Fairphone 4, 5 & Gen 6 Series

Fairphone 4 and Fairphone 5 both support eSIM alongside a physical nano-SIM. Both are sold carrier-unlocked from Fairphone.com — no carrier permission needed to use a third-party eSIM. The FP4 (2021) commits to 8 years of software support; the FP5 (2023) extends that to 10 years, the longest of any Android manufacturer.

Key Takeaways

• Fairphone 4 and 5 both support eSIM + physical nano-SIM.
• Sold carrier-unlocked by default from Fairphone.com.
• FP4: 8-year software support through 2029. FP5: 10-year support through 2033.
• Battery swaps do not affect installed eSIM profiles — modules are independent.

Does Fairphone 4 or 5 Support eSIM?

Yes. Both models include an eSIM chip alongside the physical nano-SIM slot. The activation path is standard Android: Settings → Network & internet → SIMs → Add SIM → Download a SIM instead.

Phones purchased from Fairphone.com are factory-unlocked, so Roamix works immediately with no carrier contact required. Models bundled through specific European carriers (certain Vodafone or O2 promotions) may be locked — contact your carrier before purchasing an eSIM if you took a bundle deal.

Fairphone Models and eSIM Compatibility

Fairphone 4 vs Fairphone 5: What Changed

Both models use the same eSIM activation path. If longevity is the priority, the Fairphone 5's 10-year support window means it will still receive OS updates and security patches through 2033.

How to Activate eSIM on Fairphone 4 or 5

1. Open Settings.
2. Tap Network & internet, then SIMs.
3. Tap Add SIM or the + icon.
4. Select Download a SIM instead.
5. Scan the QR code from your Roamix email (arrives within 60 seconds of purchase).
6. Follow the on-screen prompts to complete the download.
7. Set Roamix as your preferred data SIM in the SIMs menu.
8. Enable Data Roaming for the Roamix SIM.

Battery Replacement and eSIM

Fairphone 4 and 5 have user-replaceable batteries. Unlike iPhones and Samsung flagships, the battery snaps out without tools. Swapping a depleted battery on a multi-week trip does not affect eSIM profiles — eSIM data is stored in the embedded SIM chip on the mainboard, which is a separate module entirely. You can replace the battery freely without touching your eSIM setup.

Fairphone and US Compatibility

Both models are designed for European markets. LTE connectivity works on AT&T and T-Mobile US networks:

• Fairphone 4: LTE bands B2, B4, B5, B12
• Fairphone 5: LTE bands B2, B4, B5, B7, B12, B28

5G on US-specific frequencies (n260, n261 mmWave) is not supported on either model. For US-bound travel with a Fairphone, Roamix will provide LTE-speed data on compatible partner networks.

Fairphone eSIM Troubleshooting

"Download a SIM instead" not visible: Your Fairphone may be carrier-locked. Phones from Fairphone.com are unlocked. If purchased through a carrier bundle, contact them to unlock the device before buying an eSIM.

eSIM installed but no signal abroad: Go to Settings → Network & internet → SIMs, confirm Roamix is set as the data SIM, and enable Data Roaming. Toggle Airplane Mode off/on to re-register on the partner network.

Battery replacement concern: Replacing the Fairphone battery does not affect eSIM profiles. The embedded SIM chip is on the mainboard module. All profiles remain intact after a battery swap.
