Maybe the dashboard he got did not have such an option. Even my unlocked zte modems default mblaze ui didnt have call option..my seller gave a zte application which has call sms net log etc .. Just depends on what you have,maybe he didnt get it out of the box.Hey bro..i'm from aynavaram..way too far
And btw try getting an updated dashboard (modem application) which your modem supports from the web. And bro,your number wouldnt have been activated immediately,it probably takes 1 hour atleast for bsnl people to activate the number,so 825 recharge wouldnt probably succeed.. Gen next portal will show you if any plan is currently active on your no btw. Also 825 plan can be availed via the portal for 734rs from main balance (waiver on service tax).
