Understanding SIM & Network Options

myFirst Fones are available with either an eSIM or Nano-SIM. The option you choose affects how the Fone can make calls, send messages and connect with approved contacts. 

eSIM Models (R2, S4, S3+) 

eSIM models connect exclusively through the myFirst global network and cannot be moved to another mobile provider. 

The myFirst plan costs NZ$12 per month and includes unlimited data. 

Because this is a data-only service: 

  • The Fone does not receive a New Zealand mobile number.  
  • Standard mobile calls and SMS messages are not supported.  
  • Calls and messages are made through the myFirst Circle app using mobile data.  
  • Approved contacts must have the myFirst Circle app installed to communicate with the Fone user.  

This option works well for families who are happy to keep all communication within the myFirst Circle app. 

Nano-SIM Models (S3, M1, R1C) 

Nano-SIM models include a myFirst Nano-SIM card at no extra cost. 

When using the included myFirst SIM, the Fone connects through the same NZ$12 per month unlimited-data plan. It operates as a data-only service, with calls and messages handled through the myFirst Circle app. 

The key advantage of a Nano-SIM model is flexibility. You can remove the myFirst SIM and replace it with a compatible New Zealand SIM from a provider such as 2degrees or One NZ. 

With a local mobile plan, the Fone can have: 

  • A New Zealand mobile number  
  • Standard mobile voice calls  
  • Standard SMS messaging  
  • Communication with approved contacts who do not use the myFirst Circle app  

Choose a plan with at least 800 MB of mobile data per month so the Fone can continue supporting location updates, GPS tracking and its connected safety features.
