Esim or physical sim opinions.

I'll be visiting China for 30 days in May. I am considering buying a new phone with esim capability as my current phone doesn't have it.

As I understand the situation, an esim is much more convenient for bypassing the firewall and accessing apps such as whatsapp, also i can activate it as soon as i land which is obviously less stressful.

However, i have read from some sources that an esim is not so good for longer stays and if you're visiting rural areas. Then a physical sim recommended. Additionally, you can't register for some apps without a local number.

I'd like to avoid paying for both? Who thinks it is worth getting a new phone with esim capability just for this trip?

Thanks in advance.
