In Thailand, as in Poland, we have several mobile network operators to choose from. Which one to choose and what package?
There are SIM cards to choose from, and eSIM cards – if your phone supports them (and there are quite a few, you may not even know it). An eSIM card is certainly more convenient with a regular card, and it's good to have a dualSIM (the ability to add 2 sim cards to the phone).
We can also replace the Polish SIM card with a Thai one. It will also give us a guarantee that we will not be charged additional fees (Remember to turn off roaming before departure, otherwise the phone on exit from airplane mode may immediately start downloading data).
I chose a regular SIM card for 199 baht, for 30 days (about $23). That's how long my stay lasted, too, but the card can be renewed.
Landing in Bangkok, we will get it at the 7/11 store, which is located on the second floor on the left (coming out of the arrivals hall). Enter the second floor and head to the very end.
The cards are on the right (visible in the photo on the refrigerator at the entrance). It is important to remember that the number of these cards is limited, so sometimes it is worth a quicker step after landing there 🙂
SIM card purchase
On this 7/11, card payments are from 200 baht, so if you want to pay that way (and usually when landing at the airport we don't have the money listed yet) it's worth adding something to drink, or a snack to your cart 🙂
When you purchase a SIM card, you will be asked for your passport, and your photo will be taken.
And that's it, the card is ready for use.
Tourist SIM Cards
In the arrivals hall immediately after the exit, there are stands of operators with tourist cards. They are more expensive than “local” ones.
I haven't used it, but currently the best deal you can try to search through mobimatter.com
