Just a few thoughts to hopefully avoid disappointment from new customers :
1, Make it clear that Smarty runs on 3, advising people that if they haven’t already, they need to check the coverage of 3 where they live, work and socialise. People are attracted by Smarty’s “lemonade prices” but expect a “champagne service” when some people have poor or non existent coverage on 3.
2, Make it clear that Smarty is a mobile phone service, and should not be used as a long term replacement for home or business broadband, as pointed out in section 5 of the Smarty terms and conditions.
3, Make it crystal clear that to use Smarty abroad, the APN in people’s devices must be changed to “mob.asm.net”
