How to read a number

+31612345678

+31Country code
Netherlands.
6Mobile prefix
Written 06 domestically — 0 is the trunk prefix, dropped when dialling from abroad. All Dutch mobile numbers start 06.
12345678Remaining 8 digits
Subscriber number. ACM allows 06 only for mobile telephony; data-only and M2M use 097 numbers — worth checking you aren’t given a 097 number for sign-ups.

Domestic format: 06 1234 5678 — 10 digits including the leading 0. Numbers are allocated to operators in blocks but can be ported, so a number doesn’t reveal its current operator; ACM’s number lookup shows which provider holds it.

Carriers & prefixes

Mobile prefixes by carrier.

Number portability applies — a prefix only shows the original carrier.

Porting rules in full

ACM: you can take your number to another operator and the old operator may not charge for it (an early-termination fee for the contract itself is separate); the new operator arranges it, usually within a few business days.

SIM cards & keeping a number

No ID is needed to buy a prepaid SIM in the Netherlands: there is no prepaid registration law. The government rejected mandatory registration in 2017 and 2019 and said in 2022 it would look again; no legislation was found as of the check date.

Keeping a number means using it regularly. The widely quoted “frozen after 6 months, then 90 more days” is an old rule from around 2015. Lebara’s terms say: top up, call, text or use data at least once every 90 days, otherwise credit freezes, and 30 days later the number is cancelled. Lyca Mobile is stricter: no outgoing call or SMS for 3 months freezes the SIM (a top-up alone doesn’t count), and 1 month later the number is permanently withdrawn. Both run on KPN.

Lebara Netherlands

Number-keeping SIM
Network
MVNO on KPN
Price
SIM price varies; credit stays valid as long as you keep using the line
Keeping the number
Lebara terms art. 27.3: after the first top-up, top up, call, text or use data at least once every 90 days. After 90 days credit freezes (incoming calls only); if you don’t top up within the next 30 days, credit and number expire and the SIM stops working. Lebara may change this with one month’s notice
ID check
No ID needed (no prepaid registration in the Netherlands)
SMS & calls
A normal Dutch number. Receiving SMS in China is free, sending costs €0.15 (per Holafly’s May 2026 summary of Lebara prepaid rates; Lebara’s rate finder couldn’t be read directly). Out-of-bundle spending outside the EU is capped at €50

Pros

  • KPN network
  • No ID needed
  • SMS and data both count as usage — easy to keep

Watch out

  • 90 + 30 days — much shorter than the “6 months” quoted online
  • The official terms are the June 2020 version; no newer text was found
