Mobile Phone Plans in Argentina: What British Expats Need to Know

Getting mobile data in your first days in Buenos Aires used to require hunting for a phone shop and navigating Spanish bureaucracy. It's now much simpler.

Before you arrive: eSIM

If your phone supports eSIM, buy an Argentine eSIM before you land. Services like Airalo, Holafly, and Nomad all offer Argentina eSIM plans. You pay in advance (typically USD 10-20 for 7-10GB over 15-30 days) and activate on arrival.

This is the easiest solution for the first two to four weeks while you get settled.

Getting a local prepaid SIM

Once you're in Buenos Aires, walk into any Claro, Personal, or Movistar store with your passport. You don't need a DNI for a prepaid SIM. Pick up a SIM, load credit (recargar) at any kiosk or through the provider's app, and you're connected.

The three networks:

• Claro: Generally the best coverage in Buenos Aires and regionally. Recommended by most expats.
• Personal: Good urban coverage, slightly less consistent in rural areas.
• Movistar: The Telefónica brand. Coverage is comparable to Personal.

For Buenos Aires city life, all three work well. If you travel frequently outside BA, Claro has the edge.

Prepaid plans (planes prepago)

Providers offer monthly prepaid packages with data, calls, and texts — you load a set amount and the plan activates. Expect to pay the peso equivalent of USD 5-15 per month for a basic data plan. Prices change frequently with inflation, so check the current app or ask in-store.

Moving to a postpaid contract

Once you have your DNI and an Argentine bank account, you can get a postpaid plan. This is cheaper per gigabyte and includes direct debit billing. Monthly plans with reasonable data: ARS 5,000-15,000 depending on data allowance.

Keeping your UK number

Most British expats want to keep a UK number active for family contact, two-factor authentication on UK services, and professional continuity.

Options:

• Giffgaff: Low-cost UK MVNO with a good £0/month SIM plan (top up when needed, number stays active)
• Smarty: Similarly affordable
• Lebara: Good international rates

Put your UK SIM in an old phone or a secondary eSIM slot. Top up every few months to keep the number alive.

WhatsApp as the communication backbone

Buenos Aires runs on WhatsApp. Nearly all Argentine communication — social, professional, school — happens there. Once you have any working data connection, WhatsApp is where Argentine life takes place.
