if someone calls your old number, they receive a text message informing them of your new number 075*******. You also receive a text that number 07******** called your old number. That's all it does

once you activate imoved, you need to switch off your old number. You won't receive sms's because the service does not forward sms's from your old number to your new number. YU network sends you and the person who tried calling you an sms informing you of someone who called your old number because its already switched off. The caller also receives a sms from YU network informing him/her of your new number

@Jaguar,
Service kalulu.Not working....

@Jaguar,
There is some credit in the number and true i received two "successful" confirmation texts.Final step was diverting all calls to 0750008000 which i also did.Guess what,from then on,people calling me from YU lines could not go thru and the message was "error in network connection".This went on until i cancelled the divert.I am not giving up and as you've suggested,let me try the process all over again.....As for calls to 100,all i get is voice service which is of no help while calls to helpline 0750100100 went "the person you have called is not available" (HOW??? ).Most unfortunate is there is no e-address where i can post my complain(Again, HOW in this age and time???).....Very Pocket friendly though.

Mcreggae,
Just being pennywise....Want to maintain Zain and YU.
