I bought it, but I never used it. Their virtual SIM card did not start on either the s21 or the s20.
The support can't say anything intelligible.
Don't get fooled.
The air conditioner is working, there are few people, they serve quickly. The problem: you take a SIM card for a month, and some jealous husbands call you at the number of the previous owner. Do they really have few numbers so that the numbers "lie" for at least half a year?
