Caller ID is from Myanmar. What is this for?

Calls from abroad are often fraudulent calls. Unless the number is an acquaintance, it is generally a sales promotion, advertisement or fraudulent call. Calls from foreign strange numbers are almost certainly fraudulent calls. The first language barrier and expensive telephone charges limit the possibility of making friends and chatting by international telephone, which is more a way for scammers to escape legal sanctions in China.

Another possibility is to make fraudulent phone calls through rebranding software and pseudo base stations in China. Neither of these situations will be a good thing.

I don't think it's Myanmar, because the phone bill in Myanmar is too expensive to lie to you.

If you can cheat money, you can't get it from Myanmar, so if you want to cheat you, do you have to be in China?

At least have a partner at home.
