Three UK is currently offering customers who purchase a BlackBerry smartphone on Pay As You Go from them free BIS for a year. That's right, no need to pay £5 a month for your BlackBerry data for one year.
One thing to note with this offer is that you must top up at least £10 every 28 days for the offer to stay valid. With your £10 top-up you can get the All-in-One 10 Add-on. This gives you 100 mins, 3000 texts and 500MB of data a month. 100 mins seems pretty low for some but now there's BBM 7 with voice calls so that may help out if you have other friends and family members with a BlackBerry device. Alternatively, you can top-up £15 and get the All-in-One 15 Add-on. This plan gives you 300 mins, 3000 texts and All-You-Can-Eat data every month. Since you won't have to pay the extra £5 a month for BIS, this plan sounds pretty good.
The offer is available to any customer who buys a Pay As you Go BlackBerry smartphone from Three UK and activates BIS from November 9th 2012 to January 31st 2013. If you already own a BlackBerry and just get a Pay As You Go SIM card from Three UK, activate BIS within the offer period, you are also eligible.
With Three UK's BIS plan you get email, 1GB internet data, BBM and App World access. To activate BIS on Three UK just text START to 38001, you should be activated within 48-hours.
There are currently four BlackBerry devices available on Pay As You Go from Three UK.
