4G SIM Card (Siam Center or BKK Airport Pick Up) for Switzerland from AIS (Unlimited Data)

Very good to use for communication. And most importantly, it's very worthwhile. Makes you not miss contact and travel comfortably.

Sim ais can be used in many countries. The internet is fast and not stumbled at all. Can be used for a long time throughout the trip Slightly cheaper than buying in store buy through klook Show the voucher to the staff and exchange your SIM card. No need to wait in line Very convenient and fast

Exchange SIMs at Siam is very easy to exchange. There is no queue but when used in Switzerland it feels that the signal is not as good as the SIM card of the Swiss itself. Unlike 2fly in Japan, that one feels a lot faster than in Europe.

Buy a SIM card for the family to use in Switzerland. The signal is good, some is not good, it depends on the location, but overall, it's very OK. Very good after-sales service Will always recommend friends

Pick up at kool Siam Center, turn it on before going to use it well.

Exchange vouchers to the counter conveniently, quickly, insert the SIM and use it without any problems. Clear signal throughout the journey

Convenient both when buying and pick up the SIM The SIM is easy to use. No problem when using in Switzerland, inexpensive and with a discount.

Its a breeze to collect the card and most importantly the location is very accessible.
