How to find the Yettle SIM card number in Serbia?
If you don't have money to call - send a "beacon" to the person whose number you know:
*321*phone number#call
For the most part, if my memory serves me right, not really. Only if you call someone so that person can tell you your number.
Actually, it is written on the card you have with the SIM card.
Finally, a truly working option! Thank you.
