First of all, you will need to speak to a real person if you want to activate their sim card. Don't think that the sim card will be activated by their automated process on the phone. Call them up and speak to someone.
Secondly, when you go to Dodo's website, eventually you find their Mobile Broadband settings listed as below.
However, all you really need to do is in the APN settings of your tablet or mobile, just add in dodolns1 (that's lowercase of DODOLNS1). You may need to add dodolns1 to APN Name as well. I made the mistake of thinking the l was actually I. Don't worry about anything else in the APN settings. Definitely don't worry about the Authentication protocol, Access Number or the silly SP code. Androids don't have these fields.
The mobile internet should then work. So did this help you? let me know.
