People who don’t want to go into a bank or ATM to do their banking:  If you’re busy, on the go, or just not that comfortable with traditional banks and ATMs, mobile-only banks might be your best option. The biggest drawback is that you won’t have any access to tellers and branch locations—so if you have questions about your account, you won't be able to talk with an actual person face-to-face.
People who don’t use banks often: If you only need checking and savings accounts occasionally—for example, for paying bills online—mobile-only banks can save you money on monthly fees because they charge lower rates than traditional banks for people with low balances.
People who want to save money on fees:  If you don’t need access to a branch or teller, mobile-only banks can be less expensive than traditional banks—especially if you have a low balance and don’t use your account often.
People who are comfortable with technology: If you're comfortable using online banking and other digital tools, mobile-only banks might be a good fit for you because they're designed around those tools and make it easy to do everything from managing your accounts to paying bills online.
People who want more control over their finances: If you like to track your spending, mobile-only banks can be a good option because they make it easy to see and manage your accounts online or through a mobile app.
Young people with limited income or credit history who can’t get approved for traditional accounts:  If you don't have a lot of money to deposit in an account, and you don't have a long credit history, mobile-only banks are a good option because they often don't require any minimum balance or credit check.
Travellers with temporary visas that don’t allow them to open traditional bank accounts in other countries (especially useful if you travel often):  If you're on a visa and can't get a traditional bank account, mobile-only banks are an option for managing your money while travelling.
