Usually, the confirmation code arrives within 30 seconds. However in some cases, your local telco may "throttle" the rate of messages they allow through their systems. When this happens, it may take up to several hours for the code to arrive.
Unfortunately, when this happens, all we can advise you to do is wait for the code to arrive. Please enter the code as soon as you receive it, because for reasons of security, codes do expire.
If you'd like to help us report these issues to our SMS provider, please send an email to firstname.lastname@example.org with the phone number you used to register for U.CASH, and the time you initiated the SMS verification request.
