Imagine having 2 phone numbers that people can contact you on, but only one phone. You can keep your work and private numbers separate, or keep a pre-paid card as a 'semi-burn' phone, but the benefits for frequent travelers is what I like most about the concept. 2 sim cards, 1 phone, no roaming charges on local calls to book accommodation and transport, but you're still contactable if your credit card company wishes to confirm a purchase (despite notifying them of your travel plans). This is the concept behind a dual-sim phone. As far as I know only Samsung and LG make dual sim phones, but the networks don't like it and don't promote them.
