Which brokerage is easiest to deal with when accessing the site/app from abroad?

I've seen people here talk about how you need to call Rakuten from abroad, getting calls from SBI or something annoying like that when you try to log in from outside Japan. Is there a platform that lets you log in from abroad without too much hassle?

I'm considering opening a taxable account at Rakuten and Nisa and Ideco at SBI but am open to other options. I will just buy global index funds, set and forget.
