SIM Card, Transport Card and Utilities: Setting Up Life Admin in Your First 72 Hours Abroad

Why order matters

You cannot do much without data or a way to move around the city, and every hour spent figuring out logistics with no phone signal is an hour lost. Set up connectivity and transport before you tackle anything else in your first three days.

1. SIM card or eSIM

Buy a prepaid SIM at the airport, a convenience store, or a phone shop close to your accommodation. Bring your passport, since most countries require ID to register a SIM. If your phone supports eSIM, some providers let you activate a plan online before you fly, so you land already connected.

Compare prepaid plans by data allowance rather than call minutes, since most of your communication with family and friends runs through messaging apps over data. A short-term prepaid plan for your first month works well while you decide on a longer contract once you have a local bank account or address proof, some contract plans require both.

2. Transit card

Cities with metro, bus or tram networks almost always sell a reloadable card at stations, airports or convenience stores. Buying one on day one saves money compared to single paper tickets, and many networks offer a flat cheaper fare or daily and weekly fare caps only to card holders. Ask your university or student union whether a student discount applies to your transit card, since many cities offer reduced fares with a valid student ID.

Examples across common destinations

London uses the Oyster card or a contactless bank card on the Underground and buses. Tokyo and most of Japan use Suica or Pasmo, which also work as small-value payment cards in convenience stores. Singapore uses EZ-Link or a contactless card on the MRT and buses. Seoul uses the T-money card, and Kuala Lumpur uses the Touch 'n Go card. Check which system your destination city uses before you arrive, most airports sell the local card at arrivals.

3. Utilities and internet

Check your housing contract before doing anything. University dorms and much purpose-built student accommodation include electricity, water, heating and internet in the rent. Private rentals often do not, and you may need to set up accounts with a utility provider and pay a deposit.

If you need to set up internet yourself, ask your landlord or letting agent which providers serve the building, since not every provider covers every address. A mobile hotspot from your SIM plan covers you for the days before home internet is installed.

What cannot wait past the first weekend

• A working SIM or eSIM, you need this for maps, verification codes and contacting your university

• A way to pay for transport, either a transit card or a mobile payment method your city accepts

• Confirmation of what your housing contract already includes, so you do not pay twice for utilities

• Your university's emergency and international office contact numbers saved in your phone

Common mistakes to avoid

• Signing a long SIM contract before you know your address, some providers need proof of address for postpaid plans

• Buying single transport tickets all week instead of a reloadable card, this adds up fast

• Assuming utilities are included without checking the contract, then getting a bill you did not budget for

• Waiting until Monday to sort out connectivity, when shops and offices open through the weekend in most cities
