There are three mobile phone operators in Georgia, all of them offering SIM cards with data: Geocell; Beeline and Magti.
When looking at the 4G coverage in Georgia, Geocell is the weakest and Beeline and Magti are similar, however, the second one offers a bit better 4G network. Still, both of them cover most of the tourist areas in Georgia so either one should be good for you. You might also get a “free tourist SIM card”, they are often handed out at the airports. While the SIM card is free you, in fact, need to pay for the package and it’s not super cheap, it’s either 15 or 30 lari, depending on the package you choose.
It’s better to go to the mobile phone shop and buy the Georgian SIM card directly from them, with the package you actually need and for a better price.
What do you need to get a Georgian SIM card?
To get a Georgian SIM card you only need a passport and a working phone, so you will check right on the spot that everything works fine.
They need to write down some basic data from your passport, you need to sign the documents and that’s it, a few minutes later you can enjoy your mobile internet in Georgia.
