Also, it's a good idea to see if BitMart has any service interruptions or repair notices that could affect SMS services.
If these steps don't fix the problem, you might want to try a different two-factor authentication (2FA) method, like Google Authenticator, which can send codes more reliably.
BitMart's support pages have step-by-step directions on how to connect Google Authenticator to your BitMart account.
If problems keep happening, you need to contact BitMart's customer service right away. In order to get help, you can use their Help Center or email them at [email protected]. Giving specifics about your problem will help speed up the settlement process.
