What to check when an internet promotion ends

By the ComparaUno editorial team · Published on 8 October 2026.

Find the exact date

Check which month the discount ends and whether other benefits such as platforms or equipment end too. An invoice number and signup month may not reconstruct a promotion; use the sales confirmation and billing detail.

Separate price changes from extras

A higher bill may include extra services or charges other than the monthly price. Identify the plan price and optional or one-off charges before comparing. Ask the provider to explain differences.

Calculate future spending

Evalúa el gasto de los próximos 12 meses usando las tarifas que correspondan a cada tramo. No extiendas tu precio promocional actual a todo el período si sabes que termina antes. Tampoco compares el primer mes de otra oferta con tu gasto anual.

Confirm any new offer

Request price, duration, subsequent price, terms and equipment. Save confirmation before accepting. If the offer is incomplete, leave the calculation pending; assumed figures may suggest savings that never materialise.

Before accepting a new promotion

Review your exact offer

Compare your bill with the promotional period and charged items. An offer for new customers may not apply to your current contract.

Compare the following year

Ask for each option’s duration and later rate. If switching providers, confirm availability and scheduling before cancelling your current service.
