UNL20 is a new code valid from 11/01/15 to 31/01/15 and is better than the previous code HALF50 (50 % off).
For $20 you get 5 GB of data and 30 days of unlimited:
- Standard calls to landlines and mobiles
- Calls to 13 and 18 numbers
- Standard SMS and MMS
- Voicemail
Plus get $10 of credit if you use my referral link: http://amaysi.ms/r/RS8fQMN0
Note: The T&Cs for this promotion state that it is for "new orders" rather than new customers. So existing customers may be able to take advantage of the deal by making a new order and porting their existing amaysim number to a new SIM. But I have not confirmed this yet.
So $20 is just the price of the first month and $44.90 is the price for every other month?
