Text messages usually arrive within 5 to 10 seconds, depending on the country and the carrier.
If a message takes more than 30 seconds for delivery, there might be congestion in your carrier network.
The problem usually resolves automatically; just wait a bit and try to sign up later.
Some carriers in some countries block verification SMS, for example, Dubai. In such cases, should you not receive an SMS verification, you can proceed with creating the account regardless.
