i wish to ask , which telco prepaid company line offer the Longest VALIDITY Period ?
As i need a Line for RECEIVE call only . Calling out is Not necessary.

As if i keep on reload into my line and it will be a waste .
Please Recommend me with any package that will able to maintain longer validity period (Receive call Period) so that other ppl can call me

Is there any Special promo / offer for this ?

thanks .
