How are you defining 'poor' in this context? Because I'd expect smartphone ownership to be more correlated with age than wealth, and at least in the UK it's quite easy to get a cheap Android phone for £99 on PAYG, or free on a £12.50/month contract. If you're willing to shop around, you can probably get a cheap phone on a £7.50/month contract (including data).
