Let’s take a closer look:
Three Mobile call costs to 0330 numbers (2025)
| Plan Type | Are 0330 calls included? | Typical cost if outside inclusive minutes / PAYG | Notes |
| Pay Monthly Contract | Usually yes — if UK landline minutes are included | 35p per minute (outside allowance) | Calls to 03 numbers count like 01/02 numbers. |
| Pay As You Go (Standard) | Depends on bundle or allowance | 35p per minute | Standard landline rate applies if no inclusive minutes. |

Regulation Checker:
According to Ofcom:
‘Calls to numbers starting 03 must cost no more than calls to geographic numbers (01 or 02) and must be included in inclusive minutes.’
In practical terms:
- If your plan says ‘unlimited UK landline minutes’ (01/02), that should include 03 numbers.
- If you exceed your allowance or have none, calls to 0330 will be charged at the standard landline rate – never a premium!
- No extra ‘service fees’ should apply for 03 numbers under the regulation.
In Summary
On Three Mobile (2025):
- If your plan includes UK landline minutes calling a 0330 number is covered as part of that.
- If you’re on PAYG or have exceeded your inclusive minutes you’ll pay around 35p per minute, the same as you’d pay for any 01/02 landline call.
- No hidden premiums or surprise extra charges simply because it’s a 0330 number.
