Phone plan discounts and deals: what to consider
Mobile phone providers are always offering incentives to new customers. However it's important to not get blinded by the initial discount, and to consider the longer-term implications of your phone plan purchase. Points to consider:
Discount length
Is the discount a one-off, or for the length of the plan? Many plans revert to their original price after the initial discount period meaning, in the long run, you could end up paying more than opting for a cheaper plan without an initial discount.
Data, calls and texts
Does the plan meet your needs in terms of its data, calls and text allowances? There's no point buying an expensive endless data plan if you rarely make use of your allowance. Or purchasing a cheap, limited plan that ends up costing you extra in top-up packs.
Check the small print
Mobile phone deals always come with Ts&Cs, and it's important to read them, as they could reveal hidden costs. Also make sure you're familiar with the conditions of your existing phone plan, as switching to another plan, even with the same provider, could incur penalties.
