What is a number on a moshi time card

A moshi time card is for a game called moshi monsters, a time card lets you be a member for a certain amount of time e.g 3 days, 1 month, 6 month.
you can either buy a card at a list of shops, or you can buy a membership package for £4.95 per month, £23.95 every 6 months or the most popular and the best value £29.95 for 12 months and one time payment.
If you dont have a credit card then the moshi time card will allow you to have a membership package without the use of one.
hope this has come in handy to you and add me on moshi monsters my name is lulu1234567809
