Wrong activation

[brianseales]

How daft is this. SMARTY sent me two sim cards. I put one in my phone and they activate the other one. What rubbish is this.

What activation process did you use? Were you required to input the number; is there any chance of an error there?

If someone at Smarty made an error, although I can understand that it is inconvenient and frustrating, I'm sure that it can easily be sorted with a web chat to Support Team.

.....Or can you use the sim that has actually been activated?

Wow, not a great start @brianseales.

Does the wrongly activated SIM work? 
Did you particularly want the number assigned to the inactive SIM?
