Good morning) A couple of years ago I bought a Yota SIM card and I needed to change the number, after the change I sent the word balance to the number 900, and bam 13000 on the card! But there was less on my card, and then I realized that the card was not linked to mine. In general, if someone has access to Yota SIM cards, then, as they say, it's a matter of technology.
