Assessment 01

Rolling monthly plans

One-month agreements, slightly dearer per month, cancellable at any point.

The case for

You can leave whenever, which is exactly what an unproven address, a possible house move or a new network requires. Most budget brands sell nothing else.

The case against

You pay a small premium for that freedom, and promotional pricing on rolling plans changes more often.

The bottom line

Take rolling whenever anything about your situation is unproven. The premium is cheap insurance against a two-year mistake.

If you'd rather ask a person

We are independent: nothing for sale, no access to your account, and we will never ask you for a security code. We will read an offer with you, explain a clause, or talk a switch through.

Assessment 02

Twelve and twenty-four month plans

Fixed terms in exchange for a lower monthly figure.

The case for

Genuinely cheaper per month, and any early-exit charge is disclosed and itemised automatically when you request a PAC — so nothing is hidden.

The case against

Circumstances change: house moves, job changes and mast changes all outlast a discount. And the end date is easy to forget, after which the old price simply continues.

The bottom line

Take a fixed term only where signal and address are both settled — and diary the end date on the day you sign.

Assessment 03

Unlimited data

Unmetered on the handset domestically across all four mast owners.

The case for

No meter to watch, no overage risk, and genuinely honest at home. Three has priced it lowest among the mast owners for several years.

The case against

It bends in three places: tethering caps on some plan generations, brief queueing at extremely saturated masts, and fair-use ceilings abroad. Most people also buy far more than they use.

EvidenceThree months of usage in your network app
Typical overbuyAround a factor of two
Better tool for spikesA one-off add-on, not a permanent tier increase
The bottom line

Buy it only if three months of measured usage justify it — and read the tethering clause on your exact tier if you work from a laptop.

Assessment 04

Special mechanics

Rollover banks, application exemptions, loyalty pricing and per-unit billing.

The case for

All real features with real value: Sky banks unused data for years, VOXI exempts selected apps, Tesco links pricing to loyalty, 1pMobile charges only for consumption.

The case against

They are frequently treated as magic rather than as pricing, and each carries conditions that change over time.

The bottom line

Convert every mechanic into an effective cost per usable gigabyte, then compare like with like.

Assessment 05

The free protections

Spend caps, cash-terms rise disclosure and the annual review.

The case for

Every network offers a spend cap free of charge; since January 2025 mid-contract rises must be stated in pounds and pence before signature; and ten minutes a year of comparison catches silent drift.

The case against

Almost nobody uses any of them. The cap sits switched off, the rise clause goes unread, and out-of-contract prices drift upward unchallenged.

The bottom line

Set the cap on activation day, photograph the rise clause at purchase, and diary a ten-minute review once a year.
