Prepaid vs. Postpaid in Germany — Full Comparison
The choice between a prepaid and a postpaid mobile plan is one of the most fundamental decisions when selecting a German tariff. Both models are widely available in Germany through all major operators, and both have distinct advantages and limitations. This page provides a structured comparison across all relevant dimensions.
Definitions
Prepaid (Prepaid-Karte, Guthabenkarte): A model where the user loads credit onto a SIM card before use. No invoices are issued and no contract is signed. The SIM remains active as long as minimum top-up requirements are met.
Postpaid (Laufzeitvertrag, Mobilfunkvertrag): A model where services are consumed throughout the month and billed retroactively. A formal contract is signed with a defined minimum term.
Cost Structure
Prepaid Costs
- SIM card: Usually free or up to €10. Often available at supermarkets, electronics stores, or online.
- Activation credit: Some providers require an initial top-up of €5–€15 to activate the card.
- PAYG rates: Calls typically cost €0.09–€0.29/min; SMS €0.09–€0.19 each; data €0.01–€0.24/MB depending on provider.
- Monthly packages: Range from €3–€30/month for bundles including data, calls, and SMS.
- No base monthly fee is charged if no package is active.
Postpaid Costs
- Base monthly fee: Ranges from roughly €8/month (budget MVNOs) to €60+/month (premium MNO plans with large data and 5G).
- Activation fee (Anschlussgebühr): Typically €0–€40, often waived during promotions.
- SIM card fee: Usually included or €10 maximum.
- Hardware: Subsidized device may add €0–€10/month to the total depending on model.
- Overage charges are uncommon in modern tariffs; throttling replaces them for data.
Commitment and Flexibility
Prepaid has no contractual commitment. The user can stop using the SIM, switch to a different provider, or simply let the balance expire without penalty. This makes prepaid ideal for users who want full flexibility — tourists, short-term residents, or those uncertain about their usage needs.
Postpaid contracts in Germany typically run for 24 months. Early termination is not a standard right; the consumer must pay the remaining monthly fees unless the provider agrees to an early exit. However, as of 2022, the revised Telekommunikationsgesetz (TKG) introduced the right to cancel with one month's notice if the provider materially changes contract terms. Month-to-month postpaid contracts (monatlich kündbar) are available but usually 20–40% more expensive per month than 24-month equivalents.
Top-Up Methods (Prepaid)
Prepaid top-ups (Aufladungen) in Germany can be performed through multiple channels:
- Provider website or app (credit or debit card, PayPal, SEPA direct debit)
- Supermarkets (REWE, Edeka, Aldi, Lidl, Netto — at checkout or service terminals)
- Post offices (Deutsche Post / DHL service points)
- Prepaid vouchers (Aufladegutscheine) sold at petrol stations and electronics stores
- Automated top-up via SEPA direct debit when balance drops below a threshold
- SMS top-up codes (Aufladecode) from online voucher vendors
For detailed instructions on each method, see the How to Top Up Prepaid guide.
Identity and Registration
Both prepaid and postpaid require identity verification in Germany under §111 TKG (Telekommunikationsgesetz). For prepaid, the SIM cannot be activated until identity is confirmed. Methods include:
- In-store purchase with ID presentation
- PostIdent procedure (present passport or ID at any Deutsche Post branch)
- VideoIdent (video call with an agent, usually within minutes)
- eID (electronic ID chip on German ID cards via the AusweisApp)
Postpaid contracts additionally require a German bank account (for direct debit) and a German mailing address. A Schufa credit check is standard for postpaid subscriptions.
Data Access and Speeds
Both prepaid and postpaid plans can offer LTE and 5G access, but maximum available speeds often differ. Premium postpaid plans from the MNOs (Telekom, Vodafone, o2) typically provide the highest data caps and priority access during network congestion. Prepaid and MVNO tariffs sometimes restrict maximum speeds even before the data cap is reached — for example, limiting LTE speeds to 25 Mbit/s rather than the full network speed.
Roaming Differences
Under EU Roaming Regulation, both prepaid and postpaid SIMs must allow roaming within the EU/EEA at domestic rates, subject to fair-use policies. However, some prepaid SIMs — particularly very budget-oriented packages — may disable EU roaming by default or apply additional conditions. Always verify the roaming terms in the product description before travelling. See Roaming in the EU for full details.
Comparison Table
| Factor | Prepaid | Postpaid |
|---|---|---|
| Contract term | None | Typically 24 months |
| Credit check | No | Yes (Schufa) |
| Monthly invoice | No | Yes |
| Cancellation | Instant (no notice) | 3 months notice (standard) |
| Hardware subsidy | Not available | Available |
| Roaming (EU) | Available (verify terms) | Standard inclusion |
| SIM activation | After ID verification | After contract signing |
| Auto-renewal risk | None | Yes (if not cancelled in time) |
| Overspend risk | Limited by balance | Possible if extras used |
| Best for | Flexibility seekers, low usage | Regular users, device buyers |
Who Should Choose Which
Choose prepaid if: You want no commitment, you use your phone infrequently, you are a tourist or temporary resident, you have no German credit history, or you are testing a new network before committing.
Choose postpaid if: You are a regular user needing consistent data volumes, you want to buy a subsidized smartphone, you require predictable monthly billing, or you need access to the highest 5G speeds and data caps.
Hybrid approach: Some consumers maintain a postpaid tariff for their primary SIM and use a prepaid SIM in a second device (tablet, smart watch, or data-only SIM) for occasional use.
