Getting a SIM Card and Mobile Plan in the UK: A Guide for Australians
Getting connected is one of the first things worth sorting after you land in the UK. The good news: the UK mobile market is genuinely competitive, and SIM-only plans don't need a UK credit history.
SIM-only vs a handset contract
This distinction matters as a newcomer. A rolling SIM-only plan is just airtime, not a credit agreement, so most providers don't run a credit check on you for it. A handset contract, paying off a new phone over 24-36 months, is a credit agreement and typically does require a UK credit check, which can be genuinely difficult to pass with no UK credit history. Bring your own phone (or buy one outright) and go SIM-only for your first plan.
What it costs
The big four networks (EE, O2, Vodafone, Three) run their own SIM-only plans, generally at the higher end of the range. MVNOs (mobile virtual network operators) ride on the same physical networks at a lower price: giffgaff and Sky Mobile run on O2's network, Smarty and Voxi on Three's and Vodafone's respectively. Coverage is usually identical to the parent network; you're paying less for the same signal.

Frequently Asked Questions
Can I keep my UK number if I leave and come back?
Most providers deactivate a number after a few months of inactivity, so if you're doing a shorter stint and returning to Australia, check your specific provider's policy rather than assuming the number will still work.
Do I need a UK bank account to get a SIM-only plan?
Most SIM-only plans are paid by direct debit, which needs a UK bank account, though some providers accept a card payment instead. If you haven't opened a UK account yet, check the specific provider's payment options before signing up.
