MobileID returns "Problems sending SMS", when trying to login to a service such as a VPN. What could be wrong?

This error suggests that MobileID was unable to submit SMS to an end user.
A common reason for this would be a network connectivity failure in between MobileID server and the remote SMS gateway(s) -- for example a firewall rule change that would block MobileID from binding to a remote SMS gateway.
To verify a connectivity failure:
If bind fails due to a reason other than the timeout, check your SMS gateway account validity:
SMS gateway may consider you rebind as a duplicate. This can occur on a SMS gateway that allows only one concurrent bind per MobileID server.
This is the case for example for Tectia MobileID SMS Hub services.
This situation can occur for example due to a temporary network failure, i.e. due to a firewall reboot, where the SMS gateway connection dies, causing MobileID to automatically rebind a new connection.
However, the remote SMS gateway may detect this only after a delay, i.e. 10 minutes and in meanwhile block all subsequent rebinds.
For this there exists no resolution, but to wait for SMS Gateway to eventually close the zombie connection and all the new rebind.
