Mobile telephones

Dutch mobile telephone numbers always start with 06. If you would like to have your own mobile telephone number, choose a telephone provider, subscription type or prepaid cards. The website gives an independent overview of rates, offers and providers. Please note that you will need a proof of address before subscribing to a mobile telephone provider. At belhuizen, best described as phone houses, you can buy phone cards for international calls, which offer convenience but not always the lowest rates. You can find belhuizen in almost every city in the Netherlands. Just ask around.

You can buy a SIM card at one of the outlets in the city. Telephone boxes are located at airports and railway stations and require phone cards, which you can buy at post offices, railway stations and some newsagents.You may also consider installing (free) 'telephone over the internet' applications like Skype, before leaving for Delft.
