With these global providers (the same (e)SIM for multiple countries), do they come with fixed local mobile numbers? In other words, e.g. if I go to Singapore today, can I give the local operators a +65-xx_xx_xx number as my contact number, and then when continuing to Japan, I could give out a +81 number? Even better, if the number is retained so that next time I go over I could give the very same local numbers again.
