Scenario: We have integrated msg91 with Leadsquared to send sms. Though we have enough credits in msg91, LS throws an error that we are short of credits while trying to send sms. PFA screenshot.
Reason: The issue arises when we don't add SMS credits (We don't generate any bill for adding SMS credits and this is done only to trigger SMS message to MSG-91) in leadSquared account.
Solution: After adding SMS credits to the desired leadSquared account. One will be able to send SMS from his/her login.
