Best Local Prepaid SIM Cards Worldwide (Lookup Tool)

What are the best local prepaid SIM cards in every country worldwide?

That, of course, depends on the country.

Let's talk about Digicel – a mobile operator active in the Caribbean, Central America & (Pacific) Oceania.

In most English-speaking nations in the Caribbean, it is the best.

However, that cannot always be said about Central America or Oceania – even though it is all by the same company.

So it can be a challenge to determine which SIM card is the best in country B, even if you had an amazing experience in country A with a SIM card from the same company (Digicel for this example).

Luckily for you, I am crazy enough to buy every SIM card available in the countries I visit so that you do not have to.

Based on my research, testing & findings, I can tell you which SIM card is the best without you wasting your money or being disappointed because you accidentally bought the worst SIM card available.

Instead, I am the one wasting my money 🤪.

That is why you are always free to buy me a coffee (or tea), which does not get spent on tea but on SIM cards instead (I do not get them for free, unfortunately).

Adu's collection of local prepaid SIM cards in 2020
Just a bunch of local SIM cards I have – and I have many more!

While I have in-depth SIM card buying guides, you may want to get a quick overview of the options in the country you are visiting.

That is what this page is for – and the lookup tool.

Here, you can easily see the best SIM card(s) in every country with the cost of a basic SIM card (so it excludes data-only and tourist SIM cards), and how much 1 GB of data will cost you.

Be sure to check the notes in the last column for additional information applicable to the country.

TIP: use this tool combined with the SIM card prices worldwide lookup tool.

For up-to-date currency exchange rates (let's say Euro to US Dollars), use the Wise Currency Converter tool.

For convenience, I will also list the best SIM card of each country below.

Sometimes, there is a cheaper option or an option that may be better for your purpose (let's say better coverage or speed than the one mentioned in the table below).

Therefore, you should use the lookup tool above for more information.

If you are confused about all the symbols, those are the currency symbols.

For up-to-date currency exchange rates (let's say Euro to US Dollars), use the Wise Currency Converter tool.

(Note – I update multiple individual country guides every week, but this page and the tool get updated every now and then. Click on the country name to read the SIM card buying guide of that country and for up-to-date information)
