You can order 2 SIMS per account holder only.
You'll need to register the account with a different email address though as ID Mobile don't yet support multiple account logins in one dashboard or within the app.
It's one number per account so you will need to use different email address to register your second sim.
As long as your credit check results allows this, you can take out a second SIM card whenever you like. If not, then they recommend waiting up to 6 months before applying again. Nothing stopping you trying again in 2-3 months if you fail the credit check.
ID Mobile are looking into a family accounts feature but it isn't something available now!
If you require more than 2 SIMS you may have to get the other family member to register in their name or have another adult register it for them, as you need to be over 18 to register for the account.
