very bad connection and provider services , I complained about my issues a few times for softbank. But they are always skipping with my complaint. Only the focus is outstanding, I have got the Unlimited data connection plan but using only below 150 GB per month. But I can't get the WhatsApp call from here, this phone and SIM card issued by them, very poor signal strength and I am living in the City Area in Ehime Ken.
