Why 2026 Tax Refunds Matter Before Changing Your SIM

If you are self-employed, work as a freelancer or contractor, or own your own business, you can normally claim part of your phone plan as part of your overall tax return. This is because your phone plan is considered part of your utility bills. So, for example: if 60% of your usage is for work, you can claim 60% of your overall phone plan as part of your tax return.
