I have an ID sim that I pay for but have never used it. I wish to use it in a mifi but how can I activate the sim without firstly putting it in a phone (I already have a ID mobile sim that I don’t want to change) 

is this possible as I already have an unlocked Mifi 

or would it be easier to buy another phone and use that on a personal hot spot basis.

thank you.

Hi ​@MCG 

 

I’d like to clarify that iD Mobile SIMs are primarily designed for use in mobile phones. While they may work in some MiFi routers, compatibility cannot be guaranteed across all devices, so you’re welcome to try it and see if it works for you.

Hi. Thank you but not really  answered my original question. How do I activate a sim without putting it physically in a phone?

Hi ​@MCG,

 

Thanks for your response, however there is no way of activating the SIM without it being in a handset. Once the SIM is activated, you can put it into the MiFi device to see if it works.
