Getting a working local phone number is one of the first practical tasks after landing — you need it for everything from setting up a bank account to receiving verification codes, and most students end up doing it twice: once in a rush during the first chaotic week, and again a few months later once they've figured out what actually made sense. Knowing the landscape in advance — prepaid versus contract, what you'll be asked to prove, and the eSIM options that smooth over the gap before you're fully settled — can collapse that into one decision instead of two.
Prepaid vs. Postpaid (Contract) Plans
Prepaid plans are pay-as-you-go: you buy a set amount of data, calls, and texts upfront (often monthly, sometimes for shorter or longer periods) and top up when it runs out. There's no contract, no credit check, and generally minimal paperwork to sign up — which makes it the far more accessible option for someone who just arrived and has no local credit history yet. If you've read Gabble's guide on building credit abroad, the core issue is the same here: postpaid contracts are a form of credit (the carrier is extending you a month of service before you pay for it), and carriers typically want some evidence you're a reasonable credit risk before offering one without conditions.
Postpaid (contract) plans typically offer better rates per gigabyte and sometimes bundled device financing, but usually require a credit check, and new arrivals with no local credit history often get rejected outright or approved only with a security deposit — functionally similar to a secured credit card, where you pay upfront to offset the lack of a track record. Some carriers offer international-student-specific postpaid plans that waive the credit check requirement in exchange for proof of enrollment and, sometimes, a deposit — worth asking about directly, since these aren't always advertised prominently.
The practical starting point for most new arrivals: start on prepaid. It gets you connected immediately with minimal barriers, and you can always switch to postpaid later once you have a longer local track record, a bank account, and a clearer sense of which carrier actually has good coverage where you live and study.
What You'll Typically Need to Sign Up
Requirements vary by country and carrier, but commonly include some combination of:
- A valid passport or national ID, and in some countries proof of your visa or residence permit
- Proof of local address — a lease agreement, a university housing confirmation letter, or sometimes a recent utility bill
- A local bank account or card, required by some postpaid plans and occasionally even by certain prepaid options, though many prepaid plans can be paid for entirely in cash or by a foreign card
- Proof of enrollment, specifically for carriers offering discounted student plans
Requirements are generally lighter for prepaid than postpaid, which is a large part of why prepaid is the easier on-ramp — some prepaid SIMs in some countries can be bought with just a passport, or in a few cases with no ID at all, though regulations on this vary significantly (some countries mandate ID registration for any SIM, prepaid or not, as an anti-fraud or security measure).
Typical Costs — Rough Ranges, Not Promises
Phone plan pricing varies enormously by country, carrier, and how much data you actually use, and any specific number here will be somewhat dated by the time you read it. As a rough, approximate sense of the range international students commonly report:
| Plan Type | Rough Monthly Range (Indicative Only) | Notes |
|---|---|---|
| Basic prepaid (limited data) | Low — often in the single digits to low tens of a given currency's units | Fine for light use, wifi-dependent |
| Mid-tier prepaid/postpaid (moderate data) | Moderate | Most common choice for typical student use |
| Higher-tier postpaid (large/unlimited data, possibly bundled device) | Higher | Better value per GB, usually requires credit approval |
Budget carriers and mobile virtual network operators (MVNOs, which lease network capacity from major carriers and sell it cheaper) are frequently the best value option in a given country and are worth specifically researching rather than defaulting to the first major carrier store you walk past — coverage is usually identical or near-identical since they run on the same underlying network, but pricing can differ substantially.
eSIM Options for the Transition Period
Before you've settled on a permanent local plan — sometimes in the first days after arrival, before you even have a fixed address to prove — an eSIM (a digital SIM that doesn't require a physical card) from a travel-focused provider can bridge the gap. You typically buy a short-term data package before you even leave home, activate it on arrival (or sometimes as soon as you land, if the network's available), and have working data immediately without hunting for a physical SIM store in an unfamiliar city on day one.
This is particularly useful for the practical logistics of arrival: navigating to your accommodation, contacting your university, sorting out a local bank account or a permanent SIM, all of which are considerably easier with working data from the moment you land rather than relying entirely on airport wifi. Most eSIM travel providers offer data-only packages (no local phone number), which is fine for this bridging purpose but isn't a substitute for eventually getting a proper local number, since some local services (banking especially) may expect a local number specifically for verification.
Keep Your Home Number Active
This is the detail that catches a surprising number of students off guard after the initial move is done: don't cancel your home country phone plan the moment you get a local number. Your home number is often still needed for:
- One-time passcodes (OTPs) from home-country bank accounts, which many banks will only send to the number on file — an issue if you're still managing any home-country banking or payments during your studies
- Family and friends who default to messaging or calling your old number, especially over apps that aren't purely internet-based
- Verification for accounts tied to your home number — some services flag or lock accounts when the registered number suddenly becomes unreachable
The easiest way to keep this working without paying for a full plan you're not using is switching your home number to the cheapest possible maintenance plan (many carriers offer a minimal-cost "keep the number active" option) or porting it to a service that keeps a number alive for receiving texts and calls at low or no cost. Losing access to that number can complicate re-verifying bank accounts and other services in ways that are considerably more annoying to fix after the fact than to simply avoid.
A Reasonable Sequence
- Before departure: Consider a short-term travel eSIM for data on arrival, if your budget allows it.
- Before canceling anything at home: Set your home number to a low-cost maintenance plan rather than canceling outright.
- First one to two weeks: Get a local prepaid SIM using your passport and whatever address proof you can provide (temporary housing is often fine initially).
- After you're settled (bank account open, permanent address confirmed): Reassess whether a postpaid plan makes sense, now that you can actually qualify for better rates.
Getting this sequence roughly right avoids both the day-one problem (no way to get online or make calls) and the month-three problem (locked out of a home bank account because the OTP went to a number you already canceled).
