Mobile phone users have been advised not to rush into an early upgrade from a network provider.
Many people nearing the end of their contract opt to sign up for a new handset and then look at mobile phone recycling options for the old model.
While this is a good way to make money on unwanted handsets, PC Pro has advised that even more cash can be saved by haggling with network providers.
The publication noted that many mobile phone users make a hasty decision to upgrade to the latest gadget – thus extending their existing contract.
However, it suggested that waiting until the tariff expires could put customers in "a much stronger position" to secure a better deal.
A number of providers often make courtesy calls a number of weeks, or even months, before a contract is due to expire.
By offering an upgrade at this time, many firms realise that the customer has little room to haggle, due to the remaining length of their deal.
"You might be itching for a new phone, but it's worth resisting early upgrade deals," the publication noted.
"Wait until your contract expires and you'll be in a much stronger position to get a discounted upgrade, as your provider will know you can leave at any time."
Having reached the end of a contract, customers have far more scope to search elsewhere for better deals.
Another way to save money is reading the small print on contract terms, as many firms offer customers the option of downsizing their package after nine months or so.
The subject of mobile phone contracts has been at the forefront of the news recently, as the EU vowed to outlaw long-term deals.
Officials have enforced legislation to prevent suppliers tying customers up to lengthy 36-month deals, although firms can still sell mobile phones on 24-month contracts.
