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.

ID requiredNo ID needed for prepaid SIMs (the Netherlands has no prepaid registration law; mandatory registration was rejected in 2017 and 2019).

Physical SIMs can sign up without issues.

Carriers & prefixes

Mobile prefixes by carrier.

Number portability applies — a prefix only shows the original carrier. 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call or SMS for 3 months freezes the SIM (a top-up alone doesn’t count), and 1 month later the number is permanently withdrawn.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
