PAYG contracts are great for people who don’t want a long-term contract, or who would have trouble with a credit check. They are also a good option for parents who want to give their child a mobile phone but want to have more control over the budget. Even when a mobile is out of credit, it can still be used to make emergency calls. People who have very light usage of their phones will also benefit, as many contracts provide more calls or data than they would ever use. You can use your mobile phone for roaming when abroad, but you should check the costs before doing so.
