12, 24 and 36-month phone contracts

The short answer

Pick the term that matches how long you will happily keep the phone - not the lowest monthly figure on the page.

How the terms feel

• 12 months - higher monthly, freer exit, fewer handset-heavy deals
• 24 months - the usual balance of monthly cost and commitment
• 36 months - lowest monthly for many flagships, longest lock-in

True cost still rules

A 36-month deal can look gentle every month and still cost more overall than a sharper 24-month package. Always run monthly × months + upfront.

Who should take 24 months

• You upgrade roughly every two years
• You want a wide choice of handset deals
• You like a clear midpoint between flexibility and monthly cost

Who should consider 36 months

• You keep phones for three years or more
• The monthly saving is large and the true total still looks fair
• You are confident about coverage and customer service on that network

Who should stay shorter

• You expect a big life change - moving abroad, a new job, a different network need
• You prefer SIM-only freedom after a year
• You are trying a network for the first time

Pitfalls

• Stretching to 36 months for a phone you already suspect you will replace sooner
• Ignoring early exit fees when the monthly price feels irresistible
• Comparing different terms without normalising to true total

Next step

On phone deals, shortlist the same handset on 24 and 36 months. Keep the totals beside each other and choose the term you will still be happy with halfway through.
