Yes, you can. Many investors think that if they miss an SIP, then their account will be de-activated, but it does not happen. Even if you miss an SIP due to insufficient amount of balance in your account, then don’t worry you can just pay it next month, and your SIP will continue as normal. When you are starting with an SIP, don't think too much about the future. Even if you miss some of the SIP's due to financial crisis, it will be recovered in the next SIP.
