Compare SIM only
Already have a phone and only looking for a plan? With SIM only you don't pay for a device, so your monthly amount is lower. Compare SIM only plans here from providers such as Simyo, Odido, Vodafone, Ben and KPN. For each offer you see the data bundle, the calling minutes, the network quality and whether the plan is cancellable monthly. From around 5 euros per month.
How much data do you need?
Light use (calling, messaging, occasional internet) usually fits within 1 to 5 GB. Normal use with social media and some video calls for 10 to 25 GB. If several people stream or you use a lot of hotspot, choose an unlimited data bundle. A suitable bundle prevents you from paying unnecessarily or having to buy extra.
Cancellable monthly or fixed contract?
A monthly cancellable plan gives maximum flexibility: you can switch at any time. A fixed contract of 12 or 24 months is usually cheaper per month, but ties you down longer. Choose based on how certain you are of your choice.
Which network is best?
Most providers use the network of KPN, Odido or Vodafone. KPN is known for the widest national coverage, Odido is strong in urban areas. A cheap brand running on a strong network gives you the same coverage for a lower price.
