Save time, and get $5 bonus credit* by activating your new Crazy John’s prepaid service online NOW!
It is simple, quick and easy. Here's what you need:
Follow the steps and you will be activated in a matter of minutes. Note, if you are keeping your existing number, the process may take longer depending on your service provider prior to joining Crazy John’s.
If you prefer, you can activate your service over the phone or in one of our stores, but during busy periods there may be considerable delays and you will not get any bonus credit.
*Terms & Conditions for $5 Bonus Credit:
15 day credit expiry applies when you activate a SIM card WITHOUT included credit (eg. a $2 SIM pack). However if you activate a SIM card WITH included credit (eg. $14.95/$19 SIM packs) then no additional days will be added to the included credit expiry period. Therefore if your pack comes with $55 included credit and 30 day credit expiry, activating online you will get $60 included credit with the same 30 day expiry. Bonus credit can be used on standard talk, text & more. Some services excluded. For full prepaid terms and conditions click here.
