The documents are broadly the same for every contract type. What differs sharply is the threshold — because the amount of credit involved varies enormously between a flagship handset and a data-only SIM.

Understanding that is the difference between a declined application and an approved one, since you can often change the outcome simply by asking for less.

Threshold by deal type

Deal type Credit involved Threshold
Two-device bundle Two handsets financed Highest — assessed on combined value
Flagship handset contract One expensive device High
Mid-range handset contract One moderate device Moderate
SIM-only None — service only Low
Data-only None Lowest
Prepaid None — not a credit agreement No assessment at all

The documents stay the same

Across all contract types you will generally need identity, proof of address, proof of income and banking details in your own name. See what documents are needed.

What changes is how much scrutiny the affordability calculation applies, and how much room you have if your position is marginal.

Requirements specific to certain types

Using this to your advantage

If you expect difficulty, the deal type is the lever. Moving from a flagship to a mid-range handset, or from a handset contract to SIM-only, materially changes what the assessment is being asked to support.

A counter-offer from a provider — a cheaper device or smaller bundle — is that same lever applied by them, and is worth taking seriously.

Frequently asked questions

Are the documents different for SIM-only?

Broadly the same, but the assessment threshold is lower because no device is financed.

Which contract is easiest to be approved for?

Data-only, then SIM-only. Prepaid involves no assessment at all.

Does a bundle need more documents?

Not more documents, but affordability is assessed on the combined value of both devices.

Can I change deal type after being declined?

Yes, and applying for something smaller often changes the outcome.
