Vaya has just moved from their great value 3G plans to newer 4G plans which were more expensive for the same value. However, they currently have 20% off, which makes it just marginally worse value than their really good value 3G plans, and you get 4G speeds. eg their old $17 plan which would've been my preferred plan had $700 of talk/text, unlimited standard SMS and 2GB data. The new $22 plan is now $17.60, and offers $650 worth of talk/text, unlimited standard SMS and 1.5GB data.
It sounds like the 20% off is valid for the full 24 month contract, the way I read this footnote: "20% OFF
-** Valid for applications from new customers received from the 8th April 2013. Valid until the 30 April 2013. Not available to customers with a connected service as of the 8th April 2013. The life of a plan is 24 months. 20% off valid for your plan access fee only and discounted for a total of 24 months."
I think it means that if someone applied before the 8th, but was connected from the 8th, they are not eligible for the discount. Do you agree? Someone could check with Vaya, if they want more clarification.
Vaya currently have a better reputation than Amaysim, and provides 4G vs the Kogans and Aldis, and is much cheaper than Boost 4G.
edit: They changed the condition on the 9th of April. It now states: "20% OFF
** Valid only for applications from new customers received from the 8th April 2013 onwards. Not available to existing customers with a service already connected prior to the 8th April 2013. The 20% off is valid on your plan access fee only and it applied as a monthly discount off your plans access fee for a maximum of the next 24 monthly invoices, the promotional discount is valid for both month to month and 24 month contract options."
So, it seems they have taken off an expiry date, which might mean they could take it off anytime. Also, they have clarified that it is now available on month to month signups too (it wasn't clear before).
Would be very tempted if there wasn't a 24 month contract involved!
These guys haven't even been around that long!
