For many intrepid travellers staying in contact with the outside world is a hidden pleasure. No one really wants to admit how dependent we are on our mobile phones and that wonderful thing called the internet and it’s friend social media. Who doesn’t want to share a million photos of the amazing adventure that you are having? If you don’t Instagram that beach sunset did it even happen?

Despite us living in such a wonderful advanced world when it comes to our mobile phones and data connection contracts for roaming we really are stuck in the dark ages. Too many companies charge crazy high fees. For instance, our service provider charges up to $5 a minute per phone call and a minimum of $3 per MB. Crazy huh? So to avoid our phone bill bankrupting us we like to purchase local sim cards along the way. Now usually this is really easy. Just like that time in Lima. However, on our recent adventures traveling down the west coast of South America we discovered that not all countries are so simple.

How to buy a prepaid sim card when traveling in South America?

Before we start there is a grand assumption that you have an unlocked phone. One that is not restricted by your service provider. Thankfully these days it’s becoming less and less common to have a phone locked to a single network. If you’re unsure you’ll need to contact your service provider before leaving home.

The first thing you need to have on you is cash and your passport. The majority of countries we are going to discuss, Chile, Argentina, Bolivia, Peru and Uruguay will have options for a free sim card and a paid sim card. On average if you have to pay for a sim card the cost is around 5-20 pesos. Which works on to be around $1 at most.

Some countries and companies will want you to register the sim card and to do so you will need your passport.

Argentina

One of the more pleasant and simpler things in Argentina was buying a sim card. We had a Tuenti and a Claro sim card. Tuenti is a new company that was launched in Salta when we were there. Sadly there was no where outside of Salta to buy credit for our Tuenti card. The Claro card we bought from a kiosk but had to go into a Claro store with our passport to have it activated.

  • Passport needed if buying from a store
  • Cost 40 peso


Bolivia

We bought Entel simcards in La Paz. It was as easy as walking into a kiosk style store and asking for a prepaid sim card. The staff will put the sim card in a store phone and activate the card for you. All in all this took around 10 minutes, including additional credit. Don’t be surprised at the lack of internet speed in Bolivia. It’s just not great but is enough to Insta your coffee and cake experience.

  • No passport needed.
  • Cost 40 Bob approx $6 USD
  • 10 minutes set up time

Chile

Ok so Chile used to be super easy to buy a sim card. Now it is not. I repeat – it is not. Since September 2017 the Chilean government decided that all foreign phones must be registered in Chile. Sounds simple right? Ah not at all. To get your phone registered you need to go to an authorized store. Which at the time of writing there are 12 but only in Santiago. You also need to have a Chilean phone number. But you can’t get that until your phone is registered. It’s a bit of a chicken before the egg scenario. Which we couldn’t figure our way around.

We did buy a WOM sim card from a kiosk. It worked on and off for a few days. Most of the time our phones were blocked. Unless you are going to be in Chile for months on end I wouldn’t suggest bother trying to get a sim card and your phone registered. The process is still new and the options are very limited. In fact I would suggest that you are better off buying a cheap phone in Chile and using that as a wifi hotspot.

Peru

Now by far the easiest country to buy a sim card in was Peru. We arrived in Lima from Australia (via New Zealand and Buenos Aires) so it made sense to get ourselves connected in Peru. We opted for a Claro sim card. For less than $20 we got two sim cards complete with data. To help you more here’s our complete guide on how to buy a sim card in Lima.

Uruguay

By far my favorite country in South America. Uruguay had some of the best wifi on offer, so in all honesty you probably don’t need to worry too much about getting a sim card here. However, if you do need a sim card it is relatively easy. Claro operates in Uruguay and many hostels have free sim cards available. You will need to have some pretty amazing Spanish skills as you need to call a number to activate the service. The easiest way to do this is to ask for assistance from your hostel staff.

If you aren’t staying in a hostel then you can go into a store, complete with passport and get an activated sim card.

How to recharge your prepaid service

No matter where you are in South America the recharge process is the same. On the streets, there are plenty of kiosks that sell newspapers and magazines. This is where you need to go. You will need cash and your phone number. All you need to do is ask for a recharge, the amount you want to pay and the company. The staff member will ask for your phone number and do the rest. Depending on who you go to you might receive a voucher that you need to text. Most of the time though this is done for you and you’ll receive a text from your service provider advising that you have recharged your account.

Do the sim cards work across countries?

Ah yes and no. More no than yes. You’ll soon notice that the same companies are operating in different countries. Which would make it wonderful if you could just buy one sim card and use it along your adventures. Sadly it doesn’t quite work that way. Each company has a different branch in each country. These services don’t talk to one another.

Just remember that it is South America. Things don’t always work how we expect them to and a lot of the time you might not be in an area that has mobile phone service. It’s all apart of the adventure.

  2. Oh this is super useful! Although I have an amazing network in Australia where all I have to do is turn on my mobile data and I get charged $5 each day and it uses my contracted data. So I don’t need ot buy a sim, change phone numbers or buy more data. It doens’t cover all countries but most of them are on the list. So handy!

  3. This is an incredibly informative post. I normally don’t use SIM cards when I travel as most of my travels have been short term and I rely on wifi to connect
    But it’s great information
    Thanks for sharing

  4. Entel Peru has a special tourist SIM card but it’s quite expensive (US$ 20). For Peru, I’d recommend Claro (Av. José Larco in Miraflores/Lima, close to Calle Schell). As a resident, I have a “cobertura sin fronteras” plan which works in almost all Latin American countries (but you get less minutes and megas abroad). However, it’s post-pago and probably not available for tourist. Bitel is quite new in Peru and currently the best option for data.

  6. Anybody with info on Peru?

  7. Hi Jean! thank you so much for the info. My cell phone provider is charging us about $65 dollars/month during our 8month trip through mexico, central, and south america for our regular plan and phone we use in the US. they will only charge us $5/day on the days we use any call/txt/data. Do you think this is worth it to keep? or should we scrap this plan and use sim cards in every country?(in other words, just about how inexpensive is it to use sim cards?)

    • Hi Juan,

      It’s so cheap! I’d be ditching your plan for now and going local where you can.

  8. Do the minutes/Mb expire? If I enter a country for say 2 months, and load up a bunch of time (assume more than I’ll use) will it be valid for that entire time?
    Also, do you get a new phone number with each new SIM card or can you continue using the same number (like your original cell phone number)?
    Thanks!!

    • Hi Chris,

      Yes it the minutes do expire. But it’s so seriously cheap to recharge. I only ever used the data. Didn’t need to make any calls. As I was buying a new service with the sim card I got a new number each time. But with apps like WhatsApp and Facebook Messenger, it was easy for people to still contact me. Hope that helps xx
