Automated Registration Page Input -- 2

I have a spreadsheet/csv/notepad with data that needs to be input into a registration page. This process cannot be fully automated. After inputting a mobile number on the first page a sms is sent by the site to my mobile phone with the security code. We have to manually input a security code.(This we want to do into the spreadsheet and then the software continues) This is the link to the website [login to view URL] The registration is 2 stages Stage 1 input mobile number - an sms is sent by the website with a security code which needs to be input for the registration page to be opened. Our data entry staff has 10 phones with the sims in to receive the security code and then inputs these into spreadsheet ready for stage 2. Stage 2. input all data requires for the registration page using spreadsheet. Name , Date of birth, email, password, pin, • Step 1 means we cannot automate, as someone has to input the data manually, but we are happy to do this • I need Something like program enters mobile numbers and sleeps for 5 mins and then look for sms code enters registration details • we want to be able to multiple registrations at a time • either by different tabs or browsers • so maybe 5-10 in 1 go • We have 300 records daily to input which is genuine data and genuine registrations • i have been told that this is tightly coupled with session of window..mean to say request has to be submitted from same window...even if you copy URL in another window this is taking you back to "Enter Mobile" screen • The software needs to be in desktop version so we can use this ourselves. we have an example of what we developed though this no longer works properly as the registration process has changed slightly.
