board replacement (if modem fault non-isolatable) | 8,000 – 40,000 | Included | 8,000 – 40,000 |
What Affects the Price?
When the modem is embedded in the SoC, it cannot be replaced independently — repair involves SoC rework or full board replacement. Standalone modem chips on older devices are more tractable and less expensive. Water damage cases often require corrosion cleaning around the modem before chip-level faults can be properly assessed.
