Please note, certain carriers may have policies preventing unlocking within the initial six months of use.

Honor 400 and eSIM: what to know

The Honor 400 supports eSIM, so you can add a data plan without inserting a physical card. In most markets it pairs a nano-SIM with an eSIM, and the phone can store more than one eSIM profile while using only a limited number at a time. Availability can vary by region and sales version.

  • Add an eSIM: the Honor 400 runs MagicOS on Android. Go to Settings > Mobile network > SIM management and choose the option to add an eSIM. Menu names can differ slightly between software versions.
  • Find your EID: dial *#06# in the Phone app and the EID appears with your IMEI numbers.
  • Travel tip: keep your home SIM active for calls and SMS, and set the travel eSIM as the mobile data line.
  • Turn off data roaming on your main line to avoid unexpected charges.

Install your eSIM Prime travel eSIM on the Honor 400 before you leave, over Wi-Fi, and switch it on when you land. Your main number stays reachable, so WhatsApp and calls keep working as usual.
