Phone contracts, SIM-only plans and switching

Your phone is probably the bill you will have for longest. Understanding contracts, SIM-only deals and switching rules can save real money every year.

Handset contract or SIM-only?

  • A handset contract bundles the phone and the airtime (calls, texts, data) into one monthly payment over a fixed term.
  • A SIM-only plan covers only airtime; you use a phone you already own or buy one separately.
  • Ofcom found that customers who bought a handset and airtime together could often save by moving to a cheaper SIM-only plan when the contract ends, with estimated average savings of 75 pounds a year (from Ofcom's 2019 review, using 2018 data).
  • Before choosing, add up the total cost over the whole contract, not just the monthly price.

End-of-contract alerts (UK)

  • Ofcom rules require phone, broadband and pay-TV providers to alert you between 10 and 40 days before your contract ends.
  • The alert must say when the contract ends, your current price, the price after it ends, any notice period, and the provider's best deals.
  • If you are already out of contract, providers must tell you so and remind you of their best deals once a year.
  • Do not ignore these messages: they are your prompt to compare deals or switch.

Switching mobile provider by text (UK)

  • Text PAC to 65075 to get a switching code that keeps your number, or STAC to 75075 if you want a new number, says Ofcom.
  • Text INFO to 85075 to check whether you are still in contract.
  • The PAC is valid for 30 days; give it to your new provider, who must complete the switch within one working day.
  • Your old provider cannot charge you for any notice period after the switching date.
  • If you are still in contract, you may have to pay an early termination charge; your provider must tell you the charges before you decide.

Phones in the UAE and when travelling

  • UAE providers offer prepaid and postpaid plans; read the minimum term, data allowance and any roaming charges before you sign.
  • If you study abroad, compare keeping your UAE number on a cheap plan with getting a local SIM; the Tech Self-Sufficiency module covers roaming and eSIMs.
  • If you have a problem with your UAE landline or mobile service, complain to the provider first; if it is not resolved, you can escalate to the TDRA, as reported by Gulf News.

Getting the best deal

  • Check your real data use in your phone settings for the last few months and buy a plan that fits, not the biggest one.
  • Ask your current provider to match a cheaper deal you have found; Ofcom suggests this as a step.
  • Turn on spending caps or alerts to avoid surprise charges.
  • Keep your contract summary and first bill in your bills folder.

Practise in real life

Tick each one off when you have done it.

  • Check your current phone plan: monthly cost, data allowance, and when the contract ends.
  • Look at your phone's data usage screen and note your average monthly use.
  • Compare the total 24-month cost of a handset contract with buying the same phone outright plus a SIM-only plan.

Remember

  • Compare total cost, not just the monthly price.
  • UK providers must warn you 10 to 40 days before your contract ends.
  • In the UK, text PAC to 65075 to switch and keep your number.
  • Moving to SIM-only after a handset contract ends often saves money.
Note: Ofcom's savings estimate comes from a 2019 review using 2018 data, and prices change. The UAE complaint process is from a Gulf News report updated in May 2023 that covers service problems rather than billing specifically; check the TDRA website for the current process.

Check yourself

1. In the UK, what text do you send to get a code to switch mobile provider and keep your number?

2. When must UK providers send an end-of-contract alert?

3. Your handset contract has ended and you are happy with your phone. What does Ofcom suggest could save money?

4. How long is a PAC valid, according to Ofcom?

5. You have an unresolved problem with your UAE mobile phone service. What is the first step?
