Recently my Airtel Sim card was damaged and hence replaced with same number. I tried many times to log in using same registered mobile no. linked with my BOB account but everytime it says - unable to send text message (despite having Recharge of 249 Rs Airtel Prepaid Plan that allows 100 SMS, Unlimited calling and 1.5 GB internet daily) to get an access of my BOB account on this app. Don't know what's wrong with this app? It's really frustrating and annoying. Do help me in this matter ASAP.
