Why am I not receiving SMS notifications when I make an online banking transaction?

Please wait a moment, sometimes it can take a few minutes for the SMS key to sign.
If you are still having problems, you can contact your phone operator to perform some additional checks and configure your SIM card correctly.
You can also carry out the following checks:

• That the handset is not in "do not disturb" or similar mode.
• That there is space to receive SMS. You can delete old SMS.
• That you have good coverage and that you do not have roaming activated, as the operators themselves do not ensure SMS delivery in these conditions.
• There are terminals that allow you to mark certain numbers as unwanted or applications that block calls or SMS because they consider them unwanted.
