How much do you pay for your phone?
GSMWEB is an independent website where you can compare telephone providers (GSM with ‘abonnement’ and ‘sim-only’s). Via this website you can find the best deals and also you can switch to a cheaper provider (you can keep your current number with ‘nummerbehoud’).
Check the website for the latest deals.
Please always check with your current provider if you are free to switch.
