Following the launch of its flat-rate Xtreme Data service, Nashua Mobile plans to extend access to the service to more Nokia devices as well as to launch a premium version of the service for smartphone users with higher-end data needs.

Launched in March this year as an alternative to the BlackBerry Internet Service, Xtreme Data from Nashua Mobile is a fixed-cost data service priced at R59 per month.  The flat-rate service – currently available for a range of Nokia devices – offers customers data for email, Facebook, Twitter, WhatsApp, browsing and more.

To grow this community, Nashua Mobile has added many more Nokia devices to the ones already supported on the service. Xtreme Data has been extended to the Nokia Asha 300, 303 and 201. All of these devices boast the latest Nokia Browser, which offers up to 90% compression when browsing.  This is good news for users who don’t want to spend much more than R200 a month (including data) on their smartphones.

Now, Nashua Mobile will cater for the higher-end smartphones and data users with the launch of Xtreme Data Premium. With this Nashua Mobile will extend the service to include higher-end Nokia devices, such as Nokia’s Lumia family of smartphones: the Nokia Lumia 900, 800 (see our review here), 710 and 610.

At R139 per month, this Premium Xtreme Data service will cater for the more demanding user with up to 400MB of high-speed data before the Average Use Policy (AUP) kicks in and the data service is throttled or shaped. This compares to the 100MB users on the standard Xtreme Data package may use before the AUP takes effect. Consumers will also be happy to know YouTube is not blocked on the Xtreme Data Premium service – unlike the standard service.

Shaping or throttling means that your download speed is decreased once you have used a certain amount of data. In most cases, you will only notice the slower download speed when you are streaming data or downloading apps or games. For everyday services like WhatsApp, Email, Facebook and Browsing, you will still enjoy a normal user experience.
