Adding 3 mifi Sim to MY 3 account

[TrevorS]

Hi , Does anyone know how to add a preloaded Data Only Sim that I use in my MiFi device to the My3 account?

I thought I would be able to just add the data only sim phone number to the account but can't see how to do it.

Hi @TrevorS,

If the new line is registered in matching details for you as account holder to the existing My3, then customer services have a process to link the accounts so that you can select which to access when you're logging in.

Thanks,
Jonathan
