Carrier How does it work when I get an eSim when traveling?

[questionwonder]

I want to travel to Thailand, so when I arrive I'll get an eSim. How does it work?
I connect the eSim and now I can use that new number to make calls and texts.
What happens when I receive a call from my US number, do I see it coming through on my iPhone?
If I answer it, will I get charged from my US carrier?

If I make a call or send texts to the US will it use my eSim account number?

First off, get the eSim from home before you leave. Much easier. The eSim will act as a second line so you can keep using the original service while at home.

Yes, you get a new number presumably local to your destination, and can make calls and texts using it.

If your original home service works in the destination country, you will receive calls/texts there for your original number, but they may be expensive depending on what your US home carrier charges. Probably best not to answer them. Either forward the original number to your eSIM number, or check voicemail using the eSIM.

Texts and calls can be sent using which ever service you select at the time.

Do you think buying an eSim is better than buying a T-Mobile international package?

Regarding Thailand the easiest way is, just to get an eSIM in Thailand. At the airports there are shops from local providers specially for tourists. They even set it up for you there and off you go. Their eSIM include special data packages you can choose from when buying. All you have to do then, is to set your phone to use data from the new eSIM. Calls do work from and to both lines.

Personal experience in Thailand.

The international packages from T-Mobile are much more expensive and ususlly contain less data.
