Do you need to buy a new phone when moving to Thailand, or can you use a local SIM card?

If your phone was provided as part of a plan with a carrier for a fixed term it will be locked and unable to use local SIM cards. If the contract is finished you can call to ask them if it's unlocked. It's a simple process. Thailand uses the same SIM cards and esims as most of the world.

American?

They sim’s AIS best

N!&&@ please

Thailand has no communication infrastructure.

It’s been a while since I brought a phone from the US, but here’s two thing to consider, is your phone unlocked from your US carrier (ATT, Sprint, T Mobile) and is it CDMA or GSM?

Where is this country located?

They only use 2 cans and a string

Why would you consider moving to a country before you know if they have SIM cards there?

Yea probably, they don't use tin cans and string like in US. Only a world class 5G network

This is a troll account they have been posting nonsense all week

If your phone isn't internationally unlocked, you will need to get it internationally unlocked (what I did, was about 20$, online, took 2 mins just had to plug my phone into a computer) or you can buy a new phone

Thailand has sim cards. If your phone is locked to a network you may need to get it unlocked or get a new phone.
