Hello @Cc30,
You might be able to see two $18 plans because you were previously on the $15/month plan that has been removed and replaced with the new $18 plan. Public Mobile is giving you the option to remain on your old plan at the new rate of $18/month or you can opt for a slightly better plan that offers 1 gig of internet at the exact same price. The only condition is that you need to choose to switch into the new $18 plan yourself. As others have pointed out though, you should consider switching the plan on your next renewal date to avoid getting double charged for the current billing cycle.
