Almost everywhere in the world, you can purchase a local SIM card at the airport (tourist fare, which tends to be more expensive than usual) or in the city at the official stores of the mobile operators. In the Tips section on our website, you can find what SIM card to choose for a particular country.
Be careful! Sometimes you may be offered to buy a SIM card on the streets without providing any documents. It might be a scam, so it's better not to take such a risk.
In some places, buying a SIM card is expensive (especially if you come for a short period), in some it isn't easy (in India for example). And what if your journey involves visiting several countries in a short period?
eSIM can be very convenient in that case.
But not every smartphone eSIM-enabled. Check in advance if your phone supports eSIM.
Additionally, it may cost more than a regular SIM card
If none of the above options suit you, then Wi-Fi is the most suitable choice.
BUT!
Not every place is willing to share their Wi-Fi password with non-customers.
In some places, you need to get a password to your local SIM card to have an opportunity to use Wi-Fi (yes, strange).
We recommend you install the Wi-Fi Map app, which can be very helpful in such situations.
It has a list and a map with Wi-Fi usernames and passwords. Every user can contribute, adding new passwords or places.
As a tourist, you can easily find the nearest place with Wi-Fi and use it to call your host or check reviews for a restaurant.
The app is available in both paid and free versions.
The free version works with the internet, so you need to find and save several networks in advance to use them while walking around without an internet connection.
The paid version requires a one-time payment and provides you with lifetime access. It also allows you to use the app without an internet connection
Additionally, they reward you with points for contributions, which you can later use to purchase eSIM.
