What should I do if the SMS code of steam mobile phone token does not match the expectation?

The solution to the inconsistency between the SMS code of steam mobile phone token and the expected one is as follows:

1. First, restarting the phone can solve the synchronization problem.

2. Secondly, in the Steam account settings, disable and then re-enable the mobile phone token function.

Finally, none of the above methods can solve the problem. The best way is to contact Steam's customer support team. "They" can provide more specific help and need to verify their identities to solve the problem.
