I also have a smartphone with one SIM card, and I don’t want to change my number while traveling. This used to be a problem, but now I just use eSIM Taiwan. I activated it in advance, and the Internet started working immediately upon arrival, without changing the main SIM. It’s convenient – ​​my number remains available for calls and messages, and fast Internet is always at hand. No more searching for local operators or worrying about roaming. Everything works stably and without unnecessary hassle, which is especially important when traveling.

You can buy an eSIM data plan if your phone supports it. This way, you can keep your physical SIM for calls and use the eSIM for internet access.

By the way, when I went on a two-week trip to Japan, I chose Mobal sim card Japan  because they offer good rates. It turned out to be a great budget choice. The connection worked reliably, even when I was traveling to different cities of the country. I was happy with my choice.
