Getting a SIM Card and Phone Plan in Germany as a Student (2026)

Getting a SIM Card and Phone Plan in Germany as a Student (2026)
The moment you land in Germany, one of the first things you need is a German phone number — for bank verification codes, booking appointments, and reaching your landlord. Should you get a prepaid SIM (Prepaid) or sign a contract (Vertrag)? The answer depends on whether you already have an Anmeldung (address registration) and a German bank account.
This guide explains both models, the network operators and budget providers, the legal SIM registration, and a practical roadmap. Prices and data allowances change constantly — always check current offers before you buy.
📋 Overview at a Glance
| Aspect | Details |
|---|---|
| Two models | Prepaid vs Vertrag (contract) |
| Ideal on arrival | Prepaid — no commitment, just top up |
| Legal requirement | ID verification with passport at activation |
| eSIM | Widely available, quick activation, no physical card |
| Golden tip | Start with prepaid → switch to a contract later |

📱 Prepaid or Vertrag: Which Model?
Prepaid: you top up credit (aufladen) and use it as you go — no commitment, cancel anytime. It's ideal right when you arrive because you need neither a German bank account nor a credit history.
Vertrag (contract): a fixed monthly fee, usually with a 24-month term. The price per GB is cheaper and a phone is often included, but you typically need a German bank account for the SEPA direct debit — and sometimes a SCHUFA credit check.
| Criterion | Prepaid | Vertrag |
|---|---|---|
| Commitment | none | usually 24 months |
| Payment | top up in advance | monthly direct debit |
| Price/GB | higher | cheaper |
| German account needed | ❌ | ✅ (almost always) |
| SCHUFA possible | ❌ | ⚠️ sometimes |
| Best for | newcomers, short term | settled, long term |

📡 Network Operators & Budget Providers
Germany has three physical networks and many budget brands (Discounter) running on their infrastructure. A budget provider saves significantly if you don't need the fastest network.
| Provider | Runs on network | Trait |
|---|---|---|
| Telekom | Telekom | best coverage, premium price |
| Vodafone | Vodafone | wide coverage, mid-range |
| O2 / Telefónica | O2 | good value in cities |
| Aldi Talk | O2 | cheap, sold in Aldi stores |
| Lidl Connect | Vodafone | cheap, sold at Lidl |
| congstar | Telekom | Telekom network at a soft price |
| Lebara / Lycamobile | Vodafone/O2 | cheap international calls — popular with internationals |
> 💡 Tip: If you call Vietnam often, Lebara or Lycamobile usually have very cheap international plans. If you need stable reception on trains or in the countryside, consider the Telekom network (via congstar to save).
🪪 SIM Registration & ID Verification
Under German law, every SIM must be registered to a real identity. There are no anonymous SIMs. At activation you verify with your passport (Reisepass) via one of these methods:
- VideoIdent: a video call with staff, holding your passport up to the camera.
- PostIdent: taking your passport to a Deutsche Post branch for verification.
- In store: buy and activate in person, bring your passport.
The eSIM is increasingly popular: you scan a QR code and activate straight on your phone — no physical card, handy right after you land. The ID verification process still applies just as with a normal SIM.
🧭 The Smart Roadmap for Students
- Week one: Buy a prepaid SIM (or eSIM) so you instantly have a German number for OTP codes.
- Complete your Anmeldung and open a German bank account.
- Compare offers: Once settled, check whether a contract is cheaper for your data needs.
- Switch to a contract if it makes sense — watch the 24-month clause and how to cancel (Kündigung).
- Keep your number (Rufnummermitnahme): you have the right to port your old number to the new provider.
| Stage | Recommendation | Why |
|---|---|---|
| Newcomer | Prepaid / eSIM | no account needed, a number now |
| Anmeldung + account done | Consider Vertrag | cheaper for heavy data use |
| Frequent international calls | Lebara / Lyca | cheap international plans |
❓ Frequently Asked Questions
Do I need an Anmeldung to buy a SIM? Not strictly for prepaid — you only need your passport for ID verification. Most contracts, however, require a German address and bank account, so the Anmeldung helps a lot.
Does an eSIM work in Germany? Yes, the eSIM is widely available for both prepaid and contract. You activate it via a QR code, as long as your phone supports eSIM.
Which plan is cheapest for calling Vietnam? Lebara and Lycamobile usually have the best international plans. Compare the minutes to Vietnam in each plan, since offers change frequently.
Can I cancel a 24-month contract early? It's difficult and usually costs money. Read the minimum term (Mindestlaufzeit) and notice period (Kündigungsfrist) carefully before signing — which is exactly why starting with prepaid pays off.
