Carriers & prefixes

Mobile prefixes by carrier.

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

Porting rules in full

Telecommunications Act § 59: users may port their number at any time, and since 1 December 2021 operators may not charge for it. So ranges only show who originally issued a number — after porting they say nothing about the current operator.

SIM cards & keeping a number

German prepaid SIMs require an identity check before activation under Section 172 of the Telecommunications Act (TKG § 172). Besides showing ID in person, Federal Network Agency (BNetzA) Decree 94/2021 allows video identification and eID; foreigners can use a passport.

The key keep-number rule is how long a line may go unused, and it differs a lot: Lebara counts time without chargeable activity, while Aldi Talk sets validity by the size of the last top-up.

Lebara Germany

Number-keeping SIM
Network
MVNO on Telefónica o2 (moved from Telekom in mid-2022)
Price
SIM and plan prices vary
Keeping the number
Per excerpts of Lebara’s 2025 terms: after 180 consecutive days without any chargeable activity (calls, SMS, data, top-ups or option bookings) service stops, followed by a 20-day transition with incoming calls and SMS only, and the contract ends on day 200. Cards registered before October 2025 may still follow the old rule: deactivation process after 90 days unused plus 20 days.
ID check
Identity check required before activation — video ident, eID, etc.; foreigners can use a passport
SMS & calls
China is in Lebara’s special roaming zone created in March 2025: outgoing calls €0.99/min, incoming €0.79/min; check SMS prices on the official site

Pros

  • New cards need use only once every six months

Watch out

  • Older cards may still be on the 90-day rule — check which terms apply
  • Incoming calls while roaming in China are charged

Depends on top-up
Keeping the number
Official: each top-up starts a new activity window whose length depends on the amount — €5 gives 4 months, €15 gives 12 months, €30 gives 24 months. After the window ends you stay reachable for 2 months; without a top-up the SIM is then deactivated.

SMS & calls
A normal German number; see the official site for roaming prices

Pros

  • A €30 top-up lasts two years, with clearly published rules

Watch out
