How much do you currently pay for your phone bill? Checking your monthly spending is a good first step towards achieving your financial goals, and if you’re paying too much it’s worth seeing if you can get a cheap SIM-only contract by switching mobile providers.
If you’ve already paid off your phone or are planning to buy a new phone outright, opting for a SIM-only contract may be the cheapest option. You will need to make sure your contract is terminated, which you can do for free by texting “INFO” to 85075. Your network will reply to the text message with details – if your ‘early termination’ fee is zero, your contract is out.
As you’d expect, the amount you’ll pay depends on how much data you want, so I’ve broken this guide into sections to help you navigate based on your specific needs.
Before I delve into cheap SIM-only contracts, there’s one more thing to note: while there are a ton of mobile networks on the market, many of them rely on one of the big four operators: EE, Three, O2 and Vodafone. So if you know you have a good signal on one of these networks, check which providers are utilizing them to make sure you’re getting the same coverage.
