can i pay by electronic check instead of mailing in a physical check?

Yes. You can log-in to your account on MyAccount, call 1-800-CRICKET, or dial *729 (*PAY) from your Cricket phone and following the prompts make a one-time payment, or set up Automatic Bill Pay using your bank account information (i.e. electronic check). You should find this to be an easier and much faster experience than sending in a paper check, and it’s FREE!
