The Kyocera DuraForce Pro 3 is the first DuraForce model to include eSIM. Earlier models — DuraForce Pro 2, Ultra, and older — use dual physical SIM only. US models are sold through Verizon; Japan models through au (KDDI). Both are carrier-locked and require an unlock before a third-party eSIM like Roamix can be installed.
Key Takeaways
- DuraForce Pro 3: eSIM supported.
- DuraForce Pro 2, Ultra, and older models: NO eSIM hardware.
- US: sold through Verizon (carrier-locked). Japan: sold through au/KDDI.
- Carrier unlock required before Roamix installation.
Does the Kyocera Series Support eSIM?
Only the DuraForce Pro 3. Earlier DuraForce models (Pro 2, Ultra) use dual physical nano-SIM only. Additionally, because all DuraForce phones are sold carrier-locked (Verizon in the US, au in Japan), the device must be unlocked by the carrier before any third-party eSIM can be installed. Contact your carrier directly to initiate an unlock request.

Troubleshooting Kyocera DuraForce eSIM
"Add eSIM" option missing: Either your model is the DuraForce Pro 2 or older (no eSIM hardware), or the Pro 3 is still carrier-locked to Verizon or au. DuraForce Pro 2 and older cannot use eSIM at all. DuraForce Pro 3 requires unlock from Verizon (60 days active + device paid off) or au (KDDI unlock procedure).
eSIM installed but no data abroad: Settings → Network & internet → Mobile network → select Roamix eSIM → set as default data SIM → enable Data Roaming. Toggle Airplane Mode on/off to force network registration.
QR code scan fails in field conditions: Ensure camera lens is clean — rugged use can obscure the lens with dust or debris. Use "Enter activation code" (manual SM-DP+ entry) as a more reliable alternative in field conditions.
Verizon or au error during eSIM activation: If you see a carrier error during activation, the device may still be locked. Contact Verizon (1-800-922-0204) or au (0077-7-111) to confirm unlock status before retrying eSIM installation.
