Troubleshooting Hammer Rugged eSIM
"Add eSIM" option missing: Your Hammer model does not have eSIM hardware (only Blade 3, Blade 5G, Explorer PRO, and Construction do), or the device is carrier-locked. Check Settings → About phone → Model to confirm your exact model. Budget Hammer models cannot use eSIM.
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 re-register on the network.
QR code scan fails in field conditions: Ensure the camera lens is clean — Hammer devices can accumulate dust or mud on the lens during field use. Scan in a well-lit area. Use "Enter activation code" for manual SM-DP+ entry as a reliable alternative to camera scanning.
"eSIM not supported": Your Hammer model does not have eSIM hardware. This is a hardware limitation and cannot be resolved by a software update. Only Blade 3, Blade 5G, Explorer PRO, and Construction have eSIM chips.
