Prepaid vs Contract SIM in Rome: Which One Should You Get?
Prepaid or postpaid contract? Documents, operators, number porting, and mistakes to avoid when activating a SIM card in Rome as a foreigner.
In a nutshell
In Italy you can choose between a prepaid SIM (you top up in advance, no monthly bills) and a postpaid contract plan (you pay at the end of the month, and you'll need an Italian bank account). For most people arriving in Rome, prepaid is the practical choice: activation takes a few minutes, requires no IBAN, and locks you into nothing. By law, every operator must verify your identity before activating any SIM — prepaid or contract, no exceptions.
At a glance
| Cost | SIM free or €5–15 activation fee. Prepaid plans from €5–15/month; contracts from €15–40/month. |
| Timeline | In-store activation: immediate. SIM by post or eSIM online: 24–48 hours. Number porting: 1 business day. |
| Where in Rome | TIM, Vodafone, WindTre, Iliad stores; licensed tobacconists and resellers; online with video ID verification. |
| Documents | Passport or national ID + Codice Fiscale (Italian tax ID). Non-EU nationals: also a residence permit or renewal receipt. |
Prepaid or contract: which is right for you
The main difference is how you pay. With a prepaid SIM you load credit in advance and draw from it: if it runs out, calls and data stop, but you'll never get a surprise bill. With a contract plan you pay at month's end via direct debit from an Italian current account, but you can bundle a phone in installments and often get more data for less money.
If you've just arrived in Italy, prepaid is almost always the smarter starting point: no IBAN needed, no binding contract, and you can switch operators whenever you want. A contract makes sense once you already have an Italian bank account, want a phone on installments, or are looking for a bundle that includes home fiber.
| Prepaid | Contract | |
|---|---|---|
| Bank account required | no | yes (Italian IBAN) |
| Minimum commitment | none | usually 24 months |
| Unexpected charges | impossible | possible (over-limit fees) |
| Phone in installments | no | yes |
| Average monthly cost | €5–15 | €15–40 |
| EU roaming included | yes | yes |
Documents you need to activate a SIM
DL 144/2005 requires every operator to identify buyers before activating any SIM, without exception. No ID, no SIM.
Italian and EU citizens: valid photo ID (national ID card, passport, or driving licence) plus Codice Fiscale (Italian tax ID — your personal 16-character alphanumeric code).
Non-EU nationals: valid passport plus at least one of the following: a valid Permesso di soggiorno (residence permit for non-EU citizens), the postal receipt from a permit-renewal kit, an asylum-seeker's permit, an EU long-term residence card, or an entry visa accompanied by proof that a permit application has been filed at the Questura (police headquarters — also the office that issues residence permits). You also need a Codice Fiscale; if you haven't received yours yet, some operators accept the Agenzia delle Entrate (Italy's tax-revenue agency) application receipt and issue a temporary code.
Minors: a parent or legal guardian must sign, presenting their own photo ID.
The main operators in Rome
Rome has both network operators — companies that own and run their own towers — and virtual operators (MVNOs) that lease capacity from the big networks. MVNOs often cost 30–50% less for the same signal quality.
Network operators (MNO): TIM, Vodafone, WindTre, Iliad, Fastweb Mobile. They have stores in every major neighbourhood. The most central Iliad Store is at Via del Corso 480; TIM and Vodafone have branches on Via del Tritone, Via Cola di Rienzo, and near Termini station.
Virtual operators (MVNO): Ho Mobile (Vodafone network), Kena Mobile (TIM network), Very Mobile (WindTre network), PosteMobile, CoopVoce, Spusu, and others. You can activate them online or at licensed tobacconists and resellers.
Sample plans, 2026 (always check each operator's website for current pricing):
| Operator | Cost/month | Minutes | Data |
|---|---|---|---|
| Iliad Giga 150 | €9.99 | unlimited | 150 GB |
| Ho Mobile | €9.99 | unlimited | 150 GB |
| Kena 9.99 | €9.99 | unlimited | 130 GB |
| Very Mobile | €5.99 | unlimited | 50 GB |
| TIM Power Iron | €12.99 | unlimited | 100 GB |
| Vodafone Silver | €9.99 | unlimited | 100 GB |
Three ways to activate your SIM
In-store is the simplest: walk in with your documents, pick a plan, the staff scans your ID and has you sign the identification form. The SIM is usually active immediately or within a few hours.
Online (physical SIM by post or eSIM): upload your documents on the operator's website, do a 30-second video-ID check where you hold up your document and read out a one-time code, then either receive the SIM by post in 24–48 hours or download a QR code for an eSIM. An eSIM is a virtual SIM with no physical chip — available from TIM, Vodafone, WindTre, Iliad, Ho, Kena, Fastweb, and PosteMobile — and it's the most convenient option if your phone supports it.
At a tobacconist or newsagent: some SIMs — Ho, Kena, PosteMobile, CoopVoce — can be bought at licensed outlets. The same ID rules apply: always bring your passport and Codice Fiscale.
Number porting: keep your number when you switch
If you already have an Italian number and want to change operator, you can take your number with you through mobile number portability (MNP). It's free by law (AGCOM Resolution 147/11/CIR) and takes at most one business day.
How it works: buy the new SIM from the new operator, give them your old number and the ICCID of your old SIM (the 19-digit serial printed on the back of the chip or on the original packaging), and sign the porting request. Your old SIM deactivates automatically. Any remaining credit on the old SIM is refunded by the old operator within 45 days on request.
One catch: if you're on a contract, porting doesn't automatically cancel it. You need to send a separate cancellation notice, with a maximum 30-day notice period (AGCOM Resolution 487/18/CONS).
Mistakes to avoid
- Buying a SIM from street vendors without proper ID verification. A SIM activated without official registration may be linked to someone else's identity and could drag you into legal trouble. Always buy from official stores or authorised resellers.
- Signing a contract without reading it. Some deals look like prepaid plans but are actually binding postpaid contracts. Read before you sign.
- Not cancelling your contract before leaving Italy. The plan keeps generating charges even if you stop using the SIM. Send a written cancellation with the required notice.
- Losing your SIM's PIN and PUK codes. Keep them somewhere safe and separate from the phone: you'll need the PUK if you enter the wrong PIN three times in a row.
- Buying "anonymous" SIMs. Anonymous SIMs don't exist legally in Italy. Buying or selling one is a criminal offence, and the buyer risks being drawn into an investigation.
Special cases
Applied for a Codice Fiscale but don't have it yet? Some operators accept the Agenzia delle Entrate application receipt and activate the SIM with a provisional code. Others require the final CF. Call ahead before heading to the store.
Asylum seeker? A prepaid SIM can be activated with an asylum-seeker's permit. Bring a photocopy of your home-country passport too if you have one.
No passport (e.g. holders of certain forms of international protection)? Some operators accept the Italian national ID card issued by the Comune (city hall / municipality). This varies by operator — check directly at the counter.
EU roaming: since 2017, you can use calls, texts, and data across the EU as if you were in Italy, with no extra charges, up to your plan's allowance (EU Regulation 531/2012). Outside the EU, the operator's standard international roaming rates apply.
