I am trying to transfer some bitcoin and I keep getting the message that I have 30 seconds to confirm a code via text/sms code, however I do not receive a text. I need some help urgently to fix this problem!
Probably the trouble is on the side of the service you are using, and exactly between the website and the mobile operator (it happens many times - They are not "compatible" with each other). The best solution is to contact the website support (probably they can "push" your transaction manually), or use another mobile.
